Sign up to get notified when this product is back in stock. Quick Overview. This revised edition incorporates the most recent feedback on user requirements and up to date information on advancements in the field of information and communication technology. The presentation and language continues to be lively, simple, and easy-to-understand.
The text is well-supported by comic strips, icons, cartoon characters, and illustrations, making the learning process an enjoyable experience. Each Student Book is accompanied by a digital learning resource that offers interesting animation, informative tutorials, and interactive tests for the student to supplement classroom instruction with independent learning.
The Teaching Guides are also accompanied by a Digital Teaching Resource that offer a wealth of learning and assessment material. An innovative Test Generator enables teachers to produce test papers from an extensive pool of questions for each chapter and section.
More and more users wanted more graphics; programmers and developers wanted more powerful language that can make larger programs easier to develop, manage, and maintain. This programming language was created with the main purpose of teaching programmers and developers how to design and develop graphical-user interface GUI programs easily.
The reason behind the GUI name is that we work more with graphics, forms, and icons, than typing text to accomplish a particular task. In GUI approach, rather than trying to remember a hard to remember command and its corresponding parameter, we can remember easier by using pictures, objects and images.
This language was invented by Anders Hejlsberg and Scott Wiltamuth — the two distinguished Microsoft engineers. Anders Hejlsberg is legendary in the circle of programming language invention arena, because he was the one who created Turbo Pascal programming language and lead-creator of Delphi IDE at Inprise company formerly Borland International.
The objective of C is to provide an object-oriented, Internet-centric, high- performance and yet simple language for the. NET framework development environment. Most of the work of the web page designer and developer can be done by the guide of a wizard or with a combination of hard- coding. This will make web page and website development easy and fast, adding more productivity to the developer or designer. Errors will also be automatically highlighted with some color usually in red , to make you easily visualize them.
In an IDE, some of the code with ready-made templates will be automatically provided to you. You just have to invoke them. One of these templates are the Get and the Set methods which functionality is about assigning and initializing values to particular parameters, variables, or objects.
James Gosling of Sun Microsystems, in early s. It was designed to run on almost any computers and in any operating systems, or literally speaking- in any hardware or software platforms you are using. Java is primarily designed as a programming language for Internet-based program development.
Meaning, from the ground-up, its strength lies in its ability to work with the Internet technology and its inherent idiosyncrasies. In Java, we can write program called applets. The applet can be embedded in web pages to provide some intelligence, so that the web pages we designed becomes dynamic, animated, or alive in the face of the website visitors and web surfers. This will not limit to animation and graphics alone, but also to interact with the user or surfer.
In other words, to become interactive with the visitors where they can input data, and get a reply or result from it. The Java application programs are stand-alone programs that we can run in any platforms. This further means that the application program will run without any modifications or problems to any software or hardware where we implement it.
The good thing about Java application program is that we can develop and implement it in a stand- alone computer or network computers. In other words, Java application programs are not Internet-based programs like the applets do. This short discussion of Java capabilities cannot justify its immense power. In reality, Java is so very powerful. It can do a lot of things that you can imagine. Afterall, this is a book about introductory computer concepts and applications, not an intensive discussion and treatment about Java programming language.
I explain Java programming in that book in a way that is easy to learn, understand, and enjoyable to program with. I promise. These capabilities of Python language are suitable for scripting operating system administration tasks or as a glue language to connect system components together.
One of the most outstanding features of Python is its simplicity in the implementation and design. For example, it is easy to debug your Python program, because any error or bad input data found in your program will not cause a segmentation fault. Instead, the Python interpreter will simply raise an exception when an error or bad input occurs.
And if in case the Python program was not able to raise an exception, the Python interpreter will simply print a stack trace for a programmer to easily trace the error in his or her program.
Note: The exception is an error-handling mechanism within your program. Usually, this exception code is written with the combination of try-catch and finally statements. The Scripting Languages The scripting languages evolved during the Internet revolution. They were the languages used so that the Internet or the World Wide Web became available for us to see it, enjoy it, and having fun with.
We will use HTML in writing simple web pages. These common styles or elements are the tags, headings, paragraphs, lists, tables and character styles fonts such as boldface, italics, or underlined. The HTML describes also the structure of a document. Markup language means that we start with the text of our page and add special tags around paragraphs and words.
The tags indicate the different parts of the page and produce different effects in the browser. This indicates the elements or features of a page. The pages written in HTML are plain text file. They can be read by any text editor that supports text writing.
Each HTML page needs a title to indicate what the page describes. The title indicates what the web page is about and how it is used to refer to that page in bookmark or hotlist entries. With the use of JavaScript, we can create dynamic and interactive web pages such as validate information in our Form that is filled- up and submitted by a visitor of our website, add alert boxes to our web page, customize reactions to mouse actions and keystrokes, perform calculations, and much much more.
The JavaScript was developed by Brendan Eich at Netscape Communications in , the company that releases the first world renowned web browser — Netscape Navigator. In other words, you can apply your OOP knowledge and skills in designing and developing JavaScript code.
This PHP is an embedded and a server-side scripting language which goal is to allow the Web developers to write dynamically generated pages quickly and efficiently. Most of the command and function syntax of PHP are borrowed from C programming language, Java, and Perl scripting language.
His original main purpose of inventing this scripting language is to be able to monitor the Web page views. However, it was developed into a more powerful language that is capable of developing dynamic web pages and database connectivity in a simple and straight-forward manner. Meaning, the designer and developer of the web page and website will create the tags only if they are needed for his or her applications.
This is how the XML developer would do to his or her documents, to structure it the way he or she wants it. Structuring a document is providing format to a document. This formatting process will dictate how a document must be processed, manipulated, or presented. Like for example, the price tag means a price tag in XML.
The CGI scripts enable our reader to interact with our web pages. These interactions can be a simple search for a chunk of information in a database, or to select an item from a form and get a reply in return, or to offer a comment on what we have written. When we encounter a search dialog or a fill-in form in case of membership application on the web, then we have to use a CGI script in real application. The script is usually a link between the server and some other program running on the Internet system.
This is usually a database program. The script performs some action based on the input from the browser. The action includes calling other program from the system, querying a database information, or calculating a value. The script also generates an output which the server can understand. When the server receives the output from the script, it passes back to the Web browser. Finally, the browser formats and displays the output for the readers.
They are not originally part of the scripting language that revolutionizes the Internet technology. Though, in one way or another, they are used in some cases to accomplish some Internet-related processes, they cannot be classified as scripting language for the Internet web design and development purposes. Authoring Software The authoring software is a special-purpose programming tools for creating computer-based training CBT programs, Web pages, and multimedia applications.
Using authoring software such as the Adobe Director, we can create multimedia titles combining music clips MP3s , animation avi files or MP4s , graphics, and text messages - all in one application.
Plus, the code of the application is written automatically. These authoring tools allow the designer and developer to visually write Web pages, most especially if he or she wants to create forms, tables, and other components for HTML pages. The Operating System The Operating System is a collection of programs that perform a variety of tasks or functions. The tasks performed by the operating system OS involve communicating with the disk drives, printers, hard disks, CD-ROMs, monitor, modem and other peripheral devices.
The operating system performs also memory management task such as keeping track of how the memory of the computer is being used so that no job would conflict with another job performed at the other parts of the memory.
Moreover, operating system performs data management. It provides a level of system security that protects a certain type of data or information. It acts like a clerk locating and accessing files and programs which are requested by the user. Unlike in Windows operating system, we just simply use the mouse to point and click and drag to accomplish the above mentioned task. There are two versions of DOS that reigned as an operating system of choice during that time.
The DOS operating system suffered a lot of weaknesses or limitations. For example, it supports a limited amount of RAM, it has no built-in support for networking and supports only bit programs. In August , the Microsoft released their Windows A total enhancement of the Windows 3. This time, the DOS is no longer needed for its installation, configuration and operation. Windows 95 puts all data communication activities in a single screen icon.
These activities are e-mail, downloads, and Internet access. This concept lets the computer to configure itself when a new computer peripheral is added, connected, or installed. Windows 98 is considered just an update to Windows The Windows Me Millennium Edition offers ore enhancements such as digital video editing, improved multi-media support and capabilities, and enhanced Internet features. The main problem with Windows Me is that its unstable operation results to frequent crashes. The Windows Professional combines the user-friendly interface of Windows 98 and a networking power of Windows NT.
With the release of Windows XP Home Edition for personal use and Professional Edition for corporate networks operations in October , the PC desktop has more three-dimensional 3D look, with more shading and rounded corners, and offers more brighter color choices.
It supports bit CPU. With its digital media support, the user can take advantage of video and audio rendering rendering for multimedia projects and digital broadcast support. The Advanced Networking and Communications feature of Windows XP, the user can now enjoy the more enhanced Plug and Play support which enable the computer to find and use the hardware connected via a network, without forcing the user to configure the sysem or install the required drivers.
With the Internet Connection Sharing feature, the user can connect multiple PCs to the Internet via a single connection. Through the use of Advanced Mobile Computing automatic configuration feature, the user can connect an XP-based Laptop to a PC without the need to know different type of network settings.
Plus the IrComm modem support will allow us to use a cellular phone to connect to the Internet. By using Windows Vista, we can access the Support Online Web site for answers to our common questions. It has tools that can help us to regularly test our hard disk and check system files. Plus, it can even correct some of the problems found. Windows Vista is a truly Web integrated.
The Internet connection wizard makes the connection to the Web fast and simple. Using Microsoft Outlook Express, we can send e-mails to our friends or post messages to the newsgroups in the Internet.
With the use of Microsoft NetMeeting, we can collaborate with others on documents edited by teams. Plus, we can even hold a teleconferencing over the Internet. Using Microsoft NetShow, we can play live media over the Internet. Windows Vista supports DVD technology and high definition digital audio, so we can play high quality digital movies and music on our computer.
Windows Vista includes a wide range of helpful troubleshooters that assist us with common computer problems. When we have difficulty setting up a new high-tech printer, the Print troubleshooter can walk us through the process step by step.
The Windows Vista includes the Discover Windows Vista online tutorial, which teaches us about the basics of Windows operating system. The Web pages that we subscribe to can be automatically downloaded to our computer or sent via e-mail.
By subscribing, we are free from the hassle processes of downloading, connecting times, and busy Web servers. In Windows Vista, we can browse the computer contents the same way we surf the Web sites.
It offers also some brighter color choices. It supports also the capabilities of a new microprocessor in bit to take full advantage of it. With Windows Media Player 11, users can take advantage of digital broadcast support, as well as video and audio rendering for multimedia presentations.
Windows Vista enables the computer to find and use hardware connected via a network by taking advantage of the universal Plug and Play support feature. The automatic configuration feature of mobile computing in Windows Vista makes it easy to connect to the Internet on this present time of wireless technology. In addition, we can protect our data, programs and other files through its complete PC Backup and Restore feature. This particular feature is ideal for disaster recovery when our PC malfunctions.
This feature is a critical first-line of defense to protect our PC against many types of malicious software such as viruses, Trojan, and worms. Discover the other features by yourself. Are you ready now? After-all, movie-making is a team effort. It takes only a single click to create a new playlist of your favorite music album or your most played tracks of songs.
Linux can run on nearly any type of computers from Desktop, Laptop, Server, and Supercomputers , and supports almost any type of software applications.
Most of the Linux distributions are free. Meaning, you can get it without worrying about licenses or online activation. It is also heavily used in a mission- critical applications such as Web servers that are used for online transactions, maintaining Internet domain names, large database servers of banks, manufacturing companies, and pharmaceutical firms.
The Mac OS is heavily favored by graphics artists, multi-media developers, and media publishers. This is due to its highly powerful graphics features and capabilities. Graphics artists who created cartoon movies and TV cartoon series, TV, magazine, and newspaper advertisements, are using iMac computers as their tools for their creative works. Most of the popular router and switch are designed and developed by Cisco Systems, the world leader in Internet device design and manufacturing.
It is called the Cisco IOS. A router is simply a special type of computer with very specific function and purpose. Like the computer we use that needs an operating system to run, the router needs an OS to run too. The router needs the Cisco IOS to run configuration files that contain instructions and parameters that control the traffic in and out of the Cisco router or switch. The configuration files specify all the information for the correct setup of selected routing protocols on the router to communicate with other routers, successfully.
By using routing protocols, the router can decide effectively how to send the packet that contains data or information to the best path to reach its destination in a fast and efficient way.
The first one is the Workstation OS which are used primarily by computers that are not connected to the networks. These are usually the type of operating system that we used at home, or installed in our laptops.
It is specifically designed for a computer workstation that connects to the server in the network that needs system security settings. Network servers act as the main computers used in the company.
The most famous server operating systems are still from Microsoft. They are the Windows Server and Windows Server The third in the category of an operating system is the one used for PDAs, cell phones, bar-code readers, and electronic devices found in automobiles. It is called the embedded operating system. The most popular embedded system are Windows CE. The last category is an operating system called the Internetwork Operating System IOS which specific application is in the Internet devices called routers and switches.
Because of the IOS that powers up the router and switch, the computer connected to the Internet can communicate to each other, regardless of distance or time. The router and switch made this possible. Utilities Software The operating system has already the utility software programs included in its package. These utility programs perform system maintenance, repair, enhance or extend the capabilities of the operating system.
The utility software is used when damaged system files happened during the time we forget to shutdown our computer properly. This would result to many bad sectors and lost clusters in our hard disk. This is reported during the time we boot our computer. When the damage is a severe case, it is advisable that we have to reformat and repartition the hard disk. Although some of the stored or saved software and data can be back-uped, the affected files are possibly cannot be restored.
There are commercial utility programs such as the famous Norton Utilities that can repair these affected files. You have to purchase this utility software separately. The Norton Utilities can diagnose and repair damaged disk, recover files that have been accidentally deleted, resurrect a crashed hard disk, and optimize hard disk drive performance by defragmenting the disk. They can enhance or extend the capabilities of the operating system.
The antivirus utility can examine or check the contents of the hard disk, USB drive, and RAM for hidden viruses that might be lurking on these storage devices.
The firewall software or hardware or a combination of both , can examine or block traffic coming from or going to the Internet. In this way, your computer could detect and will inform you if you are being attacked by a hacker or simply an intruder that violates your right to privacy. They are used in downloading files in the Internet in a fast and easy way. The typist will no longer suffer the agony of retyping the text to produce clean and a net draft.
Through the use of word processing software such as the Microsoft Word and its OpenOffice counterpart, a user typist can concentrate on thinking about the ideas and let the computer handle the details of laying out the words and spacing neatly on the page. This can be accomplished because we can easily insert text at any point in the document, delete text from any part of the document, move text from one part of the document to another section of the same document or to another document, search and replace selected words or phrases throughout a document, copy text from one part of a document and duplicate it in another section of the document.
These are but the basic features of word processing software. As a matter of fact, there are dozens more capabilities a word processor can do such as automatic underlining of important words or phrase, changing fonts and sizes, adding colors to any words you want to be highlighted, automatic footnoting and hyphenation, and automatic checking the spellings of all words you typed in the document, and the ability to incorporate graphics or picture created with other software applications.
Microsoft Word A Real-World Example of a Word-Processor The Microsoft Word is a full-featured word-processor designed to help us work efficiently with our paper works in the office. Typing text in MS Word is similar to typing on a mechanical typewriter. The letter arrangement of the keys is the same. So if we have a background in using a typewriter, it is easier for us to learn how to use the keyboard.
We could find that MS Word is easier to use than a typewriter. Moreover, it helps us to accomplish our task faster, more neat and presentable. For example, when we type enough words to reach the end of the line, MS Word automatically moves to the next line.
This feature is called a word wrap. The most outstanding feature of MS Word is its editing capability. If we change our mind after we write something, we can edit what we have written, delete the word or sentence we do not want or add a word or sentence to our document. And then the MS Word will automatically adjust the spacing of the text. We can also apply formatting to control the appearance of our document. We can format the text appearance by making it in italic, underlined, or bold form.
We can even specify to center the text, to left justify or to right justify the text. Plus, we can add or insert pictures and graphs to our documents. Not only that, the MS Word can automatically check the spelling of our text.
With this feature of MS Word, we can be perfect in our spelling. How about our grammar? Well, the time will come, the MS Word can accurately pinpoint our grammatical errors. For now, let us be just contented with what it can do. When an MS Word, finds a wrong spelling, it underlines the word with a red zigzag line. You could notice that it underlines your first name, last name, address or tagalog expressions you typed in your document.
This means that the spelling checker of MS Word can only understand English words and consider other foreign words as misspelled words as its default.
Now remember, MS word is like humans, it is not perfect the grammar correction pinpoints only some possibilities, not accuracy of pinpointing it. When selected, pointing the mouse cursor over a word will display its translation in the particular language.
With the Document Inspector feature, it can strip MS Word documents of information such as author name and comments. The feature of building blocks lets us save frequently used content, so that they are easily accessible for further use. The contextual spell checker feature catches incorrect usage of correctly spelled words.
With MS Word , we can write directly our blog entries to a blog sites. These are but just few of the features of MS Word Note: This book is written using MS Word ! You oftenly encounter this type of document when you are downloading a document from the Internet. Before the advent of personal computer, publishing required expensive equipments and highly trained personnel to operate the equipments. A modern desktop publishing system includes a computer, a laser printer, and a desktop publishing software.
A highly knowledgeable person can possibly do all the writing, editing, graphic production, page layout and typesetting a desktop publication.
It has all the tools needed by the presenters to show sales figures charts, profits and losses analysis, and any presentations for business meetings. The PowerPoint has text handling, outlining, graphing, and drawing features. We can refine the content of our presentation by rearranging and editing text in the Outline and Slide views menu.
We can even move the slides around in the Slide Sorter view to adjust to the look we want. In our presentation, we can add clip art, drawings, graph and charts. We can even produce speaker notes pages and hand-outs to support our presentation.
It has also a Wizard to help us organize and design our presentation task in a step by step manner. The PowerPoint has five views to assist us in our presentation task. The first one is the Slide view that allows us to work individual slides. Second, is the Outline view that allows us to work on the title and body text of our presentation. Third, the Slide Sorter view allows us to organize each slide of our presentation. Fourth, the Slide Show view will display our slides.
The new Microsoft Power Point can now render 3D graphics. It can support for tables pasted from Microsoft Excel The Slide Library feature lets us reuse any slide or presentation as a template.
Any of our presentation or slide can be published to the Slide Library. Now in PowerPoint , we can sign our presentation digitally. There is an added support for Widescreen slides and allows us of custom placeholder. A spreadsheet document called worksheet are composed of numbered rows and alphabetically lettered columns.
The intersection that forms a highlighted box is called a cell. For example, the cell B2 means the intersection of column B, and row 2. A cell can contain a numeric value, a formula or a label. The worksheet must use a formula to compute a group of numeric values in vertical or horizontal listings.
This formula commands the computer to add numbers in cells B1, B2, B3, B4, and B5, then divide the total by 5. And finally displays the resulting computation in the cell B7 where the formula was located. We cannot see the formula in cell B7, we can see just the computed value. Most of the spreadsheet software contains the following features: automatic replication of values and formulas, automatic recalculations, predefined mathematical functions and macros.
Spreadsheet software includes a feature where we can turn the figures in our worksheet into a graph or chart automatically. These graph can be a line chart, pie chart, or bar chart graph. The Excel software is under the spreadsheet category. It displays data in row-and-column format, with gridlines between rows and columns, similar to accounting ledger books or graph paper.
Excel is primarily used for numeric data in accounting tasks, statistical computations, and even in scientific research. In Excel, we use workbook or group of worksheets.
A worksheet is a grid of rows and columns in which we can type the data or value. The cell is designated by a thick border, and it is the intersection of rows and columns in a worksheet. An active cell is a cell in which you can enter data in a worksheet. Excel provides capabilities for moving the existing content of one or more cells to a different location. This approach is called cut and paste because you cut or remove data from its original location, and then paste or insert the data at a different location.
A font is a general appearance of text, numbers, and other character symbols. To make our worksheet attractive, we have to change the font and font size for selected headings, labels, and values. Using the AutoFormat feature, we can format the data in our worksheets, applying a professionally designed template.
It adds different colors, shading, and font effects to provide clarity and visual appeal to the worksheet. The Microsoft Excel contains graphing functions too, which has its own ChartWizard. With the use of ChartWizard, Excel can walk us through the four necessary steps required to create a chart graph. Excel has a database manipulation capability. It can organize the data or information in systematic way. In other words, Excel spreadsheet software can store and retrieve data, in the same way we use database management system software such as Microsoft Access or Microsoft SQL Server.
But maybe not that good enough like the way Microsoft Access can do. The color scales will automatically color the background of a group of cells with different colors. The icon sets will precede the text in a cell with an icon that represents some aspect of the value of the cell.
The data bars show a gradient bar in the background of the cell. The Formula Auto-complete feature of MS Excel automatically suggests function names, arguments and name ranges and automatically completing them if desired. The Page Layout View feature shows the spreadsheet in a way that mirrors the formatting that will be applied when printed. The Quick Filter option allows the selection of multiple items from a drop down list of items in the column.
The option to filter based on color has been added to the choices available. Its new charting engine feature supports advanced formatting, including 3D rendering, shadows and transparencies. The chart layouts can also be customized to highlight various trends in the data. This is handy if the function needed by the user cannot be found in Excel There are other application software that are bundled with Microsoft Office which most of us are not aware of or not familiar with. This is regardless of their respective location or what company they work for.
They can collaborate with the team members even if they work offline or working away in other site. With Office Groove , the team can keep the files, tools, and information in one place and can be accessible anytime and anywhere, with the most up to date revision available for each and every member. This is possible with the synchronization feature.
With the new feature such as the Instant Search, you can organize your e-mails and view them alongside with your other e-mail accounts, plus, the ability to access your information even when you are offline. With Office Outlook , you can also track business data and manage sales using the Business Contact Manager feature. You can add drawings, pictures, audio, or movie to the information you gathered with Office OneNote You can also perform some calculations using the calculator capability of OneNote.
This is handy if your notes need some calculations. With Office OneNote, you can easily gather, search, and share notes and information wherever you are, conveniently. You can create any publication materials for e-mail, print, and the Web, informing or even yet, enticing your target customers about your products and services.
With Office Publisher , producing marketing campaign materials is so easy, fast, and professionally designed by you. These people could be your customers, clients, suppliers, partners or colleagues. Some application of Office InfoPath is when you want to create a Form template Christmas party expense reports for the employees in your company.
Most of us are not using it directly. Some company departments are using Office Access for managing departmental data and record keeping operations. It has inherently limited capability to handle small database files a typical of a few thousands of records with up to 10 database users are allowed to access the database engine of MS Access simultaneously. They are both an office suite application software. The OpenOffice supports the OpenDocument standard which further means that it is compatible with Microsoft Office document.
In other words, you can open your Microsoft Word document to OpenOffice word- processor without encountering any problems, and vise-versa. Like the Linux operating system, you can acquire the OpenOffice for free. So download it now!
Try it! Accounting software automatically adjusts the balance in every account after a transaction so that the history can be traced later when the demand or need arises in the near future. Aside from fast and easy record-keeping, financial management software can automate the generation of check writing, budgeting, and bill paying. Example of this application software is Quicken and MS Money. Mathematical processing software are used by many professional and students whose needs are beyond the capabilities of spreadsheet software.
This software can handle complex equations, formulas, and calculations. Mathematicians can easily create, manipulate and solve equations, the same way the word processors help the writers. These software can handle the calculations for matrix and linear algebra, complex trigonometry and polynomial factoring. Statistics is the branch of applied mathematics and considered as the science of collecting and analyzing data.
Statisticians depends heavily on computers in speeding up the collections and analysis of raw data. Statistical analysis software can produce graphs that shows how two or more variables relate to each other.
The statisticians can analyze and uncover trends by looking for unusual patterns in the graph of dots and lines that appear on the monitor. Scientific visualization software uses location in space, shape, and color to help us understand the relationship of things and objects that are invisible in our eyes.
The user usually used or wears some polarized lenses or electron microscope that are connected to the computer. This peripherals will permit the user to see three dimensional 3-D images of molecules to be analyzed. In some application that study the outer-space, this peripheral can be used to see and observe the mysterious clustering of galaxies. This visualization software can help the researcher to see the relationship that might have been obscure to grasp without it. Computer Modeling and Simulation software is use to create abstract models of objects, organizations, processes, and organisms.
A statistician who examines and analyzes the data collected from the respondents has created statistical models to describe a particular trend or phenomena. An engineer who uses mathematical and engineering software can test the stress capacity of a bridge before it is constructed.
Most computer games are models or simulations of an actual or imaginary ideas, processes, works, or situations. Chessboards, ballgames, sports arenas, battlefield, medieval dungeons, mythological societies and interplanetary cultures have been modeled through computer games.
This computer model is an abstraction to reality, which means that it is a set of concepts and ideas designed to emulate an actual situation.
User- oriented simulations allow the person to temporarily live their fantasies. Sports simulation like the world re-known athlete stars are among the favorite computer games of the new generation today. In military application, the fighter jet pilot can simulate the right and safe landing of F14 in an aircraft carrier using the computer.
Database Management System A database management system is a type of software that is used for organizing storage and retrieval of information. In other words, this software allows people to store, search, retrieve, process, or access data fast and easy. To store and retrieve the information in a fast and easy way from the Internet, database management system is applied. Take for example, with the Google. In Google, you just simply type the word or words that you would like to search.
In a matter of seconds, you will get the list of links to choose from so that you can narrow your search to find what you searched for. A database is considered as a computerized version of an inventory file stored in an office file cabinet, a library card catalog or a card index containing the names and addresses of business contacts.
Here are the basic components of the database management system: a. Database — is a collection of information stored in a systematic form in a computer. Table— a complete collection of related records in a row and column format. Record — is a collection of related data about a person or object.
