compensation.8. Thou shalt not appropriate other people's intellectual output.9. Thou shalt think about the social consequences of the program you are writing or the

system you are designing.10.Thou shalt always use a computer in ways that ensure consideration and respect for your

fellow humans.II. INTRODUCTION OF SYSTEM SOFTWARESystem software is any computer software that provides the infrastructure over which

programs can operate, i.e. it manages and controls computer hardware so that application software can perform. Operating systems, such as GNU, Microsoft Windows, Mac OS X or Linux, are prominent examples of system software.System software is software that basically makes the computer work. Besides operating systems, other examples are anti-virus software, communication software and printer drivers. Without the system software the computer doesn't work. In contrast to system software, software that allows you to do things like create text documents, play games, listen to music, or surf the web is called application software.In general application software are programs that enable the end-user to perform specific, productive tasks, such as word processing or image manipulation. System software performs tasks like transferring data from memory to disk, or rendering text onto a display device.Types of system software

System Software can be classified as operating system, device drivers and utility software. An operating system creates an interface between user and the system hardware, while other system software will refine or allow greater interaction with the machine's hardware.System software helps run the computer hardware and computer system. It includes operating systems, device drivers, diagnostic tools, servers, windowing systems, utilities, language translator, data communication programs, data management programs and more. The purpose of systems software is to insulate the applications programmer as much as possible from the details of the particular computer complex being used, especially memory and other hardware features, and such accessory devices as communications, printers, readers, displays, keyboards, etc.

Specific kinds of system software include: Loading programs Operating systems (and their components, many of which are classified as system

software) Device drivers Linkers Utility software Desktop environment / Graphical user interface Shell

BIOS Hyper visors Boot loaders

If system software is stored on non-volatile memory such as integrated circuits, it is usually termed firmware.One characteristic in which most system software differ from application software is machine dependency

»         e.g. assembler translate mnemonic instructions into machine code»         e.g. compilers must generate machine language code»         e.g. operating systems are directly concerned with the management of nearly

all of the resources of a computing systemThere are some aspects of system software that do not directly depend upon the type of

computing system»         e.g. general design and logic of an assembler»         e.g. code optimization techniques

III. DATA COMMUNICATION AND COMPUTER NETWORKSData communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet.

IV. APPLICATION SOFTWAREApplication software is all the computer software that causes a computer to perform

useful tasks beyond the running of the computer itself. A specific instance of such software is called a software application, application program, application or app.

The term is used to contrast such software with another type of computer program referred to as system software, which manages and integrates a computer's capabilities but does not directly perform tasks that benefit the user. The system software serves the application, which in turn serves the user.

Examples include accounting software, enterprise software, graphics software, media players, and office suites. Many application programs deal principally with documents. Applications may be bundled with the computer and its system software or published separately, and can be coded as university projects.

Application software applies the power of a particular computing platform or system software to a particular purpose.

Some applications are available in versions for several different platforms; others have narrower requirements and are thus called, for example, a Geography application for Windows, an Android application for education, or Linux gaming. Sometimes a new and popular application arises which only runs on one platform, increasing the desirability of that platform. This is called a killer application.

V. MULTIMEDIAMultimedia refers to content that uses a combination of different content forms. This

contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms.

Multimedia is usually recorded and played, displayed, or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance. Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by including audio, for example, it has a broader scope. The term "rich media" is synonymous for interactive multimedia. Hypermedia can be considered one particular multimedia application.

VI. THE INTERNETThe Internet is a global system of interconnected computer networks that use the

standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), theinfrastructure to support email, and peer-to-peer networks for file sharing and telephony

VII. COMPUTER IN SOCIETYIn today’s society, the role of computers has changed the way one interacts with one

another. The computer was first created in the 1600s and simply referred to a person who carried out calculations or computations. It wasn’t until the 20th century that the computer took its role in society that it has now. Although the computer has brought good to the world, it has hindered the way people interact with one another on a day to day basis. At this rate the computer could make man obsolete. Society has built up this technological item to be the new thing and now there is no stopping it.

In the 20th century the computer we know today emerged and forever shaped the way people will live their lives. The computer has become one of the most used technological items in our society today behind the cell phone. A computer allows you to send and receive emails, keep up to date with your friends and most importantly receive the news. Through the use of social media people are only one click away from receiving all the information they could possibly need. The idea that by a click of a mouse it can connect you with a person on the other side of the world is an amazing achievement and shows how far our society has come.

Unfortunately with the good comes the bad, and in saying that the computer has limited the way people converse with one another. Through Facebook, Twitter and other social media’s we no longer get the face to face conversations as before. Getting to know someone has become harder even though the process of meeting someone is as easy as a click of a mouse. We are losing the deep connections that previous generations have, and often take things for granted because of the use of computers. Our society has become lazy and is dependent on everyone else but ourselves to make decisions.

If the computer continues to increase as it has over the past decade then it will make humans obsolete. Computers will have the ability to do jobs quicker and more efficient than humans, causing thousands of lost jobs and an economy that could be worse than the present one. People need to realize that with the good always comes the bad and if people keep developing computers the way they are it will eventually back fire. The biggest factor in the development of computers is society; the more society promotes the use of computers the less likely communication will ever get better and the ability for man to succeed. The key to success is the limitation of computer use and continual face to face communication.

In conclusion, the way we interact with one another has been heavily influenced by society through the use of computers. Starting with the first computer in the 1600s to the present day computer, the name has stayed the same but the purposes have dramatically changed. The present day computer has changed the way one will interact with one another forever. This interaction though has been hindered by the computers because it has limited the face to face transactions. The future can only be changed by our present and the way society is going it does not look good for mankind. Although the computer has brought information by a click of a mouse, that same click of a mouse could change the way the world interacts for years to come.

IX. MICROSOFT EXCELMicrosoft Excel is a spreadsheet application developed by Microsoft for Microsoft

Windows and Mac OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office.

Microsoft Excel has the basic features of all spreadsheets,[2] using a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering and financial needs. In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display. It allows sectioning of data to view its dependencies on various factors for different perspectives (using pivot tables and the scenario manager).[3] It has a programming aspect, Visual Basic for Applications, allowing the user to employ a wide variety of numerical methods, for example, for solving differential equations of mathematical physics,[4][5] and then reporting the results back to the spreadsheet. It also has a variety of interactive features allowing user interfaces that can completely hide the spreadsheet from the user, so the spreadsheet presents itself as a so-called application, or decision support system (DSS), via a custom-designed user interface, for example, a stock analyzer, [6] or in general, as a design tool that asks the user questions and provides answers and reports. [7][8][9] In a more elaborate realization, an Excel application can automatically poll external databases and measuring instruments using an update schedule,[10] analyze the results, make a Word report or PowerPoint slide show, and e-mail these presentations on a regular basis to a list of participants.

X. MICROSOFT POWERPOINTMicrosoft PowerPoint is a slide show presentation program developed by Microsoft. It

was officially launched on May 22, 1990, as a part of the Microsoft Office suite.PowerPoint presentations consist of a number of individual pages or "slides". The "slide" analogy is a reference to the slide projector. A better analogy would be the "foils" (or transparencies/plastic sheets) that are shown with an overhead projector, although they are in

decline now. Slides may contain text, graphics, sound, movies, and other objects, which may be arranged freely. The presentation can be printed, displayed live on a computer, or navigated through at the command of the presenter. For larger audiences the computer display is often projected using a video projector. Slides can also form the basis of webcasts.

PowerPoint provides three types of movements:1. Entrance, emphasis, and exit of elements on a slide itself are controlled by what

PowerPoint calls Custom Animations.2. Transitions, on the other hand, are movements between slides. These can be animated in

a variety of ways.3. Custom animation can be used to create small story boards by animating pictures to enter,

exit or move.PowerPoint provides numerous features that offer flexibility and the ability to create a

professional presentation. One of the features provides the ability to create a presentation that includes music which plays throughout the entire presentation or sound effects for particular slides. In addition to the ability to add sound files, the presentation can be designed to run, like a movie, on its own. PowerPoint allows the user to record the slide show with narration and a laser pointer. The user may customize slide shows to show the slides in a different order than originally designed and to have slides appear multiple times. Microsoft also offers the ability to broadcast the presentation to specific users via a link and Windows Live.
