Topic One

GENERATIONS OF COMPUTERS

The first generation computers used vacuum tubes. They were very large in size and programming on them was very difficult. Some of the computers of this generation are as follows:-· MARK – I :

This was the first electronic computer developed by Howard Aiken. It was about 15metres long and the wires connecting the various parts of the machine were about 800 Km long. The main advantage of this computer was that it was fully automatic and much more reliable than other electronic computers.

· ENIAC : This was the first fully electronic digital computer developed by J.Presper Eckert and John Mauchly. The full form of ENIAC is Electronic Numerical Integrator And Computer. It contained approximately 17,500 vacuum tubes, occupied 680sq.ft area and weighted more than 27000Kg. Since ENIAC was initially not a stored program machine, it had to be programmed by manual rewiring for each task.

Picture 1.1

· EDVAC : EDVAC was also developed by the makers of ENIAC. It was a stored program machine unlike its predecessor. The full form of EDVAC is Electronic Discrete Variable Automatic Computer.

Picture 1.2

• UNIVAC I :UNIVAC was the first commercially available electronic computer developed by J.Presper Eckert and John Mauchly. It was also the first computer to handle both numeric and text data. The full form of UNIVAC is Universal Automatic Computer

Limitations of first-generation computers· The major limitations of first generation computers were :· The operating speed was very low.· Power consumption was very high.· They required large space for installation.· The Programming capability was quite low.· Quit larger, they generate lot of heat require special housing.· The Medium internal store.

Second Generation Computers (1956-1963) The invention of Transistors marked the start of the second generation. These transistors took place of the vacuum tubes used in the first generation computers. First large scale machines were made using these technologies to meet the requirements of atomic energy laboratories. One of the other benefits to the programming group was that the second generation replaced Machine language with the assembly language. Even though complex in itself Assembly language was much easier than the binary code. These generations are categorized by their technology as follows:

• ICT(ICL) 1300, • IBM 1401

Limitations of second-generation computers were : They used transistors as their main component.

They were smaller, faster and more efficient than first-generation computers.

They also contained all the components we associate with modern-day computers like printer, memory, disk storage, operating system.

They are cheaper than the first generation computers.

Maintenance requirement is still high.

Very costly.

Third Generation Computers (1964-1971) Although transistors were great deal of improvement over the vacuum tubes, they generated heat and damaged the sensitive areas of the computer. The Integrate

12


Circuit(IC) was invented in 1958 by Jack Kirby. It combined electronic components onto a small silicon disc, made from quartz. More advancement made possible the fittings of even more components on a small chip or a semi conductor. Also in third generation computers, the operating systems allowed the machines to run many different applications. These applications were monitored and coordinated by the computer's memory. These generations are categorized by their technology as follows:

• IBM-360 series, • ICL – 1900, • ICL – 2903, • PDP – 11/45

Limitations of third-generation computers were : · They used Integrated Circuits, popularly known as chips.· These computers were smaller than the second-generation computers.· Capacities of main memory were greatly enlarged.· They used an operating system that allowed machines to run many

different programs simultaneously.· Power requirement became less.· Maintenance of IC required sophisticated technology.

Fourth Generation (1971-Present) Fourth Generation computers are the modern day computers. The Size started to go down with the improvement in the integrated circuits. Very Large Scale(VLSI) and Ultra Large scale(ULSI) ensured that millions of components could be fit into a small chip. It reduced the size and price of the computers at the same time increasing power, efficiency and reliability. "The Intel 4004 chip, developed in 1971, took the integrated circuit one step further by locating all the components of a computer (central processing unit, memory, and input and output controls) on a minuscule chip."

Due to the reduction of cost and the availability of the computers power at a small place allowed everyday user to benefit. First came the minicomputers, which offered users different applications, most famous of these the word processors and spreadsheets, which could be used by non-technical users. Video game systems like Atari 2600 generated the interest of general populace in the computers.

13


In 1981, IBM introduced personal computers for home and office use. "The number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used." Computer size kept getting reduced during the years. It went down from Desktop to laptops to Palmtops. Macintosh introduced Graphic User Interface in which the users didn’t' have to type instructions but could use Mouse for the purpose.

The continued improvement allowed the networking of computers for the sharing of data. Local Area Networks(LAN) and Wide Area Network(WAN), were potential benefits, in that they could be implemented in corporations and everybody could share data over it. Soon the internet and World Wide Web appeared on the computer scene and formatted the Hi-Tech revolution of 90's.

Limitations of fourth-generation computers were : · They used Large –scale Integrated Circuits and Very Large –scale

Integrated Circuits (VLSIC).· They have very high computing power and extremely large memories than

earlier computers.· Storage devices have greatly improved and cost is less.· Computers can be linked together to share memory space, software,

information and communicate with each other.· Manufacture of LSI chips required sophisticated technology.

Fifth Generation (Present and Beyond) Fifth generations computers are only in the minds of advance research scientists and being tested out in the laboratories. These computers will be under Artificial Intelligence(AI), They will be able to take commands in a audio visual way and carry out instructions. Many of the operations which requires low human intelligence will be performed by these computers.

Parallel Processing is coming and showing the possibility that the power of many CPU's can be used side by side, and computers will be more powerful than those under central processing. Advances in Super Conductor technology will greatly improve the speed of information traffic. Future looks bright for the computers.

Topic Two

WHAT IS A COMPUTER

Computer can be defined as wholly electronic device or machine which process data supplied through any available input device such as keyboard etc into information, which can be stored in the CPU memory, and also retrieve it with output devices such as, printer, disk i.e. CD/DVD recordable, thumb drive (Flash drive).

On the other hand, it can also be defined as an electronic device that has the capability to accept data, store them execute a series of commands (Program), execute mathematical, logical operations on data given by the user and give information in the forms of an output. The output may be made obtainable either on the computer monitor or can be printed on a paper.Thus, computer is an electronic programmable device; it receives input from the client, stores and manipulates information. It provides output in a useful drawing. It can execute both mathematical and logical operations on the data given by the user.

Note: • Wholly Electronic Device:- This can described as machine or device which

performs logical and other calculating function.

• Process Data:- This process data supplied by the users, and data is a set of row unprocessed facts, figures and symbols. Computers process data to build information.

• Input Devices:- This input device is used for performing input of texts and other function with the availability of keyboard. However, there are other devices that can also play the role such disk, flash etc.

• Memory:- This is described as the brain box of the the system, where information are stored.

• Output Device:- This output devices are tools used to retrieve information saved on the memory for other purpose.

Digital ComputerA distinctive feature of a digital computer is that it computers by counting and adding operations. Digital computers are much faster than analog computers.

Picture 1.2.1

Analogue Computer

An analog computer computes by measuring changes in a continuous physical phenomenon such as electronic voltage, length, current, temperature, etc. The

16


devices that measure such quantities are analog. The advantages of analog computer are that all the calculation takes place in parallel and hence these are faster but their accuracy is poor.

Picture 1.2.2

Hybrid Computer

The hybrid computer uses both the analog and digital components. These computers use digital memory for the storage and analog devices for computational purpose.

Picture 1.2.3

Mainframe Computer These computers have high storage capacity. They process large amount of data at high speed. They are used in large companies, government departments, etc., as their main computer server. These computers need low temperature and special dust

17


free rooms. Numerous computers are connected with this computer. All the data of these computers are stored in it. These are faster and more sufficient than Minis and have a much large storage capacity. Examples are the IBM System /370 and IBM 4300 Series.

Picture 1.2.4

Super ComputerThe storage capacity of super computers is much more than micro, mini and main frame computers. Super Computers are the fastest of all and can process huge amount of data within a few seconds. They are used for handling complicated applications such designing the supersonic aircraft, weather forecast, etc. India has developed a super computer called PARAM. They are most powerful and most efficient too. They are designed to process complex scientific applications. They have the computing capacity of approximately 40000000 IBM PCs. Some examples are CARY-2, ETA-10, CARY X-MP.

Picture 1.2.5

Mini ComputerThese computers are more powerful than micro Computers and can support more than one user at a time. They have larger storage capacity. These computers are

18


used for variety of application. This machine is another advancement over the PC-AT. Here you can have a maximum of a few hundreds of dumb terminals attached to the same CPU. Processing speed is also many times faster. One example is the IBM 9375. Microprocessor used is INTEL 80286 or 80386.

Picture 1.2.6

Micro Computer There are different types of Micro Computer, such as 1. Desktop Computer 2. Laptop Computer 3. Palmtop

Desktop ComputerThese computers are popularly called PCs (Personal Computers). Compared to others, this is the smallest type. Inside it there is a single microprocessor, which functions like a CPU. These computers have low storage capacity therefore used as personal computers. It is a single user system. That is only one person can use it at a time.

TOPIC Three

COMPUTER TERMINOLOGY

In the past few years, computers have come down in price considerably and are now very affordable. Most people prefer to buy a PC for the home, though if space is at a premium and portability is important then you might prefer to buy a notebook (often called a laptop) computer. Both a PC and a notebook perform the same functions and have more or less the same features. It’s just that the notebook is more compact and is easily transportable for people on the move.

1. CPU This is described as central processing unit. It’s usually in the form of a tower, often called the ‘box’ or flat box, usually in horizontal stand. This performs logical and arithmetical operations though in some office environments you’ll sometimes see the box lying horizontally on the desk with the monitor placed on top. Inside the box lies all the computing power, with its micro-circuitry and tiny chips which can store vast amounts of information. If you’re the type of person who likes pulling cars apart, then you’ll probably be interested in what’s inside the box.

2. MONITOR The term "monitor" is often used synonymously with "computer screen" or "display." The monitor displays the computer's user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse.Older computer monitors were built using cathode ray tubes (CRTs), which made them rather heavy and caused them to take up a lot of desk space. Most modern monitors are built using LCD technology and are commonly referred to as flat screen displays. These thin monitors take up much less space than the older CRT displays. This means people with LCD monitors have more desk space to clutter up with stacks of papers, pens, and other objects.

3. KEYBOARD The keyboard is an input device designed to enter text, characters and other commands into the computer. The keyboard can be described as the primary device for inputting information such as texts: alphabets, numbers, symbols, and other signs, to the

http://www.techterms.com/definition/mouse


computer. It operates by converting key presses to electronic signals in binary digital form. The typical computer keyboard has the standard character keys found on a typewriter together with a number of special keys described below:

Keyboard Diagram

Picture 1.3.1

* Function keys : This contain F1 to F12 in numbers, positioned above the character keys, which can be programmed by the user or by the software being run, so that a single key depression sends a command or string of commands to the computer.

* The CTRL and ALT keys: (the full name is Control and Alternate), which are always used in conjunction with other keys to issue commands to the computer.

* The Backspace key, which delete the character to the immediate left of the cursor on the screen.

* The four arrow keys , which move the cursor one character position in the direction of the arrow.

22


* The PageUp and PageDown keys : This buttons are for programmed to move the cursor one page up or down i.e. the cursor will appear at the beginning of the message on the file page means the page up. And cursor disappear to the end part of the message on the file page means the page down.

* The Home key , which may be programmed to move the cursor to the left of the screen or the beginning of the document.

* The End key : which may be programmed to move the cursor to the right of the screen or the end of the document.

* The Esc key : which is often programmed to enable you to escape from your currently selected option or task.

4. MOUSE:This can be described as a hand-held device used for perform some special task in the keyboard options. The mouse operate with three button, such as right and left button, and center scroll. However, mouse are varies in shapes, sizes and function. Some come with two button, while some come with three.

• It is much easier to use than the keyboard for the following operations.• Pointing, that is, moving rapidly from one point to another in a word-

processed document, file of records r table of data.• Drawing, that is, creating lines and other shapes on the screen

Mouse Diagram

Picture 1.3.2

23


5. PRINTER:This is an output device used in printing document out of the CPU memory. It can also be described as output device which is used to produce hard-copy. However, there are different types of printers which performs different function, such as printer that printer only picture and graphic designed on the system. Some printers can only handle text whereas others can handle text and graphics.

6. SPEAKER:Speakers can be described as the small device plug into a computer system which is used for hearing and listening to the sounds of different types inside the computer. Speaker are mostly output devices, but few of the CPU has the built speakers.

7. MODEM:A modem is a device that allows a computer to communicate with the Internet and fax machines. There are several types of modems that serve different purposes.Dial-Up ModemThis is the most basic modem. It operates at up to 5 kilobytes per second and uses your phone line. You can send and receive faxes with this type of modem.DSL ModemDSL (Digital Subscriber Line) modem operates at up to 8 megabits per second. It sits between your computer and a phone line. It can be connected to a router so that other computers on your local network can access it.Cable ModemCable modem connects to your cable provider's network instead of a phone line. It has the same basic properties as a DSL modem.

Modem CardsA laptop has external slots that can contain wired or wireless modems. Wireless modems may use Wi-Fi or a cell phone network

Internal High-Speed ModemHigh-speed modems are typically external boxes, but you can find them in the internal variety for desktop computers. They usually use a PCI Express slot on the motherboard.

Topic Four

GETTING STARTEDHere, we will be looking at various ways and the functionality of the system. How we can get started with the system as a new user of the computer system. As we all know that, computer has lots varieties of tasks and functions its plays.

However, there are many programmes you need to be familiar on this topic, because in the section two, we will make use of those programmes mention in this topic.

To get started, there following rules to this level, and you need to be aware of these things.

Start Menu Diagram 1.4.1

The above diagram 1.4.1 shows the START MENU, which contains two wings; the Right Wing and Left Wing.

The Right Wings contains the My Documents, My Recent Documents, My Pictures, My Music, My Computer, My Networks Place, Control Panel, Printers and Faxes, Help and Support, Search and Run.

25


While the Left Wing contains the First partition Icon such as Internet Explorer, Email (Outlook Express) and the second partition Icon Paint, WordPad, Window Media Player, MSN explorer etc.

MY DOCUMENT

Is a Microsoft Windows folder that stores document, program settings, and other files that are used with many of the programs run on the computer. For example, when saving a file in Microsoft Word the default folder will often be My Documents. Saving all the personal files into the My Documents folder makes backing up and locating your personal files easier.

Using My ComputerOnce My Computer is open you'll see all available drives on your computer. For most users, you'll only be concerned with the Local Disc (C:) drive, which is the hard drive and what stores all your files. Double-click this drive icon to open it and view of its contents.

Tip: If you're looking for a document such as a word processor file you've created, music file, picture, or other personal file it's likely that it's contained in your documents folder. This folder is displayed in My computer as a folder and usually contains your name. For example, if your username was John, this folder would be named John's Documents.

Finding files in My Computer

If you're having trouble finding where one of your files is stored, use the Windows find feature to find the file. To do this from within My Computer either click on File and then Search or right-click on the C: drive or other folder you wish to search and click Search.

In the Search window, type the name or part of the name of the file you're trying to find.

Adjust system settings with your computer

If you wish to manage your computer or view other settings and information about your computer instead of double-clicking the My Computer icon to open it, right-click on the My Computer icon and click Properties. Performing these steps will open your System Properties (the same window accessible through the Control Panel

The Control Panel is a feature of the Windows operating system that allows the user to modify system settings and controls. It includes several small applications, or control panels, that can be used to view and change hardware or software settings. Some examples of hardware control panels are Display, Keyboard, and Mouse settings. Software control panels include Date and Time, Power Options, Fonts, and Administrative Tools.

MY NETWORK PLACES

My Network Places displays shortcuts to shared computers, printers, and other resources on the network. The shortcuts are created automatically in My Network Places whenever you open a shared network resource, such as a printer or shared folder.

The My Network Places folder also contains hyperlinks to tasks and locations on your computer. These links can help you view your network connections, add shortcuts to network places, and view computers in your network domain or in your workgroup.

Click the Add a network place task to start the Add Network Place Wizard. This wizard helps you to create new shortcuts to shared folders and resources on your network, Web, and FTP servers. If you don't have folders on a Web server already, the Add Network Place Wizard will help you create a new folder for storing your files online.

You can view, manage, move, copy, save, and rename the files and folders you have stored on a Web server just as you would files and folders stored on your computer. When you view the contents of a folder that is stored on the Web, the folder's Internet address is displayed in the Address bar.

Open My Network Places

Note• To open My Network Places, click Start, and then click My Computer. Under

Other Places, click My Network Places.

• The View workgroup computers task is displayed in My Network Places when your computer is in a workgroup and not in a domain. Double-click this icon to narrow your search to only those computers, printers, and resources that share a workgroup with your computer.

• If your computer is connected to a workgroup that has less than 32 computers, Windows will automatically create shortcuts in My Network Places to the shared resources in your workgroup.

WHAT IS ASERVER:Server is a computer designed to process requests and deliver data to other (client) computers over a local network or the Internet. Servers typically are configured with additional processing, memory and storage capacity to handle the load of servicing clients. Common types of network servers include:

• Web servers• Proxy servers• FTP servers• Online game servers

Server Diagram 1.4.6

CONCEPTS ON NETWORKINGLocal Area Network (LAN)LAN is a communications network serving multiple users within a confined geographical area (as in the same building or group of adjacent buildings). It usually refers to the interconnection of personal computers (usually called workstations). Shared data is stored in a high performance PC called a file server, which serves as a remote disk drive to all network users. Users may also share printers, modems and other peripheral devices. All these computers and devices are connected to a network backbone.

Local Area Network (LAN) Diagram 1.4.7

31


Wide Area Network (WAN)Several LANs can be linked together so that computers in one LAN can exchange data with computers in another LAN. Such inter-network is usually called Wide Area Network (WAN). An example of a WAN can be an education group wishing to connect all its schools over a wide area by one network. To do so, each schools' LAN are interconnected via dedicated lines offered by the telecommunication company

Wide Area Network (WAN) Diagram 1.4.8

Topic Five

ALL PROGRAMSAt this point, the student is required to pay more attention to details on this topic, here is the place users are mostly get started with all programs of the computer system. Any application, such as Notepad, Wordpad, Paint etc looking for, are insides the All Programs.

However, we will be looking at these following applications: Notepad; Wordpad; Paint in details, and the usage of each.

Meaning of Notepad

Notepad is a basic text editor that is embedded in Microsoft Windows. A notepad is a number of sheets of paper that are glued or stapled together on one edge. They are used for writing letters or the interim recording of information.

Notepad Diagram 1.5.1

33


Meaning of Wordpad

Is a basic word processor that is included with almost all versions of Microsoft Windows from Windows 95 onwards. It is more advanced than Notepad but simpler than Microsoft Works Word Processor and Microsoft Word. It replaced Microsoft Write.

FeaturesWordPad can format and print text, but lacks intermediate features such as a spell checker, thesaurus, and support for tables. As such, it is suitable for writing letters or short pieces, but underpowered for work that relies heavily on graphics or typesetting.

WordPad natively supports the Rich Text Format, though it does not support all the features defined in the RTF/Word 2007 specification. Previous versions of WordPad also supported the "Word for Windows 6.0" format, which is forward compatible with the Microsoft Word format

Wordpad Diagram 1.5.2

Meaning of PaintPaint is a simple picture-editing program which usually comes with Windows. It does not have any advanced features but it is probably all you will need. Pictures that are drawn or edited by Paint are called bitmaps. This means they are stored as

a grid of small dots, called pixels. Most pictures contain tens of thousands of pixels, and Paint needs to store the colour of all of them.

Paint Tools Diagram 1.5.4

1. Paint toolsThe paint tool looks like a paintbrush, and is the fourth icon on the right. Click on it and you will see a variety of shapes appear underneath the tools. Choose one of them and a colour from the palette at the bottom. Now click and drag on the main white area.

A few other tools work in a similar way. Next to the paintbrush there is a pencil, and you use this to draw a thin line instead of a thick one.

2. Text toolThis allows you to write on your picture. Click on the text tool (the "A") and drag out a large area on the picture. Type some writing. You can of course change the font, size and attributes of the writing using the new window that has appeared. If no new window appears, right click on the text area and click on "Text toolbar".

3. Selection toolsThese are the two buttons at the top, one being star shaped and the other rectangular. These allow you to select areas of the picture.

Click on one of the two tools and drag out an area, over some of the existing drawing. You will see that a dotted rectangle appears. This rectangle represents the selected area of the picture. Try pressing delete - it will disappear. If you like, you can undo this using "Edit", "Undo". You can do the following things to a selected area of picture:

• Cut or copy it to the clipboard, using the Edit menu. • Move it around. Simply click in the middle somewhere and drag. • Stretch it. Use the small blocks on the sides of the rectangle for this. • Stretch, skew, rotate, or invert the colours. This can be done using the

"Image" menu. If no area of the picture is selected, the commands apply to the whole picture.

4. Fill toolThis is the paint can under the rectangular select tool. Use this to fill an area of colour a different colour. Be careful - if you draw an outline of a shape and try to fill it, any gap in the outline will cause the fill to "leak" and cover the entire picture. Also, if an area has text on, the holes in the text (e.g. in the "O") will not be filled. You have to fill them all individually.

5. Pipette toolThis has the simple purpose of choosing a colour from an image. Click on this tool and then click somewhere on the picture. The tool will change to the tool you were using last, and the colour will change to the one you were pointing to.

6.Changing picture sizeClick on "Image", then on "Stretch/Skew..." and a new window will appear, into which you can type the new width and height, as a percentage of the current size. You can also skew the image using this window.

If you want to start a new picture which is a different size to the current one, click on "Image" then on "Attributes...". You can change the width and height here, and do not have to work it out as a percentage.
