1 HOW DOES A COMPUTER WORK? Hello, Kids! Remember me? I am Clicko. Today, we will learn how a computer works. Let Us Start Now, we are familiar with what a computer is and what its parts are. Can you identify the main parts of a computer? Let Us Do 1: Write the names of the parts in the given boxes. Today, computers are used in most places because they are fast, accurate and safe to work with. Do you know that a computer cannot work on its own? We need to enter letters, numbers and commands into the computer. This is called Data or Input. JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 7 1 14-12-2017 18:24:02

In this lesson We will learn about how a computer works in ‘Input-Process-Output’ Model. A computer works step by step. We can divide this whole process into three phases: 1. Input 2. Processing 3. Output IPO Model A computer is a machine that works on the principle of IPO or Input-Process- Output Model. The picture below shows the IPO model: Input Processing Output Some of our daily life activities also involve this IPO model. Let us see some examples.

Let us learn KRZ D FRPSXWHU SURFHVVHV LQSXW WR JLYH XV RXWSXW /HW XV DOVR ILQG out WKH GLIIHUHQW ,QSXW DQG 2XWSXWGHYLFHV Input Computers need data to work. Any data or information we send to a computer for processing is called input. Input is sent to the computer using an input device. Examples of input devices are: Figure 1.1 Input Example keyboard, mouse, scanners, video cameras and microphones. Processing Processing is the method of taking input data and changing it to output. It occurs in the CPU of the computer. CPU converts data from the input devices into useful information. What we see on the screen is the result of our given data. It is processed by some program so that we can have the output. 3 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 9 14-12-2017 18:24:02

Do You Know? ´7KHÀUVW&38ZDVGHYHORSHGE\\)HGHULFR Faggin and Ted Hoff in 1970.” Federico Faggin Ted Hoff Output Any information sent out from a computer is called output. It is the result of processing of the input. A simple example of the output is anything you view on your computer monitor. Figure 1.2 Output Example In the above Figure 1.2, data is being sent from a computer to a printer, which is called as output. This data is then printed onto a sheet of paper, which is also a form of output. Now, let us understand better with the help of an example: To know the result of 5 x 5, we type 5 x 5 = using the keyboard. So, “5 x 5 =” is the input and the keyboard is the input device. Now, the CPU solves this and gives you the result as 25. It displays the result on the monitor. Hence, 25 is the output, and the monitor is the output device. Glossary 1. Data – Information like your address, phone number, class etc. fed into the computer. 2. Input – Information sent to the computer for processing. 3. Output – Processed information sent out by the computer. 4. Processing – Act of taking input data and changing it into a useful output. 5.

3 HARDWARE AND SOFTWARE Friends, by now, we know about the different computer devices and the way they work. Do you remember the types of devices? Let’s recall and learn more about these. Let Us Start The invention of the computer has had a huge impact on our day-to-day lives. They are now present all over – at home, at work, and in school. ,QWKHÀUVWOHVVRQZHOHDUQHGWKDWFRPSXWHUZRUNVRQWKHSULQFLSOHRIInput-Process- Output model. It accepts data, processes and gives the result. Input devices are used to get data into the system. The output devices show results of processing. Do you remember the names of Input or output devices? Can you identify them? Let Us Do 1: List the devices and decide whether each device in the box is an input or output device. Device Input Or Output Keyboard, monitor, speaker, scanner, printer, 17 mouse, microphone, joystick, webcam, projector 14-12-2017 18:24:03 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 23

A computer system consists of two major elements. They are Hardware and Software. To make all input and output devices work together, we need both hardware and software. In this lesson We will learn ‡ 7KHKDUGZDUHDQGVRIWZDUHFRPSRQHQWVRIDFRPSXWHU ‡ )XQFWLRQVRIGLIIHUHQWFRPSXWHUSDUWV Hardware is the physical parts of the computer. Computer Software is the programs that run on a computer. Without hardware, the software would not be able to run. They need each other. Hardware Hardware Software Computer hardware refers to the electronic parts that we can touch and feel. It includes all the input and output devices that we learned earlier. The devices which are connected to the CPU by wires or wirelessly are known as Peripheral Devices. +DUGZDUHLVFODVVLÀHGLQWRIRXUW\\SHVRIGHYLFHV Do You Know? 14-12-2017 18:24:03 “Hardware also includes the cables, connectors, and power supply units.” 18 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 24

While processing, the computer saves the data or result in storage devices. Let us learn about them one by one. Input devices Input devices consist of external parts by which we give data and commands to the computer. Common input devices are Keyboard, Mouse, Scanner, etc. Keyboard The keyboard is used to enter data into the computer system. It can type letters, numbers, etc. Mouse The mouse is a pointing device. It is used to give commands to the computer. Joystick A joystick is used to play games on a computer. Scanner We use a scanner to copy a document and input it into a computer. Microphone The microphone allows us to input sounds as our speech and songs into the computer. Webcam A web camera takes pictures and puts it into the computer. Processing Devices CPU The Central Processing Unit called the brain of the computer is also hardware. It is the most important part of the computer. It controls all the other parts and does all the calculations of the computer. JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 25 19 14-12-2017 18:24:04

Output Devices Output hardware consists of devices that transfer information from the computer to the user. Below are some examples of hardware output devices: Monitor The computer displays the result of processing on a TV-like display screen called monitor. The monitor is also known as VDU (Visual Display Unit). Printer The printer can print the results of our work on the paper. The output is called a printout. Projector ,W WDNHV LPDJHV IURP D FRPSXWHU DQG FRSLHV WKHP RQ D ODUJH ÁDW surface. Speakers You can listen to music, speeches or sounds from a computer from a speaker. Storage devices Any hardware that stores information in a computer is called a Storage Device. Let’s have a look at some of the hardware storage devices: Hard Disk A hard disk is a data storage device. It is used for storing and recovering large volumes of data. CD / DVD It is a round disk with a shiny surface. It is used to store large amounts of data mostly games, videos, movies, songs etc. These can be of different types which are used for reading only, writing only or both. USB Pen Drive (Flash Drive) It is a handy storage device and connects to the computer via USB port. It can also be used to store or transfer data from one computer to another. 20 14-12-2017 18:24:04 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 26

Let Us Do 2: What do you call the objects shown in the picture? ____________________________________________________ Are they hardware or software? ____________________________________________________ The computer hardware mentioned above is controlled by a list of commands called Software. Let us know more about it. Software Software refers to the part of the computer which we cannot touch. It is the form of commands which make the computer work. The set of commands is called a program, and one or more programs is termed as software. Do You Know? “The games you play on the computer are software.” Let us take the example of a TV. The TV itself is a hardware. But the programs we watch on TV are software. There are two main types of software. System Software The system software makes a computer useful. It helps all parts of a computer to work together. The Operating System is the most important system software. It is the ÀUVWVRIWZDre loaded into computer memory. Some examples of system software are: Microsoft Windows MAC OS JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 27 21 14-12-2017 18:24:04

4 LET’S LEARN OPERATING SYSTEM Hi, Kids! I am back. Do you remember which part is called the heart of a computer? Yes, it is the Operating System. Let Us Start We already know about various parts of a computer. An operating system is the most important part that runs on a computer. Between the hardware and the application software lies the Operating System. Did you know that you and your computer speak different languages? It does not speak Spanish, Swedish, or Chinese; it speaks in ones and zeros. We can’t communicate directly with the computer. Here the Operating System comes in. It is a system software. In this lesson We will learn ‡ 2SHUDWLQJV\\VWHPDQGLWVW\\SHV ‡ 'LIIHUHQWSDUWVRIDGHVNWRS The Operating System is the program that lets you talk to the computer without knowing its language. It tells the computer how to do its work and run its functions. These days the Operating System is already loaded on the computer. Operating System tasks: ‡ $FFHSWVinputs from mouse or keyboard. ‡ 6HQGVoutputs to the display monitor and printer. 27 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 33 14-12-2017 18:24:04

Operating Systems use Graphical User Interface. It is pronounced “gooey,” with menus, icons, and task bars. A GUI helps us to use the mouse to point and click on icons or buttons on the screen. Different operating systems have different GUI. Let’s have a look at the different operating systems: Microsoft Windows Microsoft created Windows Figure 4.1 Windows Operating System operating system in 1985. Over the period, Microsoft kept updating and releasing many versions of Windows. As of September 2016, the most recent version of Windows is the Windows 10. Other recent releases are Windows 8 and Windows 7. Windows happens to be the most popular operating system. Do You Know? First version of Windows, Windows 1.0 was released in 1985, two years after the initial announcement made by Microsoft about their new OS”. 28 14-12-2017 18:24:04 JSNR_181310003-_BGM_CSGK-G3-Integrated Book-Computers+GK-FY_WK_Text.pdf 34

Mac OS X Figure 4.2 Mac Operating System Mac OS was created by $SSOH in 1984 as part of Macintosh operating systems. It is the second most widely used desktop operating system after Windows. Initially, it was named Mac OS X until 2012. In 2016, with the release of MacOS 10.12 Sierra, the name was changed from OS X to MacOS. Linux /LQX[ SURQRXQFHG /,11 ux) is a family of Open- source operating systems; It is unique among the most- used operating systems. Open source means the operating system is free and available to people for modifying. Figure 4.3 Linux Operating System Do You Know? 21-year-old Linus Torvalds created Linux in Finland in 1991.

Learning Windows Desktop Here we will learn about Microsoft Windows desktop. An operating system needs a way to communicate with the user. The way the OS interacts with a user is called the Interface. MS-Windows is the most popular GUI operating system. When we start the computer, the area we look at is called the Desktop. It acts as a work area. The desktop is usually different from one computer to another. Figure 4.4 Windows Desktop There are various parts in the Microsoft Windows desktop. Let’s have a look at the parts: Icons: From the upper left to the lower left side of the screen, there are small pictures or images called icons. These small images represent items such as My Computer, Recycle Bin, etc. Fun Fact We cannot give the same name to different icons. My Computer: It shows the stored information on the computer. It can also show us the location of that information. Recycle Bin: It is the dustbin of your computer.

In this lesson We will learn Dbout some more tools, the Select and Crop features available in Paint. Also, will learn to move and copy the portions of an image. When Paint opens, you will see an empty window; drawing and painting tools are located in the ribbon at the top of the window. The following illustration shows the different parts of the Paint window. Let’s have a quick look at the window [Figure 5.1]. Figure 5.1: Paint Window Working with More Tools Figure 5.2: Paint Ribbon The Ribbon in Paint [Figure 5.2] includes a handy collection of drawing tools.
