2 HANDLING THE MOUSE AND KEYBOARD Hey Gini, can you Sure Clicko, I do tell me what the remember! They are main parts of a computer are? Monitor, CPU and Keyboard. Let Us Start Gini forgot to mention one of the main parts of the computer. It is also called a pointing device. We can give input to the computer with the help of this device. Let Us Do 1: Can you remember the name of the device? Name and draw the device in the space below. 12 14-12-2017 16:51:53 JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 18

Yes, Clicko, Now I Gini, we will remember all the parts discuss the mouse of a computer. Look at the keyboard. It has so many keys and keys on the on it. What are all these keyboard here. keys used for? In this lesson We will know ‡ 'LIIHUHQWPRXVHDFWLRQV ‡ 7KHNH\\ERDUGDQGLWVNH\\V Using the Mouse The mouse is an Input device also known as a pointing device. It is used to point out the items present on the computer screen. A mouse is used to select and open programs using the pointer. When we move the mouse around, the arrow on the screen also moves around. The arrow is called the mouse pointer. The mouse is XVXDOO\\NHSWRQDÁDWVXUIDFHFDOOHGWKHmouse pad. Parts of a Mouse: Mouse pad A mouse has two buttons on the top. The button on the left-hand side is called the left button. The button on the right-hand side is called the right button. A scroll wheel is there in between two buttons. It helps us to move the cursor JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 19 13 14-12-2017 16:51:53

Fig. 2.2 Wireless Mouse Let Us Do 2: In the mouse given below, mark and colour the left button Blue and right button Green. Mouse Actions Pressing the button is called a Click. Clicking these buttons tells the Computer what to do. These are called actions. There are different types of mouse actions. Let’s learn them. 1. Left Button Action ‡ L eft Click: Click the left button once. This is used to select an activity after you point to it. ‡ Double-Click: Click the left button twice, quickly. This is used to open a document or program. 14 14-12-2017 16:51:53 JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 20

Right Button Action  ‡ Right-Click:&OLFNWKHULJKWEXWWRQRQFH'LVSOD\\VDOLVWRIFRPPDQGV 3. Scroll Wheel  ‡ Scroll: Moves up and down pages. Friends! We learned the different actions in the mouse. Now, let us read the purpose for which the keyboard is used into a computer. Keys on the Keyboard The Keyboard is used to type numbers, words and symbols on the computer. The keyboard is made of several small buttons called ‘keys’. A standard keyboard has 104 keys. Each key corresponds to a number or letter or some special function. The keyboard is connected to the CPU by a wire. Fig. 2.3 Standard Keyboard 15 JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 21 14-12-2017 16:51:53

Let Us Do 3: In the keyboard given below color the Letters of your favorite place you visited or you wish to visit. Then write few lines about it in the space given below. There are different types of keys on a keyboard. Let us now read ‡ 1XPEHUNH\\V about a few of ‡ $OSKDEHWNH\\V ‡ $UURZNH\\V these keys in ‡ 6SHFLDONH\\V detail. ‡ 6\\PERONH\\V 16 14-12-2017 16:51:53 JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 22

ALPHABET KEYS The alphabet or letter keys (Fig. 2.4) are used to write text on the computer. There are (A to Z) 26 letter keys in 3 rows. First row (Q, W, E, R, T, Y, U, I, O, P) 10 OHWWHUV6HFRQGURZ$6')*+-./ OHWWHUV7KLUGURZ=;&9%1 M) 7 letters. Fig. 2.4 Alphabet Keys Do You Know? The QWERTY keyboard was developed by Christopher Sholes in 1874. NUMERIC KEYS The number keys (Fig. 2.5) are also called numeric keys. There is a total of 10 QXPHULFNH\\V RQWKHNH\\ERDUG Two sets of numeric keys are there on the keyboard. The number keys on the right side of the keyboard are called as the Numeric Pad. To use the numeric pad we need to press the NUM LOCKRQÀUVW JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 23 17 14-12-2017 16:51:53

All the number keys have special symbols printed on them. These keys are used for other purposes as well. Fig. 2.5 Number Keys CURSOR CONTROL KEYS A cursor is a small blinking line on the monitor. It shows the position of the next letter or number to be entered. The cursor control keys (Fig. 2.6) are also called as the arrow keys. These keys are used to move the cursor up, down, left or right. Fig. 2.6 Cursor Control Keys CAPSLOCK KEY Pressing the Caps Lock key allows you to type in capital letters. Press the Caps Lock key once again to type in lower case letters. 18 14-12-2017 16:51:53 JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 24

A small green light on the keyboard indicates the status (light on – Capital letters, light off – lower case letters). SHIFT KEY Shift Key is used with the other keys for different purposes. Pressing and holding the shift key along with a letter key will type that letter in the capital even when Caps Lock is turned off. For example: gives ‘A’ (when the Caps Lock is off). Also, gives ‘a’ (when the Caps Lock is on). SYMBOL KEYS Symbol keys have special signs and symbols. These are present to the right of the letter keys such as: /, “, :, <, > etc. The special characters are also placed over the numbers on the Number keys such as: !, @, #, $, %, * etc. We can use these as Symbol keys by pressing the Shift key along with the Number key. Fig. 2.7 Signs and symbols Fig. 2.8 Special Characters above numbers SPECIAL KEYS Special keys are required to perform some special functions. Some of the special keys work in combination with other keys. JSNR_181310002-_BGM_CSGK-G2-Integrated Book-Computers+GK-FY_WK_Text.pdf 25 19 14-12-2017 16:51:53

Keyboard The keyboard is used for entering data into the computer system. It can type words, numbers and symbols. The keyboard is probably the most used input device. Mouse The mouse is a most popular pointing device. It is used to draw pictures and select objects on the computer. %XWLWFDQQRWEHXVHGWRHQWHUWH[WLQWRWKHFRPSXWHU Scanner The Scanner is used to input photographs or pages of text directly into the computer. Joystick A joystick is an input device commonly used to control video games. It is also a pointing device. Microphone The microphone or mike allows computer users to input audio into their computers. It can be used for various applications like adding sound to a multimedia presentation or for mixing music. Webcam A web camera takes pictures and puts it into the computer. These are the most commonly used devices. See below a few more examples of Input devices.

Output Devices 'HYLFHVWKDWWDNHDQGUHFHLYHLQIRUPDWLRQ287RIWKHFRPSXWHU are called Output devices. The output from the computer may be printouts from the printer, sounds on the speaker, or images on the monitor.
