  2. 2. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy Subject: Information Technology Topic: Input Devices Grade: 7s General Objectives: At the end of the lesson students should be able to: I. Develop and understanding of input devices. Specific Objectives: Students should be able to; I. II. Correctly define the term input devices without the aid of a teacher Correctly identify at least three (3) input devices from each category without the help of the teacher. III. Properly distinguish between at least five (5) input devices without the aid of the teacher.
  3. 3. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy What is an Input Devices? Any hardware component that allows you to enter data, programs, commands, and user responses into a computer Input devices can be classified in two (2) categories: Manual input devices are those devices that require one to physically operate them in some manner in order to input data. Automated input device are methods of capturing and entering data directly to the computer without the intervention of the user MANUAL INPUT DEVICES MOUSE The mouse is an input device designed to manipulate objects on the computer screen.
  4. 4. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy TYPES OF MOUSE A Mechanical mouse has a rubber ball on its underside to detect movement of the mouse. An optical mouse uses devices that emit and sense light to detect the mouse's movement A cordless mouse transmits data using wireless technology such as radio waves or infrared light waves TRACK BALL A trackball is a pointing device consisting of a ball housed in aarrival of the touchpad, on portable computers, where there may be no desk space on which to use a mouse. Some clip onto the side of the keyboard and have integral buttons which have the same function as mouse buttons.
  5. 5. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy KEYBOARD A keyboard contains keys that allow a user to enter data and instructions into the computer. SCANNER A scanner is a light-sensing input device that converts printed text & graphics into a digital form that can be processed by the computer.

  7. 7. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy AUTOMATED INPUT DEVICES BARCODE READER A barcode reader is a computer peripheral for reading barcodes printed on various surfaces. Magnetic Ink Character Reader (MICR) This enables special characters printed in magnetic ink to be read and input rapidly to a computer Optical Mark Reader The is a device that "reads" pencil marks on compatible scan forms such as surveys or test answer forms.
  8. 8. INFORMATION TECHNOLOGY INPUT DEVICES Shenel McCarthy Optical Character Recognition This is computer software designed to translate images of handwritten or typewritten text into machine-editable text, or to translate pictures of characters into a standard encoding scheme representing them
