  16. 16. Mouse - is a pointing device that detects two- dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface.
  17. 17. Touch Screen
  18. 18. Touch Screen -is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with a special stylus/pen and- or one or more fingers. Some touchscreens use an ordinary or specially coated gloves to work while others use a special stylus/pen only. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size).
  19. 19. Touch Screen -is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with a special stylus/pen and- or one or more fingers. Some touchscreens use an ordinary or specially coated gloves to work while others use a special stylus/pen only. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size).

  27. 27. Scanners -A scanner is an input device that scans documents such as photographs and pages of text. When a document is scanned, it is converted into a digital format. This creates an electronic version of the document that can be viewed and edited on a computer. Most scanners are flatbed devices, which means they have a flat scanning surface. This is ideal for photographs, magazines, and various documents.

  46. 46. Control Unit
  47. 47. Control Unit is a component of a computer's central processing unit (CPU) which directs operation of the processor. It controls communication and co-ordination between input/output devices. It reads and interprets instructions and determines the sequence for processing the data.
  48. 48. Arithmetic logic unit (ALU)
  49. 49. Arithmetic logic unit (ALU) is a digital circuit that performs integer arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) accommodate very powerful and very complex ALUs; a single component may contain a number of ALUs.
  50. 50. Computer data storage,
  51. 51. Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but larger and cheaper options farther away.

  61. 61. Video Display Units
  62. 62. Video Display Units VDU displays images generated by a computer or other electronic device. The term VDU is often used synonymously with “monitor," but it can also refer to another type of display, such as a digital projector. Visual display units may be peripheral devices or may be integrated with the other components. For example, the Apple iMac uses an all-in-one design, in which the screen and computer are built into a single unit.
  63. 63. Video Display Units VDU displays images generated by a computer or other electronic device. The term VDU is often used synonymously with “monitor," but it can also refer to another type of display, such as a digital projector. Visual display units may be peripheral devices or may be integrated with the other components. For example, the Apple iMac uses an all-in-one design, in which the screen and computer are built into a single unit.
  64. 64. Audio Response Unit
  65. 65. Audio Response Unit A device that provides synthesized voice responses to dual-tone multifrequency signaling input by processing calls based on (a) the call-originator input, (b) information received from a host data base, and (c) information in the incoming call, such as the time of day.
  66. 66. Audio Response Unit A device that provides synthesized voice responses to dual-tone multifrequency signaling input by processing calls based on (a) the call-originator input, (b) information received from a host data base, and (c) information in the incoming call, such as the time of day.
  67. 67. Printers
  68. 68. Printers is a peripheral which makes a persistent human-readable representation of graphics or text on paper or similar physical media.

  79. 79. Primary Storage Function Unit
  80. 80. Primary Storage Function Unit (main memory/hard disks) Primary storage, also known as main storage or memory is the main area in a computer in which data is stored for quick access by the computer's processor. On today's smaller computers, especially personal computers and workstations, the term random access memory (RAM) - or just memory - is used instead of primary or main storage, and the hard disk, diskette, CD, and DVD collectively describe secondary storage or auxiliary storage.
  81. 81. Secondary Storage Devices
  82. 82. Secondary Storage Devices (Magnetic disk tape units optical disks) Secondary storage technology refers to storage devices and storage media that are not always directly accessible by a computer. This differs from primary storage technology, such as an internal hard drive, which is constantly available.
