Parts of a Computer:

  • The computer is composed of two parts:
  • Hardware
  • Software
  • Hardware:
  • All physical components of computer, which can be touched, measured, have weight and occupy space, are collectively called computer hardware viz;
  • Keyboard
  • Mouse
  • Joy stick
  • Scanners
  • Monitor
  • Printer
  • Central Processing unit etc.

Software:

  • Software can be defined as a set of instructions or codes written in a defined manner. In other words software’s are prewritten programs, which control the operations of computer.
  • OR
  • All programs and data stored on floppy disk, Hard disk, CD-ROM are collectively called software’s. Examples are;
    • DOS
    • Window
    • UNIX
    • XENIX
    • Linus
    • Java
    • MS Office
  • Devices OR Components of a Computer:
  • The computer is a combination of many parts, each of which performs specific task independently. The major devices of a computer are as under.
  • Input Devices
  • The input devices are those devices which send data or information to the Central Processing Unit. The main input devices are:
    • KEYBORD: It is used to enter text. It contains alphabetic, numeric and other keys for entering data.
    • MOUSE: It is a pointing device. It controls the pointer on the screen.
    • MICROPHON: It is used to enter voice into the computer.
    • SCANNER: It reads printed text and graphics and then translates the result into digital form.
    • DIGITAL CAMERA: It is used to take photos.
    • PC CAMERA: It is used to create movie and to take photos on the computer.
  • OUT PUT DEVICES:
  • A hardware component used to display information to the user output device.
    • MONITER: It is used to display text, graphics and video output.
    • PRINTER: It is used to display printed output on paper.
    • SPEAKER: It is used to hear sound to hear sound music and voice outputs.
  • STORAGE DEVICE:
  • The hardware components used to store data, instructions and information permanently are called storage devices. For example floppy disk drive, zip drive, hard disk drive, CD-ROM drives etc.
  • COMMUNICATION DEVICES:
  • It is used to communicate and exchange data, instructions and information with other computers. For example Modem.

UNITS OF CPU:

  • UNITS OF CPU:
    • ALU (ARTHMETIC AND LOGICAL UNIT)
  • ALU is a part of CPU. Actual execution of instructions takes place in this part. All arithmetic and logical operations are performed in ALU. It consists of two units:
    • Arithmetic Unit
  • It performs basic arithmetic functions such as addition, subtraction, division.
    • Logical Unit
  • It performs logical operations like comparing two data items to find which data item is greater than, equal to, or less than the other.
    • CONTROL UNIT
  • It acts like a supervisor of the computer. It does not execute program instruction by itself. It controls and coordinates all activities of computer system.
    • Memory Unit (MU)
  • It is responsible for storage of data and information. The memory unit consists of two types of memory which are RAM and ROM.
  • Some Important Definitions and Short Notes:
  • RAM:
  • RAM stands for random access memory. It is that part of CPU where temporary information is stored.
  • Byte:
  • A group of 8 bits is called a byte.
  • Icons:
  • Pictorial objects on the desktop or screen are called Icons.
  • Mouse:
  • It is an input device, normally called a “Pointing device”. This device is used for pointing anything on monitor through a blinking cursor.
  • Software:
  • A set of instructions or codes written in a defined manner or prewritten programs which control the operations of computer.
  • Control Unit:
  • A unit of CPU which is responsible for all automatic operations carried out by the digital computers is called CU. The CU directs and coordinates all activities of a computer.
  • LAN:
  • LAN stands for local area network. It is privately owned communication network that serves users within a confirmed geographical area. The range is usually within a mile-perhaps one office, one building or a group of buildings.
  • WAN:
  • It stands for wide area network. It is a communication network that covers a wide geographical area. The range is usually a state or a country. Examples are Telnet, Unlined etc.
  • Modem:
  • Modem is abbreviation of Modulate-de-Modulate. Modulation is a process that converts digital signals into Analog form and Demodulation is a process that converts Analog signals into digital form. The device which performs modulation and demodulation is called a MODEM. In simple words it is a device that converts the digital signals into Analog and then back from Analog to digital form.
  • ALU:
  • A unit of CPU that performs arithmetic and logical operations is called ALU.
  • Register:
  • Registers are high-speed staging areas that temporarily store data during processing and provide working areas for computation.
  • Registers are contained in control unit and arithmetic Logic Unit. Following are the major types of registers:
    • Address Register
    • Instructions Register
    • Storage Register
    • Accumulator Register
  • Soft Copy:
  • It displays the data on screen of monitor. It can be carried in a floppy disk. A change can be made in a soft copy.
  • Hard Copy:
  • The data is printed on paper card etc. with the help of printer. It cannot be carried in a floppy disk. No change can be made in hard copy.
  • Half byte = 1nibble = 4 bits
  • Bit means Binary Digit
  • 1 byte = 8 bits
  • 1 megabyte = 1048576 bytes
