CPU (Central Processing Unit)

CPU, computer, Desktop, Niraj Tutorials
The part of computer that executes programs. In structures is known as the processer or the Central Processing Unit (CPU). In a computer the CPU is on a single electronic component in the system cabinet.
  • CPU is the brain of computer.
  • It perform all type of data processing operations.
  • It control the operation of all parts in the computer.

The CPU has three parts.

Parts of Computer, CPU, Niraj Tutorials

  • Control Unit (CU)
  • Arithmetic Logic Unit (ALU)
  • Memory Unit (MU)

    Control Unit (CU)

    Control Unit, CU, Niraj Tutorials, Parts of CPU

    The control unit tells the rest of computer how to carry out programs introduction. It direct the movement of single electronics signals between Memory and ALU.
    • It manages and co-ordinates from the memory.
    • It communicate with input devices and output devices for transfer of data or results from storage.
    • Control unit does not process or store data and responsible for controlling the transfer of data or information.

    Arithmetic Logic Unit (ALU)

    Arithmatic Logic Unit, ALU, Parts of CPU

    This unit has two sub-sections.

    • Arithmetic Section
    • Logic Section

    Arithmetic Section

         Arithmetic operations are the mathematical operations consist of Addition, Subtraction, Multiplication and Division.

    Logic Section

          Logical operation consist of comparison that is two pieces of data are compare to see on Equal to, Less than, Greater than and the other.

    Floppy Disk Floppy disk is slower to access than hard disk. Floppy disk has low storage capacity, if the size of file increases than decreases the capacity of floppy disk. Hard Disk A Hard Disk is a storage medium. This drive is made up of a series of circular disk called platters arranged. A Hard Disk drive are made of non-magnetic material. A Hard Disk composed of numerous discs of metered sensitive to magnetic field. It has magnetic technology. Optical Disk An Optical Disk is input and output device. These devices use lesser technology to record data and information. It has a large storage capacity of the Gigabyte (GB). Magnetic Tape Magnetic Tape is a storage medium of secondary memory. They fit up to more than 4GB (Gigabyte). Pen Drive A Pen Drive is a portable memory devices. It is used to solid state memory rather t

    The language translator is a program that converts programming languages into another programming language. Language translator is also called language processor. A program written in any high-level programming languages is known as the source code, to convert the source code into machine code is known as object code. There are three types of language translator. Assembler Compiler Interpreter Assembler An assembler is a program written in machine level language whose function to translate the assembly language code into machine language code. It is a low level programming language where we place of machine codes. Advantage Assembler is very fast translating assembly language to machine code as one by one relationship. Efficiency in execution just like machine level language. Disadvantage Assembly language is difficul

    The period of the third generation was from 1965-1971. In this generation was used of IC (Integrated Circuits). IC reduced the price, size , use of electricity, etc. Third generation computers were used Keyboard, Mouse, and also used the operation system to improved a new level and high speed. Characteristics of the third generation computer Use of IC (Integrated Circuits) instead of transistors Use of magnetic storage device Use of mini-computers Use of monitor, keyboard, and line printers Use high-level programming languages Less expensive maintenance cost Less expensive than second generation Improved faster operations and more dependable Small size than second generation computer Some computers of third generation IBM 360 series IBM 370 IBM 168 TDC 316 Honeywell 6000 series PDP (Personal Data Processor)
