Fourth Generation Of Computer
The period of the fourth generation of computer was from 1971-1980. In this generation used LSI and VLSI (Very Large Scale Integration) circuits. VLSI circuits having at list 5000 transistors and other circuits elements. The microprocessor was used in fourth generation computers.

Fourth generation computers were small in size, reliable, compact and more powerful. In this generation were used real time networks, time sharing and distributed operating system. All the high level programming languages like C, C++, DBASE, etc., were developed in fourth generation computer.

Characteristics of fourth generation

  • Microprocessor based system that use VLSI circuits
  • Very small in size
  • Less power consumption
  • Faster, reliable and cost-effective
  • Use of VLSI (Very large Scale Integration
  • No AC required

Some computers of fourth generation are following:

  • PDP 11
  • DEC 10
  • STAR 1000
  • CRAY-1
  • CRAY-X-MP
  • IBM 3033
  • Sharp PC-1211

The period of the second generation was from 1955-1965. The transistors were invented in 1947, which was used in second generation computers. By using transistors computer was becoming less expensive, more relieve, less power consume than generation computer. In this generation was used as assembly language and high-level programming languages such as COBOL and Fortran and used batch processing. Characteristics of the second generation computer Use of the transistors Faster than the first generation computer High speed input/output devices Reduced size Magnetic memory and magnetic storage disk Use of high-level programming languages such as Fortran and COBOL Solution to heat generation Improvement of speed and reliability Communication by using telephone line Some computers of second generation IBM 1400 IBM 1620 IBM 7094 series UNIVAC 1108

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)

MICR (Magnetic Ink Character Reader) is a character recognition system. It is an input device. These devices are mainly used in banking, industry to read the bank's code number and cheques number. An MICR can identify character printed on the cheques with a special type of ink that contents particles of magnetic material, it passes through a machine and than translates the magnetic information into characters. An MICR provides a secure, high-speed method of scanning and processing data and information. Card Reader A card reader is a data input device. It is use to transfer data from a card-shaped storage medium to computer. A memory card reader is a input device used for communication with a memory card or a smart card. A magnetic card reader is a device. These device uses to read magnetic stripe card, such as debit cards and credit
