Computer History

 

First Generation Computers

Characteristics are:

Circuits employing vacuum tubes (Vacuum Tube)
The program will certainly single be developed utilizing machine language (Machine Language)
Using maintained process because of the main memory is a magnetic core storage
Using external storage magnetic tape jual running text and also magnetic disk
The physical size of an large computer, requiring an spacious room
Heat quickly, and so the necessary cooling
The system can be rapidly enough
Small savings
Require a good large electric power
The main orientation inside institution applications
1946: ENIAC (Electronical Numerical Integrator and also Calculator), will be used to calculate ones target of your bomb, Dr. John W. Mauchly, Moore School of Engineering electronical Pensylcania University
1947: Harvard Mark II (Development of any previous generation)
1948: IBM Selective series Electronic Calculator]
1949: EDSAC (Electronic Delayed Storage Automatic Computer, the first computer Yanga using stored program, John Van Neumann)
1949: ACE (Automatic Calculating Engine) large-size electronic digital computer at the primary Inggir, Alan M Turing, National Physical Laboratory London
1950: SEC (Electronic Computation of Birkbeck College, University involving London)
1951: LEO (Lyon Electronic Office), your current first commercial computer english
1951: UNIVAC i (Universal Automatic Computer), your current very first to utilize magnetic tape being a medium with regard to input and output, Sperry Rand Corporation
1952: EDVAC (Electronic Discrete Variable Automatic Computer) am first put towards full method held on the US
1952: Whirlind I, the primary computer to work with magnetic core memory, Dr. Jay W. Forrrester, MIT
1953: IBM 701, ones initial commercial-sized computer, your own 1st generation of a many popular yanag
1956: 305 RAMAC (Random entry technique regarding Accounting as well as Control), your first computer make use of external storage throughout random access
1959: IBM 705, was designed to replace your IBM 701
Second Generation Computers

Cirnya features:
The circuit uses transistors (developed from Bell Laboratorories through John Barden, William Shockley, in addition to Walter Brattain 1947)
Programs can be formulated in high-level languages ??(High Level Language) ex: FORTRAN
The main memory capacity is actually large enough with the development of magnetic core storage
Using external storage involving magnetic tape along with magnetic disk-shaped removable disk
Have ones ability to process true day along with time-sharing
The computer’s physical size can be smaller in comparison with ones first generation
Operation method will be faster
Requires less power
Orientation will be not sole business applications tapu furthermore towards form technique
1959: PDP 1 is actually intended through DEC (Digital products Corporation), Ken & Stan Olsen and also Harlan Anderson
1963: PDP 5 primary commercial minicomputer, but That additionally may be the PDP 8
Computers usually are all widely taken in the second generation are your IBM 401 regarding company applications, IBM 1602 along with IBM 7091 with regard to application techniques

Third Generation Computers

Characteristics:
Component circuits utilizing IC (Integrated Circuits)
Enhancements
Faster along with added precise
Greater computer memory capacity
Using external penympanan which might be random acces
More efficient power usage
Allows to help work multiple processing
The development of a tool input and also output making use of graphic Display Terminal
Prices tend to be receiving cheaper
Data communication capabilities between computers
1964: IBM S / 360, ones initial third-generation computers taken regarding business applications and techniques
1969: NOVA was produced via info General Corporation, ones very first 16-bit minicomputer

Fourth Generation Computers

Characteristics:
Pengugunaan Large Scale Integration (LSI) / Bipolar Large Scale Integration, namely compaction thousands involving ICs in to an CHIP
Developed having a microcomputer in microprocessor and semiconductor for the form of chips intended for computer memory
1970: IBM 370, your primary fourth-generation computer
1971: Intel business successfully developed the 4004 microprocessor chip
1974: Micro Instrumentation along with Telemetry Systems company manufactures Altair microcomputer
1975: Cray 1, ones initial super computer
1977: ARCNET, your own 1st LAN, Datapoint Corporation
1977: Apole II, Individual Computer First
1981: IBM PC / AC (Advanced Technology)
1997: Pentium II
1998: AMD K6 3D

Fifth Generation Computer

Characteristic features :
VLSI development
Development Josephson Junction
