JOHN VON NEUMAN gave the concept of stored program. COMPUTER GENERATIONS:- 1st GENERATION:- It started in 1950 with appearance of UNIVAC-1. in this generation vacuum tubes were used, and there memory were made of thin tubes of liquid mercury and magnetic drums. computer uses the stored program concept in this period. the idea was to store the program in separate memory but since the vacuum tubes were very costly so it discouraged the manufacturers to use it and instead they electrostatic memories. the speed of this age of computers was very slow as compared today and size was very large(about two rooms) also it required large cooling towers as there was lot of heat produced by vacuum tubes. the cost was so high that it was almost impossible for general people to afford it. 2nd GENERATION:- the greatest problem of the computers was such a big size and slow processing. a revolutionary technology known as transistor was being introduced in this era. transistor replaced the vacuum tubes and it used ferrite core as memory. the size was considerably reduced but was still about(half a room). generally germanium semiconductor was used which was more reliable and faster.in this period HIGH LEVEL LANGUAGE, COBOL, FORTRAN AND ALGOL were developed. greater reliability and faster processing led to development of the OPERATING SYSTEM. wanna know more give a visit at http://impcompfacts.blogspot.com post reviews and comments there we value it Computer Hardware Computer Component Computer Electronics Computer Retailers Computer Operating System Find Operating System articles at the UK's leading IT resource!
