Computer History

HOME COMPUTER GENERATIONS

1st GENERATION: - It started in 1950 with appearance of UNIVAC-1. in this generation vacuum cleaner tubes were utilized, as well as there memory were made of slim tubes of fluid mercury as well as magnetic drums. laptop uses the saved program concept in this period. the idea was to store the plan in separate memory however considering that the vacuum cleaner tubes were really costly so it discouraged the suppliers to use it and also as an alternative they electrostatic memories. the performance of this age of home computers was very lagging as compared today and also size was very large (about 2 areas) also it required large cooling towers as there was lot of warmth created by vacuum tubes. the cost was so higher that it was just about impossible for general people to afford it.

2nd GENERATION: - the greatest issue of the pcs was such a big size and slow handling. a revolutionary modern technology known as transistor was being offered in this era. transistor switched out the vacuum tubes and it used ferrite center as memory. the dimension was significantly lessened yet was still concerning (half a room). normally germanium semiconductor was used which was more trusted as well as quicker. in this period HIGH DEGREE TERMINOLOGY, COBOL, FORTRAN AND ALSO ALGOL were created. higher stability and faster processing triggered progression of the OPERATING SYSTEM.

Long back regarding 4ooB. c first every computing tool was developed which could add and also take off. graduaklly afterwards there was usefulness of a computing instrument. pascal very first pc came in 1642and other analyst loike napiers as well as leibnitz done considerable job in this field which eventually caused provide day laptop. MARK-1 was the initial modern-day laptop. British math wizzard AUGUSTA ADA BYRON was the very first ever before developer. BASIC was launched in 1965. IBM computer was introduced in 1981. Visual computer system "MAC" came in 1984 and microsoft was introduced in 1985. windows 3.1 become most well-liked in 1992 bthe initial basic pc was ENIAC (ELECTRONIC NUMERICAL INTEGRATOR AND ALSO CALCULATOR). JOHN VON NEUMAN gave the idea of stored show.
