The development of computers goes back a long time ago and very interesting and very important for understanding the functioning of the computer. Long back on 4ooB. c First, all designed PCs tool that can add and subtract. graduaklly later, meaning of a computing tool. pascal first computer came 1642and other scientists Loike Napier and Leibnitz done considerable work in this area, which eventually present day computers. MARK-1 was the first modern computer. British mathematician Augusta Ada Byron was the first programmer. BASIC was introduced 1965th IBM PC was in 1981. The first graphical computer “MAC” came in 1984, and Microsoft was introduced in 1985. 3 windows. 1 acquired bthe most popular in 1992, first general computer was ENIAC (Electronic Numerical Integrator and Calculator). John von Neumann invented the concept of the stored program. COMPUTER GENERATIONS: – 1. Generation: – It started in 1950 with the publication of the UNIVAC-1. used in this generation, vacuum tubes were, and memory was of thin tubes of liquid mercury and magnetic drums. Computer used the stored program concept in this period. The idea was to put the program in separate memory, but since the tubes were very expensive, so that manufacturers use in order to discourage them and instead static memories. The speed of this age of computers was very slow compared with today, and size was very large (more than two rooms), they also have huge cooling towers required as much heat was produced by vacuum tubes. the costs are so high that it was almost impossible to provide for the general population. 2. Generation – the biggest problem the computer was such a large size and slow processing. a revolutionary technology, known as the transistor was introduced at this time. Transistor replaced the vacuum tubes and used as a ferrite core memory. size greatly reduced) but still above (one half the room. Germanium-semiconductor-rule was used that was more reliable and faster. developed in this period, high-level language, COBOL, FORTRAN and ALGOL were. higher reliability and faster processing of the development of the operating system run. want to know, give more, a visit to http://impcompfacts. blogspot. com post ratings and comments because we value it Computer Hardware Computer Components Computer Electronics Computer Trading Computer Operating System Find articles in leading operating IT resources in the United Kingdom!
