Document Summary

We try to achieve a first understanding of computer science by: evolution, classification, applications. Arithmetic, logic, sorting, selecting, input, output, processing, hardware, software. 1st generation: time period: 1951 1959, size: very large system, technology: vacuum tubes, processing: very slow, characterized by, magnetic drums, magnetic tapes, difficult to program, used machine. Language: examples: abacus, pascaline, analytical engine (father of modern computer), ibm mark- 2nd generation: time period: 1959-1963, size: smaller, technology: transistors, processing: faster, characterized by, magnetic cores, magnetic disk, used high level language, easier to program. Ics (integrated circuits) incorporated many transistors & electronic circuits on a single chip: size: small as compared to 2nd generation computers, processing: faster than 2nd generation computers, characterized by, minicomputers accessible by multiple users from remote terminals. 4th generation: time period: 1975-today, technology: vlsi (very large scale integration) incorporated many millions of transistors. 5th generation: time period: future technology, technology: ai (artificial intelligence)
