history
of computer in Nepal
the fist computer
brought in Nepal was IBM
1401 which was brought by the government in lease for the population census of
1972(2028 B. s) later, in 1975 (2031BS) yantrik Sarinikaran Kendra (Electornic
Data processing center) was established which was later called as national
Computer Center (NNC) . Again , for the population census of 2038 BS ICL 2050/10 computer center brought in Nepal
by the aid of UNDP. After 2039 B.s microcomputers Like, apple vector, sires
were introduced in the capital . from that time computer have been used in
different government sectors like, banking, agriculture, universities etc. Now
there are thousands of computer institute providing computer education,
assembling , maintenance etc. throughout the kingdom of Nepal.
Computer Generation
1.First Generation (1943-1958)
- vacuum
tube media.
-Mark -l
, (Pro. haword Akin)
1937(
L=51feet, B= 8 feet
, H= 7 feet, W= 32 ton
Mark -I = 18000 vacum tubes. 7 lakhs
50000 parts.
Mark - I , ENTAC, EDVAC.
2. Second Generation (1959-1964)
-
Transistor media (1949)
- 1000
vacuum tube = 1 transistor
- IBM 650, Univac - I , IBM
1400 series, 1600 series,
- Mili second = 1/1000Th
3. Third Generation (1965-1974)
- IC (
integrated circuit ) 1960
- More
than two program can be run.
- Micro second = 1/ 1000000th
4. Fourth Generation (1975- 1990)
- Micro
chips (processor)
- Intel
4004, Microprocessor (1971)
- Apple, IBM,
Dell, e tc.
- Nano
second time out = 1/1000000000th
5. fifth Generation (1990- Now)
-Bio
chip
- super
conductor
- Bio
chip is 1 cored powerful than micro chip.
- Pico second = 1/ 1000000000000th
time out
