Study Notes Computer Awareness Quick Revision Notes
The earlier computers, which were massive in size, were based on vacuum tubes. 2. Early computing machines, like the ENIAC, were actually meant to assist the armed forces. 3. The printers in pre-1950s were punch cards. 4. An improvement on the ENIAC, which pioneered 'stored program', was made possible with the help of the mathematician John von Neumann. 5. Before the 1950s, computers were mostly owned by universities and research labs. 6. The B-programming language was developed by Ken Thompson. 7. Famous people, associated with the ENIAC, EDVAC, UNIVAC computers are Eckert & Mauchly.
8. The 1st commercially produced and sold computer (1951) was UNIVAC. 9. IBM was provided software for PCs by Microsoft. 10. Time-sharing, teletyping, were associated with mainframe computers. 11. The transformation from heavy computers to PCs was made possible using microprocessors. 12. The first microprocessor was developed in 1971 by Intel. 13. The term 'micro' (extremely small) denotes 10-6m. 14. The Harvard student, who chose to write computer programs and dropped studies was Bill Gates.
15. A pentium 4 (P-4) employs roughly 40 million transistors. 16. Mark-1, Apple-1, and collossus were initial desktop computers.
17. Binary digits are briefed as bit. 18. A collection of bits is called byte. 19. C++, is a computer language. 20. The process of eliminating programming faults is called debugging. 21. Starting up on operating system is called booting. 22. A program used to browse the web is called browser. 23. An error in software designing which can even cause a computer to crash is called bug. 24. Click and double-click are achieved using the mouse. 25. Java, C, ForTran, Pascal and BASIC are computer programming languages.
26. The device which sends computer data using a phone line is called MODEM. 27. 'Worm' and 'virus' are actually programs. 28. A 'file' is a unit of
