3. Today’s computer giant IBM was earlier known by a different name which was changes inn 1924. What was that name?
b. Tabulator Machine Co.
[Dr. Herman Hollerieth designed Tabulating Machine to solve the problem of US census of 1880. He formed Tabulating Machine Company to produce and sell these machines. Later in 1924 he joined with some other firms and company converted into IBM. ]
4. The first electronic general purpose digital computer built by Mauchly and Eckert called ENIAC did not work on the stored program principle. How many numbers could it store in its internal memory?
b. 20
[Babage too thought of designing Analytical Engine that could process upto 20 digits, could not be finished due to the lack of engineering advancement and funding. This milestone had achieved by ENIAC. It used Decimal numbering system]
5. The digital computer was developed primarily in
c. USA
6. The subject of cybernetics deals with the science of
b. Control and communications
7. Who is credited with the idea of using punch cards to control patterns in a weaving machine?
d. Jacquard
[Joseph Jacquard was a textile manufacturer. He developed a weaving loom that used punched cards to automate weaving patterns in clothes. This idea of using punched cards to control of machine was later used by Charles Babbage. Herman Hollerieth too used them for his Tabulating Machine]
8. Most of the inexpensive personal computer do not have any disk or diskette drive. What is the name of such computers?
a. Home computers
9. Which of the following require large computers memory?
d. All of the above
[Imaging, Graphics, Voice, Video are some application areas of computers that require large amount of memory and processing capability ]
10. A term associated with the comparison of processing speeds of different computer system is:
c. MIPS
[MIPS stands for Millions of Instructions Per Second that indicate the speed of processing of any computer system]
