Descriptive Type Questions
Answer the following:
- Write any two limitations of the first-generation computers.
Following were the two limitations of the first-generation computers:
a. Their operating speed was quite low.
b. Their power consumption was very high. - Give full forms of ENIAC and UNIVAC.
ENIAC – Electronic Numerical Integrator and Computer.
UNIVAC – Universal Automatic Computer. - Mention any two features of the second-generation computers.
Following were the two features of the second-generation computers:
a. Transistors were used as the main component.
b. They were more reliable than the first-generation computers. - Give two examples of the fourth-generation computers.
IBM PC and Apple Macintosh are the two examples of the fourth-generation computers. - What are microprocessors? How have they benefited modern computers?
Microprocessors are a type of VLSIC (Very Large Scale Integrated Circuits), which contain all the components of the CPU on a single chip.
Microprocessors have benefited modern computers by reducing their size and increasing their efficiency.
