COMPUTER ORGANIZATION AND
ARCHITECTURE UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
COMPLETE STUDY GUIDE FULL SOLUTION
●● What are the main objectives of studying computer organization and
architecture?
Answer: To design better programs, optimize program behavior,
evaluate computer system performance, and understand time, space, and
price tradeoffs.
●● What does the Principle of Equivalence of Hardware and Software
state?
Answer: Any task done by software can also be done using hardware,
and vice versa, assuming speed is not a concern.
●● What are the three basic components of a computer?
Answer: A processor to interpret and execute programs, a memory to
store data and programs, and a mechanism for transferring data to and
from the outside world.
●● What does 'Kilo-' represent in terms of measurement?
Answer: Kilo- (K) represents 1 thousand, or 10^3 and 2^10.
, ●● What is the definition of a Hertz?
Answer: A Hertz is a measure of frequency, defined as clock cycles per
second.
●● How is processor speed typically measured?
Answer: Processor speed is measured in MHz (megahertz) or GHz
(gigahertz).
●● What is a byte?
Answer: A byte is a unit of storage, with 1KB equal to 2^10 bytes.
●● What is the difference between RAM and cache memory?
Answer: RAM (random access memory) is used for temporary storage
of data and programs, while cache memory is a smaller, faster type of
memory that stores frequently accessed data.
●● What does 'millisecond' measure?
Answer: A millisecond is 1 thousandth of a second.
●● What is the significance of cycle time in relation to clock frequency?
Answer: Cycle time is the reciprocal of clock frequency; for example, a
bus operating at 133MHz has a cycle time of 7.52 nanoseconds.
