CS6303   COMPUTER ARCHITECTURE  QUESTION BANK

PART-A- (TWO MARK QUESTIONS AND ANSWERS)

UNIT-I OVERVIEW & INSTRUCTIONS

1.Define Computer Architecture.

•  It is concerned with the structure and behavior of the computer.
•  It includes the information formats, the instruction set and techniques for addressing memory.
2.Define Computer Organization.
•  It describes the function and design of the various units of digital computer that store and process information.
•  It refers to the operational units and their interconnections that realize the architectural specifications.
3.What are the components of a Computer.
•  Input unit
•  Memory unit
•  Arithmetic and Logic Unit
•  Output unit
•  Control unit

5. What is Execution time/Response time?
Response time also called execution time. The total time required for the computer to complete a task, including disk accesses, memory accesses, I/O activities, operating system overhead, CPU execution time, and so on.

7.What is clock cycle and clock period?
clock cycle :The time for one clock period, usually of the processor clock, which runs at a constant rate.
clock period :The length of each clock cycle.
6. Define CPI
The term Clock Cycles Per Instruction Which is the average number of clock cycles each instruction takes to execute, is often abbreviated as CPI.
7.State and explain the performance equation?
N denotes number of machine Instructions, Suppose that the average number of basic steps needed to execute one machine instruction is S, where each basic step is completed in one clock cycle. If the clock cycle rate is R cycles per second, the processor time is given by
T = (N x S) / R This is often referred to as the basic performance equation.
8. Define MIPS .
MIPS:One alternative to time as the metric is MIPS(Million Instruction Per Second)
MIPS=Instruction count/(Execution time x1000000).This MIPS measurement is also called Native MIPS to distinguish it from some alternative definitions of MIPS.
