Sample Paper for Computer Architecture and Organisation will improve the efficiency and learning regarding computer organization and Architecture.Read this carefully.

Computer Organization Sample Paper

1. Compare the characteristics of SIMD and MIMD.

Ans  MIMD stands for multiple instruction,multiple data whereas SIMD stands for single instruction,multiple data.

sample questions on computer architecture

2. What is instruction format? Discuss different types of instruction formats.

Ans: The number and arrangement of fields in a computer instruction is called the instruction format.When the assembler processes an instruction, it converts the instruction from its mnemonic form to a standard machine-language (binary) format called an “instruction format”.  In the process of conversion, the assembler must determine the type of instruction, convert symbolic labels and explicit notation to a base/displacement format, determine lengths of certain operands, and parse any literals and constants.

3. Explain the stack-based architecture of a CPU with the help of a diagram.

Ans: A stack computer is programmed with a reverse polish notation instruction set.

4. What is memory hierarchy? Why do we need it?

Ans: A “memory hierarchy” in Computer storage distinguishes each level in the “hierarchy” by response time.

5. What is RAM? Explain 2D organisation of RAM.

Ans: RAM is basically Random Access Memory.

6. What is Cache? Discuss associative mapped cache organisation?

Ans: A CPU cache is a cache used by the CPU of a computer to reduce the average time to access memory.

7. Define addressing modes.Classify and explain with examples.

Ans: An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere.

8. Differentiate between Hardwired control and Microprogrammed Control.

Ans: A hardwired control unit has a processor that generates signals or instructions to be implemented in correct sequence.

9. Define stack with applications.Show how a stack can be implemented using auto-increment and auto-decrement addressing modes.

Ans: Stack is basically a last in first out data structure.

10. Write short notes on memory reference,CPU reference and I/O reference.

Ans: In computer science, a reference is a value that enables a program to indirectly access a particular datum, such as a variable  or a record.
