Q1. Explain the role of addressing modes in computer architecture. 10 

Ans 1.

Role of Addressing Modes in Computer Architecture

Addressing Modes

Addressing modes in computer architecture define how the operand of an instruction is accessed. These modes are essential because they provide flexibility and efficiency in instruction execution. In simple terms, addressing modes determine where the data resides and how it can be retrieved or manipulated.

The CPU uses addressing modes to access data located in registers, memory locations, or directly within the instruction itself. By offering different methods to refer to data, addressing modes enable complex data

Q2. How does a microprogrammed control unit differ from a hardwired control unit?

Ans 2.

Difference Between Microprogrammed and Hardwired Control Unit

Overview of Control Units

The control unit is a critical component of the CPU that directs the execution of instructions by generating control signals. Based on how these control signals are generated, control units are classified into microprogrammed and hardwired types.

These two types of control units differ in structure, design methodology, flexibility, and performance. Both serve the same purpose of guiding data flow within the CPU, but their internal functioning is

 

 

Q3. What is the role of RAID in disk storage? 10 

Ans  3.

Role of RAID in Disk Storage

RAID Technology

RAID stands for Redundant Array of Independent Disks, a data storage virtualization technology that combines multiple physical disk drives into one logical unit to improve performance, fault tolerance, or both. RAID is widely used in enterprise storage systems, data centers, and high-

 

 

Assignment SET – II

 

Q4. Explain in detail RISC and CISC architectures?       5+5     

Ans 4.

RISC Architecture

RISC stands for Reduced Instruction Set Computer, an architectural design philosophy that emphasizes a small set of simple instructions. The idea behind RISC is that by simplifying the instruction set, the CPU can execute instructions faster and more efficiently. Each instruction is designed to execute in a single clock cycle, which allows for high-speed processing and improved

 

Q5. Differentiate between multiprocessing and multiprogramming.       10       

Ans 5.

Difference Between Multiprocessing and Multiprogramming

Multiprocessing

Multiprocessing refers to a system having two or more CPUs (Central Processing Units) that work in parallel to execute multiple processes simultaneously. In a multiprocessing system, multiple processors share a common physical memory and work under the control of a single operating system.

Multiprocessing can be of two types: symmetric and asymmetric. In symmetric multiprocessing (

 

Q6. What are hazards in pipeline processing? Discuss the hazards and suggest techniques to overcome them.            5+5     

Ans 6.

Hazards in Pipeline Processing and Solutions

Pipeline Hazards

Pipeline processing is used in modern CPUs to overlap instruction execution, thus improving overall performance. However, pipelines can face issues called hazards, which delay instruction execution and reduce efficiency. Hazards arise when the next instruction cannot execute in its designated
