Exploring Computer Organization Concepts

What are the main components of CPU architecture?

• Arithmetic Logic Unit (ALU), Control Unit (CU), Registers

• Cache Memory (CM)

• Input/Output Interface (IO)

• Memory Unit (MU)

Explain the difference between RISC and CISC architectures.

• RISC uses a small set of simple instructions for efficiency, while CISC uses a larger set of complex instructions for more functionality.

• CISC is designed for mobile devices, while RISC is used in desktop computers.

• RISC uses a larger set of complex instructions, while CISC uses a small set of simple instructions.

• RISC and CISC both use the same instruction set but differ in execution speed.

What is the purpose of the ALU in a CPU?

• The purpose of the ALU in a CPU is to perform arithmetic and logical operations.

• To store data temporarily during processing.

• To control the flow of data between memory and storage.

• To manage input and output devices.

Describe the role of the control unit in CPU operation.

• The control unit stores data temporarily for quick access.

• The control unit orchestrates the execution of instructions in the CPU by fetching, decoding, and directing operations.

• The control unit manages the power supply to the CPU.

• The control unit handles memory allocation for programs.

What is the significance of clock speed in CPU performance?

• Clock speed is significant as it determines the number of instructions a CPU can execute per second, impacting overall performance.

• Clock speed affects the physical size of the CPU chip.

• Higher clock speed reduces power consumption significantly.

• Clock speed is irrelevant to the number of cores in a CPU.

Define the memory hierarchy in computer systems.

• Main memory, hard drives, and flash storage.

• Registers, main memory, and network storage.

• Registers, cache, and virtual memory only.

• The memory hierarchy consists of registers, cache, main memory (RAM), and secondary storage.

What are the different types of memory in the memory hierarchy?

• Registers, Cache Memory, Main Memory (RAM), Secondary Storage

• Virtual Memory

• Flash Memory

• Optical Disks

Explain the concept of virtual memory.

• Virtual memory is a technique that only uses RAM without any disk space.

• Virtual memory is a type of physical memory found in computers.

• Virtual memory is a method to increase the speed of the CPU.

• Virtual memory is a memory management technique that uses disk space to extend RAM, allowing for larger applications to run.

What is the purpose of cache memory in a computer system?

• To increase the storage capacity of the hard drive.

• To manage power consumption of the CPU.

• The purpose of cache memory is to speed up data access for the CPU by storing frequently used data and instructions.

• To provide a backup for the main memory.

Differentiate between L1, L2, and L3 cache.

• L1 cache is the fastest and smallest, L2 cache is larger and slower, and L3 cache is the largest and slowest, shared among cores.

• L1 cache is larger than L2, L2 cache is the slowest, and L3 cache is the fastest.

• L1 cache is shared among cores, L2 cache is the fastest, and L3 cache is the smallest.

• L1 cache is the largest and slowest, L2 cache is the fastest, and L3 cache is smaller than L2.
