CPU Architecture

What is the main function of the Arithmetic Logic Unit (ALU) in the CPU?

• To fetch instructions from memory

• To perform arithmetic and logical operations

• To store data temporarily

• To control data flow between memory and peripherals

Which register in the CPU holds the address of the next instruction to be executed?

• Accumulator

• Instruction Register

• Program Counter

• Stack Pointer

In CPU architecture, what is the purpose of the Control Unit (CU)?

• To perform all arithmetic operations

• To decode and execute instructions

• To store data permanently

• To increase the clock speed of the CPU

What does the term "pipelining" refer to in CPU architecture?

• Increasing the size of the cache memory

• Executing multiple instructions simultaneously

• Fetching, decoding, and executing multiple instructions in overlapping phases

• Storing frequently used data close to the CPU

Which of the following is an example of a Reduced Instruction Set Computer (RISC) architecture?

• Intel x86

• AMD Ryzen

• ARM Cortex

• Motorola 68000

What does the term "clock speed" of a CPU measure?

• The amount of data a CPU can process per second

• The number of instructions a CPU can execute per second

• The number of cycles a CPU can complete per second

• The size of the CPU's cache memory

Which of the following components is NOT part of the CPU?

• ALU

• Control Unit

• Register

• RAM

What is the primary purpose of cache memory in a CPU?

• To permanently store data

• To increase the speed of data access by storing frequently used data

• To execute instructions

• To manage input and output operations

Which technique allows a CPU to handle multiple tasks simultaneously by switching between them quickly?

• Multitasking

• Multithreading

• Parallel Processing

• Pipelining

What is the purpose of the Instruction Register (IR) in a CPU?

• To store the current instruction being executed

• To store the address of the next instruction

• To store intermediate results of calculations

• To store the status of the CPU
