a. Central Processing Unit (CPU):

• The Central Processing Unit (CPU) is the main component of a computer that processes and executes instructions
• What does the acronym CPU stand for?

  Central Processing Unit
• The CPU processes instructions from memory to perform tasks in a computer.


  True
• The Control Unit in a CPU coordinates the operation of other components
• Match the CPU component with its function:

  Arithmetic Logic Unit (ALU) ↔️ Performs arithmetic and logical operations

  Control Unit (CU) ↔️ Coordinates CPU operations

  Registers ↔️ Stores data and instructions temporarily
• Why is CPU caching important for performance?

  Reduces memory access time
• The main components of the CPU include the Arithmetic Logic Unit (ALU), Control Unit (CU), and Registers
• The Control Unit fetches instructions from memory.


  True
• Steps in the CPU instruction cycle:

  1️⃣ Fetch

  2️⃣ Decode

  3️⃣ Execute
• The ALU performs both arithmetic and logical operations.

  True
• The CPU is composed of the ALU, CU, and Registers
• The ALU processes data from registers and returns results to them.


  True
• Which step in the instruction cycle retrieves data from memory?

  Fetch
• The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations such as AND, OR, and NOT
• What is the purpose of registers in the CPU?

  Temporary data storage
• What are the key roles of the CPU in a computer?

  Fetch, decode, execute
• Match the CPU component with its function:

  ALU ↔️ Arithmetic and logical operations

  CU ↔️ Coordinates CPU operations

  Registers ↔️ High-speed data storage
• The ALU processes data from registers and returns results to them.

  True
• What is the second main responsibility of the CU after fetching instructions?

  Decode the instructions
• The clock speed of a CPU is measured in Hertz
• Match the CPU generation with its key feature:

  Gen 1 (Pentium) ↔️ Single-core

  Gen 2 (Core 2 Duo) ↔️ Dual-core

  Gen 3+ (i5, i7) ↔️ Quad-core or more
• Multi-core processors enable parallel processing and enhanced performance.


  True
• Steps in the instruction processing cycle of the CPU

  1️⃣ Fetch instruction from memory

  2️⃣ Decode the instruction

  3️⃣ Execute the instruction
• The CPU's fetch function retrieves instructions and data from memory
• What are the three main components of the CPU?

  ALU, CU, Registers
• Match the CPU function with its description:

  Fetch ↔️ Retrieves instructions and data from memory

  Decode ↔️ Interprets the instructions

  Execute ↔️ Carries out the instructions
• The Control Unit (CU) coordinates the operation of the other CPU components
• Steps involved in the CPU's instruction processing cycle:

  1️⃣ Fetch

  2️⃣ Decode

  3️⃣ Execute
• What is the primary function of the CPU in a computer?

  Process and execute instructions
• What type of operations does the Arithmetic Logic Unit (ALU) perform?

  Arithmetic and logical
• Responsibilities of the Control Unit (CU):

  1️⃣ Fetch instructions from memory

  2️⃣ Decode the instructions

  3️⃣ Control the flow of instructions
• A higher clock speed in a CPU leads to faster instruction processing.

  True
• Which CPU generation introduced dual-core processors?

  Gen 2 (Core 2 Duo)
• Multi-core CPUs execute instructions in parallel
• A multi-core CPU has two or more processing cores
• What is the main limitation of a single-core CPU in terms of performance?

  Sequential instruction execution
• Multi-core CPUs can handle multiple tasks concurrently.


  True
• CPU caching uses high-speed memory to store frequently accessed data
• Arrange the levels of CPU cache from fastest to slowest access speed:

  1️⃣ L1 Cache

  2️⃣ L2 Cache

  3️⃣ L3 Cache
• CPU caching helps bridge the performance gap between the fast CPU and the slower main memory
