Chapter13- Architecture(Pt1)-Internal Components

What architecture do most modern computers use?

• Von Neumann architecture

• Harvard architecture

• Turing architecture

• Babbage architecture

What is the main function of the Central Processing Unit (CPU)?

• To store data permanently

• To interpret and carry out basic instructions

• To connect external devices

• To manage power supply

Which component is known as the 'brain' of the computer?

• Central Processing Unit (CPU)

• Motherboard

• System Bus

• Secondary Storage Device

What does the Arithmetic Logic Unit (ALU) do?

• Loads data from input registers and performs operations

• Stores data permanently

• Connects the computer to the internet

• Manages power supply

What is the role of the control unit (CU) in the CPU?

• Extracts instructions, decodes and executes them

• Stores data permanently

• Connects external devices

• Manages power supply

What are the two types of tasks a CPU can perform?

• Arithmetic computations and logical operations

• Data storage and retrieval

• Networking and communication

• Graphics rendering and sound processing

What is the function of the accumulator (ACC) register?

• Stores the address of the next instruction

• Holds a copy of the instruction currently being executed

• Used for short-term storage of arithmetic and logic data

• Holds the address in memory of the next data element to be fetched

Which register holds the address of the next instruction to be fetched/executed?

• Accumulator (ACC)

• Program counter (PC)

• Current instruction register (CIR)

• Memory data register (MDR)

What is the main difference between 32-bit and 64-bit processors?

• 32-bit processors can handle more data at once

• 64-bit processors can address more memory

• 32-bit processors are faster

• 64-bit processors are only used in servers

What is the role of the memory address register (MAR)?

• Holds data that has just been fetched from memory

• Holds the address in memory of the next data element to be fetched

• Holds a copy of the instruction currently being executed

• Used for short-term storage of arithmetic and logic data
