The control unit is responsible for directing the flow of data and instructions between the various components of the computer system, ensuring that operations are performed in the correct sequence.

Input/Output (I/O) devices are not considered basic components of a computer system because they are external devices that are connected to the computer system to allow for communication with the outside world.

The memory unit is responsible for storing data and instructions that are being processed by the computer system.

Hard Disk Drive (HDD) is a storage device, not a type of computer memory.

The arithmetic logic unit (ALU) is responsible for performing arithmetic and logical operations on data.

Expansion Bus is not a type of computer bus, but rather a slot on a motherboard that allows for the addition of expansion cards.

Input/output (I/O) devices allow the computer system to communicate with the outside world, such as receiving input from a keyboard or displaying output on a monitor.

The Internet is not a type of computer network, but rather a global network of interconnected computer networks.

A network interface card (NIC) allows a computer system to connect to a network.

Hardware is not a type of computer software, but rather the physical components of a computer system.

An operating system (OS) is responsible for managing hardware resources, providing a user interface, and running application software.

Operating System is not a type of application software, but rather a system software that manages hardware resources and provides a user interface.

Firmware provides basic instructions to the hardware, allowing it to perform basic functions.

RISC Architecture is not a type of computer architecture, but rather a design philosophy that emphasizes the use of a small number of simple instructions.

A compiler translates high-level language code into machine code, which can be executed by the computer.
