Understanding Computer Components1

What are output devices and give two examples?

• Keyboard and mouse

• Speakers and headphones

• Scanner and webcam

• Examples of output devices are a monitor and a printer.

Explain the primary function of the CPU.

• The CPU primarily stores data and files.

• The CPU is responsible for managing network connections.

• The primary function of the CPU is to execute instructions and process data.

• The CPU's main role is to provide power to the computer.

List the major functional parts of a CPU.

• Memory Management Unit (MMU)

• Input/Output Interface (IO)

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

• Cache Memory Unit (CMU)

What is a microprocessor?

• A microprocessor is a software program that manages computer resources.

• A microprocessor is a type of memory used in computers.

• A microprocessor is the main processing unit of a computer, integrating the functions of a CPU on a single chip.

• A microprocessor is a peripheral device that connects to a computer.

Describe the role of the Control Unit in a CPU.

• The Control Unit is responsible for memory allocation in the system.

• The Control Unit manages the power supply to the CPU.

• The Control Unit directs the operation of the processor and coordinates the execution of instructions.

• The Control Unit stores data temporarily for quick access.

What does ALU stand for and what is its function?

• Arithmetic Logic Unit

• Arithmetic Linear Unit

• Arithmetic Logic Unit Test

• Analog Logic Unit

Define buses in the context of computer architecture.

• Buses are the main power supply units for computer components.

• Buses are communication systems that transfer data between components in a computer.

• Buses are physical storage devices in a computer system.

• Buses are types of software applications used for data processing.

What is the difference between RAM and ROM?

• RAM is used for permanent storage; ROM is used for temporary storage.

• RAM is non-volatile and used for temporary storage; ROM is volatile and used for permanent storage.

• RAM and ROM are both volatile and used for the same purpose.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

How does main memory differ from secondary storage?

• Main memory has a larger capacity than secondary storage.

• Main memory is volatile and temporary, while secondary storage is non-volatile and permanent.

• Main memory is used for long-term data storage, while secondary storage is for short-term access.

• Main memory is permanent, while secondary storage is temporary.

What is the purpose of cache memory in a CPU?

• To store all data permanently for the CPU.

• To increase the physical size of the CPU.

• To manage power consumption of the CPU.

• The purpose of cache memory in a CPU is to speed up data access and improve processing efficiency by storing frequently used data and instructions.
