Y10 Options Day 3.4

What is the definition of CPU?

• Central Processing Unit: The main part of the computer, consisting of the registers, ALU and control unit.

• Central Peripheral Unit: The device that connects external devices to the computer.

• Computer Power Unit: The component that supplies power to the computer.

• Central Program Utility: The software that manages computer programs.

What is the definition of Von Neumann architecture?

• Traditional computer architecture that forms the basis of most digital computer systems. Instructions are fetched, decoded and executed one at a time.

• A type of computer architecture where data and instructions are stored in separate memory units.

• A network architecture used for distributed computing systems.

• A programming paradigm that emphasizes object-oriented design.

What is the definition of Fetch-decode-execute cycle?

• The complete process of retrieving an instruction from storage, decoding it and carrying it out. Also known as the instruction cycle.

• A process used to store data permanently in the computer's memory.

• A method for transferring data between two computers over a network.

• A cycle that only involves fetching data from the hard disk.

What is the definition of ALU?

• Arithmetic Logic Unit: Performs calculations (e.g., x = 2 + 3) and logical comparisons (e.g., IF x > 3) in the CPU.

• Advanced Link Unit: Manages network connections in the CPU.

• Analog Logic Unit: Processes analog signals in the CPU.

• Application Layer Unit: Handles software applications in the CPU.

What is the definition of Control unit?

• Decodes instructions. Sends signals to control how data moves around the CPU.

• Stores data and instructions temporarily.

• Performs arithmetic and logic operations.

• Connects the CPU to external devices.

What is the primary function of a processor core in a computer system?

• To execute instructions as part of the fetch-decode-execute cycle.

• To store data permanently for future use.

• To provide power to the computer components.

• To display images on the monitor.

What is the definition of Cache?

• Memory in the processor that provides fast access to frequently used instructions and data.

• A type of permanent storage used to save files and documents.

• A device that connects multiple computers in a network.

• A software program that manages hardware resources.

Which of the following is an example of a register in a computer's CPU?

• Memory Address Register

• Control Unit

• Cache Memory

• Program Counter

What is the definition of Bus?

• Communication system that transfers data between components inside a computer.

• Binary User System

• Allows cool air from the fan to reach the CPU

• Manages power distribution acroess internal components

Which of the following best describes the main characteristic of an embedded system?

• It is designed to perform a dedicated function within a larger system.

• It can be easily reprogrammed for any task.

• It is mainly used for browsing the internet.

• It is always portable and battery-operated.
