Computer Fundamentals Practice Test: Processor & Memory — Flashcards

Processor & Memory topics include: CPU and control unit, registers, cache memory, main memory organisation, processor and its types.

A computer's processor, also known as the CPU, is the brain of the computer. It provides the instructions and processing power for the computer to do its work. 

A computer's memory is the component that stores data and instructions that are needed by the CPU to perform its tasks. RAM, or Random Access Memory, is a temporary storage area that your computer uses for data it needs to run its current processes. RAM is volatile memory, meaning its contents get destroyed as soon as the computer is switched off. 

Here are some other things to know about processors and memory:
Processor memory: Processor memory, also known as "cache memory," is a type of memory that is located inside the CPU and is used to speed up the processing of data.
Processor and RAM communication: The CPU and RAM of a computer communicate using a system of wires, called a bus. This bus usually has three parts, the address bus, the control bus, and the data bus.
Processor and memory balance: A well-balanced combination of processor and memory is necessary for a computer to perform well. Neither a large memory size with a slow processor nor a fast processor with a small memory size can optimize your computer performance.
Graphics-heavy programs: Graphics-heavy programs generally require a faster processor.
