Hardware- CPU Flashcards
Boot program
The program that is used to start the computer. It
is automatically loaded so that its instructions can
be fetched when the computer is turned on, and it
eventually loads the operating system.
Central Processing Unit
CPU
The main component of the computer. It carries out all
the processing by fetching and executing instructions.
Clock speed
The speed at which the processor carries out instructions,
measured in Megahertz (MHz) or Gigahertz (GHz).
Core
Each single processor circuit capable of fetching and
executing instructions.
CPU cache
Memory buffer on the processor that stores instructions
which have been fetched before and allows them to be
fetched more quickly the next time.
Fetch–Execute cycle
The process by which programs are run on a computer.
The processor repeatedly fetches the instructions of the
program from memory and executes them.
Multi-core processor
A processor with more than one core (processor circuit)
which means it can fetch and execute more than one
instruction at a time.
