Topic #2: Operating System Concepts Flashcards
It refers to a program that can take advantage of a multicore computer running on more than one core at a time
Multithreading
It is a processor that is a single computing component with two or more independent processing units called cores
Multi-core processors
This refers to the software or hardware that is used to temporarily store information, often data, in a computer system
Cache
