Hardware Flashcards
How does the central processing unit (CPU) work?
The CPU does something that is called the ‘IPOS’ Cycle. It stands for Input, Processing, Output, and Storage. It is a sequence where it processes the instructions, data, and information on the computer.
How does the IPOS Cycle work?
Input is given first to get the desired output and the input is processed before the output is released. In essence, the CPU takes instructions from a program/application and performs calculations.

Describe a mobile device.
A portable device with a compact form that connects to the internet wirelessly and has a rechargeable battery.
What is a server?
