2. Two Basic Components of a Computer System
Hardware
Software
Computer Instructions or data. Anything that can be stored electronically.
Parts of the Computer System you can physically touch.
Operating System
Application Software

3. How Does a Computer Work?
User Enters Data/Information - INPUT
The Computer PROCESSES the data/information
You then have the option to STORE/SAVE before you output
Produce an image of the processed data/information - OUTPUT
I relate the IPSO cyle to the human body….Hands/arms input, mouth chews/processes, stomach stores nutrients our body needs, waste is what the body discards/outputs that our body does not need/want.

Random Access Memory
Otherwise known as temporary memory. Data stored in RAM can be changed or deleted. Information placed in RAM is lost when the machine is shut down.
2. ROM
Read-Only Memory
Otherwise known as permanent memory or built-in directions. ROM contains the basic operating instructions for the computer and it can’t be changed.
