How do computers process information?
Input devices accept data in a form that the computer can use; they then send the data to the processing unit. The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want.
What happens to a file when it is saved?
Save is writing data to a storage medium, such as a floppy disk, CD-R, USB flash drive, or hard drive.
