What is an Operating System?
Every computer requires an operating system
An operating system is the program that controls all the other parts of a computer system, both the hardware and the software. It allocates the computer's resources and schedules tasks.
UNIX is a multi-user, multi-tasking operating system. Multiple users may have multiple tasks running simultaneously. This is very different from PC operating systems. (e.g. Windows)

When using UNIX, things will go much more faster if you learn and use the following:
To switch between previously used commands, use theup and down arrows
If you f.ex are changing directory to documents, type cd do and hit TAB, then UNIX will fill out the rest of thename itself. If you have several directories that beginswith do, UNIX lists all of them if you hit TAB once more
Do not include special symbols or characters in file- and directory names. Such can be #, å, !, @. Do not use file- and directory names with an open space (instead of test file, use testfile or test_file)
