__//Main Characteristics of Computer systems//__
 * **Single user systems** are systems that only allow for one user to access the computer at a time
 * **Multi User systems** are systems that allow continuous access of multiple users at once and that are capable of running more than one process at a time in order to maximize the potential of all users
 * **Example:** a server / computer where several people access a server / computer remotely
 * **Single Tasking** is a reference to when a system is only doing one task at a time
 * **Multi Tasking** allows a computer to run more than one task at a time by scheduling what tasks to do when in order to not have the computer make mistakes or do the wrong thing.
