CD ROM Drive Operating System An operating system is a set of instructions that control the operation of the computer and its peripheral devices. Operating systems control the execution of specific program. Operating systems provide support for activities like input and output (I/O) Examples: Windows XP, 2000 or NT, UNIX, OS2, Linex Stand Alone vs Networked Stand Alone Networked Stand Alone

A self sufficient computer All software must be loaded onto hard drive or run off a floppy. Printer, scanner, etc., connected directly to computer. Networked Behrend Computer Labs Multiple computers connected to one central location by cables, routers, etc.

One copy of the software on the server. Site license controls number of copies that may be downloaded at one time. Initial software downloads times may take up to 40 minutes depending on the software May connect to a printer in any computer center lab Store data (your files) on computer center server, i.e., your P: drive. Freshman allocated 10 MB.
