Operating Systems

• Manage resources, provide user interface, and run
  applications
• 3 basic categories of O.S. are embedded, network,
  and stand-alone
• Most popular O.S. is Microsoft Windows

• Also known as desktop operating systems
• Control a single desktop or notebook computer
• Located on the computers hard drive

• If part of a network they work together with NOS
• Windows, Mac OS, and some versions of UNIX are

• Antivirus programs that guard against viruses
• Uninstall programs that allow safe removal

• Backup programs that make copies of files in case
  of loss or damage
• File Compression programs that reduce the size of
  files to allow for more storage space
