this is about advanced operating systems like:

  • apple mac os
  • windows
  • linux and unix

also network OS’s (NOS):

  • mac os x
  • linux and unix
  • windows 2000 and 03 server

os’s are basically the life of the computer they can be upgraded, like windows xp can be upgraded to windows 7. providing network resources to a client is designed by the NOS, access and security as well as the netework print queue.

there a few network protocols:

  • http- define the files exchanged on the web
  • ftp- provides services for file transfers and manipulation
  • pop- this can retrieve from an email server
  • dns- resolves urls for websites to their ip addresses
  • dhcp- automate the assignment of ip addresses.

this is just a few things for the curicluluum shortened to make it easier to understand
