CSCI2402Operating Systems Computer Networks

• - This module is concerned with the services
  provided by the major elements of systems
  software of a
• multi-tasking computer system.
• ?What is systems software?
• Special programs that help a computer system
  manage itself and its resources.
• The approach in this module is conceptual rather
  than focussing on systems programming .

3
Stand-alone system

• System resources are scarce.
• Users and application programs need
• to be able to use and manipulate them
• conveniently
• Their use needs to be managed
• efficiently and fairly.
• The Operating System is a resource
• manager.

4
The network system

• To achieve reliable communication, need to be
  concerned with
• Access
• Encoding
• Synchronisation
• Error Recovery
