Network Operating Systems vs. MUOS (Multi-User) Characteristics Different methods of Multi-tasking Multi tasking is when the operating system seems to be performing two or more tasks at the same time‚ i.e. MS Word and MS Access‚ however these tasks are not actually running simultaneously as they are actually resident in memory processor is actually switching between tasks at a very high speed‚ therefore each user sees their own task as having priority. One disadvantage can be that the more

Memory management in multiple operating systems An operating system is responsible for assigning memory to processes so that processes can be executed. Broadly‚ this responsibility is defined as memory management‚ and operating systems handle memory management differently. Any operating system must do two things in order to handle memory effectively. First‚ an operating system must be able to allocate and free physical memory. Second‚ an operating system must have techniques in place to keep

Components of an Operating System In order to perform the actions requested by the computer’s users‚ an operating system must be able to communicate with those users. The portion of an operating system that handles this communication is often called the user interface. Older user interfaces‚ called shells‚ communicated with users through textual messages using a keyboard and monitor screen. More modern systems perform this task by means of a graphical user interface (GUI) in which objects to be
