1 But today there is a significant trend for functions to migrate so pronounced that it is likely the functions coded in firmware may soon exceed those in software on some systems.
2 Text-oriented command interpreters require commands to be typed in ,while graphically oriented command interpreters let the the user interact with computer by pointing and clicking on an icon.
3 Multitasking allow more than two processes coexist in the memory,and each process is allocated a fixed time named time-slice to run in time sharing mechanism.
4 A timesharing user could locate and corret errors in seconds or minutes,rather than suffering the delats,often hours or days,in batch processing environments.
5 Multiuser platforms support workgroup computing,situations in which LANs are set up to allow users to share files,databases,and applications.
6 The concept of distributed processing will cause the development of dispersed operating systems in which operating systems functions are distributed among many processors throughout large networks.
