Hi..... guys.... we are going to discuss an article on Operating System "User View"
User View- The user's view of the computer varies according to the interface being used. Most computer users sit in front of a PC , consisting of a monitor , keyboard , mouse , and system unit. Such as a system is designed for one user to monopolize its resources . The goal is to maximize the work (or play) that the user is performing in this case , the operating system is designed mostly for easy of use , with some attention paid to performance and none paid to resources utilization- how various hardware and software resources are shared . Performance is, of course , important to the user ; but such a system are optimized for the single users experience rather than the requirement of multiple users .
In other case , a user sits at a terminal connected to a mainframe or a minicomputer . Other users are accessing the same computer through other terminals. These users share resources and many exchange information . The operating system in such case is designed to maximize resources utilization - to access that all available CPU time, memory, and I/O are used efficiently and that no individual users takes more than her fair share .
In still other cases , users sit at workstations connected to networks of other workstations and servers . These users have dedicated resources at their disposal , but they also share resources such as networking and servers - file, computer and print servers . Therefor , their operating system is designed to compromise between individual usability and resource utilization ,
Recently , many varieties of handheld computer have come into fashion . Most of these devices are standalone units for individual users . Some are connected to networks, either directly by wore or (more often) through wireless modems and networking . Because of power, speed, ad interface limitations , they perform relatively few remote operations . Their operating system are designed mostly for individual usability , but performance per unit of battery life is important as well.
Some computers have little or no users view. For example , embedded computers in home devices and automobiles many have numeric keyboards and may turn indicator lights on or off to show status , but they and their operating systems are designed primarily to run without user intervention.
