Computer User

The user of a computer is a critical part of a complete computer system especially when a personal computer is involved. People tend to think of computer as intelligent devices, capable of performing amazing tasks. Computers have also been perceived by others as devices that can think and make decisions just as humans do, but this is not the case. Even the most powerful supercomputers require human interactions if for no reason to get them started and tell them which problems to solve. The role of users in computer systems include:

Installing software: Modern computers come with preinstalled operating systems and some other applications. However in order for a user to enjoy the usage it is required they install new applications to enable them use for particular tasks.
Managing files: Files on the computer can be created and be made available to open again for use. It is up to the user to store these files in locations that can be easier to remember or even password protect the files. Users can copy, delete and save videos, movies and audio for future retrieval.
Maintenance of systems: System maintenance does not necessarily mean opening the PC and fixing broken parts. It may require the services of a technician or can be tackled by the user. PC maintenance, however, generally means running utilities that keep the disks free of clutter and ensure that the computer is making the best use of its resources.
