functions which programs may use to perform specific tasks especially
relating to interfacing with computer system components.

a) Choice of processor and hardware for example if server machine is a
Sun computer then will be forced to use Solaris which is Sun's version
of UNIX.

b) A hardware or software protocol, contained in the electronics of
the disk controller and disk drive, that manages the exchange of data
between the drive and computer. The most common interfaces for small
computer systems are AT (IDE) and SCSI.

c) Compatibility of computer networks types including LANs and WANs,
for example UNIX and Window NT are usually use to become the mainframe
of WANs networking system.

a)Multi tasking - In a multitasking operating system where multiple
programs can be running at the same time, the operating system
determines which applications should run in what order and how much
time should be allowed for each application before giving another
application a turn. Examples of multi tasking operating system are
UNIX and Window 2000.

b)Multi processing - An operating system capable of supporting and
utilizing more than one computer processor for example Linux, UNIX,
Windows 2000.

c)Multi user - A multi user operating system allows for multiple users

The popularity of computers and LANs grew to the point that some organisations recognised the need to account for the cost of assets and time spent on support. Industry analysts, using Total Cost of Ownership (TCO) techniques, have studied the real costs and found that they are around 6-7 times the initial purchase price over the lifetime of the technology....   [tags: Computing] 832 words
