The performance of a computer in
terms of processing speed is related to
Processor
Chip type
Primary
Memory size, and
Clock
Pulse.
The amount of information a
computer can hold is dependent on its Secondary Memory (Hard Disk) size.
Usually the efficiency of a
computer is related to the Processor Chip, with more advanced chips giving
improved performance. The early PC
processor chips were known as 8086, 286, 386 and 486. These are all now obsolete, and have all been
superseded by the Pentium chip. The
Pentium chip is available in a range of different speeds; e.g. there is the
Pentium 166 and Pentium 200. The Pentium
200 is faster than a Pentium 166.
It is also important that the
computer has sufficient random access memory i.e. RAM. If there is adequate RAM, the computer can be
fast if configured well, and will be able to run many programs concurrently
without running out of memory. A good
office computer should have from 32MB of RAM.
Performance is also related to
the speed of accessing the hard disk, for I-O (input output) operations. Hard disks come in different speeds, some
IDEs are now faster, i.e. their rate of data transfer is greater. Improvements in hard disk technology have
enabled the development of very large and very fast hard drives, at prices
affordable for home and small office computing.The combination of a modern
Processor chip, sufficient RAM and adequate Hard Disk storage space will
produce good performance.
However, it should be noted that
an upgrade of operating system or application software may degrade computer
performance, as the general tendency is for each upgrade to require greater RAM
and Hard Drive Resources.
