Caching is a
storage tool on the computer which the data in a reserved memory. When the user
searches for the specific data then the cache memory helps him to get it a
faster rate. The instructions that are used repeatedly are mostly stored in the
cache memory and help the CPU to perform the task at a faster speed. Using the
cache memory for storing such information enables the CPU to avoid using the
system bus in the motherboard for transferring the data. He can process the
data at a faster rate by using the cache memory instead of processing it
through motherboard’s system bus. Using the latter slows down the system and
this is why caching is preferred.
The cache memory
is generally in the CPU and is referred to as level 1. However it may also be
on a separate unit near the CPU and is then called as level 2 cache. A computer
may both the cache memory. Using more caches in your system can help in
improving your system’s performance and is therefore considered to be very
useful. It is best to buy a computer
with a built in cache memory as it enjoys a better efficiency and makes the
system faster.
