We can upgrade the memory of the computer by the adding extra RAM to the memory
slots in motherboard in order to increase the overall performance of the computer.
Random Access Memory (RAM) is the kind of data storage in the computer in which
any storage location can be accessed directly. Both the size and capacity of RAM
are lower than the hard disk.
Purpose of RAM
The programs and data that we are currently using are stored in the
RAM temporarily so that the processor can access them quickly.
|
This is because the RAM access
time is faster which is in nanoseconds compared to the hard disk access time which
is in milliseconds.
So if we have more RAM in our computer, the number of times
the processor has to access the data from the hard disk is decreased.
RAM is generally available in multiples of 16 like16MB, 32MB, 128 MB or higher.
Almost everyone are using at least 1 GB of RAM for their computers today but 2 GB
RAM provides even better performance of the computer while using Windows Vista or
using applications like Photoshop.
