What is the name of the temporary data storage area between a peripheral device and the CPU which compensates for the difference between their speeds?
The correct option is B Buffer
Buffer is the temporary
data storage area between a peripheral device and the CPU which compensates for
the difference between their speeds.
In computer science, a
data buffer (or just buffer) is a region of a physical memory storage used to
temporarily store data while it is being moved from one place to another.
Typically, the data is stored in a buffer as it is retrieved from an input
device (such as a microphone) or just before it is sent to an output device
(such as speakers). However, a buffer may be used when moving data between
processes within a computer. This is comparable to buffers in
telecommunication.
Buffers can be implemented
in a fixed memory location in hardware—or by using a virtual data buffer in
software, pointing at a location in the physical memory. In all cases, the data
stored in a data buffer are stored on a physical storage medium. A majority of
buffers are implemented in software, which typically use the faster RAM to
store temporary data, due to the much faster access time compared with hard
disk drives. Buffers are typically used when there is a difference between the
rate at which data is received and the rate at which it can be processed, or in
the case that these rates are variable, for example in a printer spooler or in
online video streaming.
