Q/ What is the vacuum
solution to increase the
speed of the computer The
CPU industry was developed
by using ........ inside the
processing unit to provide
the processor with the
required data
The computer memory module speed is specified in catalogs or literature either by the speed in MHz (for example DDR4-xxxx) or in MB/s (for example PC4-xxxx) or both.
For example, if the memory speed is DDR4-4700, then the corresponding speed in MB/s is PC4-______
