For a long time, it spreads quickly as the standard which is substituted to the ISA bus which is de facto standard presently is adopted for most personal computers. As for first PCI standard, bus width (the data quantity which can be sent with the transfer of 1 times) at 32 bits operational frequency 33MHz. Maximum data rate was 133MB/s. With up-to-date standard 64 bits in bus width, the high speed of maximum 533MB/s also specification is stipulated with 66MHz operation. In addition, there is also a standard, PCI-X which expands PCI in for the serve
