The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated,
parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the
parity error is occurred and this is called single bit error detection.

Developed by Intel, Peripheral Component Interconnect (PCI) is a local bus standard. A bus is a channel used to transfer data to
(input) and from (output) a computer and to or from a peripheral device. Most PCs have a PCI bus usually implemented at
32-bits providing a 33 MHz clock speed with a throughput rate of 133 MBps.

Oversimplified, Plug-and-Play automatically tells the software (device drivers) where to find various pieces of hardware (devices)
such as modems, network cards, sound cards, etc. Plug-and-Play's task is to match up physical devices with the software
(device drivers) that operates them and to establish channels of communication between each physical device and its driver.
