parallel and serial transmission
parallel transmissionParallel transmission occurs across a parallel wire. These wires are flat and thick and constitutes to a single wire. It carries a single bit of information (1 or 0). A parallel cable can carry multiple bits at the same time, one for each cable. An eight-cable parallel wire, for example, could carry an entire byte of data. This results in faster data transmission per second, all things being equal. serial transmissionSerial transmission occurs over a single cable, one bit at a time. This type of communication is named "serial" not simply because data travels one bit at a time, but also because these bits must be organized in a particular way so that transmissions can be organized and considered trustworthy. For example, a single transmission from a peripheral device using serial data might take only 6 bits, so the serial mechanism has a way to dictate how to signal things like an "end of transmission."
