serial chip
A "serial to parallel" converter converts a serial data connection to a parallel data connection. For example, in computer storage, there are controller chipsets that convert SATA (Serial ATA) to PATA (Parallel ATA, also called IDE or EIDE).
A serial port only allows a single bit of data through at a time. A parallel port allows multiple bits of data through at a time.
A Parallel bus has a relatively large number of wires bundled together that enable data to be transferred in parallel. This increases the throughput, or rate of data transfer, between the peripheral and the computer. A Serial bus can be defined as a transmission path over which the participants transmit their data serially, sequentially in time, and using a common medium. In the case of serial transmission, only a single communication link for transferring data from any given end to another one. In the case of parallel transmission, we use multiple numbers of parallel links for the simultaneous transmission of all the data bits in the network.
Parallel data transmission is faster compared to serial data transmission. The speed of a parallel link is equal to the number of bits sent multiplied by the bit rate of each individual path.
The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
Speed... a serial connection can only send one piece of data at a time. Parallel connections have multiple data 'channels' sending data simultaneously 0- which increases the data rate considerably.
Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
Its Parallel and Serial
OG MUDBONE says it cheaper
COM ports transfer data using a serial connection as opposed to a parallel connection.
