RS232 is a standard protocol used for serial communication, it is used for connecting the computer and its peripheral devices to allow serial data exchange between them. As it obtains the voltage for the path used for the data exchange between the devices.

Category 5 cable (Cat 5) is a twisted pair cable for computer networks. Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 1000BASE-T.

In serial communication, 1 bit is transferred at a time. While in parallel, 8bits are being transferred at the same amount of time 1 bit is being transferred using serial device. Therefore, parallel transmission is faster than serial.

In a serial communication it uses one cable and we use when the distance is long, but parallel communication it uses many cables. So it is very expensive we use when the distance is short.

Parallel communication is a method of conveying multiple binary digits (bits) simultaneously.

Examples of parallel communication:IEEE-1284, ATA, PCI, ISA etc.

Institute of Electrical and Electronics Engineers (IEEE) resulted in the IEEE 1284 committee.

IEEE 1284 standard is the first approved standard for parallel communication for PCs.

What is the difference between parallel and serial communication?

RS-232 is approved standard for serial communication.
