PCI Express
Peripheral ports such as COM, USB and serial ports, are input/output interfaces that allow devices to connect to a computer. Expansion slots are sockets on the motherboard where an expansion card is inserted.
Usually it's a modem. Could be a communication cable to another device such as a Com cable to a router or switch. They aren't used that much anymore.
start bit signals receiver end to receive sequence of bits(data bits) and stop bit to signal the end of bit transmission.
what is serial processing
Universal Serial Bus (USB) is a serial bus standard to interface devices to a host computer.
parallel
A serial wire can be used for several uses. Mainly, it's used for basic communication between different devices. The main advantage is the fact that serial communication can use only three wires. Parallel requires several more, typically eight, or sixteen, plus signalling, and traditionally is faster. But for simple communication between devices, which could be computers or other devices, serial communication can simplify things. Serial communication can also be used for great distances. The telegraph was serial communication. Hence "AT&T"!
write a serial port program.then by shorting transmission and reception pin check whether interrupt has occured or not.....like that we can check serial port communication......... regards Parvathy
Assuming that by serial technologies you mean serial communication, here are some: USB - Universal Serial Bus RS232C - The original serial protocol
RS-232
These interface products turn regular USB ports into ports for serial products that can be connected to other serial components for communication uses.
It uses serial communication. There is polling employed.

SCSI uses a parellel communication chain and SAS uses serial Point to Point communication
try a null modem serial connection
one bit at a time
Most modern peripherals. USB devices, Firewire devices , SATA hard drives, PCI express cards and Ethernet are all examples of devices using serial communication.
