Ports
Ports are computer components designed to connect peripheral devices to the computer. //Serial Ports// send and recieve data one bit at a time, while //Parallel Ports// are used for devices that send and recieve data in groups of bits, rather than sequentially.



__Legacy Ports__
A legacy port is a port or connector on a PC that is considered fully or partially obsolete (outdated) - They are far too slow for today's needs. Because of this, manufacturers, particularly in laptops, remove the legacy ports altogether, making way for more modern ports like USB.

__USB Ports__
Universal Serial Bus establishes communication between devices and a host controller (usually personal computers). It is most widely used hardware interface for attaching peripherals to a computer.USB devices are "hot swappable;" they can be plugged in and unplugged while the computer is on. The original USB only allowed approximately 11Mbps data to be transmitted. since USB 1.0 doesnot transfer large amount of data it has been replaced by USB 2.0 which has data transfer rate of up to 840 Mbps.

__**FireWire **__  It is a high-speed connection standard developed by apple. FireWire provides a single plug-and-socket connection on which up to 63 devices can be attached with data transfer speeds up to 400Mbps.The standard describes a serial bus or pathway between one or more peripheral devices and your computer's microprocessor.

__**Ethernet **__ A socket on a computer or network device for plugging in an Ethernet cable.

__**Serial port**__  A serial port is a serial communication physical interface through which information transfers in or out one bit at a time.

__**Parallel port**__
