PORTS AND PC COMPONENTS
This is a serial port
-A serial port is a serial communication interface through which
information transfers in or out one bit at a time (in contrast to a
parallel port).
-Throughout most of the history of personal computers, data was
transferred through serial ports to devices such as modems,
terminals, and various peripherals.
This is a parallel port
-A connector for a device that sends or receives several bits of data simultaneously by using more than one wire
The parallel port is found on the back of the
computer and is part of the motherboard. Below is an example of the DB25 interface found on the back of the computer..

This is a VGA port
-Abbreviated VGA, Video Graphics Array is a standard type of connection for video device such as monitors and projectors.
-VGA cables have 15-pin connectors: 5 pins at the top, 5 in the middle, and the other 5 at the very bottom.
-A VGA port on a desktop or laptop naturally has the same number of pin holes so that a VGA cable can plug directly into it.
-A USB port is a standard cable connection interface for personal computers and consumer electronics devices.
-USB ports allow USB devices to be connected to each other with and transfer digital data over USB cables.
-
This is a firewire port
-Firewire is most often used to connect digital camcorders, external hard drives, and other devices that can benefit from the high transfer rates (up to 480 Mbps) supported by the Firewire connection.
-
This is Ethernet port.
-Ethernet is a family of computer networking technologies commonly used in local area networks (LANs) and metropolitan area networks (MANs)
-
This is a CPU
-A computer's CPU handles all instructions it receives from hardware and software running on the computer.
-
This is a hard drives
-A hard disk drive (HDD), hard disk, hard drive or fixed disk[b] is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
-The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, and 2.5-inch, primarily for laptops.
This is a Optical drives
-Optical drives retrieve and/or store data on optical discs like CDs, DVDs, and BDs (Blu-ray discs), any of which hold much more information than previously available portable media options like the floppy disk.
-The sides of the optical drive have pre-drilled, threaded holes for easy mounting in the 5.25-inch drive bay in the computer case.

This is a graphic cards
-A video card is an expansion card which generates a feed of output images to a display.
