PORTs & PC COmPonentS
SERIAL PORT
1.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)
3.While such interfaces as Ethernet, FireWire, and USB all send data as a serial stream, the term "serial port"
2.Modern computers without serial ports may require serial-to-USB converters to allow compatibility with RS-232 serial devices
VGA PORT
-
2.15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, and high definition television sets
3.Many devices still include VGA connectors, although VGA generally coexisted with DVI as well as the newer and more compact HDMI and DisplayPort interface connectors
PARALLEL PORT
-
2.Parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals
3.A DB-25 connector often used for a parallel printer port on IBM PC compatible computers, with the printer icon.
USB PORT
-
2. Connectors and protocols for connection, communication, and power supply
-
4.Released in 1996, the USB standard is currently maintained by the USB Implementers Forum (USB IF)..
FIREWIRE PORT
-
1. IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer
-
-
ETHERNET PORT
-
2. Ethernet cables connect devices within a local area network, like PCs, routers, and switches.
-
-
CPU
(Central Processing Unit)
-
-
3.Performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
4. Traditionally, the term "CPU" refers to a processor
GRAPHIC CARDS
1.A video card (also called a display card, graphics card, display adapter or graphics adapter) is an expansion card
2.Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.
3. The core of both is the graphics processing unit (GPU), which is the main part that does the actual computations, but should not be confused as the video card as a whole, although "GPU" is often used to refer to video cards.
HARD DISK DRIVE
1.A hard disk drive (HDD), hard disk, hard drive or fixed disk.
2.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.
3. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.
1.Optical disc drive (ODD) is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs
2. Compact discs, DVDs, and Blu-ray
3. Optical disc drives that are no longer in production include CD-ROM drive, CD writer drive, combo (CD-RW/DVD-ROM) drive, and DVD writer drive supporting certain recordable and rewritable DVD formats
4.There are also the DVD-ROM drive, BD-ROM drive, Blu-ray Disc combo (BD-ROM/DVD±RW/CD-RW) drive, and Blu-ray Disc writer drive.
