PORTS AND PC COMPONENTS
VGA PORTS
•VGA stands for Video Graphic Array.
•It has three-row 15-pin DE-15 connector
•The VGA connector is used for display devices
•Is a female port
EXAMPLE DEVICES FOR VGA PORTS
•Video cards, Computer monitors, Laptop computers, Projectors, and High Definition television sets.
-
PARALLEL PORTS
•Parallel port is a type of interface found on computers (personal and otherwise) for connecting peripherals.
•Is a female port
•Has 25 pins.
EXAMPLE DEVICES FOR PARALLEL PORTS
•Used to connect printers, computers and other devices that need relatively high bandwidth.
USB
•USB stands for Universal Serial Bus•USB port is a standard cable connection interface for personal computers and consumer electronics devices
•The typical USB port is known as USB Type-A and has a simple, rectangular shape. EXAMPLE OF USB TYPE-A
•There is USB 1.0, 2.0 and 3.0. The later it is, it provides better speed and more efficient power management
-
SERIAL PORTS
•Serial port is a serial communication interface through which information transfers in or out one bit at a time
•Is a male port
•Has 9 pins. ( 5 from top and 4 from below )
-
-
FIREWIRE PORTS
•External connector,similar to a USB port, that provides a high-speed connection between a computer and peripheral devices.•Firewire was developed by Apple, Inc. and is based off the standard IEEE 1394 high performance serial bus.
DEVICES
•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.
ETHERNET
•An Ethernet port (aka jack or socket) is an opening on computer network equipment that Ethernet cables plug into.
FUNCTION
Their purpose is to connect wired network hardware in an Ethernet LAN, metropolitan area network (MAN), or wide area network (WAN).
DEVICE
•Most desktop computers include one built-in Ethernet port for connecting the device to a wired network.
CPU
• "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.•Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip.
-
FUNCTIONS
•(CPU) is the brain of your computer. It handles all the instructions you give your computer, and the faster it does this, the better.
OPTICAL DRIVES
•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.
• Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives.
GRAPHIC CARDS
•A video card (also called a display card, graphics card, display adapter or graphics adapter) is an expansion card which generates a feed of output images to a display (such as a computer monitor).
•At 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.
•A graphics card or video card often has its own cooling system, due to the large amount of power it uses and heat it produces.
Graphics cards have different types of connectors for connecting to a computer's motherboard.
CONNECTORS TYPES
•PCIe (Peripheral Component Interconnect Express) connector
•AGP (Accelerated Graphics Port) connectors
HARD DRIVES
•Hard disk drive (HDD), hard disk, hard drive or fixed disk 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.
•HDDs became the dominant secondary storage device for general-purpose computers by the early 1960s.
•Though SSDs have nearly 10 times higher cost per bit, they are replacing HDDs where speed, power consumption, small size, and durability are important.
