central processing unit (CPU)"Brain" of the computer. Microprocessor that handoles primary calculations for the computer. CPUs are known by names such as Core i5 and Phenom.
connectorssmall receptacles used to attach cables to a system. Common types of connectors include USB, PS/2, and DB-25
DB ConnectorsD-shaped connectors used for a variety of connections in the PC and networking world. Can be male (with prongs) or female (with holes) and have a varying number of pins or sockets. Also called D-sub, D-subminiature, or D-shell connectors
Digital Video Interface (DVI)Special video connector designed for digital-to-digital connections; most commonly seen on PC video cards and LCD monitors. Some versions also support analog signals with a special adapter.
D-SubminiatureDB connectors, D-sub, or D-shell connectors.
eSATASerial ATA-based connector for external hard drives and optical drives.
Expansion SlotsConnecors on a motherboard that enable users to add opptional components to a system.
FireWireInterconnection standard to send wide-band signals over a serialized, physically thin connector system. Serial bus developed by Apple and Texas Instruments; enables connection of 63 devices at speeds u0p to 800 megabits per second.
floppy driveSystem hardware that uses removable 3.5-inch disks as storage media.
hard driveStores programs and data that are not currently being used by the CPU.
Hi-Definition Multimedia Interface (HDMI)Single multimedia connection that includes both high-definition video and audio. One of the best connections for out-putting to television. Also contains copy protection features.
hot-swappableAny hardware that may be attatched to or removed from a PC without interrupting the PC's normal processing.
IEEELeading standards-setting group in the United States
jackPart of a connector into which a plug is inserted. Also referred to as ports.
joystickPeripheral often used while playing computer games; originally intended as a multipurpose input device.
keyboardInput device. Three common types of keyboards: those that use a mini-DIN (PS/2) connection, those that use a USB connection, and those that use wireless technology.
microprocessor"Brain" of a computer. Primary computer chip that determines relative speed and capabilities of the computer. Also called CPU.
mini-audio connectorVery popular, 1/8-inch diameter connector used to transmit two signals; perfect for stereo sound.
ModemDevice that converts a digital bit stream into an analog signal (modulation) and converts incoming analog signals back into digital signals (demodulation). Analog communications channel is ypically a telephone line, and analog signals are typically sounds.
monitorScreen that displays data from the PC. Can use either a cathode ray tube (CRT) or a liquid crystal display (LCD) to display images.
motherboardFlat piece of circuit board that resides inside your computer case and has a number of connectors on it. You can use these connectors to attach a variety of devices to your system, including hard drives, CD-ROM drives, floppy disk drives, and sound cards.
mouseInput device that enables users to manipulate a cursor on the screen to selct items.
network interface card (NIC)Expansion card that enables a PC to physically link to a network.
optical driveDrive used to read/write to optical disks, such as CDs or DVDs.
parallel portConnection for the synchronous, high speed flow of data along parallel lines to a device, usually a printer.
peripheralsAny device that connects to the system unit.
plugHardware connection with some sort of projection that connects to a port.
portIn networking, the number used to identify the requested service (such as SMTP or FTP) when connecting to a TCP/IP host. Examples: 80 (HTTP), 20 (FTP), 69 (TFTP), 25 (SMTP), and 110 (POP3).
Power supplyProvides the electrical power for a PC. Converts standard AC power into various voltages of DC electricity in a PC.
PrinterOutput device that can print text or illustrations on paper. Microsoft uses the term to refer to the software that controls the physical print device.
ProgrammingSeries of binary electronic commands sent to a CPU to get work done.
Random access memory (RAM)Memory that can be accessed at random; that is, which you can write to or read from without touching the preceding address. This term is often used to mean a computer's main memory.
RJ connectorUTP cable connector, used for both telephone and network connections. RJ-11 is a connector for four-wire UTP; usually found in telephone connections. RJ-45 is a connector for eightwire UTP; usually found in network connections.
Serial portCommon connector on a PC. Connects input devices (such as a mouse) or communications devices (such as a modem).
SoftwareSingle group of programs designed to do a particular job; always stored on mass storage devices.
Sony/Philips Digital Interface Format (S/PDIF)Digital audio connector found on many sound cards. Users can connect their computers directly to a 5.1 speaker system or reciever. S/PDIF comes in both a coaxial and an optical version.
SpeakersDevice that outputs sound by using magnetically driven diaphragm.
System unitmain component of the PC, in which the CPU, RAM, CD-ROM, and hard drive reside. All other device-the keyboard, mouse and monitor-connect to the system unit.
TrackballPointing device distinguished by a ball that is rolled with fingers.
universal serial bus (USB)General-purpose serial interconnect for keyboards, printers, joysticks, and many other devices. Enables hot-swapping devices.
Video Electronics Standards Association (VESA)Consortium of computer manufacturers that standardized improvements to common IBM PC components.
