AGP (Accelerated Graphics Port): A computer with an AGP will allow you to add a video card that will greatly increase the speed at which the computer can display graphics.Bus: Refers to the path data travels on through a computer. Different computer models can have different bus speeds.CD-R (Compact Disk Recordable): This is a CD that can be recorded or 'burned' only once.CD-ROM (Compact Disk Read Only Memory): A CD that stores information a computer can read but not alter. A CD can hold less information than a DVD but is also less expensive.CD-RW (Compact Disk Re-Writable): This is a CD that can be recorded and re-recorded many times.DVD-ROM (Digital Video Disk Read Only Memory): A DVD that stores information a computer can read but not alter. A DVD can hold more information than a CD.DVD-RW (Digital Video Disk Re-Writable): This is a DVD that can store computer information that can be recorded and re-recorded many times. A DVD can hold more information than a CD.Ethernet: A common method of connecting computers to a Local Area Network or LAN. Most computers today have ethernet capability.Gigabyte (GB): This is a measurement of hard drive capacity.
One gigabyte is equal to about one billion bytes.Gigahertz (GHz): This is a measurement of processor speed. One gigahertz is equal to one billion hertz.Hard drive: Also called a hard disk. This is where the computer permanently stores information, including the operating system and other software. This size of a hard drive is usually expressed in gigabytes (GB).Hardware: The physical components of a computer system such as the keyboard, monitor and tower.LCD (Liquid Crystal Display): This is a type of monitor that has a flat screen as opposed to a more traditional curved glass tube screen. LCD monitors are thin and lightweight and have little to no glare.Megabyte (MB): This is a measurement of hard drive capacity. One megabyte is equal to about one million bytes.Megahertz (MHz): This is a measurement of processor speed. One gigahertz is equal to one million hertz.Memory: Also referred to as RAM, or Random Access Memory.
This is where the computer temporarily holds the data it needs to perform various functions. The more RAM a computer has, the less often it has to read information off of a disk.Modem (MOdulator/DEModulator): This is a device that allows a computer to connect to the Internet.PCI (Peripheral Component Interconnect): A computer can have one or more PCI slots, which allow you add on extra components such as sound cards.Processor: The computer's 'brain.' Processors are gauged by how fast they can access and interpret information, and this speed is measured in either megahertz (MHz) or gigahertz (GHz).RAM (Random Access Memory): The amount of RAM in your computer determines how much data your computer can handle at once. If a computer only has a small amount of RAM, the processor must work harder to shuffle data around, which results in slower performance. There are two basic types of RAM:SDRAM (Synchronous Dynamic Random Access Memory): This is the traditional, less expensive type of RAM.
It is still commonly found on low and mid-range models.DDR (Double Data Rate): This newer technology is faster than SDRAM, but also more expensive.Resolution: The number of pixels per square inch displayed by a monitor. Most monitors support many different resolutions. The higher the resolution, the sharper the picture displayed.Scanner: A device that can read text or images printed on paper (including photographs) and translate the information into an electronic computer file.SCSI (Small Computer System Interface): Pronounced 'scuzzy,' this is a way for external components such as a keyboard, mouse and printer to connect to a computer. It has been largely replaced by USB technology.Software: A general term for computer programs.USB (Universal Serial Bus): This is a common way for external components such as a keyboard, mouse and printer to connect to a computer. Unlike older SCSI technology, USB devices can be added to and removed without having to reboot the computer.
