|---|---|
| magnetic hard drive | One of magnetic hard drive two technologies used by hard drives where data is stored as magnetic spots on disks that rotate at a high speed. The other technology is solid state drive (SSD). |
| main board | The main main board board in the computer, Also called the system board. The CPU, ROM chips, DIMMs, RIMMs, and interface cards are plugged into the motherboard. |
| gigahertz | One million gigahertz Hz, or one million cycles per second. See hertz (Hz). |
| memory | Physical microchips memory that can hold data and programming, located on the motherboard or expansion cards. |
| microprocessor | Also called microprocessor a microprocessor or processor. The heart and brain of the computer, which receives data input, processes information, and executes instructions. |
| monitor | The most monitor commonly used output device for displaying text and graphics on a computer. |
| motherboard | The main board in the computer, Also called the system board. The CPU, ROM chips, DIMMs, RIMMs, and motherboard interface cards are plugged into the motherboard. |
| mouse | A pointing mouse and input device that allows the user to move a cursor around a screen and select items with the click of a button. |
| non–volatile memory | nonvolatile – Refers non–volatile memory to a kind of RAM that is stable and can hold data as long as electricity is powering the memory. |
| parallel ATA | An older parallel ATA IDE cabling method that uses a 40–pin flat or round data cable or an 80–conductor cable and a 40–pin IDE connector. See also serial ATA. |
| parallel port | A female parallel port 25–pin port on a computer that can transmit data in parallel, 8 bits at a time, and is usually used with a printer. The names for parallel ports are LPT1 and LPT2. |
| port | As applied port to services running on a computer, a number assigned to a process on a computer so that the process can be found by TCP/IP. Also called a port address or port number. |
| power supply | A box power supply inside the computer case that supplies power to the motherboard and other installed devices. Power supplies provide 3.3, 5, and 12 volts DC. Also called a power supply unit (PSU). |
| primary storage | Temporary storage primary storage on the motherboard used by the CPU to process data and instructions. Memory is considered primary storage. |
| printer | A peripheral printer output device that produces printed output to paper. Different types include dot matrix, ink–jet, and laser printers. |
| processor | Also called processor a microprocessor or processor. The heart and brain of the computer, which receives data input, processes information, and executes instructions. |
| program | A set program of step–by–step instructions to a computer. Some are burned directly into chips, while others are stored as program files. Programs are written in languages such as Visual Basic and C++. |
| protocol | A set protocol of rules and standards that two entities use for communication. |
