hibernate mode - A power management mode that saves everything in memory to a reserved space on the hard drive and then turns off the computer. When you restart the computer, the memory information that was saved to the hard drive is automatically restored. HTML - hypertext markup language - A set of codes inserted into an Internet web page intended for display on an Internet browser. HTTP - hypertext transfer protocol - A protocol for exchanging files between computers connected to the Internet. Hz - hertz - A unit of frequency measurement that equals 1 cycle per second. Computers and electronic devices are often measured in kilohertz (kHz), megahertz (MHz), gigahertz (GHz), or terahertz (THz). I IC - Industry Canada - The Canadian regulatory body responsible for regulating emissions from electronic equipment, much as the FCC does in the United States. IC - integrated circuit - A semiconductor wafer, or chip, on which thousands or millions of tiny electronic components are fabricated for use in computer, audio, and video equipment. IDE - integrated device electronics - An interface for mass storage devices in which the controller is integrated into the hard drive or CD drive. IEEE 1394 - Institute of Electrical and Electronics Engineers, Inc. - A high-performance serial bus used to connect IEEE 1394-compatible devices, such as digital cameras and DVD players, to the computer. infrared sensor - A port that allows you to transfer data between the computer and infrared-compatible devices without using a cable connection. integrated - Usually refers to components that are physically located on the computer's system board. Also referred to as built-in. I/O - input/output - An operation or device that enters and extracts data from your computer. Keyboards and printers are I/O devices. I/O address - An address in RAM that is associated with a specific device (such as a serial connector, parallel connector, or expansion slot) and allows the microprocessor to communicate with that device. IRQ - interrupt request - An electronic pathway assigned to a specific device so that the device can communicate with the microprocessor. Each device connection must be assigned an IRQ. Although two devices can share the same IRQ assignment, you cannot operate both devices simultaneously. ISP - Internet service provider - A company that allows you to access its host server to connect directly to the Internet, send and receive e-mail, and access websites. The ISP typically provides you with a software package, user name, and access phone numbers for a fee. K Kb - kilobit - A unit of data that equals 1024 bits. A measurement of the capacity of memory integrated circuits. KB - kilobyte - A unit of data that equals 1024 bytes but is often referred to as 1000 bytes. keyboard shortcut - A command requiring you to press multiple keys at the same time. Also referred to as a key combination. kHz - kilohertz - A measurement of frequency that equals 1000 Hz. L LAN - local area network - A computer network covering a small area. A LAN usually is confined to a building or a few nearby buildings. A LAN can be connected to another LAN over any distance through telephone lines and radio waves to form a wide area network (WAN). LCD - liquid crystal display - The technology used by portable computer and flat-panel displays. LED - light-emitting diode - An electronic component that emits light to indicate the status of the computer. local bus - A data bus that provides a fast throughput for devices to the microprocessor. LPT - line print terminal - The designation for a parallel connection to a printer or other parallel device. M Mb - megabit - A measurement of memory chip capacity that equals 1024 Kb. Mbps - megabits per second - One million bits per second. This measurement is typically used for transmission speeds for networks and modems. MB - megabyte - A measurement of data storage that equals 1,048,576 bytes. 1 MB equals 1024 KB. When used to refer to hard drive storage, the term is often rounded to 1,000,000 bytes.
