It is usually measured in bits per second, or "bps."   Internet Terms BIOS   Basic Input/Output System. The BIOS is boot firmware, designed to be the first code run by a PC when powered on. The initial function of the BIOS is to identify, test, and initialize system devices   Software Terms byte The byte is a unit of digital information in computing and telecommunications. It is an ordered collection of bits, in which each bit denotes the binary value of 1 or 0. ...   Software Terms  C Case Metal housing that contains the workings of the computer   Hardware Terms cpu   Central Processing Unit. The chip in a computer that has primary responsibility for interpreting commands and running programs. The CPU is the most vital component of a computer system. The speed of the CPU has a significant impact on overall system performance   Hardware Terms  D ddr Double Data Rate ram Double data rate is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst. It is usually referred to as DDR as opposed to DDR SDRAM.   Hardware Terms DDR2 SDRAM double data rate synchronous dynamic random access memory interface. It supersedes the original DDR SDRAM specification and the two are not compatible.   Hardware Terms  E EEPROM Electrically Erasable, Programmable Read-only Memory A type of ROM that can be erased electronically and reprogrammed in-circuit (or with a device programmer). Short for Electrically Erasable Programmable Read Only Memory. From the programmer's perspective, EEPROM is very similar to flash memory. The biggest difference is that the bytes (words) of an EEPROM can be erased individually.   Hardware Terms  F Floppy 3.5 inch computer disk One of several types of magnetic storage media. The term "floppy" refers to any disk that is made of a flexible material, such as Mylar, instead of some type of metal. Almost all floppy disks used now are 3 ? inch(which hold a maximum of 1.44 megabytes). The smaller, higher capacity disks have become the industry standard, with their older, larger counterparts disappearing into obscurity.   Hardware Terms fsb Front Side Bus which denotes the speed at which your processor interacts with the components on the motherboard. Typically the FSB is 100Mhz or 133Mhz, but overclockers often manipulate this value to increase the speed at which their processor runs. ie 100Mhz FSB X 5.0 clock multiplier = 500Mhzprocessor.   Hardware Terms  G gigabyte A measurement of data capable of holding 1,024 megabytes. Gigabytes are used to store very large amounts of information.   Software Terms gpu graphics processing unit. (also occasionally called visual processing unit or VPU) is a specialized processor that offloads 3D graphics rendering from the microprocessor. It is used in embedded systems, mobile phones, personal computers, workstations, and game consoles.   Hardware Terms  H Heatsink   A heat sink is a colloquial term for a component or assembly that transfers heat generated within a solid material to a fluid medium, such as air or a liquid.   Hardware Terms  I isa Industry Standard Architecture ISA is an older technology for connecting computer peripherals (stands for Industry Standard Architecture). Common current devices include modems and sound cards. ISA is much slower than PCI, so PCI devices are generally better if you have a choice. ISA is starting to fade and eventually will be removed entirely. Most motherboards still come with at least one or two ISA slots on them.   Hardware Terms  K kilobyte   a unit of information equal to 1000 bytes   Software Terms  L LAN This stands for Local Area Network and refers to a computer network limited to a small area such as an office building, university, or even a residential home.   Hardware Terms  M megabyte   The megabyte is a multiple of the unit byte for digital information storage or transmission. This is roughly one million bytes. This is exactly 1,048,576 bytes (that's 1024 x 1024, or 2^20)   Software Terms Motherboard The "heart" of your PC -- it handles system resources (IRQ lines, DMA channels, I/O locations), as well as core components like the CPU, and all system memory. It accepts expansion devices such as sound and network cards.   Hardware Terms Multiplier The multiplier together with the fsb makes up the speed of a processor. A multiplier is a constant usually between 5 and 20 that is multiplied with the fsb to get the processor speed. As described at fsb If you have a fsb of 266 and a multiplier of 10 (That's with an amd 3800+) you'd get a 2,6 Ghz processor. You used to be able to change the processor but AMD and Intel locked them. Sometimes you still can change it by drawing a pencil line on a certain circuit.   Software Terms  N nibble   A nibble consists of four bits. A four-bit data field is capable of holding any one of sixteen values.   Software Terms  O o/s   o/s stands for Operating System.   Software Terms  P pci Peripheral Component Interconnect A high-speed connection for devices including SCSI cards, video cards,sound cards, modems, video capture cards, etc. This is the primary way of adding devices to your computer. It is faster than ISA, so is preferred for devices such as sound cards and SCSI cards. It is slower than AGP which is for graphics cards only, so AGP graphics cards tend to be better than PCI ones. Default PCI speed is 33 MHz.   Hardware Terms propagation   when a new domain name is registered (or an existing one is transferred to a new DNS), the information must make its way around the entire internet. This process usually takes around 24 hours, during which time the domain will be inaccessible to many or all users.   Internet Terms psu psu is a Power Supply Unit. This is screwed into the case and provides power to the mainboard and other components of the computer.   Hardware Terms  S sdram Synchronous dynamic random access memory delivers bursts of data at high speeds using a synchronous interface. Its is actually SDR SDRAM (single data rate SDRAM) but is usually used to referred to as just "SDRAM."   Hardware Terms  T terabyte   A terabyte is a SI-multiple (see prefix tera) of the unit byte for digital information storage and is equal to 1012 (1 trillion short scale) bytes or 1000 gigabytes. The unit symbol for the terabyte is TB.   Software Terms TLD A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space.   Internet Terms
