Word Definition
Flash Memory
Flash memory is a form of EEPROM that allows multiple memory locations to be erased or written in one programming operation. Flash memory holds its content without the need of a power supply. The memory is commonly used in Memory cards, USB Flash drives, MP3 players, digital cameras and mobile phones. In some cases, a large flash device can be used instead of a disk drive. Although there is a theoretical limit to the number of times a flash memory can be erased and rewritten successfully, this limit is seldom reached in practice.
Flatbed Scanner
Flatbed scanner is a popular type of scanner for home use, which works when an original is placed face-down on a sheet of glass and an arm equipped with a light and an electronic sensor sweeps under the glass. Flatbed scanners are particularly effective for bound documents.
Flat-Panel Display
Flat panel displays encompass a few technologies enabling video displays that are lighter and much thinner than traditional television and video displays using cathode ray tubes. The flat panel display echnologies include: Plasma displays, Digital light processing (DLPs), Liquid crystal displays (LCDs), Organic light-emitting diode displays (OLEDs), Field emission displays (FEDs), Liquid crystal on silicon (LCOSs), Surface-conduction Electron-emitter Displays (SEDs), Nano-emissive display (NEDs).
Flip-Flop
In the context of computer circuits, flip-flop is also called as a bistable gate. It is a type of circuit that is interconnected with like circuits to form logic gates in digital integrated circuits, such as memory chips and microprocessors. The name flip-flop comes from the circuit nature of alternating between two states when a current is applied to the circuit. A flip-flop will maintain its state indefinitely until it receives an input pulse, called a trigger, which forces it to alternate its state. Once the circuit changes state it remains in that state until another trigger is received.
Floppy Disk
A floppy disk is a data storage device that is composed of a circular piece of thin, flexible (i.e. "floppy") magnetic storage medium encased in a square or rectangular plastic wallet. Floppy disks are read and written by a floppy disk drive or FDD. Unlike most hard disks, floppy disks (often called floppies or diskettes) are portable, because you can remove them from a disk drive. Floppy disks are slower to access than hard disks and have less storage capacity, but they are much less expensive.
FPM RAM: Fast Page Mode RAM
Fast Page Mode RAM (FPM RAM), also known as page mode memory, is a type of Dynamic RAM (DRAM) that allows faster access to data in the same row or page. Page-mode memory works by eliminating the need for a row address if data is located in the row previously accessed.
FPU: Floating Point Unit
A floating point unit (FPU) is a part of a CPU specially designed to carry out operations on floating point numbers. Not all CPUs have a dedicated FPU. In the absence of an FPU, the CPU may use a microcode program to emulate an FPUs function using an arithmetic and logical unit (ALU). Computers equipped with an FPU perform certain types of applications much faster than computers that lack one. In particular, graphics applications are faster with an FPU.
Framebuffer
The framebuffer is a part of RAM in a computer allocated to hold the graphics information for one frame or picture. This information typically consists of color values for every pixel (point that can be displayed) on the screen. Typically the frame buffer is stored in the memory chips on the video adapter. In some instances, however, the video chipset is integrated into the motherboard design, and the frame buffer is stored in general main memory.
FSB: Front-Side Bus
Front-Side-Bus (FSB), also known as CPU bus, memory bus and system bus, is the bus between Processor (CPU) to system memory. The front side bus on a computer connects the processor to the north side bridge, which comprises the memory bus, PCI bus and AGP bus. In general, a faster frontside bus means higher processing speeds and a faster computer.
FTTC: Fiber-To-The-Curb
Fiber-To-The-Curb (FTTC) refers to the installation of optical fiber from a telephone switch of service provider to a home or enterprise, as a replacement for "plain old telephone service" (POTS) using wire. Optic fiber wiring would provide extremely high bandwidth and make possible movies-on-demand and online multimedia communications.
