FC-PGA (Flip Chip-Pin Grid Array)
FC means Flip Chip, while FC-PGA is a new package of Intel for Pentium
III CPU. It is compatible with SKT370 socket, but requires mainboard to
add some signals on socket 370.
Flash ROM
Flash ROM can be re-programmed by electronic signals. It is easier for
BIOS to upgrade by a flash utility, but it is also easier to be infected by
virus. Because of increase of new functions, BIOS size is increased from
64KB to 256KB (2M bit) or more.
FSB (Front Side Bus)
FSB is the data channel connecting the Processor to chipset, RAM, mainboard
buses, AGP socket etc. Its speed is in terms of MHz and is talked to as FSB
clock:
FSB Clock means CPU external bus clock.
CPU internal clock = CPU FSB Clock x CPU Clock Ratio
IEEE 1394
IEEE 1394 is a low-cost digital transfer interface with transfer rate at 100,
200 or 400 Mbps. It provides solutions of connecting digital television devices
and Serial Bus Management. There are two type of IEEE 1394 data transfer:
asynchronous and isochronous. Isochronous data channels provide
guaranteed data transport at a pre-determined rate. This is especially
important for time-critical multimedia data where just-in-time delivery
eliminates the need for costly buffering.
Parity Bit
The parity bit mode of error detection uses 1 parity bit for each byte. Normally
it is even parity mode, that is, each time the memory data is updated, parity
bit will be adjusted to have even count “1” for each byte. Next time when
memory is read with odd number of “1”, the parity error is occurred and this
is called single bit error detection.
PC-100 DIMM
SDRAM DIMM that supports 100MHz CPU FSB bus clock.
PC-133 DIMM
SDRAM DIMM that supports 133MHz CPU FSB bus clock.
