Bus An electrical circuit which passes data between the CPU and the sub-assemblies inside your LifeBook notebook. Byte 8 bits of parallel binary information. Cache Memory A block of memory built into the micro-processor which is much faster to access than your system RAM and used in specially structured ways to make your overall data handling time faster. CardBus A faster, 32-bit version of the PC Card interface which offers performance similar to the 32-bit PCI architecture. CD-ROM Compact disk read only memory. This is a form of digital data storage which is read optically with a laser rather than a magnetic head. A typical CD-ROM can contain about 600MB of data and is not subject to heads crashing into the surface and destroying the data when there is a failure nor to wear from reading. Channel Range of narrow-band frequencies used by the WLAN device to transmit data. IEEE802.11b/g - 11 channels, 22 MHz wide channels. CMOS RAM Complementary metal oxide semiconductor random access memory. This is a technology for manufacturing random access memory which requires very low levels of power to operate. 142 -
