associated with non-synchronous RAM, which must close one address bank before 
opening the next. 
 
Serial port: called as such because it transmits the eight bits of a byte of data along 
one wire, and receives data on another single wire (that is, the data is transmitted in 
serial form, one bit after another). 
 
SIMM (Single In-line Memory Module): formally the most common form of RAM 
for motherboards. They must be installed in pairs, and do not have the carrying 
capacity or the speed of DIMM modules. 
 
Sleep/Suspend mode: in this mode, all devices except the CPU shut down. 
 
SRAM (Static RAM): unlike DRAM, this type of RAM does not need to be refreshed 
in order to prevent data loss. Thus, it is faster and more expensive. 
 
SSI (Server System Infrastructure): an industry initiative intended to provide 
ready-to-use design specifications for common server hardware elements (chassis, 
power supplies, and racks) to promote and support server industry growth. 
 
Standby mode: in this mode, the video and hard drives shut down; all other 
devices continue to operate normally. 
 
Striping: see RAID 
 
UltraDMA-33/66/100: a fast version of the old DMA channel. UltraDMA is also 
called UltraATA. Without proper UltraDMA controller, your system cannot take 
advantage of higher data transfer rates of the new UltraDMA/UltraATA hard drives. 
 
USB (Universal Serial Bus): a versatile port. This one port type can function as a 
serial, parallel, mouse, keyboard or joystick port. It is fast enough to support video 
transfer, and is capable of supporting up to 127 daisy-chained peripheral devices. 
 
VGA (Video Graphics Array): the PC video display standard 
 
V-SYNC: controls the vertical scanning properties of the monitor. 
 
ZIF Socket (Zero Insertion Force socket):
 these sockets make it possible to insert 
CPUs without damaging the sensitive CPU pins. The CPU is lightly placed in an 
open ZIF socket, and a lever is pulled down. This shift the processor over and down, 
guiding into the board and locking it into place.
