of bits per symbol is known.
Blade Server A Blade Server is a computer system on a motherboard,
which includes processor(s), memory, a network connection
and, sometimes, storage. The blade concept addresses the
needs of large scale data centers to reduce space requirements
for application servers and lower costs.
A typical application could be serving web pages. So along
with a Storage Blade they can be rack-mounted in multiple
racks within a cabinet together with common cabling,
redundant power supplies and cooling fans. Blades can be
added as required, often as "hot pluggable" units of
computing as they share a common high speed bus.
IBM Definition: Blade Server refers to a chassis that can hold
a number of hot-swappable devices called blades. That is, the
entire package of chassis, server blades, and option blades.
Boot To start a computer so that it is ready to run programs for the
user. A PC can be booted either by turning its power on,
(Cold Boot) or by pressing Ctrl+Alt+Del (Warm Boot).
Break Signal A break signal is generated in an RS-232 serial line by
keeping the line in zero for longer than a character time.
Breaks at a serial console port are interpreted by Sun servers
as a signal to suspend operation and switch to monitor mode.
Checksum A computed value which depends on the contents of a block
of data and which is transmitted or stored along with the data
in order to detect corruption of the data. The receiving system
recomputes the checksum based upon the received data and
compares this value with the one sent with the data. If the two
values are the same, the receiver has some confidence that the
data was received correctly.
