SAN32M-1 Installation and Service Manual
basic unit of information capacity on a computer storage device.
Eight bits equals one byte.
Expressed as bits per inch (bpi), the number of bits that can be written
on one inch of track on a disk surface.
Abbreviated as ber. Ratio of received bits that contain errors to total
of all bits transmitted.
Abbreviated as bpi. Indicates the density of information on a hard
drive.
In S/390 mode, in a director or switch, the attribute that, when set,
removes the communication capability of a specific port. A blocked
address is disabled so that no other address can be connected to it. A
blocked attribute supersedes a dedicated or prohibited attribute on
the same address. Contrast with
nection. See

(1) An attaching device that connects two local area network (LAN)
segments to allow the transfer of information from one LAN segment
to the other. A bridge can connect the LAN segments directly by net-
work adapters and software in a single device, or can connect net-
work adapters in two devices through software and use of a
telecommunication link between the two adapters. (2) A functional
unit that connects two LANs that use the same logical link control
protocol, but may use different media access control protocols (T).
Contrast with router. (3) A device that connects and passes packets
