 peer-to-peer.
In a peer-to-peer architecture, two or more nodes can
directly initiate communication with each other; they do
not need an intermediary. A device can be both the client
and the server.
P List
SCSI Term. This list contains the position of
all the defects which were found before the disk left the
factory and is stored in the system area of the disk. The
defective areas in the P list are the permanent defects
and accordingly must be reflected in the alternate block
allocation. Can be read with the READ DEFECT DATA
command. (0x37)
PR4ML
Partial Response class 4 Maximum Likelihood
P-ROM
Partial Read Only Memory
Only part of the optical disk is stamped with
unchangeable data, leaving the rest to be written to or
erased at will.
PC AT Interface
The extension bus for IBM personal computers and
their compatibles. The PC AT bus is a 16-bit data bus
supporting 24-bit address bus. The address bit of the
drive consists of 5 bits after decoding by the host
adapter.
PCA
Printed Circuit Assembly. Also known as Printed
Circuit Board (PCB)
Positioning Time
The total of the seek time and average latency
time.
Protocol.
A protocol is a standardized set of rules that specify
how a conversation is to take place, including the
format, timing, sequencing and/or error checking.
Pserver
A Novell NetWare printing service that takes a
print job and sends it to a printer assigned to that
queue. The adapter in PSERVER mode takes the place of
Novell PSERVER process and directs print jobs from a file
server queue to a printer attached to the adapter. Fujitu
printer ethernet interfaces can operate in pserver mode.
Pulse Code Modulation (PCM)
A method of sampling an analog signal that
results in a continuous code which is produced directly
from that signal. High resolution is possible with PCM,
due to the reduction of required pulses in the code.
