Communication protocol
Conventions or rules used by a program or operating system to communicate
between two or more endpoints.
Although many communication protocols are used, they all allow
information to be packaged, sent from a source, and delivered to a
destination.
NetWare Services breaks information to be communicated into blocks called
packets. In addition to data, each packet contains control information that
can be used for addressing, error checking and other purposes.
Communication protocols govern how the control information is presented.
When multiple protocols are used in a packet, “enveloping” or
“encapsulating” is used to place control information at the beginning and
sometimes at the end of the packet. Control information for the highest level
protocol is placed closest to the data and information for the lowest level
protocol is placed furthest from the data.
There are seven main communication protocols specific to NetWare:
Compare right
A property right that grants the right to compare any other value to a value of
that property.
