BASIC PRINCIPLES OF NETWORKING


BASIC PRINCIPLES OF NETWORKING

Communication Channels
a

pathway over which information can be
transferred
 information sent over a channel has a source
(transmitter), from which the information originates,
and destination (receiver), to which the information
is delivered

 Simplex
a

Channel

channel whose direction of transmission is unchanging

 Half–Duplex

Channel

a

channel in which the direction may be reversed, but the
transmission does not occur at the same time

 Full–Duplex

Channel

a

channel that allows simultaneous exchange in both
directions

DISTRIBUTED SYSTEMS


Client/Server

DISTRIBUTED SYSTEMS


Local Area Network (LAN)
 connects

network devices over relatively short
distances
 usually owned by an individual or corporation

 an

extension of distributed data processing wherein
it provides the best of both centralized and
distributed data processing


Wide Area Network (WAN)
 spans

a large physical distance (geographicallydispersed collections of LANs)
 not owned by any one organization but rather exist
under collective or distributed ownership and
management
