There are 2 type of devices:
end-user devices and network devices.
what are the network devices
Repeater: regenerate a signal.
* Hub: concentrate connections and may
regenerate a signal.
* Bridge: convert network transmission
data formats as well as perform basic
data transmission management.
* Switch: add more intelligence to data
transfer management.
* Router: routing and other services

two types of network topology
- The physical topology, which is the actual
layout of the wire or media. - The logical topology, which defines how the
media is accessed by the hosts for sending
data.
which is the actual layout of the wire or media.
- The physical topology,
, which defines how the
media is accessed by the hosts for sending
data.
The logical topology
are collections of protocols
that enable network communication from one
host through the network to another host.
Protocol suites
is a formal description of a set of
rules and conventions that govern a particular
aspect of how devices on a network
communicate.
