There are
2 types of Transmission Media in Networking used in Networking
1. Wired
(Cables)
2. Wireless
(Air)
In this
session we will cover, the wired part of the Transmission Media in
Networking. There are three types of wired transmission media,
1. Coaxial cables
2. Twisted
pair cables
3. Fiber optic cables
Coaxial
cables:
A coaxial
cable or coax is a cable, is used in the transmission of audio, video and
communication. Mainly coaxial cables are used network and broadband cable.
These cables have high bandwidths and greater transmission capacity.
The adjacent figure is of a commonly used coaxial cable. As shown in the figure these cables have a metal male connector end that is screwed onto a female connector.

The
Coaxial cables are two types:-
1) Thicknet
(10Base5)
2) Thinnet (
10Base2)
Thicknet, also known as Thick Ethernet or 10Base5.
Thinnet also known as Thin Ethernet or 10Base5, are antiquated Ethernet
networking technologies.
Both technologies use coax that consists of solid copper core surrounded by an insulater. 10Base2 is known as cheper net, thin Ethernet, thinnet, and thinwire which is a variant of Ethernet that uses thin coaxial cable, terminated with BNC connectors. Here 10Base2 means

- 10 Mbps
speed,
-
Baseband signals and
- 200
metres length (actual usage is 185 metres).
And, 10BASE5 is known as thick Ethernet that as the first commercially available variat of Ethernet. Here 10Base5 means
- 10 Mbps
speed,
-
Baseband signals and
- 500
metres length.
Understanding
the Thinnet and Thicket concepts into Transmission Media in
Networking

The number 10: At the front of each
identifier, 10 denotes the standard data transfer speed over these media- ten
megabits per second ( 10Mbps).
The Word Base: Short for BAseband, this part of the identifier
signifies a type of network the uses only one carrier frequency for signalling
and requiress all network stations to share its use.
The
segment type or segment lentgh: This part of the identifier can be a digit or a
letter:
Digit: shorthand for how long (in metres) a cable segment may be before
attenuation sets in. For example, 10Base5 can be no more than 500 meters long.
Letter: identifies a specific physical type of cable. For example, the T
at the end of 10BaseT stands for twisted-pair.
