Media type

What is a media type example?
Media type is a pathway which is use to communicated from one computer to ano6 computer. Media is considering in two media type.


  1. Trusted media
  2. Untrusted media

  • Trusted media

It consist a cable and it is responsible 100% transfer the data.

Cables:-

Type of cables:-
  1. Twisted pair utp and stp
  2. Co-axial
  3. Fiber optic

Twisted pair:-

Twisted pair consist two types,
  1. STP (shielded twisted pair) cable
  2. UTP (unshielded twisted pair) cable
STP:- STP is use for underground fitting.

UTP:- UTP is used for open.

UTP is consisting of following color code:-

 Orange white
 Tx
 Orange Tx
 Green white Rx
 Blue white 
 Blue 
 Green Rx
 Brown white 
 Brown 

Type of UTP cables:-

Cat 1: use audio for telephone and its dtr is 4 Mbps.
Cat 2: use for computer network and its dtr is 8 Mbps.
Cat 3: use for computer network and its dtr is 16 Mbps.
Cat 4: use for computer network and its dtr 20 Mbps.
Cat 5: use for computer network and its dtr 100 Mbps.
Cat 6: use for computer network and its dtr is 100 Mbps to 1 Gbps.

Using the UTP cables we are to create various cable type to connect various devices.
  1. Straight through:- it is used for to connect dissimilar types of device. Like hub to pc, switch to pc, switch to router.

2. Cross over cable:- it is use to connect similar type of device like pc to pc, hub to hub, switch to switch.

3. Roll over:- it is use to connect router to computer it is also called console cable.

Cable specification:-

 Gigabit 1000 base t 1 gtps baseband twisted pair
 Fast ethernet 100 base t 100 Mbps baseband twisted pair
 Ethernet 10 base t 10 Mbps baseband twisted pair

Co-axial:-
What is a media type example?

It is mostly use for TV network. This cable is available in,
10 base 2 10 Mbps speed distance 200m
10 base 3 10 Mbps speed distance 300m
10 base 5 10 Mbps speed distance 500m

Fiber optic:-
It is one the best cable to transmit the data audio and video to long distance networking. It is very expensive and complicated to manage.

Specification:-
1000 base LX long wavelength, multimode[3 km] or single mode [100 km]
1000 base sxshort wavelength,
10 base F 2000 meters

Fiber optic mode:-
  1. Multi-mode used LED used in LAN's
  2. Single mode used laser used in telephone network

Connectors:-
  1. SC (subscriber connector)
  2. ST (straight tip connector)
Ethernet: any network is configuring using twisted pairfiber optic cable is called ethernet.
Token ring: any network is configuring using co-axial cable is called token ring.

  • Untrusted media:-

It consist to wireless frequency and it is not secure to transfer the data 100%.
