3rd Note

Transmission Media & Network Electronic Devices

Now moving on with my notes for Lil' Mistress, we've reached the 3rd note.

 

As the tittle suggested, we'll be going over transmission media & network electronic devices. 

This will be a short post going over description and example. These topics are rather easy, even though the terms used are seemingly complicated.

Transmission media is the object used to transmit data. 

So it's simply a topic that tells us what device is used for the said purpose.

 

Twisted pair

The physical media have 2 types:-

1. Bounded/guided *trough wiring

•  twisted pair
• coaxial



Fibre optic

• fibre optic

Coaxial

'

1. Unbounded/unguided *using wave length, radio signal, etc.

•  satelite communication
• microwave radio
• infrared signals

 Okay, next we'll go trough what is Network electronic devices...

• Devices that controls data transmission from
  sources to destinations
• Act as interface between different
  transmission media or communication protocol

example of these devices are:-

•  Hub 
• Router
• Switch
• Bridge
• Gateway

Well, that's all for the 3rd. The 4th note will be about  network software. So be sure to come over for a review again. ヽ(・∇・)ノ
