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

2nd Note

Computer Networking!

Let's discuss what is network today!  ヽ(・∇・)ノ

Simply put, a network a compilation of links. Maybe for some, computer network  = internet.

Even I thought the same thing before.

Actually computer network is  a collection of COMPUTERS and  other HARDWARE DEVICES that are CONNECTED together to share  hardware, software, and data as well as to communicate with one  another.

 For example a computer being connected to a printer, is also a  network.  

Now let me put some listing of 

Network Classification and Network components

Network Classification

• LAN (Local Area Network)
• PAN (Personal Area Networks)
• WAN (Wide Area Network)
• MAN (Metropolitan Area Network) 

 Network Components 

1. Terminals, Workstations,
   Computers, and other devices
   (end nodes)
2.  Transmission Media ( for
   transmitting data and control
   signals)
3.  Software to control data transmission
4.  Network electronics ( intermediate devices
   for routing data from source)
5. Network Architecture Standards
   (Standards to enable devices made by
   different companies to work/communicate
   with each other.
