Introduction to Networking

First and foremost, the idea of networking is actually as old as telecommunication where this can actually become evident through the times of the stone age. Want to see an example? 

Here's a situation:

Caveman A wants to invite Caveman B over a game of hurling rocks at each other, but they live too far from each other. In this case, in terms of communication, it is difficult for two of these cavemen to contact each other as during these days, communication was not in an advanced state, unlike this era. So, in your point of view, what are the options that could be taken in order to communicate with each other?

Well, some of it are:
  1. Caveman A to walk over at Caveman B's place.
  2. Get a bigger drum so that Caveman B would be able to hear.
  3. Ask Caveman C, who lives halfway between them to forward the message. 
So, as you readers can see, back in the olden days, communication was considered very difficult. However, for us nowadays, everything has become so easy for us especially in terms of networking. ^^

NETWORK : A collection of connected intelligent computing device or between two computers by direct cabling which is the basic network.

NETWORKING : The practice of linking two or more computing device together for the purpose of sharing data.

Basic Network : Connected by a cable to allow exchange of data. 
Next, I am going to introduce to you readers four new terms which are LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network) and last but not least, PAN (Personal Area Network). 

LAN or Local Area Network is actually confined to a relatively small area and are generally limited to a geographic area such as labs, schools and buildings.

WAN or Wide Area Network, on the other hand, connects to larger geographic areas such as Johor Bahru, Malaysia and also the World. This is actually more complicated if it is compared to LAN. Adding on, this type uses multiplexing in order to connect the local and metropolitan networks which is via hybrid network.

MAN or Metropolitan Area Network is a network that links user with computer contrivance in a geographic zone or region larger than LAN but smaller than WAN.

PAN or Personal Area Network is the join of information technology devices in the range of one single person, usually within the range of 10 meters. This particular type of network applies some pattern of wireless technology. WiMax, 3G and wireless broadband are examples of PAN.  


BRIDGE: A bridge device filters data traffic at a network boundary. It reduces the amount of traffic on a LAN by dividing it into two segments.

Routers: A device that forwards data packets between computer networks, creating an overlay internet work. A router is connected to two or more data lines from distinctive networks.

HUBS: A device for connecting multiple Ethernet devices together and making them act as a single network segment.

GATEWAYS: A gateway is a network point that acts as an entrance to another network.

In today's lecture, I think there were many new and different terms regarding network and telecommunication that was exposed to us. By posting into this blog, it could actually help me to understand thoroughly about the topic because I could search and discover myself a deeper meaning and explanation about this particular topic. 

Hope you readers enjoy reading this post. Till then! ^^
