It Is All About Networking

In our 2nd class, we learn about Network Classification and Network Topology. When I learn about network classification, I get to know two more network types that are Wide Area Network (WAN) and Metropolitan Area Network. All this time I only know about Local Area Network (LAN), shame on me, huh? :(

Lets me tell you about these three types of network classification :

1) Local Area Network : 

- These connect over a relatively small geographical are, typically connecting computers within a single  office or building. In most cases they connect to a common electronic connection- commonly known as a network backbone.  LAN's can connect to other networks either directly or through a WAN or MAN. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.  Most LANs connect workstations  and personal computers .

2) Wide Area Network :
- These connect networks over a large geographical area, such as between different buildings, towns or even countries. A wide area network (WAN ) is a geographically dispersed telecommunications network . The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks.

3) Metropolitan Area Networks :

- These connect networks around a town or city. it is smaller than a WAN, but larger4 than a LAN. A data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs) , but smaller than wide-area networks (WANs) . MANs are usually characterized by very high-speed connections using fiber optical cable  or other digital media.

Enough with the network types, I would like you all to know about Network Topology. A small dialogue I created :)

Angah (Me) : Hey friends, let me introduce you to Network Topology.

Friends : Network Topology? Is it something or someone? *they were clueless...

NET. Topology : Hye all, I'm Net. Topology. Lets me tell all of you about myself, okay?

About Me (Network Topology)

- In computer networking, topology refers to the layout of connected devices. Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. 

- Network topologies are categorized into the following basic types :

      ~ bus

      ~ ring

      ~ star

      ~ tree

      ~ mesh 

Different types of network topologies

- Topologies remain an important part of network design theory. You can probably build a home or small business computer network without understanding the difference between a bus design and a star design, but becoming familiar with the standard topologies gives you a better understanding of important networking concepts like hubs, broadcasts, and routes.

Okay, THE END for the story of network topology and it also THE END for this entry. Thats all from me, hope all of you gain something new about networking. Do keep in touch, spread the word, spread the love, spread this BLOG... Merci beaucoup monsiuer et madamme moiselle :) *french language
