WEEK 4 - SESSION 3

In this session, I have learned about types of network.

Nowadays, people use LAN (Local Area Network) and WAN (Wide Area Network) in common. Let’s find out about it.

LAN: is a network in small geographical area such as: room, building, campus, ... It has two types:

·        Intranet: is a private LAN designed for use by everyone within an organization. Access to an intranet’s wed site is restricted by a firewall.

·        Extranet: is a network that connects people your company with people who are outside your company-all within a secure, password-protected network that can be accessed from anywhere.

WAN is a network spread geographically (Country or across globe). It has several types:

·        Metropolitan area network (MAN)

·        Public access network (PAN)

·        Value added network (VAN)

·        Virtual private network (VPN)

I also have known about Peer-to-Peer network, Server-Based network, its advantages and disadvantages, Client/Server network and the other types of network.

 

It is the end of this week. See u in the next post!
