I think before concluding the TITLE , we must have a good understanding about LAN( Local Area Network ) and WAN( Wide Area Network ). So let’s move towards it.

Both LAN and WAN are networking types and networking is sharing resources and communicating via a set of common path by group of computers.

About LAN:

LAN stands for Local Area Network and as its name suggest its meaning, it is computer network that interconnects computers within a limited area such as a residence , school , office buildings ,university campus.

LAN is often owned by private organizations. LAN speed is quiet high.

Advantages and Disadvantages of using lan:

Advantages:

  1. It provides flexibility to share costly equipment. For e.g 4 PCs can share same laser printer and file server which are expensive hardware.

2. Data and messages can be easily shared with the other computer which are connected to the network.

Disadvantages:

  1. Setting up of LAN is quite expensive as it requires special software and equipment like router,cables,switches,hubs and it also requires administrator to look after the problems like software installation,hardware failures,etc.
  2. Data security threat is at its peak.Any unauthorized user can access our data if a server is not properly secured.
  3. As LAN covers a limited area,sharing of information cannot be done at distant places.

About WAN:

WAN stands for Wide Area Network . It is a telecommunications network that extends over a large geographic area for the primary purpose of computer networking. WAN is countrywide and worldwide network.

WAN ownership can be private or public. WAN speed is lower than that of LAN.

“Every LAN may or may not be with WAN, but every WAN will be with LAN”

Let’s see an example to get a good idea about it. Suppose a student want to access his/her college site.He/She can access it within the college campus using LAN but if they want to use it out of college campus then, they need a WAN network which connects them to the college LAN network.

LAN connects the local devices to each other whereas WAN connects LANs to each other, usually across multiple locations as well as individual devices that connect from a remote distance. Hence every LAN may or may not be with WAN, but every WAN will be with LAN.
