Introduction to WAN:
A wide area network (WAN) is considered to be a geographically distributed private telecommunications network that would be interconnecting multiple local area networks (LANs). In an enterprise, a WAN might be consisting of connections to a company’s headquarters, branch offices, collocation facilities, cloud services as well as other facilities.
Introduction to LAN:
A local-area network (LAN) is considered to be a computer network that would be spanning a relatively small area. Most often, a LAN would be confined into a single room, building or group of buildings, however, one LAN would be able to connect to other LANs over any distance via lines of the telephone as well as radio waves.
Difference between LAN and WAN
A computer network simply means any set of computers and other devices such as smartphones, smart TVs, video game systems as well as routers that would be able to communicate back and forth with each other. Different protocols, or rule systems, which would be existed that let computers which would be understanding each other and transmit data.
A LAN, or local area network, is considered to be a small network, often within a home or business or perhaps within a larger environment such as a corporate office park or a college campus. Devices on a LAN could often be utilized by the LAN’s infrastructure to connect to the public internet, but they could often communicate with each other directly through the LAN more rapidly. For instance, it isn’t usually necessary to send a file to the public internet to get it to a printer on the same LAN. A LAN could use wireless communication, wired connections or maybe both.
A wide area network frequently traverses multiple geographical areas. The internet is considered to be the most prominent example of the WAN network type, though other wide area networks would have existed for scientific purposes, military as well as government work and to connect far-flung offices and data centers within some major corporations.

The Advantages of LAN
Following are considered to be the advantages of LAN:
- The basic LAN implementation doesn’t cost too much.
- It would be easy to control as well as manage the entire LAN as it would be available in one small region.
- The LAN configuration is very easy due to availability of required protocols in the Operating System (OS) itself.
- The systems or devices which would be connected on LAN communicate at a very high speed depending upon LAN type as well as Ethernet cables supported. The common speeds which would be supported are 10 Mbps, 100 Mbps, and 1000 Mbps. Gigabit ethernet versions would be evolving very fast. Cheaper versions would be available once the technology matures as well as mass production has been carried out.
- With the help of file servers which would be connected on the LAN, sharing of files and folders among peers would become very easy and efficient.
- It is considered quite easy to set up security protocols to protect the LAN users from intruders or hackers.
- It would be easy to share common resources like the printers and internet line among multiple LAN users.
- LAN users wouldn’t require their hard-disk and CD-ROM drives. They could save their work centrally on a network file server.
Thus, if you are still pursuing the CISCO Certification and want to learn more about the LAN, you could have it through the SPOTO Online Training Certifications. They are the best when it comes to IT Certification Training.
