Local Area Networks (LANs) and Wide Area Networks (WANs) are two types of computer networks that have different characteristics and serve different purposes. LANs are designed to connect users and applications in close geographical proximity, such as within the same building. WANs, on the other hand, are designed to connect users and applications in geographically dispersed locations, such as across the world. The main objective of a LAN is to provide a higher quality service or a differentiated service to a smaller geographical area, such as a town, a city or a university campus.
It also establishes a connection between the various LANs it can serve and the WAN with which it can operate. Because LANs cover a much smaller geographical location than WANs, there is less chance of someone trying to damage the network or gain unauthorized access. This makes them more secure than WANs, which cover larger areas and are more vulnerable to malicious attacks. In conclusion, LANs and WANs are two different types of computer networks that have different characteristics and serve different purposes. LANs are designed for small areas while WANs are designed for larger areas.
Additionally, LANs are more secure than WANs due to their smaller geographical coverage.
