Question

what is one advantage of a local area network? it guarantees secure communications over the internet. the organization running the network can use all its own equipment. it can cover many geographical locations, such as multiple cities or states. it can be used by schools spread out over a large city or metropolitan area.

Explanation:

A local - area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. One advantage is that the organization running the network has control over the equipment used. It doesn't guarantee secure Internet communications (that's more about firewalls and encryption on the Internet side). LANs are limited in geographical scope and are not meant to cover multiple cities or states. The option about schools spread out over a large area is more about the usage rather than a fundamental advantage related to the nature of LANs.

Answer:

The organization running the network can use all its own equipment.
