Question

What is a Local Area Network (LAN)?

Options

• AA network that connects distinct geographical locations
• BA network that typically connects a single floor or building
• CA network that typically interconnects switching equipment
• DA network that connects two computers

Explanation

A local area network (LAN) is a network that typically connects devices within a limited geographic area, such as a single floor or building (see ISC2 Study Guide, Chapter 4, Module 1). For example, in a corporate office, a LAN might be used to connect all the computers, printers, servers, and other devices in the same building. This allows for efficient resource sharing, file sharing, and communication between devices on the network. As for the other choices, a network that connects different geographic locations is called a wide area network (WAN), not a LAN. A network infrastructure that connects switching equipment is typically called a Metropolitan Area Network (MAN). Such networks are larger than LANs but smaller than WANs, typically spanning a city or campus. A very simple network setup where only two computers are directly connected to each other. This is often referred to as a point-to-point connection, not a LAN.
