A group of computers connected through a secure and reliable network confined to a single area is known as a/an?

Cloud
LAN
Portal
WAN

The correct answer is: LAN

The correct designation for a group of computers connected through a secure and reliable network confined to a single area is a Local Area Network (LAN). A LAN is designed to facilitate communication and resource sharing among computers within a limited geographic scope, such as a home, office, or building. It typically employs high-speed connections and can include various types of devices, such as personal computers, printers, and switches, allowing them to interact effectively. In contrast, the other terms have different definitions. A cloud refers to off-site servers that store and process data accessed via the internet, not limited to a specific area. A portal is an access point that provides entry to a system or resource, which doesn't directly describe a network configuration. A Wide Area Network (WAN) spans larger geographic distances, connecting multiple LANs or other networks across cities or even countries, and is not confined to a single area, making it distinct from a LAN. Understanding these definitions helps clarify why LAN is the appropriate choice for this scenario.
