A. A local area network (LAN)

Explanation:

A local-area network (LAN) is a computer network that interconnects computers within a relatively small area. Most often, a LAN is confined to a single room, like your question, employees in a single office. LANs can be connected to other LANs over any distance via telephone lines and radio waves. and is called a Wide area network (WAN), the Internet is just one big WAN.

The major difference between a LAN and WAN is that the wide-area network spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs) and are often connected through public networks.

Most LANs connect workstations and personal computers. Each node (individual computer) in a LAN has its own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN.

All employees in the office have computers and these are called nodes. each node in a LAN has it's own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN. This means that many users can share expensive devices, such as scanners, laser printers, as well as data. Users can also use the LAN to communicate with each other, by sending email or engaging in chat sessions.

The nodes in a LAN can be hardwired or wireless, to set up a LAN you require a Network Switch but if you want the office to have access to the internet too a Router is a necessity.
