A local area network (LAN) is a group of computers and peripherals that share a common line of communication or wireless connection to a server in a specific area. A local area network can only serve two or three users in the home office or thousands of users in the company's head office. Homeowners and IT (IT) executives have set up LANs so that network nodes can communicate and share resources such as printers or network memory.
LAN requires Ethernet cable and Layer 2 switches as well as
devices that can connect and communicate over Ethernet. Larger LANs often
include layer 3 switches or a way to simplify traffic flow.
LAN allows users to connect to internal servers, web pages,
and other LANs that belong to the same broadband network (WAN). Ethernet and
Wi-Fi are the two main ways to enable LAN connections. Ethernet is a
specification of the Institute of Electrical and Electronics Engineers (IEEE)
that enables computers to communicate with each other. Wi-Fi uses 2.4 GHz and 5
GHz spectrum radio waves to connect computers to local area networks.

to create lan network using wifi
Abandoned LAN technologies, including the Fiber Distribution
Interface (FDDI) and the Connected Source Computer Network (ARCNET), have lost
their popularity as Ethernet and Wi-Fi speeds have increased and connection
costs have dropped.
Understanding the local area network
There are two main types of LAN: WLAN and WLAN.
LAN-connected LAN uses switches and Ethernet cables to connect Internet of
Things (IoT) endpoints, servers and devices to corporate networks. For small
businesses with very few devices, a LAN port can consist of a single
uncontrolled LAN switch with a sufficient Ethernet port to connect all devices.
But larger LANs, which connect thousands of devices, require additional
hardware, software, and setup steps to ensure the best network performance.
This is where the term virtual network (VLAN) comes into play.
