A local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building.

What is a Local Area Network?
A local area network (LAN) is a computer network that traverses a somewhat small area. Majorly, the LANs are included in a single building or group of buildings. For greater speed and security, a LAN normally relies largely on cable connections, while mobile devices like laptops and smartphones frequently employ wireless connections.
LANs are usually built using Ethernet or Wi-Fi technology. Ethernet uses a system of cables and devices called hubs or switches to connect computers and other devices to the network. Wi-Fi uses wireless technologies such as infrared light or radio waves to connect devices without cables.
LANs can be used for a variety of purposes, including file sharing, printing, and gaming. They can also be used to connect to the internet or other wide area networks (WANs).
Advantages of LAN
- Increased productivity: With a LAN in place, employees can share files and printers, which can lead to increased productivity.
- Cost-effective: A LAN is usually less expensive to implement and maintain than a wide area network (WAN).
- Scalability: A LAN can be easily expanded as needed by adding more devices and components.
- Flexibility: LANs can be configured to meet the specific needs of an organization.
- Security: Since LANs are typically located within a single building, they are easier to secure than WANs.
Disadvantages of LAN
- Limited geographic range: The main disadvantage of a LAN is its limited geographic range which is typically restricted to a single building or campus.
- Performance issues: If too many devices are connected to the LAN, it can slow down the network speed for all users.
