In today’s interconnected world, local area networks (LANs) play an instrumental role in facilitating communication and data sharing within a confined space. A LAN is a computer network that spans a small area, typically within a single building or campus. It enables computers, servers, printers, and other devices to connect and communicate with each other, fostering efficient collaboration and resource sharing. LAN connection types and uses vary widely depending on the specific needs and infrastructure of an organization or individual. Exploring these connection types and uses in more detail can provide valuable insights into how LANs enhance productivity and connectivity in various settings.
Currently, on all desktop and laptop computers, LAN connections are supported. Have you ever wondered what LAN is?
What is LAN?
LAN stands for Local Area Network, roughly translated as local computer network , this interface allows computers to connect to each other to work and share data . This connection is made via a LAN cable or Wifi (wireless) in a narrow space, so it can only be used in a limited range such as offices, homes, schools…
What is the LAN port (RJ45) on computers and laptops?
Before diving deeper into LAN connection. Let’s talk a little bit about the name “LAN port” on laptops today. Because wireless connectivity was introduced and popularized long after wired (cable) connections, people often call the RJ45 (Ethernet) network cable connection port on laptops and computers as “LAN port” or “LAN port”. “ .
Currently, when it comes to connecting to the internet on laptops, our computers have two types: wireless connection via wifi and wired connection via network cable via RJ45 port or LAN port.
Types of connections in LAN
As mentioned, devices in the same LAN can connect to each other through a network cable. LANs can connect to each other to form a larger network called WAN (Wide Area Network) and to communicate with each other, devices are usually connected to one or several wifi routers (Routers). .
In addition, a LAN can also be established by a wireless connection port (Wireless) and is collectively known as WLAN (Wireless LAN) , or we often call it Wifi.

What are the requirements to create an internal LAN connection?
To create an internal LAN , a device is required as a server (sever), a number of devices that support connection and finally, clients .
Before creating a LAN, make sure that all devices have a built-in NIC (Network Interface Card) network card . The network card is considered a network signal transceiver for devices that want to connect to the LAN, the network card is usually built into laptops, computers, etc.
Uses of LAN
LAN has great significance in modern life today, any company, organization or individual who wants to manage internal data, or connect and communicate with each other must be through LAN.
LAN helps mobile devices such as phones, laptops, tablets easily connect and access the internet at any time.

The above is very basic and useful knowledge, please contact Tnhelearning.edu.vn about problems or problems arising in the process of accessing and using LAN connection on your technology devices to get help. please support.
In conclusion, Local Area Network (LAN) is a network infrastructure that allows connected devices within a limited geographical area to communicate and share resources. LAN connection types include Ethernet, Wi-Fi, and token ring, each offering its own benefits and limitations. Ethernet is the most widely used LAN connection type, providing high-speed and reliable wired connections. Wi-Fi, on the other hand, enables wireless connectivity, allowing for increased mobility. Token ring networks are less common nowadays but can still be found in certain specialized settings. LANs have various uses, such as facilitating file sharing, connecting devices within a home or office environment, accessing the internet, and enabling online multiplayer gaming. LANs are crucial in improving productivity, promoting collaboration, and enhancing communication among connected devices.
