What does local area network mean? What does LAN mean?

The concept of local area network:

There are many ways to communicate in the computer field. Some communication methods are used locally, such as SCSI equipment, and have a distance limit (5 meters). Other communication methods, such as two systems talking to each other over a network, can reach greater distances.

Today, networks are often divided into LAN and WAN based on the geographic extent they cover. The two main networks are:

Local Area Network (LANS) These network-connected devices are within a local range (no more than 5 km). A LAN is a data communication system that allows independent devices to communicate with each other. The limitations of the LAN are:

Private networks, which must be connected by a continuous medium, support both low-speed and high-speed data communication.

Wide Area Networks (WANs) These networks cover a large geographical area, and devices in one city can communicate with devices in another city, and the WAN covers a larger geographic area.

Both types of networks are based on the same principle. And it's all about achieving the same goal, but with a lot of different techniques.

Your computer and other computers that access the Internet belong to the Wide Area Network (WANS), including Netcom and Tietong.

LAN is a computer local area network, which is a computer communication network composed of various computers, peripheral devices, databases, etc. connected to each other within a local geographical range, referred to as LAN. LAN is an important part of the computer communication network, in addition to completing the communication of one station to another, but also through the shared communication ** such as data communication network or dedicated data circuit, and the remote local area network, database or processing center connection, constitute a wide range of information processing system, its purpose is mainly in data communication and resource sharing.

If you're in school, it means being in the same school as you.

If you're in an internet café, it means being in an internet café with you.

It's the network in your city.

LAN, network type, coverage is generally within a radius of a few thousand meters, and its convenient installation, cost-saving, and convenient expansion make it widely used in various offices. In the process of use, by maintaining the security of the LAN network, it can effectively protect the data security and ensure the normal and stable operation of the LAN network.

Wired LANs use a variety of different transmission technologies. Most of them use copper wires as the transmission medium, but some use fiber optics as well. The size of the LAN is limited, which means that the worst-case transmission time is also bounded and can be known in advance.

Understanding these boundaries can help with the design of network protocols.

Typically, wired LANs operate at speeds between 100Mbps and 1Gbps with very low latency (microseconds or nanoseconds) and few errors. Newer LANs can work at speeds up to 10Gbps. Compared to wireless networks, wired LANs outperform them in all aspects of performance.

Dear, hello, the local area is a regional network formed in a local area, which is characterized by a limited range of distribution areas, which can be large or small, as large as a building to build a building and the connection between adjacent buildings, and the small shed can be the connection between offices. Compared with other networks, the LAN itself has faster transmission speed, more stable performance, simple framework, and is closed, which is why many organizations choose it. The composition of the LAN itself is roughly composed of computer equipment, network connection equipment, network transmission medium 3 parts, wherein, the computer equipment and Bao Shi and Song include servers and workstations, network connection equipment contains network cards, hubs, switches, network transmission media is simply the network cable, composed of coaxial cable, twisted pair and optical cable 3 major originals.

Summary. Hello dear<>

A LAN is an interconnection of multiple computers and network devices connected within a relatively small geographical area (such as a work, school, or home).

What does LAN mean?

Hello dear<>

A LAN is an Internet network of multiple computers and networks connected within a relatively small geographical area (such as a company, school, or home). Pickpocketing.

These devices are typically managed and controlled by the same organization or entity. LAN is characterized by fast transmission speed, safety and reliability, so LAN is often used for internal communication in the physical situation, such as data sharing between various departments within the company, or the interconnection between multiple computers and intelligent cave equipment in the family!

The communication environment established by the LAN is usually composed of a computer (server) and a number of client computers (workstations), which are connected by network equipment such as interface cards, hubs, switches, routers, etc. Usually a LAN is managed and maintained by only a few network administrators. <>
