What is LAN (Local Area Network)

LAN means Local Area Network, LAN (Local Area Network) is a network that adapts to the needs of small areas. It can be used at home, in offices, at airports and in small computer labs at the university. The idea of ​​the LAN device is to use fast data transfer in a small geographic area. LAN (Local Area Network) has been developed to provide better connections within each computer unit. Local area network (LAN) preferred because of its fast accessibility. LAN (local area network) is used to build an effective and sophisticated system for data exchange. What is LAN and how does it work, LAN Characteristics, LAN Applications and advantages are briefly explained below.

How LAN works

The first local area networks (LANs) were formed using coaxial cables, coaxial cables are electrical cables and are used to transmit radio signals. When you configure a local area network (LAN), two or more computers connected through a physical connection to share files and data over time. The primary application of this cable is to connect the radio transmitters to their antennas. However, it is also used to make Internet connections and distribute cable channels. The most common type of local area network (LAN) is Ethernet. Ethernet is commonly known as the primary technology for physical and data connection levels. Ethernet today can deliver the maximum data rate of up to 100 Mbps. Ethernet has proven to be a platform for Internet protocols. Usually, Ethernet cables extend to a length of 100 meters, but this is not the final limit. Ethernet cables can extend if necessary. If you want to develop a local area network (LAN), use special software such as Microsoft Windows. Microsoft windows offer special features for sharing on the Internet that support the local area network (LAN).

Wireless Local Area Network (WLAN)

The wireless connection that allows you to connect to your local area network (LAN) during transport is called a wireless or wireless local area network. The global trend of transporting and using laptops has reduced the use of traditional LANs. Also, office workers who own laptops often prefer Wi-Fi so they can do their homework while staying connected to their LAN. WLANs characterized by easy installation and wireless layout. The first WLAN was the ALOHA network, invented in 1970 by Norman Abramson. The wireless distribution system is a system in which many different access points connected without the Hassle cable. There are many types of WLANs. The WLAN can be a peer-to-peer network or an ad hoc network.

LAN Characteristics

LANs have several features that differentiate one LAN from another. The geometric location of the computer connected to a LAN referred to as network topology, refers to the way the devices connected to the network. The media function of a LAN refers to the physical connections of the devices to the network. Typically, devices connected to a LAN via coaxial cable, twisted pair cable, or fibre optic cable. The protocols of N/W regulate the specifications for sending data in the LAN. These protocols determine if the N/W is a client/server or a point-to-point LAN.

Client/server and point-to-point LAN

A client/server LAN, sometimes called a two-level LAN, consists of powerful computers,called servers, that manage disks, printers and network traffic. The clients in this type of LAN are the PCs or workstations that run applications. Peer-to-peer LANs, on the other hand, are networks in which each computer or node is equally involved in the operation of the LAN. Although point-to-point LANs are more comfortable to configure, they do not work as well under heavy load. Therefore, client/server LANs have been specifically designed for this purpose.

LAN application and advantages

Local area network (LAN) applications commonly used in universities, some banks, private homes and in some flight reservation systems. With LAN, you can store data on any central computer from which data can be shared throughout the company. File transfer and recovery is accessible on a local area network (LAN) because backup files stored on a single server. Restricted LAN PCs provide sufficient security for the data because only authentic users can share and access the data. With the local area network (LAN), you can save on installation costs for various software products by centrally managing and sharing resources. Besides, each device can use expensive hardware devices, such as laser printers, CD burners and scanners. User files can be accessed from different workstations. Sharing resources and hardware simply reduces the cost of using independent printers and scanners. This division reduces costs and increases productivity. The active physical backup system reduces the risk of data loss. Recover lost data with data recovery software costs you extra money. However, physical backup support also helps cover these additional costs.
