What is a local network? How to create and configure a local network

Due to the fact that the number of Internet users is constantly growing, and the development of computer and information technologies is accelerating, it became necessary to solve a huge amount of tasks that are associated with the reception and transmission of data. That is why it became necessary to create local area networks. After all, LAN is the technology of the future that is available today.

A local area network is such systems that include various elements integrated with each other: how much do network administrators make

Structured Cabling System (SCS)
Server
Network devices (switches, repeaters, gateways, access points)
Workstations (End User Computers)
Office equipment (Printers, scanners, MFPs)
And may include:

Channels of connection
VPN
Various media equipment (videoconferencing, projectors, televisions and panels)
Moreover, they can be located not only in the same room, but also at a considerable distance from each other. Networks can be wired or implemented wirelessly. They are designed to combine computer technology into a single network used for data transmission.

Basic properties of local area networks

Local networks are characterized by such properties as scalability, flexibility, fault tolerance, reliability, protection and manageability. These properties are the main characteristics of a LAN.

The first property is necessary for the possibility of increasing the expansion of the network, without its radical restructuring (with minimal architectural costs).

Flexibility allows you to quickly respond to new technologies and adapt to different types of cable connections or wireless network options.

Fault tolerance shows the stability of the LAN, in the event of failure of its individual nodes. For this, the systems of local networks must have backup lines, spare nodes that can be used if the main networks fail.

Reliability shows that the local network will work as long as possible, even when the company's needs increase, the load increases, and downtime can be too expensive for the organization.

A very important property is protection, which makes it possible to ensure the security of the network from any unauthorized access and external attacks.

Manageability implies that local networks must have good monitoring tools that help quickly identify various interference and malfunctions. Thanks to this, downtime and various unforeseen moments that affect the efficiency of the company are almost completely eliminated.

The main tasks of local area networks are to implement shared access for each user to various data, programs and devices. This will provide users with simultaneous access to the necessary operations. In addition, local lines will allow you to process and store data, transfer information results to clients, monitor the implementation of projects and many other functionality.

The main components of the local network

A local computer network cannot fully function without special equipment. The main components of such a network are passive equipment (switching panels, wiring closets, sockets, cables and cable channels), active equipment, which are routers, switches, all kinds of media converters. They are also peripheral devices (printers, servers, scanners) and computers, laptops, tablets and mobile devices.
