What is LAN?

It is virtually impossible to think in a world that is interconnected, since the way that currently things do require speed and security, and in these cases nothing better than a LAN, the best way to share all kinds of data between computers regardless of the distance between them.

LANs have been extended, since its inception, military and scientific, to encompass many areas, and today any institution such as a hospital or school has a LAN network to develop their tasks. However, these are not the only places where one is needed, since it is possible to use it even with a limited number of computers.

What is LAN 1

Basically, a Local Area Network (LAN), or better known by its name in Spanish “Local Area Network” is a network that connects one or more computers within a limited geography is in small areas such as offices, schools or hospitals, or even in the home, through hardware and software, and in order to share files , resources and even an Internet connection.

Currently there are two basic types of LAN: via cable, called connection over Ethernet, and which must be interconnected between if all the devices that constitute it through a device called a router, and the second via radio waves, called Wireless LAN or “WLAN”, allowing us to get rid of cables and costly and complicated installations.

What is LAN 2

A little story

As it would increase the need for use of computer systems at universities and research laboratories, also grew the need to share the result of the work done in these devices, and became more than apparent to be had to develop a way to interconnect them. That is basically the beginning of networks, from there up to Ethernet and then to the LAN and Internet.

The importance of a LAN in today’s world

Without a doubt, today’s world could not function without the help of a system that allows you to share data and resources through the distances, and at this point, LANs are practically spinal column where the world’s largest companies rely to carry out their activities, both local and international.

What is LAN 3

This is due mainly to the most significant feature of a LAN: the allow multiple computers to interface called for this case, nodes, in order to access data and resources that these store or have connected. This means that a computer can access documents as well as Printers, external drives and other devices and peripherals connected to these remote PCs enabling us to expand the range of tasks that we perform with our own computer.

However, this type of interconnection is limited to a specific range of location, and achievable despite the speeds to a LAN, the distance that can be traveled is relatively short, therefore, that mechanisms have been created that allow you to extend these distances to even other continents.
