What is LAN?
The full name of LAN is Local Area Network, and a local area network (Local Area Network) is a network established to meet the needs of small areas. It can be applied to home, office, airport and small university computer room.
The idea behind developing a LAN is to use fast data transfer rates within a small geographical area. LAN (Local Area Network) was developed to create better connections between individual computer units. LAN (Local Area Network) is favored for its fast access and affordable price. LANs (Local Area Networks) are used to build successful complex networks to share data.
How LAN works
LANs (Local Area Networks) were originally formed using coax cable, coaxial cable is a type of electrical cable and it is used to transmit radio signals.
A LAN (Local Area Network) setup was developed by connecting two or more computers together using a physical connection to share files and data overtime. The basic application of this cable is to connect radio transmitters to their antennas.
However, it is also used to develop internet connections and distribute cable channels. The most popular growing LAN (Local Area Network) type is Ethernet. Ethernet is often referred to as the primary data and physical link layer technology. Ethernet is often associated with the name of engineer Robert Metcalfe.
Today’s Ethernet can provide a maximum data rate of up to 100 Mbps. Ethernet has proven to be an effective way to serve as a data transmission medium for internet protocols. Normally, Ethernet cables are extended to a length of 100 meters, but this is not the final limit. Ethernet cable can be extended according to need.
When you decide to develop a LAN (Local Area Network), try to use specialized software like Microsoft windows. Microsoft widgets provide special internet sharing features that help LAN (Local Area Network).
Wireless local area network (WLAN)
A wireless connection that allows you to connect to a LAN (Local Area Network) while you are on the go is called a WLAN or a wireless local area network. The worldwide trend of carrying and using laptops has reduced the use of traditional LANs.
Furthermore, office workers who own laptops often prefer WLAN, so they can work their office at home while they are still connected to their LAN. WLANs are admired for their ease of wireless installation and arrangement. The first wireless LAN was the ALOHA network, invented by Norman Abramson in 1970.
A wireless distribution system is a system in which various access points are linked without wires. There are many types of wireless LANs. A wireless LAN can be a peer-to-peer network or it can be an adhoc network.
Applications of LAN and Benefits of LAN
The application of LAN (Local Area Network) is widely used in universities, some banks, homes and some air reservation systems. A LAN allows you to store data on any central computer that can be shared across the organization.
Easily transfer and restore files within a LAN (Local Area Network), as backup files are stored on a single server. PCs in a restricted LAN provide adequate security for data as only legitimate users can share and access data. Centralized management and sharing of LAN (Local Area Network) resources saves you the installation cost of various software equipment.
In addition, expensive hardware devices such as laser printers, CD recorders and scanners can be used equally from each individual unit. User files can be accessed from many different workstations. Easy sharing of hardware resources and devices reduces the cost of using stand-alone printers and scanners. This sharing reduces costs and increases productivity.
The risk of data loss is minimized thanks to an efficient physical backup system. Restoring lost data with the help of data recovery software incurs additional charges. However, supporting physical backups can also help offset this additional cost.
What is an intranet?
A network that uses Internet Protocol technology to share any type of information within a business association or company is called an intranet. So we can say that the intranet is an internally protected business environment. The phrase is used in contrast to the Internet. An intranet is a network between associations and can also be part of an organization’s information expertise. An intranet can consist of multiple websites and is an important part of partnerships and internal communications. The intranet supports the human resources department, sales department, accounting department, and information system. The main contents of the intranet are as follows.
Intranet overview
The intranet uses the same concepts and technologies as the Internet, such as TCP/IP, client server, etc. Various well-known protocols are used for intranet technologies, such as FTP, HTTP, and SMTP. The goal behind implementing the Internet was to provide modern interfaces to information systems that store business data.
An intranet, also known as a private analog network of the Internet, is limited to an organization or association. During 1990-1991, the most important intranet home page became visible.
Early users of intranet technology were corporations and universities. Contrast an intranet with a perimeter network, which is typically controlled by employees of any business company, but off-site networks can also access suppliers, customers, and others.
External networks extend private networks on the Internet with unusual requirements for access, approval, and verification. The Internet provides a gateway to the Internet with a useful firewall that protects the internal network from unauthorized access from the outside.
