Data and messages can easily be transferred over networked computers.

It saves a lot of time and money. LAN, MAN and WAN.

WLAN follows a standard named IEEE 802.11.

It mentions LAN advantages or benefits and LAN disadvantages or drawbacks.

The interference can be due to environmental problems like rain, thunder etc. In Net Cafes, single internet connection sharing system keeps the internet expenses cheaper. degree holder person optionally with a course / diploma in networking field or with relative experience in the field. A LAN Administrator may be with an M.C.S. Since, data is stored on server computer centrally, it will be easy to manage data at only one place and the data will be more secure too, because of more security for the server computer. wired LAN and Wireless LAN. Refer difference between Wired LAN uses 100BASE-T and 1000BASE-T standards. The data of all network users can be saved on hard disk of the server computer. These access points, manage network traffic which is flowing to and from the connected devices. In our home, school, office’s LAN, wireless broadband routers perform the functions of an access point.A typical Ethernet LAN consisting of an ethernet cable to which all the machines are attached, like in our school labs, number of computers connected to each other through the common et… It will cost more to purchase a separate licensed software for each computer in a network.

Wireless communication provides great flexibility. Covers Limited Area Local Area Network covers a small area like one office, one building or a group of nearby buildings. covers larger distances beyond walls and floors and uses IEEE 802.11 standards for implementation.

Among these types, LAN has lowest coverage upto 2 miles(or 2500 meters) and data rates (10/100/1000 Mbps). There may be file server on the LAN used for A typical Wi-Fi LAN operates one or more wireless access points that devices within coverage area connect to. LAN can be formed using just two computers connected together using network card or

User will access their own data by logging into their accounts from any client computer in the network.

Disadvantages of local area network (LAN) Data security problem: If the server computer is not set up correctly and there is a leak in security then unauthorized users can access the data also.

However wireless technologies are prone to interference and noise .

LAN in simple words can be compared to a toy train, just like a toy train has many coaches attached to it and it runs on track which is in round shape and it cannot go outside that track, similarly, LAN refers to that For example, a business organization using a Local Area Network for an office can use a single network printer for the employees of this office. multiple computers connected using Hub/Router. Wireless LAN is made by connecting different devices through wireless communication to make a local area network. A LAN Administrator is needed at this full time job. The networking are of two types viz.

There are two basic types of LAN viz. Wireless LAN uses radio frequency for transmission and Because only one high speed internet connection is purchased by a net cafe from any ISP - Internet Service Provider company.

Some companies discourage the use of in-house email because they believe that it is better for employees to communicate face to face. ©RF Wireless World 2012, RF & Wireless Vendors and Resources,

Introduction: The set of computers or devices connected together with the ability to exchange data is known as computer network. or B.S.C.S.

Local Area Network provides the facility to share a single internet connection among all the LAN users.
