Still Components Of a Network

You Guessed it, By Kyle Hofberg

LAN

A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media.[1] The defining characteristics of LANs, include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

WAN

A Wide Area Network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and individuals for almost any purpose imaginable.

Advantages of WAN

Covers a large geographical area so long distance businesses can connect on the one network

Shares software and resources with connecting workstations

Messages can be sent very quickly to anyone else on the network. These messages can have pictures, sounds, or data included with them (called attachments).

Expensive things (such as printers or phone lines to the internet) can be shared by all the computers on the network without having to buy a different peripheral for each computer.

Everyone on the network can use the same data. This avoids problems where some users may have older information than others.

Share information/files over a larger area

Disadvantages of WAN

Are expensive and generally slow

Need a good firewall to restrict outsiders from entering and disrupting the network

Setting up a network can be an expensive and complicated experience. The bigger the network the more expensive it is.

Security is a real issue when many different people have the ability to use information from other computers. Protection against hackers and viruses adds more complexity and expense.

Once set up, maintaining a network is a full-time job which requires network supervisors and technicians to be employed.

Information may not meet local needs or interests

Vulnerable to hackers or other outside threats.
