What are the advantages and disadvantages of a WAN?

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
• large network cover

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

Occupants in two buildings can share a wireless connection to a network such as a large corporate network that demands connectivity. But a disadvantage is that the signal is strong enough for anybody passing by to use for their own benefit without paying. You may have internet service flowing through your house on a wireless router and your neighbor may creep up close to your house and share your internet connection with you. So without security this technology is a blessing and a curse at the same time
