Question

The Internet is a _______.

1. Local Area Network (LAN)
2. Mobile Area Network (MAN)
3. Storage Area Network (SAN)
4. Wide Area Network (WAN)

Answer 1

Correct Answer - Option 4 : Wide Area Network (WAN)

The correct answer is ​Wide Area Network (WAN).

• A global system of interconnected computers, using a standardized Internet Protocol suite for communication and sharing information is called the Internet.
• World Wide Web or ‘www’ is a collection of web pages that can easily be published on the Internet and read by millions of its users. 
• The first development was the introduction of host-to-host network interactions.
• This was first observed in ARPANET in 1969.
• It was developed by the Advanced Research Projects Agency (APRA) of the Department of Defence, U.S. It was one of the first general usages of computer networks.

• A personal area network, or PAN, is a computer network organized around an individual person within a single building. This could be inside a small office or residence.
• A typical PAN would include one or more computers, telephones, peripheral devices, video game consoles, and other personal entertainment devices.
• A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers.
• LANs can be built with relatively inexpensive hardware, such as hubs, network adapters, and Ethernet cables.
• A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus, or small region. A MAN is larger than a LAN, which is typically limited to a single building or site.
• Depending on the configuration, this type of network can cover an area from several miles to tens of miles. A MAN is often used to connect several LANs together to form a bigger network.
• When this type of network is specifically designed for a college campus, it is sometimes referred to as a campus area network, or CAN.
• A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN.
