MCQ
Q.
The Internet is a _______.
Correct Answer: D
The correct answer is Wide Area Network (WAN).
Key Points
- 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.
Important Points
- 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.
