Internet is the most recent technology that almost people around the world have been used.
It is a network of computers that offer access to people and information. People that used the internet is approximately about 100 million within a few years. Internet can be used in variety of industry that made people work become easy and we can do a lot of things with computers.It is a "network of networks" that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber optic cables, wireless connections, and other technologies.

Internet was first invented by the U.S military in mid-1960s. Thay wanted to develop a a network that can survive if one of the computers on their network didn't because their network was in area that is critical when a network can be shut down by a single computer's malfunction that is of course a major vulnerabilty.Then in 1970 the Advanced Research Project Agency(part oft the Department of Defense) set up the first part of what would become the Internet.

Network can be classify by the geographic area they cover. These are 3 most common design; local area network (LAN), metropolitan area network (MAN), wide area network (WAN).

Local area networks or LANs are a computer network covering a small physical area, like a home, office, or small group of buildings, such as a school, or an airport. The key attribute of a LAN is its limited geographic scope, not the number of nodes that attached to the network.

Metropolitan area networks, or MANs, are large computer network usually spanning a city. They typically use wireless infrastructure or optical fibre connections to link their sites. MAN is optimized for a larger geographical area than a LAN, ranging from several blocks of buildings to entire cities. MANs can also depend on communications channels of moderate-to-high data rates. MAN maybe owned and operated by a single organization.

Wide Area Networks or WANs are a computer network that covers a broad area any network whose communications links cross metropolitan, regional, or national boundaries. WAN is a wireless network that uses routers and public communication links. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other locations.It reports that international circuits operating at speeds of 256 Kbps or 1 Mbps provide a 3 second response time to users at workstations anywhere in the world.

Question that anyone may could not answer..
Who actually own or run the INTERNET??

The answer are
1. Nobody
2. Lots of people

Every computer that is connected to the internet is responsible for its own part of the Internet.
