According to the University of Colorado at Boulder, the Internet is a vast network connecting computers around the world through more than 750,000 miles (1,200,000 kilometers) of cables running over land and under water.
It is the fastest means of communication on the planet, allowing data to be transmitted from London, UK to Sydney, Australia in just 250 milliseconds. The creation and operation of the Internet was a remarkable achievement in technology.
What is the Internet?
The Internet is a vast network of computers that connects billions of devices via underground and underwater fiber-optic cables. These cables link continents and islands all over the world except Antarctica.
According to Science magazine, each cable is made of glass fibers that transmit data as light signals. These fibers are protected by layers of insulation and buried under the seabed using special equipment. This protects them from corrosion and even shark bites.
When you use the Internet, your computer or device sends requests through these cables, asking for access to information stored on other devices. Most people who connect to the Internet use the World Wide Web.
The Internet can connect us with people all over the world. When was the Internet invented?
It was originally created by the U.S. government during the Cold War. In 1958, President Eisenhower created the Advanced Research Projects Agency (ARPA) to advance the nation's military technology, according to the Journal of Cyber Policy. Scientists and engineers developed a network of interconnected computers called ARPANET.
The basic idea of ARPANET was to connect two computers in different locations, allowing them to exchange data. That idea became a reality in 1969, according to historian Jeremy Norman. Over the following years, the team connected dozens of computers, and by the late 1980s, the network included more than 30,000 machines, according to the UK Science and Media Museum.
