Global network of billions of computers and other electronic devices were known as the Internet. By using Internet, information can be reach, communication around the world, and do much more.

How? We just need to connect a computer to the Internet. When someone says a computer is online, it’s just another way of saying it’s connected to the Internet.

After got connected, we can access and view websites, using a type of application known as web browser. Ups! Web browser is not Internet; it only displays websites that are stored on the Internet.


  • As global network of physical cables, Internet can include copper telephone wires, TV cables, and fiber optic cables.
  • Even wireless connections (Wi-Fi, 3G/4G) rely on these physical cables to access the Internet.
  • During website’s visit, computer sends a request over these wires to a server.
  • A server is where websites are stored, and it works a lot like your computer’s hard drive.
  • Once request arrives, server retrieves the website & sends the correct data back to computer.


  • Can communicate almost instantly with people around the world.
  • Email is universal ways to connect and share info, and billions of people use it.
  • Social media allows people to connect in a variety of ways and build communities online.
  • Thousands ways to keep up with news or shop for anything online.
  • Pay bills, manage bank accounts, meet new people, watch TV, or learn new skills.
  • Earn money for those who doing business, selling million of stuff trough online.

Heyh you! We can learn or do almost anything online. Thanks Internet, we need you in our life!


The timeline of the Internet actually traces all the way back to the Vietnam War era: 1969. In that year, a team of defense engineers at the University of Los Angeles-California (UCLA) sent the first-ever instant message via computer to another team thousands of miles away at Stanford University.

From their work station in 3420 Boelter Hall, on the UCLA campus, the defense engineers had just set up the first node of Arpanet, a system funded by the Department of Defense’s Advance Research Projects Agency (ARPA). ARPA’s vision was for a system that would connect large computers at the Department of Defense’s various facilities so that they could share software, information, and storage space. UCLA would be one of its four main hubs—the University of Utah, SRI International, and UC-Santa Barbara would be the others.

In its short history the Internet has rapidly evolved from this simple, four-hub, military-only data grid to a planet-wide, universally accessed and accessible informational universe that we know and love today. But let’s face it: In history of information technology, a lot can happen in 44 years.
