The Internet is the vast web of cables connecting data centers all over the world. Its how we shop, post, and do everything online. However, many people don’t know how the Internet works. In today’s post, we’ll give you some background on what the Internet is and how it works.
What’s The Internet?
In order for computers to talk to one another, they must be connected to a network. The Internet is a large combination of all of these various computer networks. The full infrastructure of the Internet includes computers, data centers, routers, service repeaters, cables, satellites, and WiFi towers. All of these components allow you to shop, communicate, stream, and search online.
The Internet’s Size
The overall size of the Internet can be measured in a few ways. Firstly, connecting all these networks requires wiring, a lot of it. Cables cross all over countries totaling in the hundreds of thousands of miles. Additionally, an estimated 300 cables connect all of the continents on the seafloor. These consist are bundles of fiberoptic cables capable of transferring data at the speed of light. Secondly, an indication of the Internet’s size is the amount of data transmitted every day. On average, about five exabytes get processed every day. This is equivalent to about streaming 40,000 two hour SD movies per second, or a lot of data.
How Much Power Does It Use?
Huawei estimates that the information and communications technology industry will consume 20% of the world’s electricity. As a result, it will be responsible for more than 5% of carbon emissions.
How Many People Are Online?
The United Nations, more specifically the International Telecommunications Union, a part of the UN, counts online activity as using the Internet in the last three months. Using these criteria, approximately 48% of the world’s population was online by the end of 2018. However, this number isn’t reflective of an individual country’s usage. For example, about 95% of the residents of Britain and 89% of Americans are online. For America, this translates to about 300 million people.
