The Internet

There is now more than 3.2 billion people using the internet.

How was the internet created?

The internet was not invented by a single person, but instead many engineers and programmers worked it. Late 1960s was when the first useful prototype was mocked up, it was called the Advanced Research Projects Agency Network (ARPANET) . It operates by packet switching, which is the method of breaking down data into chunks, making it efficient to move data around a network. Years later internet standards like TCP and IP were included. The introduction of the World Wide Web (WWW) molded the internet to more of what it is now as it made data sharing easier and offered a superior connection of networks around the world.

How the internet works?

Simply put the internet is a wire. All devices that are connected to this wire can communicate with each other. Servers are key to the workings of the internet, they are devices which are designed to process requests and deliver data to other computer which are connected to the internet. Web pages are files on servers hard drive, each server has an IP address, which is a unique so it helps other servers find each other. They also have URL’s which help humans identify them, for example: www.currentcomputingnews.wordpress.com. Computers that everyday people use are called Clients because they are not directly connected to the internet, so for clients to access a web page they have to pass an internet service provider in order to connect to a web page. Routers are also an integral part of the internet as they forward packets from the Internet service provider to servers.

Problems of the Internet

  • Security – There are many vulnerabilities on the internet as it was not created to handle cyber criminals. Hackers will exploit these vulnerabilities for a long time to come. As the internet becomes more significant to our lives , hackers will have a larger effect on out lives and our security.
  • Censorship – Information can be witheld from us to protect large companies, so people are not able to tell if information is true or not.
