World Wide Web and The Internet

Some children may play on-line games, chatting or emailing each other under the pretext of doing Homework. A handy program named “Ping” is used to ensure internet connection. Here, “No,” any computer knows the location of any other computer connected to the internet.

  • You should now be able to join that Windows 8 network on your other device.
  • If one point was destroyed, all surviving points would still be able to communicate with each other.
  • ; on-line area, like an electronic bulletin board, where users can read and add or “post” comments about a specific topic.
  • Aside from using an app or third-party program to enable wireless hotspot routing, these are the only ways to get the job done.
  • It also finds out what you want to do, and passes on the information in a way that the internet can understand.
  • Here, “No,” any computer knows the location of any other computer connected to the internet.

Vint Cerf is credited with the first written use of the word ‘internet’. An engineer whose work overlapped with ARPA’s research. In 1959 he joined an American think tank, the RAND Corporation, and was asked to research how the US Air Force could keep control of its fleet if a nuclear attack ever happened. In 1964 Baran proposed a communication network with no central command point.

What is the Internet and how does it work? How do computers and smartphones communicate with one another?

There exists an enormous routing table at the backbone of the NSP. The packet will be dispatched to the real backbone at this stage, and it will start moving downward via smaller networks until it reaches the destination. Many of these are available 24/7 from any device with an internet connection but there are some services that are only available on library computers because of licensing restrictions. Wi-Fi is a way of transmitting computer data through the air using radio waves.

What broadband is

The Windows 10 Anniversary Update added the ability to share your network connection while maintaining the one on the laptop or desktop. To set up a Mac or Windows laptop as a wireless router, you can use an app that does it all for you or set it up manually within the operating system. Using your Mac as a hotspot tends to cut Wi-Fi off because it needs to use the component as the Wireless Local Area Connection . However, Windows 10/11 offers a Wi-Fi Direct Virtual Adapter that allows the Wi-Fi to continue working on the desktop or laptop. This setting is an excellent feature that many people use, some more than others. There are also Wi-Fi hotspots which can give you access to fixed-line broadband at different locations.

Between 1986 and 1987, the network grew from 2,000 hosts to 30,000. People were now using the internet to send messages to each other, read news and swap files. After the creation of ARPANET, more networks of computers began to join the network, and the need arose for an agreed set of rules for handling data. In 1974 two American computer scientists, Bob Kahn and Vint Cerf, proposed a new method that involved sending data packets in a digital envelope or ‘datagram’. The address on the datagram can be read by any computer, but only the final host machine can open the envelope and read the message inside.
