Making a requestIn the first instance, when you open an internet file or visit webpage, a request is transmitted to the web server. Text files and image files are delivered faster than video files since videos are heavy files.So what is the mechanism through which information circulates on the internet?Let’s envisage that you are browsing through a webpage which contains images. How is the image transmitted to your computer?Sending a requestA web server is actually responsible for hosting the image. A request is transmitted from your computer to the webserver to access the imageThis request is usually transmitted in a “packet”, which by definition is a computer-generated or cybernetic parcel which contains lots of vital information. The web servers IP address which stores the image and your computer’s IP address are the most vital pieces of information on the packet.There are some special computer devices known as switches and routers, these devices redirect the packet data or cybernetic parcel from your system back to the server, which can be in a close range or in other parts of the globeAround the worldThe cybernetic parcel or packet data can be transmitted to every country in the world by making use of satellites or passed them through the sea using fiber optic cablesReceiving informationImmediately after you have received all the packet data, the file will be shown on your screen. Since the packet data has now been received, it will be opened by the packet data and the request of the computer will be interpreted, which in this instance is “ forward this message to me.”Image files are usually fairly large, hence there is need for them to be fragmented into bits of packets, usually up to hundreds and thousands pf bits. All the packet data contain information on the manner they will be assembled again as well as their destination and originDifferent routesThese packet data are sent back to your computer by the web server with the help of switches and routers. The router usually tries locates the quickest route for individual packet data, this might necessitate them taking diverse routes and may not be received in the same arrangement with which they were dispatched.Assembling the packet dataSince the whole packet data have now been retrieved, the information embedded in them instructs your computer how to assemble them and once that is done, your screen will display the image. All this long process is executed under a second!Data packetsAt the time of dispatching information to different computers, it is usually fragmented into tiny bits of data known as ‘packets’. An individual packet contains information about the origin and destination of the data as well as ways of assembling itIP addressIP address otherwise known as Internet Protocol address is the address used by computers to identify and locate one another. It functions like a postal address that is exclusive to individual computers linked to the net. An internet protocol address is a series of digits which are in this form: 192.333.44.14.SwitchA switch is a smart device or object that connects or linkes various devices together to enable them function as a network. At times, simpler devices known as ‘hubs’ are utilized.RouterRouter is a smart device which routes or directs information all over the internet. Once a packet data is received, the information of the IP address will be read by the router and consequently dispatch the packet along the fastest route to its targeted recipient.
