What is Internet ?
* "The Internet, sometimes called simply" the Net," is a world wide system of computer network. A network of networks in which user at any one computer can if they have permission, get information from any other computer (and sometimes talk directly to users at other [computers.)"
It was conceived by the Advanced Research Projects Agency [A.R.P.A] of the US government in 1969 and was first known as the ARPANET.
The original aim was to create a network that would allow users of a research computer at one university to "talk" to research computer at Other universities.
How Does the Internet works ?
The actual working of the internet takes place with the help of clients and servers. Here the client is a laptop that is directly connected to the Internet and server are the computers connected Indirectly to the Internet and they are having all the websites stored in those large computers. These one connected to the Internet with the help of ISP (Internet Service Providers) and will be identified. with the IP address. Each website has its Domain name as it is difficult for any person to always remember the long you search numbers or strings. So, whenever domain name in the search bar of the Browers the request will be sent to the server and that server corill try to find the IP address from the Domain name because it cannot understand the domain name.
After getting the IP address the server will try to search of the Demain name in a huge phone directory. that in networking is known as a DNS server ( Domain Name Server).
for example-
If we have the name of a person and you can easily find the adhar number of him/her from the long directory as simply Or that so after getting the IP address the browser will pass on the further request to the respective server and now servers will process the request to display ! the the content of the website which the client wants. If you are using a wireless medium of Internet like 3g and 4g or other mobile data then the data will stant from the optical cables and will first reach to toward from there the signals will reach your cell phones and "Pc's through electromagnetic waves. And if you are using routers then optical fiber connecting to your router will help in connecting to your those light-induced signals into. electrical signals and with the help of ethernet cables Internet reaches Information. your computer and hence the required information.
