New Digital Hub
What is Internet-The most crucial tool and well-known resource used by practically everyone on earth is the Internet. It links millions of computers, webpages, websites, and servers. We may communicate with our loved ones online by sending emails, pictures, videos, and messages. Or put another way, the Internet is a vast network of electronics and computers connected (that support the Internet). It produces a communication channel for online information sharing and retrieval. Only you will have access to all the applications, websites, social networking apps, and other services if your smartphone link to the Internet. The fastest method for sending and receiving information nowadays believe to be the Internet.
Origin of the Internet: The first functional version of the Internet, ARPANET, was developed in 1960. (Advanced Research Projects Agency). It was their most significant breakthrough at the time since it made it possible for several computers to operate on a single network. ARPANET uses packet switching to communicate across several computer systems on a single web. The first message was sent from one computer to another using ARPANET in October 1969. After then, technology keeps developing.
How is the Internet set up?
Physical copper or optical fibre data transmission cables and other networking infrastructure types, including LAN, WAN, and MAN, are used to set up the Internet. Even 2G, 3G, and 4G services and WiFi require this physical cable configuration to access the Internet. The management of the Internet and its associated protocols, such as IP addresses, is carried out by a body called ICANN (Internet Corporation for Assign Names and Numbers), which is improper in the USA.
How does the internet work?
Clients and servers are necessary for the actual operation of the Internet. In this case, the servers are the enormous computers indirectly connected to the Internet and house all the websites. At the same time, the clients are laptops directly related to the Internet. These servers identify by their IP addresses and connected to the Internet via ISPs (Internet Service Providers). As it is always challenging to recall long numbers or strings, each website has its domain name. As a result, anytime you enter a domain name in the browser’s search box, a request to the server, which then attempts to deduce the IP address from the domain name because it does not understand domain names. After obtaining the IP address, the server will try to locate the IP address of the domain name in a massive phone book or DNS server, as known in networking (Domain Name Server). For instance, if we see a person’s name, we may quickly get their Aadhaar number from a lengthy directory.
Therefore, the browser will forward the subsequent request to the appropriate server after obtaining the IP address. The server will then process the request to display the requested website content. If you use a wireless Internet connection, such as 3G and 4G or other mobile data, the data will begin to flow from optical cables and will first reach towers; from there, the signals will travel to your cell phones and PCs via electromagnetic waves. And if you use routers, then connecting optical fibre to your router will assist in converting those light-induced signals into electrical signals. With ethernet connections, internet access is possible on your PCs, providing the necessary data.
What is an IP address?
Internet protocol address is what is known as an IP address. Every PC or local device has an IP address given to it by Internet service providers (ISPs). When a device links to the net, some sets of guidelines control how data is a transmission. It distinguishes between computers, websites, and routers. Similar to human identification cards like Aadhaar, Pan, or any other unique identifying documents. For identifying purposes, each laptop and desktop has its IP address. It’s a crucial component of internet technology. Four digits, such as 192.154.3.29, represent an IP address. Here, each number in the set is between 0 and 255. Consequently, the entire IP address ranges from 0.0.0.0 through 255.
By selecting Network from the Windows start menu, right-clicking, then selecting Status and then Properties, you can view your laptop’s or desktop’s IP address. There are four different kinds of IP addresses available:
- Static IP address
- dynamic IP address
- Public IP address
- Private IP address
World Wide Web(WWW)
The world wide web [WWW] is a collection of all web pages and publications that can be found online by searching for their URLs (Uniform Resource Locator). For instance, the GFG website’s URL is www.geeksforgeeks.org, and its entire content, including all its sites and web documents, is kept online. Or, to put it another way, the web’s information retrieval service. It offers users access to a vast collection of documents that link to one another using hypertext or hypermedia links. Hypertext allows users to pick a word or phrase from a text and use that word or phrase to access other documents that contain additional information relates to that word or phrase. Hyperlinks are electronic connections that link the related data so that users can easily access the related information. For scientists at CERN to collaborate successfully, Timothy Berners-Lee developed the world’s vast web project in 1989. World Wide Web Consortium (W3C) is a company that promotes web innovation.
Difference between Worldwide Web and the Internet
The following are the ways that the net and the world wide web differ:
The World Wide Web is where all the web pages and documents usual, and each website has a unique URL that can use to access its contents. In contrast, the Internet is a vast computer network that can access through the World Wide Web.
- The Internet is an infrastructure, but the world wide web is a service.
- The Internet is a superset of the Internet, whereas the world wide web is a subset of the Internet.
- The Internet is hardware-oriented, whereas the world wide web is software-oriented.
- IP addresses are used on the Internet, while HTTP uses on the world wide web.
- The Internet is comparable to a library, and all many types of content, including books on various topics, can be compared to the Internet.
