Internet? What is Internet? Process, Fundamental, Advantages, Disadvantages

There are billions of computers all over the globe connected to the Internet, which in turn links them to each other and to the World Wide Web. It connects billions of computer users all over the world by utilising the standard internet protocol suite (TCP/IP). There are several types of cables used, including optical fibres, in addition to other wireless and networking technologies. At the moment, the internet is the most efficient method of transmitting or sharing information and data between computers located all over the world.

It is thought that the “Defense Advanced Research Projects Agency” (DARPA) of the United States government was responsible for the development of the internet. In addition, the first connection was made in 1969.

What is the significance of the term “network” in relation to the Internet?

The Internet is referred to as a network because it builds a network by linking computers and servers all over the globe through the use of routers, switches, telephone lines, and other communication devices and channels, among other things. It may be regarded a global network of physical cables, including copper telephone wires, fibre optic cables, television cables, and other types of communications cable. Even wireless connections such as 3G, 4G, and Wi-Fi, which allow users to connect to the Internet without using a computer, rely on these wires to do so.

As opposed to the World Wide Web, which is a network of computers and servers connected through the internet, the internet is a network of computers and servers that are connected through the internet. As a result, the internet is considered to be the backbone of the web since it provides the technological infrastructure necessary for the establishment of the WWW and serves as a channel for the transmission of information from one computer to another. It displays the information on the client’s computer screen using web browsers, which it obtains from online servers.

The internet is not completely controlled by a single individual or group. It is a concept based on physical infrastructure that connects networks with other networks in order to create a global network of billions of computers. It is also referred to as the Internet of Things (IoT). As of August 12, 2016, there were more than 300 million internet users in the globe, according to the International Telecommunication Union.

What is the procedure for using the internet?

Please bear with us while we go over the following Internet terminology and concepts:

Clients and servers are necessary for the operation of the internet. Due to the fact that it is not directly linked to the internet, a device such as a laptop that is connected to the internet is referred to as a client rather than a server. This server is linked to the internet via an Internet Service Provider (ISP), and it can be recognised by its IP address, which is a string of digits, which is assigned by the ISP. An IP address serves the same purpose as a physical address in that it uniquely identifies your residence. An IP address also serves as the shipping address for your equipment. Your Internet service provider (ISP) provides the IP address, and you may view what IP address your ISP has assigned to your system.

A server is a powerful computer that is used to store webpages. It also has an Internet Protocol address. A data centre is a location where a large number of servers are housed in one location. The server receives requests from the client, which are sent by a browser through a network (the internet), and answers in the manner specified.

A domain name, which reflects an IP address number, is required in order to access the internet; each IP address has been allocated a domain name, as previously stated. IP addresses are represented by domain names such as,, and, among others. The creation of domain names was motivated by the fact that it is difficult to recall a long string of integers. Because the internet does not comprehend domain names, but only IP addresses, when you enter a domain name in the browser search box, the internet must first find all of the IP addresses for that domain name in a massive phone book, which is known as the Domain Name System (DNS) (Domain Name Server).

For example, if you know someone’s name, you may look for his phone number in a phone book by searching for his name in the phone book. The DNS server is used in the same way by the internet to determine the IP address associated with a domain name. DNS servers are controlled by Internet service providers (ISPs) or other similar organisations.

Let’s take a look at how the internet works now that we’ve covered the fundamentals.

The DNS server receives a request from your browser when you switch on your computer and input a domain name into the browser search box. Your browser then makes the request to the DNS server in order to obtain the appropriate IP address. Following the acquisition of the IP address, the browser passes the request to the appropriate server.

As soon as the server receives the request to offer information on a certain website, the information begins to flow. The data is conveyed across optical fibre cables in either digital format or in the form of light pulses, depending on the configuration. Due to the fact that the servers are located in remote locations, the data may have to travel hundreds of kilometres across an optical fibre connection before it can reach your computer.

Optical fibre is linked to a router, which turns the light impulses into electrical signals and then back again. An Ethernet cable is used to carry the electrical impulses from your computer to your laptop. Consequently, the information that you want is sent to you over the internet, which is basically a wire that links you to the server.

For more information, if you are using wireless internet, such as wifi or mobile data, the signals from the optical cable are first transported to a cell tower, from where they are transmitted to your cell phone in the form of electromagnetic waves.

It is controlled by the Internet Corporation for Assigned Names and Numbers (ICANN), which is headquartered in the United States. It is in charge of IP address assignment, domain name registration, and other such tasks.

When using the internet, data transfer is extremely quick. When you press the Enter key, you will get information from a server that is hundreds of kilometres away from your location. Due to the fact that the data is delivered in binary form (0, 1), and that these zeros and ones are broken into little bits called packets, which may be sent at fast speed, the data is transmitted at a rapid rate.

The following are some of the advantages of the Internet:

  • ● Instant Messaging: You may send messages or communicate with anybody using the internet, such as through email, phone chat, video conferencing, and other means of communication.
  • ● Obtain instructions: GPS technology allows you to obtain directions to practically any location in a city, nation, or other geographical area. You may discover restaurants, shopping malls, and any other service you require in your immediate vicinity.
  • ● Online Shopping: It enables you to shop online for a variety of items such as clothing, shoes, movie tickets, train tickets, aircraft tickets, and other items, among other things.
  • ● Paying Bills: You can pay your bills online, such as power bills, gas bills, college fees, and so on. You can even pay your taxes online.
  • ● Online Banking: It enables you to access your account information over the internet, where you may check your balance, receive or transfer money, obtain a statement, request a cheque book, and so on.
  • ● Selling Your Products or Services Online: You may make money by selling your products or services online. It assists you in reaching a greater number of clients, hence increasing your sales and profits.
  • ● Work from Home: If you need to work from home, you can do so by connecting to the internet using a computer or a laptop. Many organisations now enable their workers to work from the comfort of their own homes.
  • ● You may use the internet for entertainment by listening to music, watching films or movies, or playing online games.
  • ● Cloud computing: It is the ability to link your PCs and internet-enabled devices to cloud services such as cloud storage, cloud computing, and so on. Cloud computing is becoming increasingly popular.
  • ● Career development: You can look for jobs online on various job sites and send your CV to potential employers by email if that is what they demand.
