The internet is the global hub of computer networks around the world. It is a vast network of connections through which authorized users can communicate and exchange data with other systems.
Through the internet, we can exchange pictures, messages, and videos with our loved ones. If an internet connection is provided to a computer or mobile device, it can access numerous services, including social media, websites, and more. The internet is the largest means of sharing information nowadays.
How the Internet works ?
The process of transferring data over the internet from one device to another depends on packet switching. The internet is a packet-routing network that uses IP (Internet Protocol) and TCP (Transmission Control Protocol) for communication. When a person visits a website, their computer or mobile device sends a request to the server using these protocols.
Below are some examples of how this process works :
1. Connecting Computers : The fundamental foundation of the internet is an interconnected network of computers. When two computers connect, they must be physically (typically through an Ethernet connection) or wirelessly connected (via Wi-Fi or Bluetooth). All modern systems can support any of these connections to establish a core network.
2. Email : Brief for electronic mail, email is a way to send and receive messages over the internet. Nearly everybody who uses the internet has their own email account, usually called an email address. This is because you’ll need an email address to do almost anything online, from online banking to creating a Facebook account.
3. Education : The internet plays an important role in education. Much important information about education is stored on servers and provided as educational material. Apart from this, physically challenged people can choose various courses from the internet and acquire education at home. In the modern world, various high-class educational institutions around the world are providing online education on digital platforms and delivering quality education through the internet.
4. Social Network : Social networks are the most powerful networks in the world today. The purpose of social networks is to unite people from all over the world. With the help of social networks, we can share videos and pictures instantly with our friends or relatives from anywhere in the world. Also, through social networks, we can create groups for official discussions or meetings.
5. Entertainment : The internet is very important for entertainment. There are many entertainment options on the internet like playing games, listening to music, and watching videos. Besides, movies, songs, TV serials, etc., from any country in the world can be easily accessed with the help of the internet and can be downloaded as needed.
6. Chat and Instant messaging : Chat and instant messaging (IM) are short messages sent in real-time, offering the speed necessary for quick conversations. When both people are connected to the internet, they can send messages instantly. However, in the case of emails, the emails cannot be seen until the inbox is checked.
7. Connected the internet to the web : The internet is an important network capable of connecting billions of machines to each other. Several of these machines can connect to a server and serve different browsers. The web is an important application built on the internet.
8. Cashless Transactions : Today, all the big companies in the world are providing services to pay for their products through various digital payments. In this case, they are accepting payments through various digital payment apps like Google Pay, Paytm, etc. Additionally, various apps are being used to transfer money from one country to another. All of this is possible thanks to the internet.
9. Searching for jobs : Nowadays, the internet is playing an important role in employment. Employers advertise various jobs on the internet according to their needs, and job seekers submit applications through these platforms according to their qualifications. For example, on social networking sites such as LinkedIn, both employers and applicants use the internet to recruit and identify candidates.
