What is the Internet and its features?
Internet and its features: Internet is a system that connects various networks, computer systems around the world. In today’s world, Internet is a common term used all over the world and plays an important role in daily life. Nowadays, without the Internet, life is incomplete. The internet not only gives its users instant access to a huge pool of data and tools, but also helps in accessing information to perform various tasks. It is also used for business and other works.
What is the internet?
It is the larger network that allows computer networks around the world operated by businesses, governments, universities and other organizations to communicate with each other. Therefore, we can say that the Internet is a global system of interconnected computers, which uses a standardized Internet protocol for communication and information sharing.
The Internet carries a wide range of information resources and services, including the interconnected hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony and file sharing. The Internet system includes a wide range of information resources and services such as the WWW, technology, electronic mail, etc. Standard Internet protocols are used, including TCP/IP and HTTP, etc.

Internet: origin and development
Early computer networks, including SABER (an airline reservation system) and AUTODIN I (a defense command and control system) were dedicated special-purpose systems, designed and implemented in the late 1900s. 1950s and early 1960s.
Computer manufacturers had begun in the early 1960s to use semiconductor technology in commercial products. And also with the conventional batch processing and time-sharing systems that have been placed in various large technologically advanced enterprises. The time-sharing feature made it possible to quickly share a computer’s resources with multiple users, quickly browsing through a queue of users, and the computer seemed dedicated to each user’s tasks despite the existence of various accesses to the system “simultaneously”. This led to the concept of sharing computing resources across an entire network.
On October 29, 1969, the first host-to-host network connection was established. It was developed by the Advanced Research Projects Agency (ARPA) of the US Department of Defense. One of the first general purpose computer networks was an ARPANET.
In addition, tools and applications have emerged, including Simple Mail Transfer Protocol (SMTP) and File Transfer Protocol (FTP).
A new technology has also been employed by ARPANET, namely packet switching. It takes large messages and breaks them into smaller, manageable messages.
In the 1970s, commercial packet networks were introduced and were designed to provide efficient access to remote computers through dedicated terminals.
Long distance modem connections have been replaced by cheaper “virtual” circuits over packet networks.
Initiatives for terrestrial and satellite packet networks have been supported by DARPA (Defense Advanced Research Projects Agency) formerly known as ARPA. Due to the introduction of packet radio, connecting a mobile terminal to a computer network has become easy or feasible.
The main characteristics of the Internet are listed below:
Easy to use
The software used to access the Internet or web browser is designed very simply and can be easily learned and used. Moreover, it is easy to develop.
Flexibility in terms of data transfer. Basically, the Internet network carries information in digital form in the majority of cases instead of voice information in analog form.
The Internet service is a worldwide service and access to all. People at a distance or anywhere indoors can also use the internet. Therefore, information via the Internet flows over networks in a standardized way.
Interaction with the media and flexibility of communication
Businesses are growing with the help of internet. There is a high degree of media interaction due to the internet service. Like, News, Magazines, Publishing Houses, etc. have expanded their business with the help of the internet service. In addition, communication is flexible thanks to the Internet service. With the help of text voice, video people can communicate easily.
Low cost and safety
Internet service maintenance and development costs are relatively low. In addition, the Internet service has helped the security system both at individual and national level. For example, CCTV cameras, etc.
It is part of the Internet and supports hypertext documents, allowing users to view and navigate through different types of data. A web page is a document coded with HTML (Hypertext Markup Language) tags. Each web page has an address, URL (Uniform Resource Locator).
Electronic mail (email)
One of the most popular reasons people use the Internet is through email. And to create, send and receive e-mail messages, users need an e-mail program and an account on an Internet mail server with a domain name.
File Transfer Protocol (FTP)
It is the internet tool which is used to copy files from one computer to another. Using this, a person can connect to an ETP host computer via the Internet and copy files to their computer. It is convenient for finding and copying software files, articles and other types of data.
It is a specialized service with which a person can use one computer to access the content of another computer, a telnet host. It is widely used by libraries to allow visitors to search for information, find articles, etc.
Internet Relay Chat (IRC) (real-time video chat)
This service allows users to communicate in real time by typing text in a special window.
