What is the internet? The Internet is a massive network that links computers all around the world. People may exchange information and converse through the Internet from any location with an Internet connection. The Internet provides an extensive array of information resources and services, such as the World Wide Web’s (WWW) inter-linked hypertext pages
Internet
The Internet is a global network of interconnected computer networks that communicate over the Internet protocol suite (TCP/IP). It is a network of private, public, academic, corporate, and government networks ranging from local to global in extent and connected by a diverse set of electrical, wireless, and optical networking technologies.
Capitalization of “Internet”
The term “internet” was first used in 1849 to denote “interconnected or interwoven.” In 1974, the term “Internet” was coined as a shorthand for “Internetwork.” The term “Internet” now most usually refers to the worldwide system of interconnected computer networks. However, it can also apply to any set of smaller networks.
When it first became popular, most newspapers capitalized the word Internet as a proper noun; now, this has become less prevalent.
It mirrors the English trend to uppercase new terms and then lowercase them as they become more familiar.
The Internet’s History
-
In the 1960s, the United States Department of Defense’s Advanced Research Projects Agency (ARPA) financed research into computer time-sharing. Research on packet switching, one of the essential Internet technologies, began in the early 1960s with Paul Baran and, separately, Donald Davies in 1965.
-
Following the Symposium on Operating Systems Principles in 1967, packet switching from the planned NPL network was included in the ARPANET architecture and other resource-sharing networks built in the late 1960s and early 1970s, such as the Merit Network and CYCLADES.
-
ARPANET development began on October 29, 1969, with the interconnection of two network
nodes between the Network Measurement Center at the University of California, Los Angeles (UCLA) Henry Samueli School of Engineering and Applied Science directed by Leonard Kleinrock and the NLS system at SRI International (SRI) directed by Douglas Engelbart in Menlo Park, California. -
The Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, was the third location, followed by the University of Utah Graphics Department. By the end of 1971, 15 locations were linked to the fledgling ARPANET, indicating potential expansion. Computer Networks, a 1972 film, chronicled these early years.
Internet administration
The Internet is a worldwide network made up of numerous independent networks that are interconnected willingly. It does not have a central governing body. The Internet Engineering Task Force (IETF) is responsible for the technical basis and standardization of the fundamental protocols (IPv4 and IPv6). The IETF is a non-profit organization of loosely associated multinational members that anybody can join by giving technical skills.
The Internet Corporation for Assigned Names and Numbers (ICANN) manages the Internet’s primary namespaces to ensure compatibility (ICANN). ICANN is administered by a multinational board of directors comprised of individuals from all around the world.
Infrastructure
The Internet’s communications infrastructure comprises hardware components and a series of software layers that regulate various parts of the architecture. Like any other computer network, the Internet is made up of routers, media (such as cables and radio connections), repeaters, modems, and so on.
However, as an example of internetworking, many network nodes are not necessarily internet equipment per se; other full-fledged networking protocols carry internet packets. The Internet acts as a homogeneous networking standard, running across heterogeneous hardware, with IP routers guiding the packets to their destinations.
A suite of Internet Protocols
-
The Internet standards define a framework known as the Internet protocol suite (TCP/IP because of the first two components). It is a set of protocols organized into four conceptual levels based on the scope of their operation, as specified in RFC 1122 and RFC 1123.
-
The application layer is at the top, where communication is characterized by the objects or data structures most suited for each application.
-
A web browser, for example, operates in a client-server application architecture and exchanges data with the Hypertext Transfer Protocol (HTTP) and an application-specific data structure, such as the Hypertext Markup Language (HTML).
-
Services and applications
Most notably, the World Wide Web, the Internet supports a wide range of applications and services, including social media, electronic mail, mobile apps, multiplayer online games, Internet telephony, file sharing, and streaming media services.
Most of these computers are now located in data centers, and material is frequently accessible via high-performance content delivery networks.
World Wide Web
The World Wide Web is a global collection of papers, pictures, videos, applications, and other resources linked together logically by hyperlinks and identified by Uniform Resource Identifiers (URIs), which create a global system of named references.
URIs represent the symbolic identification of services, web servers, databases, and the documents and resources they can supply. The World Wide Web’s primary access protocol is the Hypertext Transfer Protocol. HTTP is also used by web services to communicate with software systems for information transmission, sharing, and exchanging corporate data and logistics and is one of several languages or protocols that may be used for communication on the Internet.
Users can move from one online page to another via hyperlinks included in the documents using World Wide Web browser software such as Microsoft’s Internet Explorer/Edge, Mozilla Firefox, Opera, Apple’s Safari, and Google Chrome.
These documents may also include any mix of computer data, including pictures, audio, text, video, multimedia, and interactive content, which runs as the user interacts with the page. Animations, games, office applications, and scientific presentations are examples of client-side software.
Communication
Email is a vital communication service that is accessible over the Internet. Sending electronic text messages between parties, similar to mailing letters or notes, predates the development of the Internet. Email attachments are used to send pictures, documents, and other things. Email messages can be copied to many recipients.
Data transmission
Transferring massive volumes of data through the Internet is an example of file sharing. As an attachment, a computer file can be sent to clients, coworkers, and friends. It may be uploaded to a website or a File Transfer Protocol (FTP) server for others to download easily. It can be saved in a “shared location” or on a file server for immediate access by colleagues. Using “mirror” servers or peer-to-peer networks can alleviate the stress of mass downloads to multiple consumers.
The social impact
The Internet has opened up new avenues for social contact, activities, and social connections. This phenomenon has given rise to the scientific field of Internet sociology.
Users
From 2000 to 2009, the worldwide Internet user population increased from 394 million to 1.858 billion. By 2010, 22% of the world’s population had access to computers, with 1 billion Google searches per day, 300 million Internet users reading blogs, and 2 billion YouTube videos viewed daily.
In 2014, the global Internet user population topped 3 billion, accounting for 43.6 percent of the global population; nevertheless, two-thirds of the users were from the wealthiest nations, with 78.0 percent of Europe’s population using the Internet, followed by 57.4 percent of the Americas.
However, by 2018, Asia alone accounted for 51% of all Internet users, with 2.2 billion of the world’s 4.3 billion Internet users hailing from the area. China’s Internet user base achieved a significant milestone in 2018, when the country’s Internet regulatory authority, the China Internet Network Information Centre, stated that the country had 802 million Internet users.
Worldwide Internet users
| Users | 2005 | 2010 | 2017 | 2019 |
|---|---|---|---|---|
| World population | 6.51 billion | 6.92 billion | 7.43 billion | 7.74 billion |
| Worldwide | 16.2% | 30.2% | 48.3% | 53.64% |
| In developing world | 8.1% | 21.6% | 41.3% | 47.1% |
| In developed world | 51.3% | 67.1% | 81.8% | 86.7% |
By 2019, China had more than 800 million Internet users, followed closely by India, which had 700 million users, while the United States, which had 275 million users, was a distant third. However, in terms of ■■■■■■■■■■■, China has a 38.4 percent ■■■■■■■■■■■ rate, compared to India’s 40% and the US’s 80%. It is anticipated that 4.5 billion people, or more than half of the world’s population, will be using the Internet by 2020.
Usage
With the proliferation of unmetered high-speed Internet connections, the Internet offers greater flexibility in working hours and location. The Internet may be accessed practically anywhere using a variety of methods, including mobile Internet devices. Users can connect to the Internet wirelessly using mobile phones, data cards, portable gaming consoles, and cellular routers.
The Internet services, including email and the web, may be provided within the constraints imposed by small displays and other restricted capacities of such pocket-sized devices. Service providers may limit their services, and mobile data prices may be much more than traditional ways of access.
Websites provide educational materials ranging from pre-school to post-doctoral degrees. Examples vary from CBeebies to school and high-school revision manuals and virtual universities, as well as access to top-tier scholarly literature via services such as Google Scholar.
Entertainment and social networking
Many individuals use the Internet to get news, weather, and sports updates, plan and book vacations, and follow personal hobbies. People use chat, texting, and email to make and keep in touch with people worldwide, sometimes in the same manner that they used to have pen pals. Social networking sites like Facebook have given rise to new methods to mingle and connect.
Users may add a wide range of material to pages, explore shared interests, and communicate with others on these sites. It is also feasible to locate pre-existing acquaintances and facilitate contact among pre-existing groups of individuals. LinkedIn and other such sites facilitate commercial and business interactions.
Users’ videos and images are the focus of YouTube and Flickr. Businesses and other organizations also utilize social networking platforms to promote their brands, sell to their consumers, and encourage posts to “go viral.” Some groups also use “black hat” social media practices, such as spam accounts and astroturfing.
Electronic commerce
Electronic business (e-business) refers to all company procedures covering the entire value chain, including purchasing, supply chain management, marketing, sales, customer support, and business relationships. E-commerce strives to increase income streams by utilizing the Internet to develop and strengthen connections with customers and partners.
According to International Data Corporation, the total value of global e-commerce in 2013 was $16 trillion when business-to-business and consumer-to-business transactions were included. According to an Oxford Economics analysis, the overall value of the digital economy is estimated to be $20.4 trillion, or around 13.8 percent of worldwide sales.
Telecommuting
Telecommuting is the work performed within a traditional worker-employer relationship that is made possible by tools such as groupware, virtual private networks, conference calling, videoconferencing, and VoIP, allowing work to be performed from any location, most conveniently the worker’s home.
It may be effective and beneficial for businesses since it lets employees interact across great distances while saving considerable travel time and money. As broadband Internet access becomes more ubiquitous, more workers will have enough capacity at home to use these technologies to connect to their workplace intranet and internal communication networks.
Publishing in collaboration
Wikis have also been utilized in academia for knowledge exchange and dissemination across institutional and international borders. They are beneficial in those situations for grant writing, strategy planning, departmental paperwork, and committee work. The US Patent and
Trademark Office uses a wiki to allow the public to locate prior art relevant to the assessment of pending patent applications. A wiki was utilized in Queens, New York, to allow locals to engage in the design and development of a local park.
Politics and political upheavals
As a political instrument, the Internet has gained new traction. Howard Dean’s presidential campaign in the United States in 2004 was renowned for its effectiveness in seeking donations over the Internet.
Many political parties utilize the Internet to attain a new means of organizing for carrying out their objective, giving rise to Internet activism, which Arab Spring revolutionaries most prominently did.
According to the New York Times, social media networks such as Facebook and Twitter aided activists in organizing rallies, communicating concerns, and disseminating information during Egypt’s political upheavals.
Security
Criminal or malevolent attempts to obtain unauthorized control of Internet resources, hardware, and software components to cause disruptions, commit fraud, participate in blackmail, or access private information are shared.
Summary
When using a web browser to view web pages, the phrases Internet and World Wide Web are frequently used interchangeably; it is usual to talk of “going on the Internet.” However, the World Wide Web, sometimes known as the Web, is just one of many Internet services.
Frequently Asked Questions
People ask many questions about the Internet. a few of them are discussed below:
1. What is the purpose of the Internet?
The Internet allows you to locate information fast, contact people all over the globe, manage your finances, buy from home, listen to music, view movies, and do so much more. Let’s take a look at some of the most frequent ways people utilize the Internet nowadays.
2. Who made the Internet?
Bill Gates did not invent the computer and the Internet. Charles Babbage, an Englishman, created the computer. He constructed the world’s first mechanical computer and conceived the notion of a programmable computer.
3. Is it true that Steve Jobs invented the Internet?
So, according to the myth, Berners-Lee conceived the WWW, and Steve Jobs had no involvement with the notion other than Berners-Lee owning one of the few NeXT machines. Indeed, Jobs had less to do with the WWW than Al Gore did with the Internet.
4. Does anyone own the Internet?
Some organizations decide the structure and operation of the Internet, but they do not own the Internet itself. No government, nor any entity, can claim ownership of the Internet. The Internet is like the telephone system in that no one owns the whole network.
5. Is it possible to turn off the Internet?
Disabling the entire Internet would be like attempting to halt the flow of all rivers on the planet simultaneously. No, there isn’t a single connecting point through which all data travels, and the internet protocol was mainly created so that data finds a way around downed portions of the network.
Conclusion
The internet is a larger network that allows computer networks controlled by enterprises, governments, colleges, and other organizations all over the world to communicate with one another. As a result, there is a tangle of cables, computers, data centres, routers, servers, repeaters, satellites, and wifi towers that allow digital data to go across the world.
