What is the Internet?

Short answer: a distributed packet-switched network. This is the introduction video to the series, "How the Internet Works". Vint Cerf, one of the "fathers of the internet" explains the history of how the net and how no one person or organization is really in charge of it. While it may seem like a simple question, defining the Internet isn’t easy. Because unlike any other technology, the Internet can be whatever we make it. We can shape it. We can mold it.

Who makes it work

The Internet ecosystem is made of many organizations and communities that help the Internet work and evolve. The rapid and continued development and adoption of Internet technologies can be attributed to the involvement of a broad range of people and organizations; open, transparent, and collaborative processes; and the use of products and infrastructure with dispersed ownership and control.

Terminology

When the term web is employed to see the particular international system of interconnected web Protocol (IP) networks, the word could be a proper name that ought to be written with AN initial upper case. In common use and therefore the media, it's typically mistakenly not capitalized, viz. the web. Some guides specify that the word ought to be capitalized once used as a noun, however not capitalized once used as AN adjective. the web is additionally typically said because the web, as a brief style of network. traditionally, as early as 1849, the word internetted was used uncapitalized as AN adjective, that means interconnected or interlacing. The designers of early laptop networks used web each as a noun and as a verb in shorthand style of internetwork or internetworking, that means interconnecting laptop networks.

Techopedia explains Internet

As computing advanced, peer-to-peer (P2P) communication was gradually delivered and enhanced. Since the 1990s, the internet has greatly influenced and upgraded networking to global standards. Billions of internet users rely on multiple application and networking technologies, including:

Internet Protocol (IP): The internet’s primary component and communications backbone. Because the internet is comprised of hardware and software layers, the IP communication standard is used to address schemes and identify unique busy connected devices. Prominent IP versions used for communications include Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6).

Communications: The internet is the most cost-effective communications method in a world that is now a global village, in which the following services are instantly available:
Email
Web-enabled audio/video conferencing services
Online movies and gaming
Data transfer/file-sharing, often through File Transfer Protocol (FTP)
Instant messaging
Internet forums
Social networking
Online shopping
Financial services
The internet originated with the U.S. government, which began building a computer network in the 1960s known as ARPANET. In 1985, the U.S. National Science Foundation (NSF) commissioned the development of a university network backbone busy called NSFNET. The system was replaced by new networks operated by commercial internet service providers in 1995. The internet was brought to the public on a larger scale at around this time.

Internet of Things (LOT)

The internet of things (IoT) may be a computing idea that describes the thought of everyday physical objects being connected to the net and having the ability to spot themselves to different devices. The term is closely known with RFID because the methodology of communication, though it conjointly might embrace different detector technologies, wireless technologies or QR codes. The IoT is important as a result of associate degree object that may represent itself digitally becomes one thing larger than the thing by itself. not will the thing relate simply to its user, busy however is currently connected to encompassing objects and info information. once several objects act in unison, they're referred to as having "ambient intelligence."

Where to Begin? Internet Addresses

Because the web could be a international network of pcs every computer connected to the web should have a singular address. web addresses area unit within the type nnn.nnn.nnn.nnn wherever nnn should be variety from zero - 255. This address is thought as associate information science address. (IP stands for web Protocol; additional on this later.)
The picture below illustrates 2 pcs connected to the Internet; your computer with information science address one.2.3.4 and another pc with information science address five.6.7.8. the web is painted as associate abstract object intermediate. (As this paper progresses, the web portion of Diagram one are explained and redrawn many times because the details of the web area unit exposed.) If you connect with the web through an online Service supplier (ISP), you're typically allotted a short lived information science address for the period of your dial-in session. If you connect with the web from an {area|a neighborhood} area network (LAN) your pc might need a permanent information science address or it'd acquire a short lived one from a DHCP (Dynamic Host Configuration Protocol) server. In any case, if you're connected to the web, your pc features a distinctive information science address.(busy.org)
