World Wide Web

WebWWWthe web
The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
The World Wide Web (WWW), commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs, such as ), which may be interlinked by hypertext, and are accessible over the Internet.

ARPANET

ARPA networkDarpanetAdvanced Research Projects Agency Network
The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Research into packet switching, one of the fundamental Internet technologies, started in the early 1960s in the work of Paul Baran, and packet-switched networks such as the NPL network by Donald Davies, ARPANET, the Merit Network, CYCLADES, and Telenet were developed in the late 1960s and early 1970s.
Both technologies became the technical foundation of the Internet.

Computer

The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network.
The Internet is run on computers and it connects hundreds of millions of other computers and their users.

Newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators.
Websites can be accessed via a public Internet Protocol (IP) network, such as the Internet, or a private local area network (LAN), by a uniform resource locator (URL) that identifies the site.

The Internet (portmanteau of interconnected network) is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.
The best-known computer network is the Internet.

Online shopping

online retaileronline storeonline shop
Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online.
Online shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser.

Domain Name System

DNSresource recordDNS record
The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN).
The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.

Brick and mortar

brick-and-mortarbricks and mortarbrick and mortar business
Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online.
This term is usually used to contrast with a transitory business or an Internet-only presence, such as fully online shops, which have no physical presence for shoppers to visit, talk with staff in person, touch and handle products and buy from the firm in person.

Web page

The terms Internet and World Wide Web are often used interchangeably in everyday speech; it is common to speak of "going on the Internet" when using a web browser to view web pages.
This is a type of software that can retrieve web pages from the Internet.

Internet Protocol

IPIP protocolInternet Protocol (IP)
When the term Internet is used to refer to the specific global system of interconnected Internet Protocol (IP) networks, the word is a proper noun according to the Chicago Manual of Style that should be written with an initial capital letter.
Its routing function enables internetworking, and essentially establishes the Internet.

Telenet

Research into packet switching, one of the fundamental Internet technologies, started in the early 1960s in the work of Paul Baran, and packet-switched networks such as the NPL network by Donald Davies, ARPANET, the Merit Network, CYCLADES, and Telenet were developed in the late 1960s and early 1970s.
Sprint migrated customers from Telenet to the modern-day Sprintlink IP network, one of many networks composing today's Internet.

CSNET

Computer Science Network
Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) funded the Computer Science Network (CSNET).
It played a significant role in spreading awareness of, and access to, national networking and was a major milestone on the path to development of the global Internet.

ARPANET development began with two network nodes which were interconnected 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) by Douglas Engelbart in Menlo Park, California, on 29 October 1969.
The school is credited as the birthplace of the Internet, where the first message was sent to a computer at Stanford University on October 29, 1969 by Professor Leonard Kleinrock and his research team at UCLA.

As technology advanced and commercial opportunities fueled reciprocal growth, the volume of Internet traffic started experiencing similar characteristics as that of the scaling of MOS transistors, exemplified by Moore's law, doubling every 18 months.
Internet traffic is the flow of data within the entire Internet, or in certain network links of its constituent networks.
