The Internet is a global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
An Internet Protocol address is a numerical label such as 192.0.2.1 that is connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: network interface identification and location addressing.
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
The liberalization of Bangladesh's telecommunications sector began with small steps in 1989 with the issuance of a license to a private operator for the provision of inter alia cellular mobile services to compete with Bangladesh Telegraph and Telephone Board (BTTB), the previous monopoly provider of telecommunications services within Bangladesh. Significant changes in the number of fixed and mobile services deployed in Bangladesh occurred in the late 1990s and the number of services in operation has subsequently grown exponentially in the past five years.
Multihoming is the practice of connecting a host or a computer network to more than one network. This can be done in order to increase reliability or performance.
Internet Protocol television (IPTV) is the delivery of television content over Internet Protocol (IP) networks. This is in contrast to delivery through traditional terrestrial, satellite, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the source media continuously. As a result, a client media player can begin playing the content almost immediately. This is known as streaming media.
Tessellis S.p.A. is an Italian telecommunications company founded in 1998 and based in Cagliari, Sardinia, that provides Internet and telecommunications services in Italy, and, previously had operations in other European nations through its acquisition of many smaller European Internet Service Providers (ISPs) in the late 1990s.
Plusnet plc is a British triple play internet service provider (ISP); providing broadband, landline and mobile services. The company was founded in 1997 in Sheffield, England, and became a public limited company (plc) in July 2004 when it was floated on the Alternative Investment Market. On 30 January 2007, Plusnet was acquired by BT Group, but it continues to operate as a separate business. By December 2013, it had over 750,000 customers across the UK.
In the context of computer networking, a tunnel broker is a service which provides a network tunnel. These tunnels can provide encapsulated connectivity over existing infrastructure to another infrastructure.
Free is a French telecommunications company, subsidiary of Iliad that provides voice, video, data, and Internet telecommunications to consumers in France. Its head office is in the 8th arrondissement of Paris and it is the second-largest ISP in France.
IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses. Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s, when the Internet started experiencing dramatic growth. This depletion is one of the reasons for the development and deployment of its successor protocol, IPv6. IPv4 and IPv6 coexist on the Internet.
An IPv6 transition mechanism is a technology that facilitates the transitioning of the Internet from the Internet Protocol version 4 (IPv4) infrastructure in use since 1983 to the successor addressing and routing system of Internet Protocol Version 6 (IPv6). As IPv4 and IPv6 networks are not directly interoperable, transition technologies are designed to permit hosts on either network type to communicate with any other host.
The United Kingdom has been involved with the Internet throughout its origins and development. The telecommunications infrastructure in the United Kingdom provides Internet access to businesses and home users in various forms, including fibre, cable, DSL, wireless and mobile.
SSi Canada is a Canadian wireless broadband internet service provider primarily serving remote areas that lack terrestrial service options. SSi was established in 1990 by Jeffrey Philipp and is headquartered in Yellowknife, capital of the Northwest Territories. SSi is also a provider of Satellite Communication services, offered in locations that do not have terrestrial service options. They offer turnkey Internet systems to other ISPs. They have a local market serving all 25 communities in Nunavut and several in the Northwest Territories. These two territories account for 1/3 of Canada's landmass covering 3,439,296 km2 (1,327,920 sq mi). They also have an international market including Africa, Indonesia and Kiribati.
The Internet in Pakistanhas been available since the early 1990s. Pakistan has about 122 million internet users, making it the 8th-largest population of internet users in the world. Information and communications technology (ICT) is one of the fastest growing industries in the country. In 2001 just 1.3% of the population used the Internet. By 2006 this figure had grown to 6.5% and in 2012 to 10.0%. As of July 2021; the percentage of internet users in Pakistan is 54%, which translates into approximately 118 million citizens having access to internet.
Deployment of the Internet Protocol Version 6 (IPv6), the latest generation of the Internet Protocol, has been in progress since the mid-2000s. IPv6 was designed as a replacement for IPv4. IPv4 has been in use since 1982, and is in the final stages of exhausting its unallocated address space, but still carries most Internet traffic.
6rd is a mechanism to facilitate IPv6 rapid deployment across IPv4 infrastructures of Internet service providers (ISPs).
In the field of IPv6 deployment, IPv6 brokenness was bad behavior seen in early tunneled or dual stack IPv6 deployments where unreliable or bogus IPv6 connectivity is chosen in preference to working IPv4 connectivity. This often resulted in long delays in web page loading, where the user had to wait for each attempted IPv6 connection to time out before the IPv4 connection was tried. These timeouts ranged from being near-instantaneous in the best cases, to taking anywhere between four seconds to three minutes.
World IPv6 Day was a technical testing and publicity event in 2011 sponsored and organized by the Internet Society and several large Internet content services to test and promote public IPv6 deployment. Following the success of the 2011 test day, the Internet Society carried out a World IPv6 Launch day on June 6, 2012 which, instead of just a test day, was planned to permanently enable IPv6 for the products and services of the participants.
Link3 Technologies Ltd also known as Link3, is an IT and internet company based in Dhaka, Bangladesh.
