Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
Internet access is a facility or service that provides connectivity for a computer, a computer network, or other network device to the Internet, and for individuals or organizations to access or use applications such as email and the World Wide Web.
In 1984, the U.S. Census Bureau began collecting data on computer and Internet use in the United States; their first survey showed that 8.2% of all U.S. households owned a personal computer in 1984, and that households with children under the age of 18 were nearly twice as likely to own one at 15.3% (middle and upper middle class households ...
The history of the Internet originated in the efforts of scientists and engineers to build and interconnect computer networks.The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
A further evolution is the 3.5G technology HSDPA, which provides speeds of multiple Megabits per second. Several of the mobile network operators that provide 3G or faster wireless internet access offer plans and wireless modems that enable computers to connect to and access the internet. These wireless modems are typically in the form of a ...
This phenomenon has led to the rise of the Internet of Things (IoT), [127] where modern devices are connected through sensors, software, and other technologies that exchange information with other devices and systems on the Internet. This creates an environment where data can be collected and analyzed instantly, providing better insights and ...
High-speed internet access for computer-based data applications such as broadband information services and interactive entertainment is pervasive. Digital subscriber line (DSL) is the main broadband telecom technology. The fastest growth comes from (value-added) services delivered over mobile networks. [1]
