Portal:Internet
The Internet PortalThe Internet (or internet) is the 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. The origins of the Internet date back to research that enabled the time-sharing of computer resources and the development of packet switching in the 1960s. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 1970s by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense in collaboration with universities and researchers across the United States and in the United Kingdom and France. The ARPANET initially served as a backbone for the interconnection of regional academic and military networks in the United States to enable resource sharing. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, encouraged worldwide participation in the development of new networking technologies and the merger of many networks using DARPA's Internet protocol suite. The linking of commercial networks and enterprises by the early 1990s, as well as the advent of the World Wide Web, marked the beginning of the transition to the modern Internet, and generated sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia in the 1980s, the subsequent commercialization in the 1990s and beyond incorporated its services and technologies into virtually every aspect of modern life.

It is one of the world's largest social media websites and the seventh-most visited website in the world. Users can share short text messages, images, and videos in posts (formerly "tweets") and like or repost/retweet other users' content. X also includes direct messaging, video and audio calling, bookmarks, lists and communities, and Spaces, a social audio feature. Users can vote on context added by approved users using the Community Notes feature. Twitter was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams, and was launched in July of that year. Twitter grew quickly; by 2012 more than 100 million users produced 340 million tweets per day. Twitter, Inc., was based in San Francisco, California, and had more than 25 offices around the world. A signature characteristic of the service is that posts are required to be brief. Posts were initially limited to 140 characters, which was changed to 280 characters in 2017 and removed for paid accounts in 2023. The majority of tweets are produced by a minority of users. In 2020, it was estimated that approximately 48 million accounts (15 percent of all accounts) were not genuine people. (Full article...) Selected pictureA wireless LAN or WLAN is a wireless local area network, which is the linking of two or more computers without using wires. WLAN utilizes spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area, also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. News

Selected biography
Terry Semel (born on February 24, 1943 in Brooklyn, New York, U.S.A.) is an American corporate executive who was the chairman and CEO of Yahoo! Incorporated. Previously, Semel spent 24 years at Warner Brothers, where he served as chairman and co-chief executive officer. In June 2007, Semel resigned as CEO due in part to pressure from shareholders dissatisfaction over Semel's compensation (in 2006 - salary $1, stock options worth $70 million) and performance. Semel had earned over $500 million in his tenure at Yahoo, while Yahoo's stock appreciated at 5% per year. In the same period, Yahoo's closest competitor saw stock growth of over 400%. Semel now serves as non-executive chairman and advisor to Yahoo!.
