Transmission Control Protocol

Transmission Control Protocol
Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another. HTTP, HTTPS, SMTP, POP3, IMAP, SSH, FTP, Telnet and a variety of other protocols are typically encapsulated in TCP. Historical origin[edit] In May 1974 the Institute of Electrical and Electronic Engineers (IEEE) published a paper titled "A Protocol for Packet Network Intercommunication."[1] The paper's authors, Vint Cerf and Bob Kahn, described an internetworking protocol for sharing resources using packet-switching among the nodes. Network function[edit] The protocol corresponds to the transport layer of TCP/IP suite. TCP is utilized extensively by many of the Internet's most popular applications, including the World Wide Web (WWW), E-mail, File Transfer Protocol, Secure Shell, peer-to-peer file sharing, and some streaming media applications. TCP segment structure[edit] A TCP segment consists of a segment header and a data section.

Anonymous dupes users into joining Megaupload attack News January 20, 2012 02:29 PM ET Computerworld - The Anonymous hacking group recruited unwitting accomplices in Thursday's attacks against U.S. government sites, a security researcher said today. Internet Protocol This article is about the IP network protocol only. For Internet architecture or other protocols, see Internet protocol suite. The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. Historically, IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974; the other being the connection-oriented Transmission Control Protocol (TCP).

Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names, which can be easily memorized by humans, to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Mises Institute Libertarians often cite the internet as a case in point that liberty is the mother of innovation. Opponents quickly counter that the internet was a government program, proving once again that markets must be guided by the steady hand of the state. In one sense the critics are correct, though not in ways they understand. The internet indeed began as a typical government program, the ARPANET, designed to share mainframe computing power and to establish a secure military communications network. Of course the designers could not have foreseen what the (commercial) internet has become. Still, this reality has important implications for how the internet works — and explains why there are so many roadblocks in the continued development of online technologies.

Van Jacobson Van Jacobson in January 2006 Van Jacobson (born 1950) is an American computer scientist, renowned for his work on TCP/IP network performance and scaling.[1] He is one of the primary contributors to the TCP/IP protocol stack—the technological foundation of today’s Internet.[2] Starting in 1985 he was an adjunct lecturer in Computer Science at the University of California, Berkeley. Early life and education[edit] Jacobson studied Modern Poetry, Physics, and Mathematics and received an M.S. in physics and a B.S. in mathematics from the University of Arizona.[3] He did graduate work at Lawrence Berkeley Laboratory.[4]

Project Chanology Protesters in Guy Fawkes masks outside a Scientology center at the February 10, 2008 Project Chanology protest. The project was publicly launched in the form of a video posted to YouTube, "Message to Scientology", on January 21, 2008. The video states that Anonymous views Scientology's actions as Internet censorship, and asserts the group's intent to "expel the church from the Internet". This was followed by distributed denial-of-service attacks (DDoS), and soon after, black faxes, prank calls, and other measures intended to disrupt the Church of Scientology's operations. In February 2008, the focus of the protest shifted to legal methods, including nonviolent protests and an attempt to get the Internal Revenue Service to investigate the Church of Scientology's tax exempt status in the United States.

Did Al Gore Claim He Invented the Internet? Claim: Vice-President Al Gore claimed during a news interview that he "invented" the Internet. Origins: Despite the derisive references that continue even today, former Vice-President Al Gore never claimed that he "invented" the Internet, nor did he say anything that could reasonably be interpreted that way. The "Al Gore said he 'invented' the Internet" put-downs were misleading, out-of-context distortions of something he said during an interview with Wolf Blitzer on CNN's "Late Edition" program on 1999. When asked to describe what distinguished him from his challenger for the Democratic presidential nomination, Senator Bill Bradley of New Jersey, Gore replied (in part):

TCP congestion-avoidance algorithm Transmission Control Protocol (TCP) uses a network congestion-avoidance algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, with other schemes such as slow-start to achieve congestion avoidance. The TCP congestion-avoidance algorithm is the primary basis for congestion control in the Internet.[1][2][3][4][5] Naming history[edit]

Reaction to aids toddler About Pool’s Closed is a catchphrase associated with a series of raids carried out by Anonymous against the online social networking site Habbo Hotel, where members of the group formed human blockades to obstruct the entry points of popular hangouts with their avatars dressed in afros and business suits. The first raid was launched in July 2006 after rumors began to spread on 4chan that some Habbo moderators had tendencies to ban users based on the skin colors of their avatars. Origin
