The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite ( TCP / IP ) to serve billions of users worldwide.

The Transmission Control Protocol ( TCP ) is used when the response data size exceeds 512 bytes, or for tasks such as zone transfers.

This type of pivoting is restricted to certain TCP and UDP ports that are supported by the proxy.

Normally, it is also possible to send a push request over UDP to the push proxy which is more efficient than using TCP.

The Gopher protocol () is a TCP / IP application layer protocol designed for distributing, searching, and retrieving documents over the Internet.

When TCP / IP is used, each phone can have one or more IP addresses allocated.

The most notable example of internetworking is the Internet, a network of networks based on many underlying hardware technologies, but unified by an internetworking protocol standard, the Internet Protocol Suite, often also referred to as TCP / IP.

ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications ( with the exception of some diagnostic tools like ping and traceroute ).

* The IPv6 header is not protected by a checksum ; integrity protection is assumed to be assured by both link-layer and higher-layer ( TCP, UDP, etc.

The Internet Protocol Suite is therefore often referred to as TCP / IP.

Transmission Control Protocol ( TCP ) is an example of a protocol that will adjust its segment size to be smaller than the MTU.

It is commonly known as TCP / IP, because of its most important protocols: Transmission Control Protocol ( TCP ) and Internet Protocol ( IP ), which were the first networking protocols defined in this standard.

One popular expression is that TCP / IP, the eventual product of Cerf and Kahn's work, will run over " two tin cans and a string.

Although this market segment is now much reduced, the technologies developed in this area continue to be influential on the Internet and in both Linux and Apple Mac OS X networking — and the TCP / IP protocol has now almost completely replaced IPX, AppleTalk, NBF, and other protocols used by the early PC LANs.

A good example is a server responsible for TCP / IP connections: If this server is restarted, applications will experience a " lost " connection, a normal occurrence in networked system.

Simple TCP / IP messaging ( telnet compatible ) is used to communicate with client sockets, each of which is identified with a ' player ' in the Virtual reality representation system.

A specific stream, analogous to a TCP / IP port or socket, is specified by using a Transport Service Access Point ( TSAP ).

The TCP / IP stack is based on the open source BSD stack as visible with SCCS what compatible tools.

In computing, the Post Office Protocol ( POP ) is an application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP / IP connection.

At the time it was being developed, a full, reliable connection-oriented protocol like TCP was considered to be too expensive to implement for most of the intended uses of AppleTalk.

Its definition presumes an underlying and reliable transport layer protocol, and Transmission Control Protocol ( TCP ) predominates for this purpose.

To transfer data reliably, applications must utilize an appropriate Transport Layer protocol, such as Transmission Control Protocol ( TCP ), which provides a reliable stream.

TCP provides reliable, ordered delivery of a stream of octets from a program on one computer to another program on another computer.

* Transmission Control Protocol ( TCP ), where a reliable virtual circuit is established on top of the underlying unreliable and connectionless IP protocol.

Together, TCP and IP provide a reliable service, whereas UDP and IP provide an unreliable one.

* New TCP / IP Stack: Windows Me includes the Windows 2000 networking stack and architecture which was known to be more reliable, full-featured, stable and offered better performance.

TCP is the more complex protocol, due to its stateful design incorporating reliable transmission and data stream services.

Finally, some transport-layer protocols, for example TCP, but not UDP, provide end-to-end reliable communication, i. e. error recovery by means of error detecting code and automatic repeat request ( ARQ ) protocol.

Historically it has been used primarily with reliable transport protocols such as the Transmission Control Protocol ( TCP ).

The Application Layer protocol SMTP, for example, is concerned about all the details of conducting an email session over a reliable transport service ( usually TCP ), but not in the least concerned about how the transport service makes that service reliable.

* The efficient use of fast but unreliable UDP packets as well as reliable but slower TCP streams.

Some administrators recommend using TACACS + because TCP is seen as a more reliable protocol.

IP fragmentation can cause excessive retransmissions when fragments encounter packet loss and reliable protocols such as TCP must retransmit all of the fragments in order to recover from the loss of a single fragment.

Some of the assumptions of the algorithm can be facilitated using a more reliable communication protocol such as TCP / IP.

The network itself is strictly message-based ( like IP ), but there is a library available to allow reliable streaming communication on top of it ( similar to TCP, although from version 0. 6 there is a new UDP-based SSU transport ).

Originally TCP was designed for unreliable low speed networks ( such as early dial-up modems ) but with the growth of the Internet in terms of internet backbone transmission speeds ( Optical Carrier, gigabit Ethernet and 10 Gigabit Ethernet links ) and faster and more reliable access mechanisms ( such as digital subscriber line and cable modems ) it is frequently used in datacenters and desktop PC environments at speeds over 1 gigabit per second.

It allows for flow-based semantics like in Transmission Control Protocol ( TCP ), but does not provide reliable in-order delivery.

Like RADIUS, Diameter provides AAA functionality but in addition it is made more reliable by using TCP and SCTP instead of UDP.

While it could add security to any protocol that uses reliable connections, such as TCP, it was most commonly used by Netscape with HTTP to form HTTPS.

TCP, the main protocol used in the Internet today, is a reliable unicast protocol.

With reliable protocols, such as TCP as opposed to UDP, the dropped packets will not be acknowledged by the receiver, and therefore will be resent by the emitter, thus generating more traffic.

For this reason, TCP / IP connections are typically either run on highly reliable fiber networks, or over a lower-level protocol with added error-detection and correction features ( such as modem links with ARQ ).
