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 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.

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.

In March 1982, the US Department of Defense declared TCP / IP as the standard for all military computer networking.

At the higher layers, the Internet Protocol ( TCP / IP ) has become the standard.

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.

* use of standard protocols and formats, such as TCP / IP, HTTP, and HTML

z / OS can communicate directly via TCP / IP, including IPv6, and includes standard HTTP servers ( one from Lotus, the other Apache-derived ) along with other common services such as FTP, NFS, and CIFS / SMB.

TCP / IP's pragmatic approach to computer networking and two independent implementations of simplified protocols made it a practical standard.

As Ethernet has increased in common use since the 1990s, control signals are now commonly sent between a single UPS and multiple computers using standard Ethernet data communication methods such as TCP / IP.

WAIS did not adhere to either the standard or its OSI framework ( adopting instead TCP / IP ) but created a unique protocol inspired by Z39. 50: 1988.

SLIP modifies a standard TCP / IP datagram by appending a special " SLIP END " character to it, which distinguishes datagram boundaries in the byte stream.

In the mid 2000s, UUCP over TCP / IP ( often encrypted, using the SSH protocol ) was proposed for use when a computer does not have any fixed IP addresses but is still willing to run a standard mail transfer agent ( MTA ) like Sendmail or Postfix.

Later Ultrix-32 incorporated some features from 4. 3BSD and optionally included DECnet and SNA in addition to the standard TCP / IP, and both the SMTP and DEC's Mail-11 protocols.

Many UB products initially used the XNS protocol suite and later transitioned to TCP / IP as it became an industry standard in the late 1980s.

* The standard TCP / IP port number for FTP connection

Remote shellcodes normally use standard TCP / IP socket connections to allow the attacker access to the shell on the target machine.

Applications generally implement Bonjour services using standard TCP / IP calls, rather than in the operating system.

The full TCP / IP standard was not implemented, but the use of Ethernet made it possible to implement the first instances of object management and global data access technology.

In contrast with the Wireless Application Protocol ( WAP ) standard, which used Wireless Markup Language ( WML ) on top of a protocol stack for wireless handheld devices, i-mode borrows from fixed Internet data formats such as C-HTML based on HTML, as well as DoCoMo proprietary protocols ALP ( HTTP ) and TLP ( TCP, UDP ).

E-mail messaging from phones, as popularized by NTT Docomo's i-mode and the RIM BlackBerry, also typically use standard mail protocols such as SMTP over TCP / IP.

Its first service was the " standard dial-up " ( SDU )-full TCP / IP access on a static IP address allowing users to receive SMTP mail and other IP traffic direct to their computers.

* the standard TCP / IP port number for HTTP connections

* I / O ports: Expansion port, tape recorder connector ( 1200 baud variation on the Kansas City standard for data encoding ), aerial TV connector ( RF modulator ), composite video and RGB monitor output

One common replacement for LocalTalk was PhoneNet, a 3rd party solution ( from a company called Farallon, now called Netopia ) that also used the RS-422 port and was indistinguishable from LocalTalk as far as Apple's LocalTalk port drivers were concerned, but ran over the two unused wires in standard four-wire phone cabling.

The effort was sufficiently complete that during the summer of 1973 the Unix kernel for the PDP-11 was rewritten in C. During the 1972 – 73 period there was a need to port to Honeywell 635 and IBM 360 / 370 machines, so Mike Lesk wrote the " portable I / O package " which would become the C " standard I / O " routines.

The Dragon has additional circuitry to make the MC6847 VDG compatible with European 625-line television standards, rather than the US 525-line NTSC standard, and a Centronics parallel printer port not present on the TRS-80.

While Duck Hunt does not have a traditional multiplayer mode, the manual states that a second player may plug in a standard NES controller in the other controller port and control the duck that appears.

For example, a serial port needs to handle standard communication protocols such as XON / XOFF that are common for all serial port hardware.

The cache is retrieved by connecting a device that has a USB port and that is able to read standard text files.

Computer port view of the Atari standard connector: 1. up, 2. down, 3. left, 4. right, 5.

Some computer sound cards include a standard MIDI connector, whereas others connect by any of various means that include the D-subminiature DA-15 game port, USB, FireWire, Ethernet or a proprietary connection.

The standard bootloader for the HC11 family is called BUFFALO, " Bit User Fast Friendly Aid to Logical Operation " ( a BUFFALO prompt seen on the serial port at bootup is a sign that a board's flash memory has been erased ).

The STARTTLS extension allows the use of Transport Layer Security ( TLS ) or Secure Sockets Layer ( SSL ) to be negotiated using the STLS command, on the standard POP3 port, rather than an alternate.

Major improvements were made to key highway links, notably between the coast and the highlands, to provide international standard port facilities at Port Moresby and Lae, and in lesser ports, for international and domestic airport upgradings, and for the regulation and management of transport services.

The " Lombard " appeared in 1999, ( AKA: Bronze Keyboard ) a thinner, lighter, and faster ( 333 or 400 MHz ) PowerBook with a longer battery life and had both USB and SCSI built in and was a New World ROM Mac, and then the " Pismo " in 2000, which replaced the single SCSI port with two FireWire ports, updated the PowerBook line to AGP graphics, a 100 MHz bus speed, and DVD-ROM optical drives standard, in addition to dropping the " G3 " from the PowerBook name.

As the name implied, VQuake was a proprietary port specifically for the Vérité ; consumer 3D acceleration was in its infancy at the time, and there was no standard 3D API for the consumer market.

An RS-232 port was once a standard feature of a personal computer for connections to modems, printers, mice, data storage, uninterruptible power supplies, and other peripheral devices.

For many years, an RS-232-compatible port was a standard feature for serial communications, such as modem connections, on many computers.

XFree86 started as a port of X for 386-compatible PCs and, by the end of the 1990s, had become the greatest source of technical innovation in X and the de facto standard of X development.

XFree86 evolved over time from just one port of X to the leading and most popular implementation and the de facto standard of X's development.

The rear featured a RGB monitor connector ( a standard 9-pin female D-shell compatible with CGA / EGA monitors ), an RCA-style composite video-out connector, a single RCA-style monophonic line-level audio connector, a light pen port, and an edge-card connector used to attach a parallel printer.

The printer port followed the old Centronics standard and was not fully compatible with the parallel port found on PCs.
