what is my ip address and port

What is a port?

Can be to the uninitiated or computer user, and only talented and technical geek-speak to be somewhat frustrating, and aggravating.Fortunately, they are only moments.

Port

Photography Bay where there are a lot of boats are docked. And called the general location of a seaport, literally in port or at sea. Everyone wants to dock thereÑrequesting down servicesÑuses the same port. Ports dealing with numbers assigned individual marina. The name of the port and berth number in the combination of "what and where" to determine the identity of the boat.

Geek speak, and anchored the numbers on the Internet is the Internet Protocol or IP addresses, user ID numerical on the Internet. Depending on the type of connection and service provider, has the user's IP address or remain the same with each connection or for "docking" on the Internet.

Port of the computer is a type of electronic devices, point-docking or programming related software through which the flow of information from the program on your computer or to your computer from the Internet or another computer in the network. (A network, by the way, is a series of computers that are physically or electronically linked.)

In terms of the computer, and a computer program or connecting to somewhere or anything else on the Internet through the port. Port numbers and IP address of the user to combine "who does what" information held by each ISP.

Ports are numbered consistency and programming. Ports most commonly known are those numbered from 0 to 1023 dedicated to the use of the Internet, but it can be extended much higher for specialized purposes. Each group is assigned or port range functions or specialized functions, and this is generally all they do. Normally, all the services matching system functions or used the same port numbers on the receiving servers.

For example, all the computers to access or request a quote from today's always use port 17, because this port is officially reserved for this purpose, and ask only for this service use port 17. The information generated is directed through a different port or private, to preserve "the incoming line" open to others. Receive e-mail on a computer that uses local generally TCP port 25. File Transfer Protocol (FTP) or uses port 21, for example a few port mappings.

TCP / UDP

Stands for Transmission Control Protocol TCP, and UDP is an acronym for User Datagram Protocol. Both related to the transfer of data on the Internet, but it works in a very different way.

TCP is significantly more reliable. It is based connection to transfer data. Must be based on a point between sending the site to receive the site, and the data that is sent A first will always reach the destination before the data sent B II. Transfer the only failure is one that is broken (for example, if the connection point references on the Internet or a web site receiver continuously or e-mail address is no longer valid. Mail server is the point of receiving that counts thereÑnot user name. )

UDP is a connectionless protocol. Data is sent regardless of the state and the recipient. Unfortunately, there is no guarantee that ever that the data contained in the order, or in what condition.

For example, between the two countries may involve two sets of mailing letters. Formation to include letters of 1 and 2. Group A is sent through the postal service called TCP permanent predefined him with no way of derivation. Will Letters 1 and 2 up, and they'll arrive in the system.

At the same time, Group B comprises 3 and 4 messages that have been sent in the days of the time through the postal service, known UDP. Because it was sent with the guidance and instructions of delivery, "to get there when you can in any way may findÑmaybe only do the best you can." Message torn arrive 4 and colored water, bent, folded, and distortion generally well; 3 never appear at all, and never returned to the sender.

Another difference between TCP and UDP takes data stream. Data sets are sent sent via TCP smoothly, and there is no separation between the bits of data that allows for smoother viewing or listening experience.

And ensures the flow of UDP data sets or packages to access, but they do so individually. Slightly delayed, images or sound jerking may lead Rhode each package to come apart, and read, and play. While it seems at odds with the above, the difference is in the data side, "packaging". Not guaranteed bits of data, those individual messages, or to reach in what form. Data packets flowing "in large quantities", and boxes are sent, not envelopes. Data is sent flowing "boxes" along the more reliable, and if you asked, will be delivered. Consider providing higher priority, compared to air travel or ground transportation registered mail for regular mail.

Beginners can previously in geek-speak boast comfortable they no longer take any port in a storm computer, metaphorically, but they know whether you have a program broadcast or receive over a TCP or UDP, which is progress, in fact.
Groups port range

0 to 1023 - from the well-known port numbers. Only private companies, such as Apple's QuickTime, MSN, SQL Services, Gopher services and other services have this prominent port numbers.

1024 up to 49151 - Registered Ports; means can be registered for specific protocols by software companies.

49152 till 65536 - dynamic or private ports; meaning they can be used by almost anyone.
