Some of these port numbers are standardized to provide well-known services. A port number identifies a particular service or process that the server provides. The IP address is generally shown in 'dotted quad' format, with decimal numbers separated by periods, for example '209.86.105.231'.

The IP address consists of 4 bytes that identify a server on the Internet. Within TCP/IP, a communication endpoint is defined by an IP address and a port number.

The Transmission Control Protocol (TCP) provides a means of reliable transport and error checking for the IP datagrams. The Internet Protocol (IP) part of TCP/IP involves packaging data into 'datagrams' that contain header information to identify the source and destination of the data.

Sockets are generally, but not exclusively, used in conjunction with the Transmission Control Protocol/Internet Protocol (TCP/IP) that dominates Internet communications. The API developed there is now known as the 'Berkeley socket interface.' Therefore, if you want to access the information of how an application or the systems window has been structured, download GetWindowText.Sockets are a concept developed at the University of California at Berkeley to add network communication support to the UNIX operating system. The options offered by GetWindowText aren't many, and the two most important of them are the possibility to be able to view the application's window always on top and to minimize to the system tray instead of closing the application. Simply click and drag the GetWindowText icon to the window that you want to obtain the information about. It is only necessary to mover the mouse to be able to access the information in which you are interested.Because it is portable and thus doesn't require to be installed to use it, you will only have to extract the executable from the compressed file in the folder of your choice.When it comes to programing an application you may be interested in access the structure that has been used for the window or another program or menu, and to access this information you can use GetWindowText.
