The communication software is basically the kind of software providing the user with the opportunity to exchange any kind of data through the internet. For this the phone line or the local modem can be used. The information can be literally of any kind and may be provided in the form of text, image, video, audio etc. The users can exchange data by sending it from one PC to another using the ID as the definition of the receiver. There are a lot of special programs nowadays available for easing the data transfer. Some of them are made to load the files even in case of the unstable connection; the others are specializing on sending the encrypted files for more data safety.

The history of the communication software is really long, as it started in early 1965, at this time it was the first try to communicate through the computers linked in one web. At this time the first text chat was created and appeared to be the basis for the further development. It obtained the ability to run the text-format data exchange in between several users at once.

The bulletin board system appeared in the 1970s; ten years later the world saw the first terminal emulator that appeared to be the miracle of those days. It was the sufficient piece of the software created for successful logging into the mainframes as well as to access the e-mail. Before this the computers were all working in the limits of the binary system, so all they could sent was basically the plain text. However the implementation of the new standards opened the variety of the extended possibilities.

Starting from the early 1985 the communication software was developing constantly. At these times the users got first the audio chat and soon the video-camera as well. Also the files for sending started getting heavier and appeared to be in rather various formats. Nowadays a great part of the Internet features is the communication.
