Skype - Calling Without Pay

Skype was a communication program with technology P2P (peer to peer). This program was the free program (could diunduh free) and was made with the aim of the provisions of means of voice communication (voice) was of high quality that was cheap had the internet for everyone in various parts of the world as a base. The user Skype could speak with the user Skype other free, contacted the traditional telephone at a cost of (skypeOut), accepted the call from telephoning traditional (SkypeIn), and accepted the message of the voice [1]. Only in several years in April 2006 Skype had 100 million users. In the matter of the quality of the better voice, this possibly happened because of the team of the Skype work was successful Controlled resources- resources that were available in the network. So as to increase the success of the call and the quality in the Skype network exceeded the POTS level (Plain Old Telephony System: the Telepon Tua Biasa System) without using the concentration of expensive resources. By simplifying his software, this system enabled pengaplikasian that found it easy by who. Most of the sender-recipient the instant message (Instant Messenger) or communication software needed the form of the seeker's data was focussed that had a purpose so that relations between the user of the end succeed in being carried out, where the users of this end had the name of the static user because of his IP address tended Changed. This change happened during the user moved the location or tried to connect himself back to in the network by using the IP address dynamic. Most of the communications equipment that had the internet as a base, look for and found his user used the centre of information (central directory) where each name of the user and the number IP him was recorded and find out whether each user was in the network (online) or not. The centre of this information very much big his cost when his user improved as far as millions, by decentralising the infrastructure that ate many resources, skype succeeded in focussing his resources to develop the function. In the cover (the call break) as minimally as possible. By using all the available resources, Skype could aim cleverly the call call that terkode went through all the effective route that possibly was passed through. Skype in fact confirmed various connecting routes continued to be open and to dynamically move chose the best route at the time. This made Skype immediately became attention of the person because of his impact in reducing the continuation break and the increase in the quality of the call in the network. Each call and the instant message was encoded by Skype on the end one and other to protect the user's privation. This coding necessary because of all the call/the exchange of information was distributed used internet facilities for the public. This is susceptible to the deception and other crimes. 2. The big capacity. Skype eat 23MB the capacity hardisk when put on, compared with the sender the other instant message like Yahoo that eats the capacity is smaller around 10- 15 MB. 3. Terhalang by time and the person's willingness that call and that is called. The use skype with the voice method must be carried out with the plan beforehand as making the promise with the person that dituju, because if the person that dituju am not ready (terhalang by the difference of time or the continuation difficulty of the internet) then the intention of carrying out communication immediately through the voice can be still being in vain.
