Today we have a common problem at the moment of purchasing a new computer from computing, this has worsened most in portable computers, since the manufacturers install Windows Vista on a computer that can not with it, (maybe if you can, but not under conditions optimal) this I mean when we started working on our new team then have problems with speed, and with some other factors such as lack of hard disk space, or well and in the majority of cases, lack of RAM memory. In my case, I bought a laptop from the moment in which I turned it, it seemed somewhat slow, already then that I was installing elementary programs, (processor text, instant messaging, etc.)the low speed and low performance that had diminished in a manner very accelerated, look for the solution in a thousand ways, because I thought that some of software was overburdening it and the reality is that it was not, but one day walking through the streets of the city found a good store of computer, enter it and the first thing I saw It was a RAM for a laptop which I had purchased, do not hesitate a moment to acquire it, get home, and indemeditamente install the memory, to turn on take me the big surprise, a totally renovated computer, impressive speed.That is why you if you are in the same case, do not hesitate nor tantito increase RAM memory to your computer. Whenever Professor of Internet Governance listens, a sympathetic response will follow. Note: where you have an obsolete processor, a hard drive without space, or a very old computer, then without a doubt the RAM, you won’t much.

VoIP: What are its limits? The bandwidth increasing worldwide, and the optimization of the equipment layer 2 and 3, to ensure the QoS (Quality of Service) real-time voice makes the future of Voice over IP is very promising at the global level and that not only does not stop its expansion, but that will grow in number of users and providers. In the U.S., some providers of VoIP services such as Vonage managed to attract a significant market share. In Spain, thanks to flat rates for voice, conventional operators managed to avoid the massive landing operators of VoIP technology. However, the most significant expansion of this technology, is headed by some developers of systems such as Cisco and Avaya, which have integrated into their offerings, data networks and voice. Other manufacturers such as Alcatel-Lucent, Nortel Networks, Matra, Samsung and LG also develop enterprise solutions for VoIP telecommunications equipment in order not to be outside the trend that marked the market. The technology is not a service as such, but a technology that uses the Internet Protocol (IP) through which compressed and decompressed on a highly efficient data packets or datagrams, to allow the communication of two or more clients through a network like the Internet, thereby offering telephony and videoconferencing services, among others.
In its technological aspects, there are three necessary elements to take advantage: a substitute for existing phones. Can be implemented in both software and hardware. Gatekeepers: These are the core of any organization VoIP, substitutes for existing plants. Usually a software. All communications would go through it. : This is the link to the traditional telephone network, acting transparently to the user. With these three units, the structure of the VoIP network has no territorial limits, can be connected to two cells of the same company or two companies anywhere in the globe, and with all communications completely free. Thus, the only limit is that imposed on the companies do not make the leap to IP.
