HD break apart
A lot of people have only one partition in the hard disk where is the operating system, the virtual memory paging file and their personal files, because is as usually comes a computer newly purchased with Windows. Often I surprise discover the quantity of technical and people, that say be expert without having basics knowledges of the topic, that recommend have only one partition because, according to them, the hard disk works faster, when really is the opposite. Do you want to know why? Surprise yourself with the rest of "Partitions of the hard disk. Are good or bad?"

The travelling salesman is a problem computationally expensive to calculate. Its complexity is exponential and, therefore, is in the category of the problems that can't be solved in a polynomial time, in other words, it's as say that an actual computer can take a lot of millennia in get the solution to the problem. If we can get the result in less time will be useful to salesmen, transport agencies, postmen, distributors, infinity of fabrication process, DNA analysis and a lot of more situations.

Phosphorus of a CRT screen
The screensavers, theoretically, serve to protect the monitors from the deterioration of the quality of the screen produced when you leave an image fixed during a lot of time.

Cable
In the prior post I didn't explain some interesting facts about the submarine cables. ¿How is possible its installation on the oceanic ridges? ¿From where comes the electrical source of the repeaters? ¿What occurs when the deep doesn't allow bury the cable? All these questions and a lot of more will be reveal in this post. Follow discovering "The impressive submarine cables (second part)"

Internet allows that any computer cans communicate with any other computer independently of the distance. This is not magic but is thanks to large cables buried in the seabed that ply the seas and oceans around the world. ¿Do you want know the technology of these cables?

Turing test diagram
Today I woke up philosophical so I'm going to explain the famous Turing test.
The Turing test was proposed in a scientific paper called "Computing Machinery and Intelligence", wrote by Alan Turing in 1950. This is a test that must surpass a machine in order to show that it is intelligent. Read more of "The Turing test and the Chinese room"
