Today I'm going to dedicate the post to explain some basic concepts about the files that the 99% of the people that use a computer don't understand it very well.
Some users know that the last letters that there are at the end of a file (the extension), identifies the type of file, so, for instance, an archive ended in .JPG is a type of file of image and another ended in .GIF is a different image format with other characteristics. This, is true for most cases, but causes confusion in the cases where the extension isn't of a concrete format, unless of a format container. Surprise yourself with the rest of "Differences between extension and format in a file"

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. Don't left of read the rest of "The travelling salesman problem"

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?

embedded cpu
Although your car doesn't have onboard computer, probably it has more than 40 embedded processors. These are less powerful than the PC processors, but enough to perform the work that must accomplish to safeguard our security, improve the efficiency of the vehicle and reduce the pollution that generates. Surprise yourself with the rest of "Your car is full of processors"
