Procesador
At the prior post we saw how the computers are every time more fast due to the increase of density of the transistors linked to its continuous size reduction. By one hand, the augment of transistor allow make more operations by second, and by the other hand, decrease its size allows enhance the clock frequency, but this second way of optimization was stalled at 2003. See why. Continue discovering "Ghz: Why are stalled? "

We can classify the ways that hard disk can breakdown in two: software and hardware. With the first I'm talking about the lost of data due to virus or accidental erasure. In these cases, if it's possible retrieve the information, it is often so cheap because only we have to use the appropriate software. Instead, the errors of hardware or physics are very expensive of repair, because are needed tools and specialized installations and only if the information that contains is enough valuable, can worth pay for it.

Signal warning of radiactivity
The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous. Finish reading "The machines neither are inmune to the radiactivity"

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.
