Nettop Choice

Nettop, like the netbook, was introduced by Intel at the release of the Atom processor. That is, in essence, it is the same as a netbook only in the form of a computer (stationary). In fact, it is an ordinary computer with only less power and price. Packed in a small case. It is also worth saying that the monitor is not always attached to nettops, do not forget about it.

The answer is simple, the need to store more and more operational data is constantly growing and the processor memory (cache) is very small for that, with regards to the hard disk, some data is stored on it, but only a part, the speed of RAM is much faster than the speed of working with hard disk, because RAM is used.

The main characteristics of RAM are: memory type, memory speed, timings, form factor, volume.
Type of memory – with the development of technology and computer technology, more and more types of memory appear, more precisely, newer ones remove old ones from the market. At the moment, DDR3 is common, although so Continue reading
