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. But there are fully equipped computers, right down to the mouse with the keyboard. But unfortunately, so far this type of computer has not received wide distribution, unlike the same netbook.
The main focus of the nettop is considered to be work with documents and the Internet; in fact, for this purpose it was created. Unlike a conventional personal computer, nettops do not imply the possibility of replacing components at home, primarily because of the extremely small size of the computer. The power supply for computers is remote. Otherwise, they are not fundamentally different from an ordinary computer.
Such computers are well suited for office work or work with documents, as well as for studying, especially if Continue reading

PC Recommendations

Now we will consider the question of choosing a personal computer (PC). Immediately it is worth noting that the examples below are taken from the price list of the DNS store (federal network) for January-February 2011.

So if the occupied Continue reading

Video card

A video card is also a graphics accelerator, a computer component responsible for outputting images and generating graphics, for example, in games. The video card is necessary for the computer to work, otherwise it just won’t start, and the picture doesn’t appear. At the moment, there are various types of accelerators, for home systems (desktop), mobile (laptops, communicators and even telephones), for semi-professional and professional use. There are also differences in “acceleration goals”, there are two-dimensional graphics accelerators (2D) and three-dimensional graphics accelerators (3D). 2D accelerators do not always work with 3D graphics, but they are more likely to be semi-professional and professional accelerators; they serve mainly for working, for example, with photography (for example, in magazines that print). But do not think that 3D accelerators do not work with 2D graphics, they work! just focus on 3D. Video cards for home computers are all 3D accelerators.

The main parameters of video cards can be called: graphics processor, type and amount of memory, Continue reading
