Choosing a Laptop

The first thing I want to say is not to confuse laptops with netbooks. Unfortunately, in the price lists they are all under the name of laptops, but it’s good that not all. They differ, as a rule, in weight, for laptops it is from 2 with a small (somewhere 2.2-2.4) kg or more. Netbooks weigh closer to 1kg. Also, for laptops, the screen size starts from 12 inches, respectively, for netbooks up to 12 inches.

So, let’s get back to choosing a laptop. Whether you buy it or not, it depends only on you, but it is worthwhile to analyze a bit the reasons and goals of the purchase. There are always only two reasons: 1) need, for example, is necessary for work; 2) I just want to, this is also not a rare phenomenon, i.e. this is 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
