When choosing a laptop is important to pay attention not only on external characteristics - color, size, weight, but also on technical parameters, which are not always obvious.
There are several ways to find them.
When buying a laptop or netbook, you should pay attention to a number of technical parameters that affect the performance.
Processor (CPU) - the central part of any computer, from it is largely dependent performance of the entire system. Key Features - clock speed and number of cores.
Memory (RAM) on a par with the processor has an impact on performance. The amount of memory measured in gigabytes - the main indicator, but also important clock frequency.
Graphics adapter card or aown processor (GPU) and memory. Performance graphics card is especially important for a gaming notebook. One gets it from the volume and frequency of video memory and GPU frequencies.
On Windows operating systems 7 and 8provided a summary of system performance. It is called the index of performance. Access to the index can be accessed through the Control Panel, select "System".
Hard disk - a device for storing information. It also affects the performance, though to a lesser degree. Important characteristics - interface (IDE, SATA, SAS) - the speed of data exchange depends on it, as well as volume.
How to know the characteristics of
If the labels with the description of the goods, as well as the storyconsultant, are not credible, and to check the characteristics of the laptop on the website the manufacturer is not possible, - some simple commands help you find out everything you need on the spot.
Microsoft says statistics on the proportion of their operating system,equal to 93%, and other agencies (for example, ABI Research) withdrawn Microsoft 70% of the market. Thus, the majority of pre-installed OS laptops are part of Windows.
Laptops tend to sellpreinstalled operating systems. If we are talking of Windows, detailed information about your computer can be obtained by typing in the dialog box "Run" (called the key combination Win + R) command msinfo32.
msinfo32 program.exe collects detailed information about the hardware - manufacturer, device ID and their technical characteristics. Here you can find the version of the operating system, drivers, and services.
Often, the sale can be seen laptops with oneof the GNU / Linux distributions. In this case, to obtain information about the system need to open a terminal - a command line interface and enter the following command:
- Lsb_release -a - will provide the name and version of distributiva-
- Cat / proc / cpuinfo - information about protsessore-
- Cat / proc / meminfo - information about physical and virtual pamyati-
- Lshw - displays details about the hardware.
