Laptop Buying a laptop or a netbook, you should pay attention to a number of technical parameters that affect performance.

processor (CPU) - the central part of any computer, from him is largely dependent on the performance of the entire system.Main features - the clock speed and number of cores.

RAM 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 or video card has its own 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 frequency. operating systems, Windows 7 and 8 provides a summary of system performance.It is called t
he performance index.Access to the index can be accessed through the Control Panel, select "System."

often can be seen in the sale of laptops with one of the distributions GNU / Linux.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 the distribution;

- cat / proc / cpuinfo - information about the CPU;

- cat / proc / meminfo - information about the physical and virtual memory;

- lshw - displays details about the hardware.
