Features of a laptop
Buying a laptop or netbook, you should pay attention to a number of technical parameters that affect performance.
Processor (CPU) is the Central part of any computer, it largely depends on the performance of the entire system. Main features — clock frequency and number of cores.
Random access memory (RAM) along with the CPU affects the performance. The amount of memory measured in gigabytes, is the main indicator, but also an important clock speed.
Graphics adapter or video card has its own processor (GPU) and memory. Graphics performance is especially important for gaming laptops. Is it from the volume and frequency of VRAM and GPU.
Operating systems Windows 7 and 8 provides summary information on system performance. It is called the performance index. The access index can be accessed through the control panel, select "System".
Hard drive a device for storing information. It also affects performance, although to a lesser degree. Important characteristics of the interface (IDE, SATA, SAS) - it depends on the communication speed and volume.
How to identify the characteristics of
If the labels with the product description as a story consultant, not credible, and to test the performance of the laptop to the Internet portal of the manufacturer is not possible, simple commands will help you to learn all you need on site.
Statistics Microsoft says their OS share equal to 93%, other agencies (for example, ABI Research) withdrawn Microsoft 70% of the market. Thus, most pre-installed on laptops included in the OS family of Windows.
Laptops typically sold pre-installed operating systems. If we are talking about Windows information about the computer, you can get by typing in the dialog box "Run" (shortcut key Win+R) msinfo32.
The program msinfo32.exe gathers detailed information about your hardware vendor and device IDs and their characteristics. Here you can learn about the version of the operating system, drivers, and services.
Often you can see laptops with one of GNU/Linux distributions. In this case, to obtain information about the system need to open terminal — command-line interface and enter one of the following commands:
- lsb_release -a - will allow you to obtain the name and version of the distribution;
- cat /proc/cpuinfo — information about the processor;
- cat /proc/meminfo - information about physical and virtual memory;
- lshw — displays details about the hardware.
