In order to consciously choose a computer, you need to have an idea of all the parameters that affect the choice. One of these parameters is the computer's RAM. This resource has several names: RAM, RAM (random access memory) or RAM in the English version. And yet, what is computer RAM? This is a special high-speed memory for temporary storage of information. Its feature is high speed and limited storage time: all data is erased when you restart or when you turn off the computer.
Computer
RAM is often called a random access device. This means that the processor receives information from RAM, regardless of its location in this device (from an arbitrary point).
Each running program uses a piece of RAM to store information. And if all (or almost all) of the memory is occupied, then the PC or laptop "slows down" and "freezes", that is, its work slows down. Therefore, the computer's RAM affects the speed and the number of programs that can be launched simultaneously. If you
If you plan to use only text editors, a browser for
surfing the Internet and several simple games, then you should not worry about the amount of RAM. If the games and programs are resource-intensive, you will have to delve into the capacity of the system.
The amount of RAM installed on the computer depends on the capacity of the system. If the system is 32-bit, then you should not install more than 3 GB of RAM. You can put more, but only 3 GB will be used, the rest of the memory will not be used. With a 64-bit system, the amount of RAM can reach 9 GB, respectively, a computer with such a system is a more powerful device that can "pull" a few
"heavy" programs.
RAM differs in frequency. Today, there are three types of RAM: DDR has a frequency of 200 to 400 MHz, DDR2 - from 533 to 1200 MHz and DDR3 with frequencies from 800 to 2400 MHz. The higher the frequency, the higher the speed. But you just can’t buy the fastest RAM. The choice of device depends on the motherboard (which memory is compatible with the motherboard is indicated on the package).
RAM for the computer is volatile. This means that when the power is turned off or briefly lost, all data from RAM disappears. Sometimes this property is used to restore the system. Due to the large number of running or running programs, the computer's RAM is overloaded, which significantly slows down the work and increases the reaction time to commands. Therefore, having previously saved the necessary data, the system is overloaded. In this case, the contents of the RAM are cleared (cleared), and the computer's performance is restored to a certain point until the RAM is filled again. If this situation repeats often, it is time to either increase resources or change the computer. Every day, programs use more and more resources, and recently very "lively" systems can not cope with the load.
