A modern computer is the most complex device that has incorporated the advanced achievements of scientific and technological progress. One of the most important components of any computer is its RAM.
The computer has two types of memory: permanent and operational. Constant is characterized by the fact that all data is recorded on a storage medium - a hard disk. When you turn off your computer, all data saved on your hard drive remains intact. The situation is different with RAM - information is stored in it only while the computer is running. Why is RAM needed? First of all, this type of memory is very fast, it takes the operating system much less time to access it than when accessing a hard disk. In addition, it is in the RAM that running programs are saved. Open the Task Manager (Ctrl + alt="Image" + Del) and look at the "Memory" section - you will see the amount of RAM occupied by the currently running programs. As programs run, the amount of memory they occupy can change; the more RAM your computer has, the more efficient it will be. True, the 32-bit version of the Windows XP operating system does not support more than three gigabytes of memory. Its 64-bit version supports up to 128 gigabytes of RAM, but in reality, in this case, everything depends on the capabilities of the motherboard. Windows 7 operating system in 32-bit version supports 4 gigabytes of RAM. In its 64-bit version, the size of the supported RAM depends on the OS version: in the initial ones - Home Basic and Home Premium - it is 8 and 16 gigabytes, respectively, the Professional, Enterprise and Ultimate versions support up to 192 gigabytes. Of course, here the actual supported memory capacity will largely depend on the capabilities of the motherboard. The type of RAM is also important: SIMM, DIMM, DDR, DDR2, DDR3. The first two are already very outdated, so it's hard to come across them. The remaining three types are installed on most modern computers. The more up-to-date the memory used is, the faster it works. Memory chips are assembled into modules, they are also called strips. Modules are installed in dedicated slots on the motherboard.
