Random access memory (RAM) is one of the most important elements of a modern personal computer. The characteristics of the RAM cards directly affect the overall performance of the PC.
The main purpose of RAM is to store temporary data used by the central processing unit to perform certain tasks. It should be noted that RAM is a volatile type of memory. The data stored in the RAM cards are available only when the computer is turned on.
RAM cards have much faster read, write and transfer speeds than hard drives. It is customary to consider the following characteristics of a computer's RAM: clock frequency and volume. The amount of RAM affects the amount of data that can be simultaneously stored on the memory cards. Naturally, the more information each board can simultaneously carry, the less time it takes to rewrite it. The presence of cards with a large amount of memory improves the performance of the computer.
The frequency of operation of the RAM cards affects the speed of information exchange between the memory cards and the central processor. This is a very important indicator because boards with a large memory capacity, which do not have a high data transfer rate, cannot work fast enough under certain conditions. All data and commands required by the central processor to perform operations are stored in the computer's RAM.
There are two types of random access memory: dynamic and static. Memory of the first type is relatively slow. It is used to create RAM cards that are connected to specific slots on the computer's motherboard. This type of memory is relatively inexpensive to manufacture.
Static memory is used to create ultra-fast RAM. In a personal computer, it is found in the form of elements of the memory cards and the central processor. It is worth noting that the CPU has its own memory of a static but not dynamic type.
