Few users know what RAM is. Although almost everyone realizes that we are talking about any component in the computer. Meanwhile, there is an exact decoding.
RAM (or RAM) is a random access memory device, which is popularly called the "RAM". This "RAM" is in any computer, laptop and even phone - without it, no gadget can work. True, for different devices it is required in different volumes, but we'll talk about this later.
The difference between RAM and permanent
Now that the decryption of RAM is known, an important point should be noted. Many beginners confuse random access memory with a constant available on a hard disk, however it cannot be done. There is nothing in common between them. These types of memory have completely different purposes, they also work differently, even decryption is different. RAM is a dynamic memory that requires a certain amount of energy, and when the power goes out, all the data stored inside is lost. A connection to electricity is also required for writing and reading data on hard drives and flash drives. However, to store information on portable devices, electricity is not needed.
How does RAM work?
Decryption to some extent allows us to understand the principle of operation of this element of the system. Random access memory must instantly memorize a data set and give access to them if necessary.
RAM is a complex chipset and modules. If we give an analogy, then in structure it resembles a honeycomb of bees. That is, the computer memory consists of cells that are designed to store data (one or four bits). Each of them is endowed with a specific address consisting of two components - the address of the vertical column and horizontal row (Column and Row, respectively).
The work of memory is closely related to the functionality of the central processor and all devices that are connected to the computer as peripherals. The latter "trust" their RAM information, therefore, the data first goes to RAM (from a hard disk or external media), and then they are processed by the central processor.
Between memory and the processor exchange is carried out directly. Although sometimes there is cache intervention, which is a temporary storage of frequently requested information. Due to its presence, the time of information delivery to the processor registers is significantly reduced.
Control
RAM is controlled by a special controller, which is installed in the chipset of the system board (motherboard). In particular, North Bridge provides the connection of the processor to the high-performance RAM bus.
So, the principle of operation of the entire system with the participation of RAM is as follows: when you turn on the computer from the hard disk to the RAM, drivers and other programs of the operating system are recorded. The programs launched by the user also get there. Then, the recorded data is transmitted to the processor, processed and sent back. All computer work is built in this way.
The system functions as long as the number of RAM cells is sufficient for normal operation. If they do not remain, the role of RAM is taken over by the memory of the hard disk (swap file). Given the lower performance of the drive, its use significantly reduces the speed of system operation, but this does not apply to this topic.
Finally
So, we examined what it is - RAM, how it works and in general what is the role of the specified component in the system. In conclusion, it is worth noting that this module is constantly being improved, its operation scheme can change with the release of new types of RAM, however, the principle is the same always. Perhaps everything looks logical and understandable. This information is even told in educational institutions in computer science. Decryption of RAM in the context of the study of computer technology now no one will raise questions.
