Guide To Build Your PC: How Does Ram Work And How To Select It?

One of the elements that most generates conflict among users who decide to assemble a computer is RAM, as it is an element that has a huge number of variants both in brands to buy, as well as in capacity, speed and latencies in which they can be used. find . These are concepts that most ignore and in this guide we are going to explain how this kind of memory works broadly, what factors you should take into account when buying it and that your system does not have any problems due to compatibility issues.

What is a RAM memory?

RAM is a type of memory dedicated to being the intermediary between the processor and the storage found in the computer. Its main function is to temporarily store the most common instructions and data of the programs that run in the operating system. This type of memory can be found in almost any electronic device, from smartphones to desktop computers and its name comes from its acronym in English: Random Access Memory or Random Access Memory.

This type of memory has certain characteristics that differentiate it from other elements of the computer. The main one is that it is an incredibly fast memory and non-linear work sequences. True, it is not as fast as the processor, but it is fast enough to bridge the files and instructions found on a hard drive or solid state drive, manage them, and then deliver them to the CPU in a matter of nanoseconds.

As in the other guides, we are going to talk with analogies. In this case, RAM memory would be the system of muscles in a body: the more memory, the more speed and less latency , so the system will perform better in the different environments generated by the programs used.

How does a RAM work?

The way this component works is quite similar to that of the processor, this being the one in charge of managing the operation of the RAM with a controller inside the CPU through incoming and outgoing electrical signals. Both manage data from storage and other peripherals to later be processed and released to a graphical environment on the PC monitor.

The signals that the RAM receives are of three types: addressing, data and control signals, which are received through the different buses (or data channels that are integrated into the motherboard). For memory operation, three buses are needed, named after the signals that are received.

The first is the address BUS, it is dedicated to giving specific instructions, locating the data and positioning it in the different memory segments available on the physical stick. In the case of modern memory, DDR4, a maximum of 17 bits is used to establish a maximum capacity limit of 32GB maximum per module installed on the motherboard.

The second BUS is the control BUS, which is dedicated to reading and writing the data and addresses that are sent between the storage and the processor.

The third is the data BUS; This system of connections is where the information used by different programs and memory controllers is stored. This bus also tries to match the bandwidth of the processor with that of the RAM in order to execute faster the tasks indicated in the software.
