As you probably know, your computer has a RAM, which is the hardware element of the device that allows you to perform tasks at the same time, and therefore, the higher it’s capacity, the more processes we will be able to develop simultaneously. Outside of this, not everyone knows the different types of RAM that exist, so then we will review them:
Types of RAM
Although the most common RAM these days we could say is the DDRAM, we must not lose sight of the fact that there are two large groups of these components, called SRAM-Static Random Access Memory- and DRAM -Dynamic Random Access Memory-.
The main difference between the two is that SRAMs are static memories and DRAMs are dynamic memories.
Some time ago, SRAMs were more common than DRAMs, but then they took over the market. Today, DDRAMs, which of course are more powerful than DRAMs, are preferred by the most demanding users.
At least, this is what we should keep in mind when it comes to desktop computers.
Meanwhile, in laptops, we have other types of RAM, those of RIM modules, and there are also more varieties, so let’s analyze them:
FPM: it is a memory that was used in models 386, 486 and the first Pentium, with a minimum speed.
EDO: they are the next step in this segment, and these computers began to be used in the Pentium and Pentium 2.
BEDO RAM: the evolution of the previous ones. They tried to compete with the SDRAM but were unsuccessful.
SRAM: They stood out for their very good speed and lower consumption compared to the predecessors, although they were not cheap at all.
SDRAM: unlike the other memories, it synchronized with the processor clock, minimizing waiting times.

RDRAM: here we already have much faster transfer speeds. It was the memory used in the Nintendo 64, in fact.
DRAM: it is a dynamic RAM. Its name refers to the operation of its integrated circuit.
DDR RAM: they were created to double the speeds of the DRAM. Its capacity limit was 1 GB.
DDR2 RAM: here the limit already reaches 2 GB, while the clock speed, even with a lower voltage, has greatly improved.
DDR3 RAM: the third generation of DDRs substantially improved the previous model.
DDR4 RAM: the fourth generation of the same RAM system. They are the most used for their excellent quality/price ratio.
DDR5 RAM: the latest generation of these memories. They double the speed of the previous ones and are up to 20% more effective.
