How to understand all the different types of memory that are invading our PCs.
The YouTube channel Branch Education specializes in educational videos with a certain talent. Videos that are neither too long nor too short to explain how a CPU works, or the process involved in its manufacture. Many videos are available on the channel, but we'd like to draw your attention to the latest one published by its promoters: a video perfectly in tune with the times, at a time when memory issues have considerably increased the cost of computers and tablets, thanks to the insatiable appetite of artificial intelligence in this area.
Available above or via the following link, this new sequence starts by making a clear distinction between the machines of the 80s and 90s and the computers of today. Today, there are many different types of memory, each with very different technical specifications for equally different purposes: DRAM, for example, found in our memory sticks; NAND, which finds its place in SSDs; cache, which considerably speeds up our processors; registers, which are one of the first steps in the operation of these same processors; and many more besides.
Some types of memory are designed for maximum responsiveness, while others focus on bandwidth, and some - the slowest, but also the least expensive - are dedicated to storage. We invite you to take a look at this highly informative video, which is unfortunately only available in English. Subtitles can be added, however, and an automatic translation - imperfect, but still useful - is also available.
