What is memory for? What the component can do

As soon as you look at the description of a PC or similar device, you will notice that the RAM is listed with various specifications. To help you assess whether the component meets the requirements you have for the device, we have summarized the most important facts for you.

What you should know about RAM

An important component for any device that processes data is RAM.

1. When you read the description of a device, you should look for the abbreviation RAM. This stands for "Random Access Memory" and is the general term for working memory.
2. Working memory is closely linked to the CPU and ensures that the necessary data can be retrieved at any time.
3. Every program you use deposits data in your working memory, which is temporarily stored in it. This is necessary to ensure smooth operation and processing of the data.
4. Your data is stored in memory cells in the working memory, where each cell can capture about one byte. Due to this, the specification of how many GB your RAM can hold is very important.
5. A part of the working memory is used to secure the cache and ensures that the processor can access it directly. In this case, all data is only backed up for a short time and continuously updated.

Then why is a hard disk still needed?

The hard disk is used so that you can store the data of the working memory there. By relieving the working memory in this way on a regular basis, you ensure that the working speed is maintained.
