This is true for spreadsheets, text documents, web pages and video streaming. When you're working on the file, however, the latest data is stored in RAM for faster access. When you are not working on this document or click save, the most recent copy of this file is saved to your hard drive for long-term storage. So now we know what RAM is and that these devices on your PC's motherboard are system RAM and act as short-term memory, but what does this all mean in practice? Well, when you perform actions on your computer, like opening a text document, it requires access to the data contained in that file. One of the reasons for memory standardization across the industry is that computer manufacturers need to know the electrical parameters and physical form of memory that can be installed in their computers (and it makes you buy new memory, but this is something that happens everywhere). These physical differences are standard across the memory sector. To prevent users from inserting incompatible memory, modules are physically different for each generation memory technology. Components are generally created to the highest standard at the time of manufacture, but with the expectation that technology will continue to change. There are ways to see if your computer needs more memory, and be sure to buy memory compatible with the other system components. In other words, it's no use putting 16 GB of RAM memory if the rest of your system is not compatible with that amount of RAM. But at the opposite end, you can install a lot with little or no added benefit. If your system is low on RAM, it may be sluggish and have difficulty doing multiple tasks at once. The speed and performance of your system is directly related to the amount of RAM installed. In other words, RAM would be your “short term memory”, the one you'll access at all times to remember things quickly, and HD is your “long term memory”, meaning the one where you'll store everything else. Hds (Hard Drive) and SSDs (Solid State Drives) are also important components and will help your system reach its peak performance. The more programs your system is running, the more you will need. It stores the information your computer is currently actively using so it can be accessed quickly. RAM gives applications a place to store and access data at short notice. Your computer's random access memory (RAM) is one of the most important components in determining system performance. However, you can get RAM for notebooks (especially for gaming models) with heatsinks.

Also, unlike modern PC cases with transparent sides, people rarely see the inside of a notebook. Laptops, in turn, tend to have more basic RAM memories, as space concerns are fundamental. However, unless you are a powerful overclocker, what matters is the appearance (and making them easier to install). They have a sleek case that doubles as a heat sink. In the image above, you see modern RAM devices for desktop PCs. But then what is RAM? RAM stands for Random Access Memory, and if you've ever opened a notebook or desktop computer, you've seen it.
