Are you a multi-tasker? Do you usually have multiple applications running at the same time? Do you play massive games that feature hundreds or even thousands of individual characters? If you are one of these people and your laptop typically slows down in these circumstances with extremely delayed response time and your hard drive LED light is blinking constantly, then you'll definitely want to add extra memory to your laptop or upgrade what you currently have .
The type of memory that's being referred to here is the main memory in your computer, also known as RAM (random-access memory). The RAM inside a computer is essentially its workspace. It's the "area" where the computer temporarily stores all the data, applications, and other things it's working with at any given moment. Therefore, the more memory, or the larger the "workspace," the more applications you can run simultaniously. The system can temporarily store a greater amount of data and make it easily available for access, which allows the processor and other hardware to access information faster. However, the performance of the memory must also be taken into consideration. Faster memory allows more data to be transferred at once at any given moment.
It is very important to have a significant amount of RAM, as well as quality RAM, because RAM is a great deal faster than any other type of storage device (such as hard drives) when utilized as memory. RAM is even more significant in laptops, because laptops typically have hard drives that are even slower when compared to desktop PC hard drives. Plus, having more memory in your laptop will probably help to extend its battery life because the system can communicate with the memory more often than with the slower hard drive (hard drives activity actually consumes more power).
