RAM

RAM, or Random Access Memory, is a type of computer memory used to store data that the CPU (Central Processing Unit) needs quick access to in order to perform tasks. It is often referred to as the computer’s short-term memory because it temporarily holds data that is being actively used or processed by applications and the operating system.

What RAM is Used For:
Multitasking: RAM allows your computer to run multiple applications simultaneously without slowing down. For example, you can have a web browser, word processor, and music player open at the same time.
Quick Data Access: It stores data that the CPU frequently needs, such as the code and data of currently running applications. This makes the retrieval and execution of instructions much faster compared to accessing data directly from a hard drive or SSD.
Improving Performance: More RAM can help improve overall system performance by reducing the need for the computer to use slower storage methods, such as the hard drive, to manage running applications.

When the system runs out of RAM, it starts using virtual memory on the hard drive, which is much slower, causing a noticeable decrease in performance. Thus, having enough RAM is crucial for smooth and efficient computing, especially for resource-intensive tasks like gaming, video editing, or running virtual machines.
