RAM, or Random Access Memory, is a type of computer storage, but it's different from the storage you typically think of, like a hard drive or SSD(Solid State Drive or Solid State Disk). 

It's like the short-term memory of a computer. It helps the computer work quickly by storing the information currently needed. When you open programs, play games, or browse the internet, the computer uses RAM to keep everything running smoothly.

You can think of it like a table—the bigger the table, the more things you can put on it. Similarly, the more RAM you have, the more tasks you can handle at the same time without slowing down.For example, if you have many browser tabs open, are running a video editing program, and have a game running in the background, RAM ensures all these tasks run smoothly without slowing down your system.

What do they look like? Below are pictures of the most common RAM DDR desktop memory SODIMM series and laptop memory UDIMM series.

However, note that, as mentioned earlier, RAM differs from permanent storage devices like hard drives or SSDs. RAM is temporary storage, and the data in RAM is erased when the computer is turned off. That’s why RAM is considered volatile memory—it only remains active while the device is on.
