We have talked about disk space and its definition on a different device. However, many users doubted if the disk space was the same as memory. Let's continue to learn.

Disk Space VS Memory: What's Their Difference

Memory and disk space are two confusing terms in the computing world. To understand how a computer works, you must first understand the difference between memory and disk space.

Disk space refers to how much space is available on your hard drive to store files. When you install a new program or download a program, it is stored on your hard drive. The more files/programs you download, install or save on your hard drive, the fuller it becomes.

However, on the other hand, memory is not the same as disk space. Memory refers to RAM (random access memory) inside your computer. RAM is made up of small chips, also known as memory modules. Your computer uses memory (RAM) to store the programs that are running on your computer, including the OS. For instance, the operating system's interface and other processes are loaded into memory when the computer starts up. It is also loaded into computer memory when you open a program such as Microsoft Word. When you exit a program, the memory is freed for other use.

Accessing RAM is much faster than a hard drive, and that is also the reason why active programs are loaded into RAM. Since only a small amount of data from the hard disk needs to be loaded into system memory at a time, computers usually have much more hard disk space than memory. For example, a computer in 2012 might have a 3 TB hard drive and only 16 GB of RAM.

When there is not enough disk space to install a program, you will need to delete unnecessary files from your hard drive or purchase another hard drive. When there is not enough memory to run a program, you will need to upgrade the memory by purchasing more RAM. Click the link below to learn more about RAM:
