When shopping for new RAM it's important to remember that size isn't everything. More RAM will allow you to multi-task or use larger applications more easily, however RAM is also graded on speed. Higher DDR certifications typically run more quickly, with the exact speed measured in MHz.

It's important to check you're buying RAM that is compatible with your build. The DDR version used of your new RAM must match the version supported by your motherboard, otherwise you won't be able to install it. Your motherboard will also have a maximum amount of RAM supported - double check you have enough free slots before buying an extra stick of RAM.

What is the RAM in a computer?

RAM stands for random access memory, a form of volatile memory that stores information temporarily. This can be retrieved from your system's RAM, which is much quicker than reading data from the hard drive. Once an application no longer requires this information, or the system is shut down, this information is discarded and the RAM can be reused.

What is the function of RAM?

RAM is essentially a form of high-speed, short-term memory for your system - it temporarily stores all of the data it thinks your computer might need in that moment or the near future. This means when an application or user requires this data, the system can retrieve it more quickly. Modern operating systems often pre-cache applications and data in unused RAM to improve system responsiveness.

What is ROM and RAM in computer?

The essential difference between ROM and RAM is their core purpose - RAM is intended for temporary storage in order to speed up computing processes, and therefore needs power to retain information.

ROM, including hard drives and SSDs, is non-volatile, meaning these formats store data over the long-term. Read Only Memory is necessary for storing important files, programs, and the operating system when they are not in use, so that these can be restored at a later date.
