RAM stands for random-access memory. It is also simply known as memory.



 The size/capacity of the RAM affects how many temporary files can be stored and how fast your computer runs. The greater the amount of RAM, the faster your computer will run (in general). The size of RAM is measured in gigabytes (GB).



The speed of the RAM itself can also affect how fast your computer runs. The speed of RAM is measured in megahertz (MHz).


Number of Slots/Soldered or Not

If you think you may want to increase or upgrade the RAM in your computer, you will want to keep in mind whether the RAM that comes with your computer is soldered in to the computer and how many slots are in your computer. If the RAM is soldered in to your computer, it cannot be replaced or it will need to be replaced by a hardware repair center. If the RAM is not soldered in to the computer, it will be inserted in to slots in your computer. The number of slots in your computer may vary and the number of slots that are being used when you buy your computer may vary. This will affect how much you can increase the amount of RAM in your computer.
