RAM , or Random Access Memory, is the memory storage device employed by your computer for the purpose of being able to save as much as possible on the machine. The amount of RAM on your system is important to know if you are planning on saving numerous large files. DIMM (Dual Inline Memory Modules) are used to hold RAM on newer computers, and they can run on speeds up to 800 MHZ (megahertz). Most computers equipped with Windows come with a capacity of 128 MB, but a user can upgrade this to 512 MB or more. RAM can be bulked up on a computer manually using a Phillips screwdriver and antistatic wrist strap for safety. However, if you're not looking to go digging inside your computer, there are plenty of external computer storage options with removable RAM , which can provide additional hard drive capacity .
External Computer Storage
Floppy Disks: These are rarely used for computers any more, but for older PCs with disc drives , they may still be a storage option.
External Hard Drives: These can come in many different models and range in capacity, up to sizes of 1 TB (terrabyte). These lightweight items are usually the size of a small book and make for good back-up storage.
