First off, let's define RAM. RAM stands for Random Access Memory. It is filled with capacitors that can do two things: temporarily carry or not carry a charge. These capacitors are arranged in banks of 8 hence the binary code (ex. 00001010). Each combination of these "bits" or charges represent a certain data. A collection of these data defines a set of instructions that a computer understands and processes. A RAM therefore, stores instructions (in binary format) for a computer to follow. Why then should we add more RAM to our computer? We use computers because we use the programs/software that assist us in our work (may it be creating an assignment, doing a presentation for our boss, or playing computer games). These programs give out instructions to the computer and the RAM temporarily stores these instructions for processing. Like any kind of storage (ex. bucket), a RAM also gets full.
