This week we were learning about the components inside a computer and what they do. My two friendly students in the picture were demonstrating what happens when the computer is switched on. In this 'scene' the OS (Operating system) is being loaded into the RAM, so it can be accessed and used much more efficiently.
We figured that, as Operating Systems become more complex, computers will need more RAM to allow it to be used. Similarly, applications are becoming more powerful too, so they will need more RAM in order to function.
