How does computer memory work?
Computer memory is the short term, high speed storage of a computer. A good example of the parts of the computer: You = CPU your computer desktop = memory your computer desk drawers = hard drive You only have so much usable surface are on the top of the desk so that is constantly being cleaned off (removed from memory) because you can’t read papers underneath other papers, and stuff that is not immediately needed is put into the drawers (hard drive). It’s all matter of give and take – memory (desktop space) is at a premium (costs way more than the space on a hard drive) but getting stuff from the drawers is slow so you want the most used stuff on the desktop (in memory.) Trade-offs are necessary. Each program and piece of data takes space, either in memory or on the hard drive. Computer memory consists of rows and columns of tiny transistors (junction nodes) where electrical energy is at a certain level or it’s at zero –
