Im wondering how can a piece of silicon nanometers wide have data that can be read. how can computers recongize mangnets in a hdd. man its fascinating.

Let's go back to the beginning of computers. They were about the size of a room, and people would move circuits around with vacuum tubes. Creating an electronic pulse at one end of a circuit could go through a series of pathways and switches, and through logical circuitpaths achieve a desired result, such as light up a green or red light. These circuits got way more complex with switches such stuff, so eventually RAM was made to deposit temporary data into that could be accessed. This allowed one uniform circuit path to perform calculations on many types of data, instructed by the RAM, rather than being justified to one exact task.

The microprocessor is just a bunch of logical circuits in a small chip that use transistors, or switches made of silicon, to either let or not let electricity pass through. These transistors are basically switches to perform calculations on binary code, sent by the RAM or an input.

It is so darn complex. I feel like I know quite a bit but yet so little at the same time. People study this stuff for years, it's not just like an "ah-ha!" moment.
