Why do many studies compare the nervous system to a computer?

Our body as a whole can be compared with a computer, but it is more correct to draw an analogy between the nervous system and a computer. The brain resembles a computer’s processor. Nerves can be compared to a data bus. Also, our brain has a permanent memory, like the BIOS, where all the vital commands that regulate the processes are “recorded”. We also have an analogue of random access memory, which is processed during the day and goes to the “hard disk” of our brain. That is why the nervous system is compared to a computer.
