I've heard that a standalone computer is more secure because it's not connected to any network that could potentially allow a hacker inside. Actually, that's not true, every computer is always connected to another computer via a network. It's an older form of network and is just as susceptible to hacking as any other network. This network uses chemical signals to operate and has it's own processor built in. It also uses a variety of different physical processes to communicate with other computers of its own kind and other kinds. The physical processes include sound, light, pressure, odor and flavor as a medium to transmit some of its information. It can also use geometric shapes and figures to encrypt some of the information for easy transport. It has its own memory just like all computers do and can store the information fairly efficiently by means of certain chemical processes. By now you should have pretty much guessed what network it is... the human network. No computer system in the world is ever truly standalone when it's connected to the human network.
