            1. Magnetic Tape
              1. Hard Disk
              2. How do they work?
                1. The main purpose of a storage device to no one's surprise is to store data and memory.
                  1. There are two ways of storing this, one is internally, which are memory devices located inside the system. Examples of this are hard drives and hard disks. The other type of storage is external storage. This includes online storage as well as portable storage devices such as USBs.
                2. Sensors

                                  2. What is a sensor?
                                    1. A sensor allows the computer to register what's going on around it. These sensors can convert real world properties in to data that can e processed
