Speakers can also be an example of this as the song comes from the computer out into the open.

Data Storage

There are 3 ways memory is stored onto a computer, Through Optical storage, Magnetic and through Solid State.

Optical storage is made and read by laser and light, an example of optical storage is a DVD as it is read by light in the DVD Player.

Magnetic Storage is data on magnetized strips of metal, an example of this is a sim card, it has the metal where it goes in the phone in order for the data to be read.

Solid State Drive, or SSD is a memory drive that uses USB in order to be read, this includes input and output for data to be moved. A hard drive is an example of SSD, it has a memory circuit on the inside of the block and connects to the computer through USB.
