Part A: Protecting Computer Storage Media
We must give particular attention to protecting computer storage media, because they are the primary
means of storing computer programs and the information processed by computers, and they are the
components of a computer which are perhaps the most vulnerable to loss and damage. This lesson
will introduce you to computer storage media and procedures for protecting this storage media from
harm.
Part B: Computer Storage Media Defined
First, what is "computer storage media?" "Media" is the plural of "medium" and includes "any
substance or material on which information is represented or stored, and is used for input or output."
There are two general categories of computer storage media:
Magnetic Storage Media: Floppy disks and hard disks are magnetic storage media; information is
stored as tiny, invisible magnetic forces on the iron-oxide material which coats the surface of the
disk.
