The motherboard also holds the ROM, or Read Only Memory, and the RAM, which means Random Access Memory. These will be explained later on. The amount of storage space is usually measured in the computer standard of bytes. Each set of 8 bits is called a byte. One thousand bytes is called a kilobyte, or KB for short.
Storage devices can be either permanent, semi-permanent, or temporary.
Permanent and semi-permanent are pretty much the same thing, the difference being that permanent storage devices cannot be reused once the data is put on them. They are good for archiving permanent records, but unless you are a large company, a historian, or a recording artist, you won't really have much need for permanent storage devices, but I will explain them in a bit. Temporary storage is called memory, and it is a place that the CPU keeps information that it needs to get to alot, but that can be replaced with new information as needed. The most common semi-permanent storage device is the disk drive. Floppy disk drives are almost outdated now, since they required inserting and removing different disks to get the information that you wanted.
