Storage Devices and their Categories

There are several different types of Storage Devices. The purpose of Storage Devices is to save information, display it, or erase it. Storage Devices can be classified as Portable Memory. Short Term Memory, and long term memory. One example of a storage device is a RAM (Random Access Memory). This type of memory involves data being stored in a computer, but when a computer is turned off, the memory is erased. This example of Short Term Memory. An External - Hard Drive is an example of Portable Memory. You save data in it, and then you can plug into any computer to access your data. A Floppy Disk is an older example of memory and it is also portable. However, its storage capacity is very low, and is very fragile. 

A hard drive is an example of Long Term memory, because it is incorporated in a computer, and cannot be taken out. A flash drive and a memory card are also examples of more portable data which can be taken and accessed anywhere. A CD-ROM is an example of Potable Memory which can be read by a computer, but it's contents cannot be changed. In order to change the contents of a CD-ROM the CD has to be CD-RW meaning Compact Disc-Rewritable. Another portable storage device is a DVD which stores information in a media format. The final example of a storage device is an online storage service such as Mediafire, which make digital copies of data and stores them on the web. This is an example of both Portable and Long Term Storage because it can be accessed from anywhere, and this information will be saved for as long as you want.
