Secondary Storage

File Compression

File compression is when the volume or size of a file is decreased or compressed to a smaller volume. Thus, the file occupies a smaller space on your removable storage device. This process is usually done for example, to send a file through the web or online. This makes the sending and receiving process easier as the process is faster the smaller the file is.







Head Crash

A head crash is a serious disk drive malfunction. It is the term given when the 'head' (something that reads the data on the disk) that usually hovers over the disk is misaligned and scratches or even touches the disk. When this happens, a lot of the data and information stored on the disk will be lost.



Internet Hard Drive

It is basically like a storage space but online. Sites engineered for this will allow the user a certain amount or storage space and the user can store pictures, texts and any type of computer file into this storage space on the site. Therefore, the user can be anywhere in the world with an internet connection and will be able to access the files saved on the site.




Optical Disc Drive

An optical disc drive is a driver that stores or retrieves data from an optical disc (CD/DVD). An optical disc is a disc that can store large amounts of information or data.





Solid-state storage

This term means that the storage device does not have movable parts as part of its mechanism. This means that devices like these are more stable and durable than storage devices with movable mechanisms like the external hard drive which can malfunction if it is dropped. Solid-state storage devices would include the infamous USB or pendrive or flash drives or memory cards.
