The hard drive of a computer is a device that stores all the software installed on a computer, as well as all the data files created and used by this software. This includes any documents you have created and downloaded, such as photos and music. The hard drive is a form of permanent storage, rather than temporary memory such as random-access memory (RAM).
This means that when you turn off the computer, the files remain safely stored on the drive so you can use them again the next time you start your computer.
How does a hard drive work?
A hard disk drive (HDD) is composed of a platter that contains compartments to hold data. This data is your operating system, applications, and any files you have created. There is also an actuator arm that moves across the platter to read or write the information requested. To make this process faster, the platter spins as the actuator arm moves across it.
The compartments that hold the data can be spread out all over the hard disk. That is, data is not written sequentially. There is an indexing system to allow the actuator arm to find all of the pertinent data.
The platter and the actuator arm are delicate, so they are covered by a steel case. This prevents damage to the disk under normal circumstances.
