HARD DISK

HARD DISK :

A hard disk drive (HDD), of ten referred to as a hard drive or hard disk,is a data storage device used in computers. It uses magnetic storage to store data, which can be accessed rapidly due to the mechanical components that spin the platters and move the read / write heads.

Data storage :

Hard drives are the primary way computers store information,including operating systems,applications,and user files.

Magnetic storage :

They use spinning platters with a magnetic coating where data is stored as magnetic patterns.

Read/Write Heads :

These heads move over the platters to read and write data.

Non-Volatile :

Unlike RAM,HDDs retain stored data even when the computer is powered off.

Capacity :

 Hard drives capacity is typically measured in gigabytes (GB) or terabytes (TB).

Components :

HDDs consist of platters,a spindle motor,read/write heads,and integrated electronics.

Access Speeds : 

While HDDs are reliable and offer large storage capacity,SSDs are generally faster due to their solid-state design, using flash memory instead of mechanical components.
