Hard Drive (HDD)/SSD
A Hard Disk Drive is a component that stores all the information on a computer, such as documents, applications, pictures and games. It has a disk and an arm, the arm writes the information into the disk and enables it to be accessed later.
A Solid State Drive does the same job, but is much smaller, faster and has no moving parts. It is used in tablets and smartphones, while a HDD is still mostly used in laptops and computers.
