Function and structure of CPU

Function and structure of CPU

1. CASE: Specialised to support and protect the disk that is with in the case.

2. PLATTERS: Flat circular disks which record the data. Made from non magnetic material which is why it is a magnetic type of storage.

3. READ & WRITE HEADS: Positioned near the magnetic surface so they can easily read and write on it, modify the surface as they pass over it.

4. ACTUATOR: Magnet and motor which move the head to its location.

5. DATA: The data is stored with magnetism and binary on the platters divided into billions of areas. Either magnetized to a 1 or a 0.

6. SPINDLE: Its a flat circular disk that spins the platters.

   • CONTROLLER: Its allows the CPU to communicate with a hard disk
