If firmware is not updated properly than any software or application will not work properly. Updating Firmware is also a risky job because if we are doing it in any laptop then we will need to continuously put it on charge the whole time & also the accurate model number and system firmware should be installed otherwise there are chances of damaging the whole motherboard.

(Ques-3) What are SSD & HDD ?
(Ans-3)
- SSD is an PC storage device that uses Solid State memory to store information.
- SSD uses non volatile NAND Flash Memory, which enables it to retain data when the power is removed.
- It is a data storage device in a computer.
- It is a secondary storage device.
- Its stored in 0 (or) 1.
- The OS, software and most other files are stored in the HDD.
