Answer:
CPU, RAM, and Storage
Step-by-step explanation:
The three hardware components that are inside every computer and are essential for it to function are CPU, RAM, and Storage (HDD, SSD). CPU is basically the brain of the computer where everything is calculated. The RAM is the memory that stores temporary information. Lastly, the Storage device is where the entire operating system and persistent data will be saved and accessed from. 64-bit processors are better simply because they can access more memory at any given time and therefore allows it to manipulate more data at the same time.
