Final answer:
All digital devices require a power source and a method of storing and processing digital information.
Step-by-step explanation:
In order to work, all digital devices need two things: a power source and a method of storing and processing digital information.
A power source, such as a battery or a power cord, is required to provide the electrical energy necessary to run the device. For example, digital cameras require batteries to function, with most using rechargeable batteries. Some devices, like computers or cell phones, can be powered through a power cord plugged into an electrical outlet.
Additionally, all digital devices require a way to store and process digital information. This can be in the form of memory cards, built-in memory, or hard drives. The device also needs a processor to process and execute instructions, perform calculations, and handle data. For example, a computer uses a hard drive to store data and a central processing unit (CPU) to perform tasks.
