Commonly, external hard drives will acquire power from the computer it is connected to. It is possible, though, to connect external hard drives to an outlet and permanently to the computer, replacing the previous hard drive, though I highly do not recommend such.
External. An internal hard drive would be any hard drive built into a computer, that cannot be easily removed and transported to another computer. External hard drives can be easily moved and in the case of flash drives, can be used for temporary data storage and transfer.

External hardware is hardware that is connected externally to a computer using its peripheral ports. Examples are VDU, keyboards and mice.
External Hard Drives are generally connected to USB ports or FireWire ports.
Holding down the Option key while starting up a computer running Mac OS X will enter the Startup Manager from which the source for the computer to boot from can be selected. Ensure that external drives are powered and connected before turning on the computer. Intel based Macs can be booted from USB2 or FireWire drives while older Macs will not boot from USB drives.
When they work together, they create what is known as a computer. Hardware is just external drives, like flashdrives and external hard drives. Software is what is in the computer, like the motherboard. Together, they make a computer.

The peripherals are all of the input/output devices that are connected to the computer, including the keyboard, mouse, monitor, printer, external drives, scanner, router, etc.
The best secondary storage device that I have found is a Desktop External Drive. They are USB run and can easily be connected to the computer or disconnected. Pen or Thumb Drives do not have a large amount of space, like External Drives have, and Thumbs can be easily lost.
Yes, you can install multiple hard drives in your computer. If you have multiple internal bays then you can install drives inside the case. If not, you can buy external Firewire and USB drives that attach to the ports on the back of your computer. If you are unfamiliar with opening your computer, then choosing an external solution is the easiest and beth method.
Internal components are devices that are either built-in to the motherboard of the computer, added on an expansion card or a device attached to the motherboard by way of ribbon cables. External devices are added to the computer system by plugging them into one of the ports on the back of the computer.
