Among these there are certain electronic components which come of use at home as well as in your professional life. Let us discuss in brief three of such components, namely, Passive and Active components and Portable External Hard Drive.

Active and Passive Components: Active components are electronic components which need some source of power to function. Some common examples of active components are transistors, bipolar and field effect ones and integrated circuits. These active components are used to augment signal power whereby the signal is sent through one end of the device and the amplified version sourced from another connection. A DC Voltage from a battery constitutes the power source in general. Components which do not need any power or energy source to operate in a field of application are Passive ones. Here, the energy is preserved in the form of voltage or current. Capacitors, resistors, diodes and inductors are some examples in this case.

Portable External Hard Drive: Portable external hard drives or simply portable hard drives are one of the most coveted computing accessories these days because of the additional storage capacity it proffers you with. They act as great back-up devices for your computer while being light in weight and convenient enough to carry everywhere you go.
