A computer's power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. You are building a new computer. You are deciding which type of power supply to install.

The definition which best describes the given statement is given below:

Explanation:

Dual rail electricity supply includes independent tracks, P C B traces that are used to offset the voltage sags between different circuits, avoiding overloading of any circuit. Practically all inverters use semiconductors to deliver a controlled power output. If the source does have an ac input, then an input voltage is rectified.

Therefore, it's the right answer.
