• File Management, Task (Process) Management, and Memory Management are responsibilities of the Operating System (OS)
• Memory Management: Allocates and deallocates RAM to programs, ensuring efficient access for the CPU.
• File Management: Handles the storage, organization, naming, and protection of files on storage devices.
• Task/Process Management: Creates, deletes, and schedules processes (tasks) to ensure proper CPU utilization.

Explanation

A compiler is a language translator that converts high-level code into machine code.

It translates the entire program before execution, allowing the program to run independently.

Explanation

Direct current is produced when electrons flow constantly in one direction.

It's abbreviated as "DC".

Since direct current flows in one direction only, its electrical pressure or voltage is always oriented in one direction, or "polarity".

Explanation

Electronics is the branch of science that studies the flow and control of electrons, especially in circuits.

It uses active devices (like transistors and diodes) to control electron flow through amplification and rectification.
