Explanation

An Operating System (OS) is a set of programs that manages computer hardware and software resources and coordinates tasks such as running applications.

It provides essential services like memory management, task scheduling, and file management for smooth computer operation.

Data governance is indeed the practice of:

1. Identifying Important Data: Recognizing which data is critical for the organization's operations and decision-making processes.
2. Ensuring Data Quality: Implementing policies and procedures to maintain high data quality, including accuracy, consistency, and reliability.
3. Improving Data Value: Enhancing the usability and value of data to support business objectives and strategic goals.

Explanation

Magnetic memory (like hard drives and magnetic tapes) is read-write, not read-only — data can be both read and modified.

It is also non-volatile, reliable, and relatively cheap for storing large amounts of data.

Explanation

A low Signal-to-Noise Ratio (SNR) means that noise is stronger than the signal, leading to poor clarity and potential distortion in communication.

A higher SNR indicates a stronger signal relative to noise, resulting in clearer communication.

Explanation

A microphone captures sound waves and converts them into audio signals.

It is the primary device used for voice recording on computers and other digital systems.
