Comprehensive and Detailed In-Depth Explanation:

Computer hardware refers to the physical components of a computer system.

Workstation: A high-performance computer designed for technical or scientific applications.

Modem: A device that modulates and demodulates signals for data transmission over communication lines.

Disk drive: A device that reads and/or writes data to a disk storage medium.

Option D lists only physical components, fitting the definition of computer hardware.

In contrast:

Value-added network (option A): A hosted service offering specialized networking services, not a physical component.

Data warehouse (option B): A system used for reporting and data analysis, representing a data storage concept rather than a physical device.

Firewall (option C): While it can be hardware, it is often implemented as software; thus, the term doesn't exclusively denote hardware.

Therefore, option D accurately represents a list of computer hardware components.

Comprehensive and Detailed In-Depth Explanation:

Physical and environmental IT controls focus on securing IT infrastructure against unauthorized access and environmental hazards. Locating servers in locked rooms with restricted admission protects hardware from theft, tampering, and environmental risks.

Option B (Applying encryption) – A logical security control, not a physical one.

Option C (Access rights allocation) – A logical control related to identity management.

Option D (Software patch control) – Part of IT governance and system maintenance, not physical security.

Since physical access control is a critical component of IT security, Option A is correct.
