What involves having a system imitate another system?

• A. Metadata
• B. Tag
• C. Blob Storage
• D. Emulation

Answer: (D)

Emulation is the process of making one system imitate the behavior of another, so software or devices designed for the original system can operate on a different platform. This involves replicating the other system’s interfaces, instructions, timing, and responses closely enough for the target system to run the software or for the behavior to be studied. For example, a game console emulator lets a PC run games created for that console by translating its hardware calls into the PC’s hardware actions. In security contexts, emulation can be used to analyze malware or to simulate a target environment without the actual hardware. The other terms describe different ideas: metadata is information about data, a tag is a label, and blob storage is a storage service for large binary objects. None of these involve reproducing another system’s behavior.
