True or False: A computer virus can hide itself on a floppy disk (diskette) but not on a hard disk drive.

ATrue
-
BFalse
Answer
Correct Answer: False
Explanation
Introduction / Context:This item tests conceptual understanding of what a computer virus is and where it can reside. Early viruses spread via diskettes, but storage medium restrictions are a misconception; viruses are software that can exist on many writable media and within files or boot sectors.
Given Data / Assumptions:
- Claim: Virus can hide in a diskette but not on a hard disk.
- Context: General PC malware behavior, independent of specific OS versions.
Concept / Approach:A virus is malicious code that attaches to hosts (executables, documents with macros, boot records). Its persistence depends on write access and execution, not on whether the medium is a diskette or a hard disk. If code can be written and executed or loaded during boot, a virus can persist there.
Step-by-Step Solution:
Step 1: Identify the nature of a virus → software code that replicates by infecting host files or boot sectors.Step 2: Check media properties → both diskettes and hard disks provide writable storage and boot sectors (MBR/partition boot record) in legacy systems.Step 3: Conclude → if a diskette can harbor a virus, so can a hard disk; the statement is false.Verification / Alternative check:Historical evidence: boot-sector viruses (e.g., Michelangelo era) infected hard disks and diskettes alike by modifying boot records or executable files loaded by the OS.
Why Other Options Are Wrong:
- True: Incorrect because hard disks are just as susceptible as diskettes when malware gains write/execute paths.
Common Pitfalls:
- Confusing infection vectors (e.g., removable media) with limitations on residency.
- Assuming modern protections (e.g., secure boot) apply retroactively to all contexts.
Final Answer:False
