Question

Options

• ALack of connectivity with other systems and controlled access
• BAbility to operate on an open internet platform without security
• CUse exclusively in social networking contexts
• DInability to process data efficiently

• A
  85% (35)
• B
  2% (1)
• C
  7% (3)
• D
  5% (2)

Explanation

Option A is correct because closed computerized systems are characterized precisely by their isolation from external networks and restricted access controls - they operate in a contained environment where only authorized users or processes can interact with the system.

Why the distractors fail:

• B describes the opposite - open internet platforms without security represent open systems, not closed ones.
• C is a nonsensical distractor; system classification (open vs. closed) has no relationship to social networking use cases.
• D confuses access architecture with processing capability - closed systems can be highly efficient at data processing; "closed" refers to connectivity and access, not performance.

Memory tip: Think of a closed system like a locked filing cabinet - it's not connected to the outside world and only approved people have the key. "Closed" = controlled boundaries, not broken functionality.
