A classic batch processing terminal is designed for offline job submission/output. Which component would such a terminal typically NOT include?

Introduction / Context:Batch processing historically separated job preparation from job execution. Terminals in this context served as peripheral stations to submit decks (cards) and collect printed output while the central mainframe performed computation.

Given Data / Assumptions:

• Terminals are not general-purpose computers.
• They provide I/O devices to feed and retrieve batch jobs.

Concept / Approach:A batch terminal usually includes input devices (card reader/punch) and output (line printer) but lacks an independent CPU capable of executing arbitrary programs. Computation occurs at the host; the terminal is essentially a remote I/O station.

Step-by-Step Solution:

Verification / Alternative check:Historic system diagrams show Remote Job Entry (RJE) stations with readers/printers connected to the host; logic in the station is minimal, focused on device control rather than compute.

Why Other Options Are Wrong:

• Card reader/punch: essential for job submission in card-based workflows.
• Line printer: essential for receiving printed output.
• None: incorrect because the CPU is indeed not present.

Common Pitfalls:Confusing an intelligent workstation with a batch terminal; assuming every “terminal” contains a CPU comparable to a computer—batch terminals were peripheral I/O stations.

Final Answer:CPU
