In information systems, a teleprocessing system typically includes which categories of components working together end-to-end?

Difficulty: Easy

Correct Answer: All of the above

Explanation:


Introduction / Context:
Teleprocessing refers to processing that involves terminals or user systems communicating with a central or distributed computer through communication facilities. Modern client-server and mainframe-terminal architectures are examples.


Given Data / Assumptions:

  • Teleprocessing spans end-user interaction, transmission, and centralized computing resources.
  • We are looking for the complete set of categories involved.


Concept / Approach:
Any teleprocessing arrangement must include endpoints (user systems), a transmission path or network (communications systems), and computing resources (computer center systems). Removing any one of these breaks the end-to-end design.


Step-by-Step Solution:

1) Identify the endpoint: user systems such as terminals, PCs, or thin clients. 2) Identify the transport: communication lines, modems, switches, and protocols. 3) Identify the processing hub: computer center systems such as mainframes, servers, databases, and applications. 4) Conclude that all three categories are integral.


Verification / Alternative check:
Classic mainframe CICS or modern web apps both fit this triad: users, network, servers. If any is missing, teleprocessing cannot occur.


Why Other Options Are Wrong:

  • User systems alone do not enable remote processing.
  • Communications systems alone cannot process or originate business logic.
  • Computer center systems alone cannot be reached by users without a communication path.
  • None of the above fails because all are indeed required.


Common Pitfalls:
Confusing teleprocessing with batch-only systems; assuming peer-to-peer negates the need for a central system (it still requires user endpoints and communications); overlooking that modern cloud still embodies the same triad.


Final Answer:
All of the above
