In information systems, a teleprocessing system typically includes which categories of components working together end-to-end?
-
AUser systems
-
BCommunications systems
-
CComputer center systems
-
DAll of the above
-
ENone of the above
Answer
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
