C Correct answer
Explanation

This device is a system or an object which can be viewed solely in terms of its input/output and transfer characteristics without any knowledge of its internal workings.

Multiple choice

A system using an automated work cell controlled by electronic signals from a common centralised computer facility is called

  1. adaptive control system

  2. robotics

  3. flexible manufacturing system (FMS)

  4. automatic guided vehicle (AGV) system

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

FMS is defined as a system where automated work cells receive electronic control signals from a central computer. This central coordination enables multiple machines to work together flexibly. Options A, B, and D are incorrect: adaptive control is a feedback mechanism, robotics refers to individual robots, and AGVs are only for material transport.

Multiple choice

Compared to a manual system, the consequences of an error in a computerized system are more serious due to the fact that

(a) errors being generated at high speed will involve higher cost to correct them (b) computer system processes more data (c) users of computer systems perceive the computer output to be always correct

  1. (a) to (c) all

  2. Only (b) and (c)

  3. Only (a) and (b)

  4. Only (a)
