Question

A collection of wires that connect several devices in the computer integrated manufacturing system is

• A. Link
• B. Directional wires
• C. Cable
• D. Bus

Hint:

In computer and control systems, a 'bus' is the collective pathway (wires/lines) that allows multiple components or devices to communicate and share data. Think of it as a shared highway for information.

Answer 1

The Correct Option is D

Step 1: Define the terms related to computer connections.
Link: A general term for a connection between two devices or points, but not specifically a collection of wires for multiple devices in a system context.
Directional wires: A descriptive term for wires that transmit signals in a specific direction, but not a standard term for a collection of wires connecting multiple devices.
Cable: A physical assembly of one or more wires, typically insulated and often bundled together, used for transmitting electrical signals or power. While a cable contains wires, it doesn't specifically imply a shared pathway for multiple devices in a system architecture context.
Bus: In computer architecture and distributed systems like those found in Computer Integrated Manufacturing (CIM), a bus is a communication system that transfers data between components inside a computer or between computers. It consists of a set of parallel wires (or lines) that allow multiple devices to share common communication paths. This enables various devices (e.g., sensors, actuators, controllers, computers) in a CIM system to exchange data.
Step 2: Identify the term that best describes a collection of wires connecting several devices in a system.
The term that specifically refers to a collection of wires or lines that serve as a common pathway for connecting multiple devices and transferring data between them in a system is a bus. This is fundamental to how components communicate in CIM environments. The final answer is \( \boxed{\text{4}} \).
