Question 1

A network that connects low-level devices directly to plant-floor controllers without interfacing them through I/O modules is an example of a(n) ____.&#10;A) EtherNet/IP network&#10;B) ControlNet network&#10;C) Data Path network&#10;D) DeviceNet network

Accepted Answer

Directly connecting low-level devices to plant-floor controllers without the use of I/O modules is the main purpose of DeviceNet network. EtherNet/IP, ControlNet, and Data Path networks may use I/O modules as an interface between devices and controllers.

Question 2

A benefit of ____________________ architecture is that data communication equipment can be purchased from several different manufacturers.

Accepted Answer

open &#10;open system

Question 3

Fiber-optic cable is not affected by electromagnetic interference.

Accepted Answer

Fiber-optic cable uses light signals to transmit data, so it is not affected by electromagnetic interference.

Question 4

____________________ data transmission allows for the source data to start and stop when ready.

Accepted Answer

The answer of ____________________ data transmission allows for the source...

Question 5

The ____________________ is a complex set of computer-controlled processes.

Accepted Answer

The answer of The ____________________ is a complex set of...

Question 6

The process of determining the way in which the string of digital data fits together, how the communication is started and ended, whose turn it is to send or receive data, and how messages are confirmed is controlled by a(n) ____.

A) protocol
B) application layer
C) PLC
D) control device

Accepted Answer

The process described in the question is controlled by a protocol, which is a set of rules and standards that govern the communication between devices in a network. The application layer is a higher-level layer that deals with specific applications and services, but it does not control the communication process. PLCs and control devices are hardware components that may be used in a network, but they do not control the communication process either.

Question 7

____ is defined as the transmission of data converted into a digital coded format (1s and 0s) to and from one place to another over an interconnected system.&#10;A) Data highway&#10;B) Information technology (IT)&#10;C) Business data processing&#10;D) Data communications

Accepted Answer

Data communications specifically refers to the transmission of digital data over interconnected systems. The other options may be related to data transmission but do not specifically refer to digital coded format or interconnected systems.

Question 8

Serial transmission allows for every bit of the data to have its own wire in a cable.

Accepted Answer

Serial transmission sends data sequentially over one single wire or channel. It does not use a separate wire for each bit of data.

Question 9

____ data transmission is the movement of data that is controlled by a clocking device that determines exactly when data should move.&#10;A) Parallel&#10;B) Serial&#10;C) Synchronous&#10;D) Asynchronous

Accepted Answer

Synchronous data transmission relies on a clocking device that synchronizes the timing of the sending and receiving devices, ensuring that data is moved at a consistent and predictable rate. Parallel transmission moves multiple bits of data at once, while serial transmission moves one bit at a time. Asynchronous transmission does not have a clocking device and relies on start and stop bits to indicate the beginning and end of a data packet.

Question 10

The concept of layering of information breaks down the complex process of transporting data into pieces that can be managed by single network devices.

Accepted Answer

The concept of layering of information allows for the organization of data into different layers that can be managed by individual network devices. This simplifies the overall process of transporting data and makes it more efficient.
