Question 1

Explain computer graphics.

Accepted Answer

Computer graphics broadly identifies drawings, three-dimensional displays, color animation, and other visual products drawn with the aid of a computer.

Question 2

The direction and line representing the horizontal plane in the Cartesian coordinate system form the ____ axis.

Accepted Answer

The horizontal plane in the Cartesian coordinate system is represented by the X-axis, which typically runs left to right.

Question 3

____ links CADD/CAM, electronics, fluidics, and robotics to create automated factories.

Accepted Answer

Computer-Integrated Manufacturing (CIM) links CADD/CAM, electronics, fluidics, and robotics to create automated factories.

Question 4

The CADD computer includes a number of ____ chips, each of which controls a specific function.

Accepted Answer

The term "chip" typically refers to an integrated circuit, which contains multiple components such as transistors, diodes, and resistors on a small piece of semiconductor material. In a CADD computer, each chip would likely be responsible for a specific function such as processing graphics, controlling input devices, or managing memory. Vacuum tubes (A) and relays (C) were used in early computers, but integrated circuits are much more common in modern systems. An interface (D) can refer to a physical connector or a piece of software that enables communication between different components, but it is not specifically related to the chips in a CADD computer.

Question 5

Information in a CADD system that is on the display screen is known as ____.

Accepted Answer

Information on the display screen in a CADD system is known as softcopy, as opposed to hardcopy which refers to a physical printout of the information. The information on the screen is temporary and serves as a reference for the user.

Question 6

Explain what a Computer-Aided Manufacturing system is.

Accepted Answer

The answer of Explain what a Computer-Aided Manufacturing system is....

Question 7

Describe the model displayed in the accompanying figure and explain the subsystems that might be involved in the model.

Accepted Answer

The answer of  Describe the model displayed in the...

Question 8

The rectangular coordinate grid of the ____ coordinate system provides the foundation on which drawings produced by CAD are generated.

Accepted Answer

The Cartesian coordinate system, named after mathematician René Descartes, uses a rectangular grid to represent points in a two-dimensional space. This is the most common coordinate system used in CAD software to create and manipulate drawings.

Question 9

Discuss the capabilities of CAD systems.

Accepted Answer

The answer of Discuss the capabilities of CAD systems....

Question 10

List the three major components of a robot.

Accepted Answer

The answer of List the three major components of a...

Question 11

A ____ is used for entering much of the drawing details, such as lines, symbols, circles, and objects.

Accepted Answer

A digitizer is a device used to convert analog information into a digital format, often used for detailed drawing and design work.
