JRA Tech Chapter 3
Chapter 3 Communication + Mechanical Drawing
| Question | Answer |
|---|---|
| The exchange of information or ideas between two or more living beings. | Communication |
| A Latin root that means "to pass along." | Communo- |
| The transmitting and receiving of information using technical means. | Communication technology |
| One of the most common inputs that controls the sending and receiving of information and data. | Analog voice signal |
| The starting point of a message. | Source |
| This changes your message into another form for transmission. | Encoder |
| This sends your encoded message toward its destination. | Transmitter |
| The wired or wireless means used to send the information. | Medium |
| This accepts the encoded information and relays it to the decoder. | Receiver |
| This translates the encoded message into an understandable form. | Decoder |
| Where the message goes after being sent. | Destination |
| A place for messages in which the messages can be retrieved at a later time. | Storage |
| A response to the receiver's question or statement. | Feedback |
| An action in which you take out stored information in your mind and remember it. | Retrieval |
| Six basic reasons for communicating. | To inform, persuade, educate, entertain, control, or manage |
| One thing that informs when communicating. | Local news broadcast |
| Two things that persuade when communicating. | Salesperson and TV commercial |
| Two things that educate when communicating. | Teacher and professor |
| Three things that entertain when communicating. | Popular comedian, musician, and movie star |
| One thing that controls when communicating. | Electrical engineer |
| One thing that manages when communicating. | Supervisor |
| This presents ideas in a form we can see. | Visual communication |
| Messages that can be heard. | Audio communication |
| This communication is both seen and heard. | Audiovisual communication |
| Lines and shapes that represent objects and ideas. | Line drawings |
| Drawings of the ideas to be communicated. | Drafting |
| Drafting has always been known as this. | "The Language of Industry" |
| The simplest type of drawing and one of the quickest ways to share an idea. | Sketching |
| This is a 3-D version of sketching and is less realistic than perspective sketching. | Isometric sketching |
| Paper that has a grid of vertical lines. | Isometric paper |
| This provides the most realistic picture of objects. | Perspective sketching |
| This kind of drawing shows each surface of the object "square on," that is, at right angles to the surface. | Orthographic projection |
| The view that shows the front of an object. | Front view |
| The view that shows the top of an object. | Top view |
| The view that shows the right side of an object. | Right-side view |
| Three tools used to sketch orthographic views easily. | Drafting triangles, compass, ruler |
| A thin, faint line used to start a drawing. | Construction line |
| A dark, thick line used to show the outline of an object. | Object (visible) line |
| A line of short and evenly-spaced dashes used to show hidden features. | Hidden line |
| A line of alternating long and short dashes used to show the centers of holes. | Centerline |
| A thin line used to show the size of an object and its parts. | Extension + dimension line |
| The lines that show the outline of an object. | Object lines |
| A drawing that is larger or smaller than the object by a fixed ratio. | Scale drawing |
| A scale that is larger than the object by a fixed ratio. | Enlarged scale |
| A new form of drawing that stands for Computer-Aided Design. | CAD |
| Three devices or parts a typical CAD system has. | Input device, processor, output device |
| Two common input devices on a CAD system. | Keyboard + digitizer |
| A virtual reality projection screen that is used in the most advanced CAD systems. | Power wall |
| An artificial environment provided by a computer that creates sights, sounds, and, occasionally, feelings through the use of a mask, speakers, and gloves or other sensory-enhancing devices. | Virtual reality |
