Concerning communications, please describe digital technology versus analog technology. Please also provide the graph of each technology on the white board.
ANALOG TECHNOLOGY (old school) is when the message is recorded in its original form. DIGITAL TECHNOLOGY is when the original wave is sampled and then converted to BINARY CODE

List the benefits that would result if you replaced human workers with robotics in a manufacturing system
More uniform production. Decreased production costs. Robotics work 24 hrs/day. Robotics are cheaper to operate than humans

What two things can be done to a fluid system, in order to increase the velocity in the fluid?
To increase velocity you can REDUCE THE DIA. or REDUCE BENDS IN A SYSTEM (straighten pipe out)

What is the purpose of a variable resistor? What does it do?
A variable resistor may change its resistance, therefore the current may change. Dimmer switches are good examples

List the benefits of digital technology over analog technology
More compact/smaller. More portable. Easier to edit and manipulate. Doesn't degrade as easily as analog. Faster than analog
200
List the cons that would result if you replaced human workers with robotics in a manufacturing system
Can't custom make things. If present, errors will be repeated over and over. High startup costs. Cant problem solve issues

When you 'feel' a fire on your face, how is the thermal energy reaching you?
Radiation
200
If voltage is kept the same, what happens to current when you double (x2) the resistance
If the resistance is doubled, the current will be cut in half

Concerning fiber optics, what function does the CLADDING serve? What function does the CORE serve?
The CLADDING keeps everything totally internally reflected. The CORE carries the modulated light signal.

DC voltage sources have a positive terminal and a negative terminal. Why do AC voltage sources not have positive and negative terminals?
In an AC supply, voltage at each terminal is always changing
