More Terminology
100
This is the university where Shannon received his doctorate.
What is MIT?
100
The world's first computer programmer and protege of Charles Babbage.
Who is Ada Lovelace?
100
The two words that make up this term are the source for the term "bit".
What is binary digit?
100
This is the level of problem that considers how accurately the symbols of communication can be transmitted.
What is "Level A, Technical Problems"?
100
This is what is predictable or conventional in a message.
What is redundancy?
200
This was one of Shannon's hobbies that is typically done with one's hands and several objects, but that he designed a machine to do as well.
What is juggling?
200
According to Fiske, this is "the physical form of a message— sound waves in the air, light waves, electrical impulses, touchings, or whatever."
What is a signal?
200
This is a measure of information.
What is a bit?
200
This is what is being sent.
What is the message?
200
This is a measure of the predictability of the signal, that is the number of choices open to its sender.
What is information?
300
Shannon built this thing as a result of his work on the concept of artificial intelligence. Hint: It was amazing.
What is Theseus, a mechanical mouse that solved mazes in search of a brass cheese?
300
These were the two main "channels of communication" during WWII that Shannon was attempting to make more efficient.
What are telephone cables and radio waves?
300
The two numbers that can be binary digits.
What are 1 and 0?
300
This is what decodes the message from the signal.
What is the receiver?
300
This is the opposite of redundancy. It quantifies the uncertainty involved in predicting the value of a random variable.
What is entropy?
400
These are the years that Shannon was born and died.
What are 1916 and 2001?
400
In the sentence "Roses are red, violets are blue," the word "blue" is highly entropic or highly redundant. Which one is it? [No complaints about the format of the question!]
What is redundant?
400
Shannon developed information theory as a way of finding fundamental limits on signal processing operations and on reliably ________ and ________ data.
What are "storing" and "communicating"?
400
This is the level of problem that considers how precisely the transmitted signals convey the desired meaning.
What is "Level B, Semantic Problems"?
400
This is anything that is added to the signal between its transmission and reception that is not intended by the source.
What is the noise?
500
The condition Shannon became afflicted with in his old age.
What is Alzheimer's Disease?
500
It is a term used to describe deriving pleasure from other people's misfortune. (Hint: German etymology)
What is Schadenfreude? This is random but interesting. It's the idea that we feel better about ourselves by comparison. Consider its implications in the context of social media.
500
If you shuffle a pack of cards and show all the cards singly, each signal will have maximum __________, while if you arrange the cards in order of suits/numbers, each signal will have maximum __________ (provided the receiver understands the pattern of cards).
What are entropy and redundancy?
500
This transmits the message from the sender to the receiver.
What is the channel?
500
These are acts of communication that contain nothing new, no information, but that use existing channels simply to keep them open and usable.
What is the phatic communication?
