Number Systems
This is the number of digits used in the Hexadecimal Number System.
What is 16?
This is the ASCII character represented by the decimal number 83.
What is S?
This is the number system used to store information digitally in a computer.
What is binary?
This is the process of storing data with fewer bits than the original, and then restoring it to the exact original state when needed.
The original data, a key, and an encryption method.
What is required for any general encryption?
This is the decimal value of 10011.
What is 19?
Non-Jeopardy Format question: What color is represented by this binary sequence?
1111 1111
0000 0000
1111 1111
The color is Magenta (purple, pink, or violet would also be accepted)
This is the highest decimal number that can be represented in one Byte of data (1 Byte = 8 bits).
What is 255?
These are the reasons that we compress data.
What are:
1. Save Storage Space
2. Speed up Transfer Time
3. Trade off storage for computation
This is shifting all letters in a message by a certain key value.
What is a Caesar Cipher?
The number of different values that can be represented using 6 bits.
What is 64?
This is the ASCII value represented by the binary number 01000001.
What is the letter A?
This is the binary value of 19.
What is 10011?
This is the compression method that results in lower quality images than the original image.
What is Lossy Compression?
This is trying every possible combination of an encryption until finding the solution.
What is the brute force method?
This is the error that occurs when we have a value that exceeds the allocated number of bits.
What is an overflow error?
This is the ASCII value of a hexadecimal number 4B.
Non-Jeopardy format question: When we add one more digit (place value) to a binary number, what happens to the number of values that we can use?
We will be able to use twice as many values with the new system.
This is the Run Length Encoding of TEEHEE.
What is T1E2H1E2?
This is the technical term for a problem that as the input gets bigger, the times it takes to solve increases at an exponential rate.
What is a "Hard" computer problem?
This is the values of 2810, 110012, and 1A16 in ascending order.
What is 110012, 1A16, and 2810?
This is a filter that subtracts a set value from each color channel, then takes the maximum of that value and 0 and assigns it back to each channel.
What is a darken filter? (darkness filter or reverse brighten filter also accepted)
Non-Jeopardy Format Question: If we increase the number of bits used to represent a number from 8 bits to 16 bits, how has the number of possible represented values changed?
The new maximum value will be 28 times larger than the previous system (Previous system was 28, and the new system will be 216).
Non-Jeopardy Format Question: What is the Space Savings if we started at 100 bits and ended at 25 bits?
Space Savings = (1 - (size on compressed / size of original) ) * 100
The Space Savings would be 75% smaller
This is the Asymmetric Encryption that sends messages securely. Both parties have 2 keys, but never have to send their secret key to the other.
What is Public Key Encryption?
