What is the difference between a bit and a byte?
There is no difference.
One is computer, another is when you eat.
A bit is one place value either a 0 or a 1, and a byte is 8 bits.
8 bytes equals a bit.
How is a bit represented on a computing device?
As a 0 or a 1. 0 is off. 1 is on.
As an image you create.
Depends on how many letters are used.
As a single byte.
Do you understand how computers represent complex information?
They represent them as binary, a complex base-2 numbering system using 0's and 1's.
They represent them in images, which are pulled apart and put back together.
Computers do not represent any complex information.
Multi-level base-10 using ASCII.
What are the similarities and differences in how binary, ASCII, and RGB is represented?
ASCII uses binary to represent text characters, while RGB uses binary to represent colors through combinations of red, green, and blue values.
ASCII and RGB are both based on base-10 representation.
ASCII represents colors, while RGB represents text characters using binary.
Both ASCII and RGB use binary to represent numerical values only.
What is the difference between digital and analog?
Digital representation uses discrete values, while analog representation uses continuous signals.
Digital representation can only represent audio, while analog can represent video.
Analog representation is more accurate than digital representation.
Digital representation is slower than analog representation.
What are overflow errors? What are round-off errors?
Overflow errors happen when calculations exceed data type limits -or memory allowed-, while round-off errors occur when numbers are approximated.
Overflow errors are caused by incorrect data types, while round-off errors are due to data loss.
Overflow errors occur during data transmission, while round-off errors happen during data storage.
Overflow errors are related to memory allocation, while round-off errors are related to network latency.
What is an example of a base-2 numbering system?
Decimals.
Fractions.
Binary.
Whole numbers.
What is an example of base-10 numbering system?
0000000010.
0123456789.
1111111111.
0000000000.
Describe the main characteristic that differentiates lossy compression from lossless compression.
Lossless is better.
Lossy is better.
They both have their uses. Lossy however removes data permanently while Lossless will retain the original data.
Lossy compression is a unique algorithm used for pictures and texts while Lossless crunches video and audio only.
What is intellectual property?
Special laws protecting copyrights, patents, and trademarks.
Prohibits the downloads of software, games, music, and movies that are created and/or owned by others.
Protects ideas, concepts, and symbolic creations.
All the above.
What does Creative Commons do for people?
Eliminates copyrights.
To enforce copyright.
Promote commercial use of creative works.
Provide a flexible range of freedoms and protections for authors, artists, and educators to share their works creatively.
