Bits to Represent Data
What process reduces the size(number of bits) of transmitted or stored data?
Data Compression
Do more privacy concerns arise with more data?
Yes
What can be used to represent images, color, boolean logic, and lists in computing?
A Binary Sequence
1100 0111₂ → hexadecimal
C7₁₆
Which type of error occurs when you add the numbers 5 and 11 in a 4 bit binary system?
An Overflow Error
Which type of data compression can significantly reduce the file size while decreasing resolution and losing some data?
Lossy Data Compression
What is it called when somebody impersonates somebody else on the internet by using their personal data?
Identity Theft
What can be used to generalize and shrink the code?
An Abstraction
Which type of error may occur if you multiply 1/3 by 6?
A Roundoff Error
Which type of data compression allows no data to be lost, but results in larger files?
Lossless Data Compression
What is data that describes your data?
Metadata
What is data that cannot be represented by a binary sequence?
Analog Data
A3₁₆ → decimal
163₁₀
Which type of data compression would be most appropriate when it is ok for minor data to be lost and it is more important to reduce the size of the file?
Lossy Data Compression
In a file that contains an image, would a description of the image be regular data or metadata?
ex: A dog is playing in the snow
Regular Data
Sort the following numbers from least to greatest:
1011 1010₂
192₁₀
B9₁₆
B9₁₆, 1011 1010₂, 192₁₀
What is 1110001₂ + 67₁₀ + 1A₁₆ in hexadecimal?
CE₁₆
Which type of error could be fixed by expanding the binary range of a system?
An Overflow Error
Which type of data compression would be most appropriate when it is not ok for any data to be lost and it is more important to be able to retrieve the original file?
Lossless Data Compression
Would the data describing the file be regular data or metadata?
ex: the pictures filename, location where the picture was taken, the date the picture was taken, and the author of the picture
Metadata
