Bits and Bobs
Binary data uses these 2 digits.
What are 1s and 0s?
In math we usually represent numbers in this 10 digit system.
What is decimal?
Any number that can be written without a fractional component.
What is an integer?
Mappings from a character to a binary number are called this.
What are encodings?
A continuous stream of varying data.
What is analog?
One of these stores a single 1 or 0.
What is a bit (binary digit)?
Computers use this number system to represent information with just 1's and 0's.
What is binary?
The largest number value that 3 bits can represent.
What is 7?
One of the first standardized encodings that is still commonly used today.
What is ASCII?
The inverse of a sampling interval.
What is a sampling rate?
A single bit can only represent this many values.
What is 2?
In decimal, digits are multiplied by this power.
What is 10.
This kind of error happens when a number is too large.
What is an overflow error?
Each English letter in ASCII is encoded in binary using this many bits.
What is 7?
According to this theorem, a sufficient sampling rate is anything larger than twice the highest frequency in the signal.
What is the Nyquist-Shannon sampling therom?
A sequence of 2 bits can represent this many values.
What is 4?
In binary, digits are multiplied by this power.
What is 2?
Most modern computers use architecture that runs on this many bits.
What is 64?
"A" represented in ASCII.
What is 1000001?
The unit frequency is usually measured in.
What are hertz.
A sequence of 3 bits can represent this many values.
What is 8?
The decimal number 10 is represented in binary by this number.
What is 1010?
Computer languages typically use this kind of representation for non-integers.
What is floating-point representation?
"B" represented in ASCII.
What is 1000010?
The highest frequency that humans can typically hear.
What is 20kHz?
