AP Computer Science Principles Unit 1 - Binary Data

Front

What is a bit?

Back

Smallest unit of digital information

Front

What is the difference between a bit and a byte?

Back

Bit - smallest unit of digital information

Byte - made up of 8 bits

Front

How is a bit represented on a computing device?

Back

Front

What is difference between digital and analog?

Back

Analog Signals are continuous while Digital Signals are discrete

Front

What is sampling?

Back

Method of converting analog signal into digital signal

Front

How do you represent binary into decimal numbers

Back

Step 1: Write out the 8 places

Step 2: Fill out the numbers that are given

Step 3: Write the place number (i.e 2^0, 2^1) under the line

Step 4: Multiply the numbers

Step 5: Add the results together to get the decimal number

Front

What is an overflow error

Back

An error the computer receives when the number is too large to be represented with the number of bits

Front

What is a round-off error?

Back

An error the computer gets when the number is too precise to be represented by the number of bits

Front

How do you convert the decimal number into a binary number?

Back

Step 1: Write the placements

Step 2: See which numbers will add up to the decimal number

Step 3: Write a one on those numbers and the 0 on the rest

Remember: If there is 0s before the 1, no need to write the 0s

Front

What is intellectual property?

Back

A legal term for the creation of the mind, such as inventions, artistic works, and designs
