AP Computer Science Principles Unit 1 - Binary Data

What is an overflow error

• An error that occurs when a program runs out of memory.

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

• An error that happens when a file is too large to be saved.

• An error that occurs when the computer's processor overheats.

What is the difference between a bit and a byte?

• A bit is the smallest unit of digital information.

• A byte is made up of 16 bits.

• A bit is made up of 8 bytes.

• A byte is the smallest unit of digital information.

What is difference between digital and analog?

• Analog Signals are continuous while Digital Signals are discrete

• Digital Signals are continuous while Analog Signals are discrete

• Both Analog and Digital Signals are continuous

• Analog Signals are faster than Digital Signals

What is sampling?

• Method of converting analog signal into digital signal

• Process of selecting a subset of individuals from a population

• Technique for measuring the frequency of a signal

• Approach to analyzing data trends over time

If the ASCII value of A is 65, then what is DFG encoded to?

• 68 70 71

• 65 66 67

• 70 71 72

• 66 67 68

How does copyright work?

• Copyright is a legal protection that automatically grants exclusive rights to the creator of an original work of authorship, allowing them to control how the work is reproduced, distributed, and displayed.

• Copyright is a system that allows anyone to use any work without permission after a certain period.

• Copyright is a type of insurance for creators to protect their work from being stolen.

• Copyright is a legal requirement for all published works to be registered with the government.

What is a bit?

• Smallest unit of digital information

• A type of computer virus

• A unit of measurement for data storage

• A programming language

What is intellectual property?

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

• A type of physical property that can be owned

• A term used to describe real estate and land ownership

• A legal term for financial assets and investments

How is a bit represented on a computing device?

• A bit is represented by 0 or 1 to represent ON (1) and OFF (0)

• A bit is represented by a single character in ASCII

• A bit is represented by a byte of data

• A bit is represented by a hexadecimal value

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

• 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

• Step 1: Divide the decimal number by 2, Step 2: Write down the remainder, Step 3: Repeat until the number is 0

• Step 1: Subtract the largest power of 2, Step 2: Write a one for that power, Step 3: Repeat for the remainder

• Step 1: Convert the decimal to hexadecimal, Step 2: Convert hexadecimal to binary, Step 3: Combine the binary numbers
