Daily Binary and Data Representation tests for kids
Binary numbers, how computers store text and images, and units of data. Age-appropriate daily practice for ages 9–13.
Sample questions
Here's a taste of what your child will practice. New questions every day on Dailulu.
To represent numbers using only 0s and 1s, we use the ____ numbering system.
The binary numbering system is essential for how computers operate, as it is based solely on the digits 0 and 1.
What is the binary representation of the decimal number 8?
The decimal number 8 equals 1000 in binary (1×8 + 0×4 + 0×2 + 0×1 = 8). This represents a power of 2, which is why it has a single 1 followed by zeros.
How many bytes are there in 64 bits?
Since there are 8 bits in a byte, 64 bits divided by 8 bits per byte equals 8 bytes.
Data can be represented in forms other than binary, such as decimal or hexadecimal.
While binary is the primary system for computers, data can also be represented in decimal and hexadecimal formats.
