Frequently Asked Questions

What is the difference between powers of two and powers of ten?

Powers of two are 2^n (1, 2, 4, 8, 16, ...) while powers of ten are 10^n (1, 10, 100, 1000, ...). Powers of two are fundamental in computer science and binary systems, while powers of ten are used in decimal systems and scientific notation.

Why are powers of two important in computer science?

Powers of two are fundamental in computer science because computers use binary (base-2) number systems. Memory addressing, data structures, algorithms, and digital systems all rely on powers of two for efficiency and simplicity.

How do I convert a power of two to binary?

Powers of two have a special binary representation - they have exactly one 1 bit followed by zeros. For example, 2^3 = 8 = 1000₂, 2^5 = 32 = 100000₂. The position of the 1 bit corresponds to the exponent.
