Fun Fact
Computers favor powers of two because binary hardware naturally operates on bits. That is why memory sizes like 8 GB, 16 GB, and 32 GB dominate modern devices.
Historical Context
The concept of powers of two became central with the rise of binary computing in the mid-20th century. Early computer scientists and engineers standardized memory and processing units around powers of two to simplify circuit design and improve computational efficiency - a principle that still governs modern computing architectures.
