Binary vs Decimal Systems
Binary (1024-based): Used by operating systems
1 KiB = 1,024 bytes
1 MiB = 1,024 KiB = 1,048,576 bytes
1 GiB = 1,024 MiB = 1,073,741,824 bytes
Decimal (1000-based): Used by storage manufacturers
1 KB = 1,000 bytes
1 MB = 1,000 KB = 1,000,000 bytes
1 GB = 1,000 MB = 1,000,000,000 bytes

Important Notes
• 1 byte = 8 bits (fundamental relationship)
• Storage manufacturers use decimal, OS shows binary (explains "missing" space)
• Network speeds typically measured in bits per second (bps)
• File compression can significantly reduce storage requirements
