1073741824

1073741824 is a decimal integer equal to 2^30. In hexadecimal it is 0x40000000, and in binary it is a 1 followed by 30 zeros. This value is commonly encountered in computing as the exact number of bytes in one gibibyte (GiB), since one GiB equals 2^30 bytes, or 1,073,741,824 bytes. Consequently, 1073741824 bytes is often used as a canonical size for memory and storage capacities in binary-prefixed contexts.

In the distinction between binary and decimal prefixes, 1073741824 bytes is precisely one gibibyte, whereas in decimal terms the equivalent size is about 1.0737 billion bytes, sometimes referred to as 1.073 gigabytes for convenience, though that usage can be misleading in strict contexts. The term gibibyte (GiB) is the correct binary unit for 2^30 bytes, while gigabyte (GB) typically denotes 10^9 bytes in decimal measurements.

Applications and significance: the value serves as a natural boundary in computer architecture and memory planning because it is a high-power-of-two multiple of the basic memory unit. It frequently appears when describing RAM capacities, disk-space quotas, cache sizes, or buffer allocations in systems designed around binary addressing and block sizes. The next higher binary-scale unit is 2^31 bytes (2,147,483,648), or 2 GiB.
