1 gigabyte is equal to-

Explanation

The correct answer is 1024 megabytes. Key Points 1 gigabyte = 2 30 bytes = 2 10 × 2 20 bytes Since 1 megabyte = 2 20 bytes 1 gigabyte = 2 10 × megabytes 1 gigabyte = 1024 megabytes Therefore option 3 is correct. Important Points The smallest unit of memory is called a bit. Bit stands for binary digit. The memory of a computer is measured in Bytes The storage capacity of a hard disk is measured in Megabytes, Gigabytes, and Terabytes. Additional Information Memory Size is as follows: Term Size (in the power of 2) Byte (B) 8 bits Kilobyte (KB) 2 10 bytes Megabyte (MB) 2 20 bytes Gigabyte (GB) 2 30 bytes Terabyte (TB) 2 40 bytes Petabyte (PB) 2 50 bytes Exabyte (EB) 2 60 bytes Zettabyte (ZB) 2 70 bytes Yottabyte (YB) 2 80 bytes
