0x100000

0x100000 is a hexadecimal number. In decimal representation, it is equal to 1,048,576. This value is significant in computing as it represents 2 to the power of 20, or 2^20. One megabyte (MB) is commonly defined as 1024 kilobytes (KB), and since one kilobyte is 1024 bytes, one megabyte is 1024 * 1024 bytes, which equals 1,048,576 bytes. Therefore, 0x100000 bytes is equivalent to 1 megabyte in the binary prefix system, often referred to as a mebibyte (MiB) to distinguish it from the decimal megabyte (1,000,000 bytes).

This specific value, 0x100000, frequently appears in memory addressing schemes, file sizes, and data transfer rates within computer systems. For instance, when discussing memory capacity, a value of 0x100000 often signifies one megabyte of RAM or storage space. Similarly, in programming contexts, it might be used as a mask or an offset in memory operations. The use of hexadecimal notation is common in computing due to its efficient representation of binary data, where each hexadecimal digit corresponds to exactly four binary digits (bits).
