Computer number format with a specific number of bits are used to represent varying things and have specific names. A "byte" is a bit string containing the number of bits needed to represent a character. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. In many computer architectures, the byte is used to address specific areas of memory. For example, even though 64-bit processors may address memory sixty-four bits at a time, they may
Overhead (computing) 349 byte, resulting from the UTF-8 encoded XML, correlates to a size overhead of 8625% over the original integer representation. Overhead (computing) In computer science, overhead is any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to perform a specific task. It is a special case of engineering overhead. Overhead can be a deciding factor in software design, with regard to structure, error correction, and feature inclusion. Examples of computing overhead may be found in functional programming, data transfer, and data structures. A programmer/software engineer may have a choice of several algorithms, encodings,
