In computing, a hex dump is a hexadecimal view (on screen or paper) of computer data, from RAM or from a file or storage device. Looking at a hex dump of data is commonly done as a part of debugging, or of reverse engineering.
In a hex dump, each byte (8-bits) is represented as a two-digit hexadecimal number. Hex dumps are commonly organized into rows of 8 or 16 bytes, sometimes separated by whitespaces. Some hex dumps have the hexadecimal memory address at the beginning and/or a checksum byte at the end of each line.
Although the name implies the use of base-16 output, some hex dumping software may have options for base-8 (octal) or base-10 (decimal) output. Some common names for this program function are hexdump, od, xxd and simply dump or even D.

Famous quotes containing the word dump:
“Mrs. Van Daan’s grizzling is absolutely unbearable; now she can’t any longer drive us crazy over the invasion, she nags us the whole day long about the bad weather. It really would be nice to dump her in a bucket of cold water and put her up in the loft.”
—Anne Frank (1929–1945)
