Hash list — In computer science, a hash list is typically a list of hashes of the data blocks in a file or set of files. Lists of hashes are used for many different purposes, such as fast table lookup (hash tables) and distributed databases (distributed hash … Wikipedia
Page table — A page table is the data structure used by a virtual memory system in a computer operating system to store the mapping between virtual addresses and physical addresses. Virtual addresses are those unique to the accessing process. Physical… … Wikipedia
Linear hash — Linear Hashing is a dynamic hash table algorithm invented by Witold Litwin (1980) [ Citation | first1=Witold | last1=Litwin | title=Linear hashing: A new tool for file and table addressing | journal=Proc. 6th Conference on Very Large Databases |… … Wikipedia
Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… … Wikipedia
Rainbow table — A rainbow table is a lookup table offering a time memory tradeoff used in recovering the plaintext password from a password hash generated by a hash function, often a cryptographic hash function. A common application is to make attacks against… … Wikipedia
