“stack”的概念、定义、翻译、参考文献-科学参考

stack

Computer

1. A linear list where all accesses, insertions, and removals are made at one end of the list, called the top. This implies access on a last in first out (LIFO) basis: the most recently inserted item on the list is the first to be removed. The operations push and pop refer respectively to the insertion and removal of items at the top of the stack. Stacks occur frequently in computing and in particular are closely associated with recursion.
2. Loosely, a linear list where accesses, insertions, and removals are made at one end or both ends of the list. This includes a pushdown stack, described above. When the earliest inserted item on the linear list is the first to be removed (first in first out, FIFO), it is a pushup stack, more properly known as a queue. When insertions and deletions may be made at both ends, it is a double-ended queue, or deque.
A stack may be implemented in hardware as a specialized kind of addressless memory, with a control mechanism to implement any of the insertion/removal regimes. See also stack processing.

1 A short version of the term protocol stack.
2 A term used by computer scientists for a data structure in which the last item added to the structure is the first to be removed.

Electronics and Electrical Engineering

See PUSH.

Geology and Earth Sciences

1. Pillar or block of rock, with near-vertical sides, standing adjacent to a present or former sea cliff. Typically it has been isolated from the main cliff by wave erosion concentrated along steeply inclined joints or faults.
2. The product of stacking. A ‘brute’ or ‘final’ stack is the end product of the standard processing of seismic-reflection data; the data can be processed further, e.g. by migration programs to produce a ‘migration’ stack.

Geography

An isolated islet or pillar of rock standing up from the sea bed, close to the shore. Initially, caves develop; some ultimately meet to form an arch. With the collapse of the roof of the arch, a stack is left.
