Each stack frame contains a stack pointer to the top of the frame immediately below. The stack pointer is a mutable register shared between all invocations. A frame pointer of a given invocation of a function is a copy of the stack pointer as it was before the function was invoked. [2]
The stack segment contains the call stack, a LIFO structure, typically located in the higher parts of memory. A "stack pointer" register tracks the top of the stack; it is adjusted each time a value is "pushed" onto the stack. The set of values pushed for one function call is termed a "stack frame". A stack frame consists at minimum of a return ...
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
The Zachman Framework for Enterprise Architecture, an update of the 1987 original in the 1990s extended and renamed . [6] One of the later versions of the Zachman Framework, offered by Zachman International as industry standard. Collage of Zachman Frameworks as presented in several books on Enterprise Architecture from 1997 to 2005.
Protocol stack of the OSI model. The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family.Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
In a stack machine, the operands used in the instructions are always at a known offset (set in the stack pointer), from a fixed location (the bottom of the stack, which in a hardware design might always be at memory location zero), saving precious in-cache or in-CPU storage from being used to store quite so many memory addresses or index ...
Frame (networking), a data transmission unit or network packet that includes frame synchronization information; Distribution frame, in telecommunications; Mainframe computer; Page frame, an available chunk of memory; Stack frame, a part of a call stack; A data structure in frame languages; Frame problem, in artificial intelligence
The frame pointer ($30) is optional and in practice rarely used except when the stack allocation in a function is determined at runtime, for example, by calling alloca(). For N32 and N64, the return address is typically stored 8 bytes before the stack pointer although this may be optional.
