In computer programming, the name .bss or bss is used by many compilers and linkers for the portion of an object file or executable containing statically-allocated variables that are not explicitly initialized to any value. It is often referred to as the "bss section" or "bss segment".
What does BSS stand for in telecom?
business support system
.bss ("Block Started by Symbol"), in compilers and linkers. Backup sync share, an emerging category of software products. Base station subsystem, in mobile telephone networks. Basic Service Set, the basic building block of a wireless local area network (WLAN)
Abbreviated as BSS, Basic Service Set is a component of the IEEE 802.11 WLAN architecture. When one access points (AP) is connected to wired network and a set of wireless stations it is referred to as a Basic Service Set (BSS).
The BSS segment, also known as uninitialized data, is usually adjacent to the data segment. The BSS segment contains all global variables and static variables that are initialized to zero or do not have explicit initialization in source code.
Business support systems (BSS) are the components that a telecommunications service provider (or telco) uses to run its business operations towards customers. Together with operations support systems (OSS), they are used to support various end-to-end telecommunication services (e.g., telephone services).
Welcome to the Bachelor of Specialized Studies (B.S.S.) program at OHIO. The B.S.S. program allows students to create a faculty-approved, multidisciplinary degree program tailored to their individual interests and needs.
Stack is used for static memory allocation and Heap for dynamic memory allocation, both stored in the computer's RAM . Variables allocated on the stack are stored directly to the memory and access to this memory is very fast, and it's allocation is dealt with when the program is compiled.
When you declare a variable in a function, it always goes on the stack. So your variable Member* m is created on the stack. Note that by itself, m is just a pointer; it doesn't point to anything. You can use it to point to an object on either the stack or heap, or to nothing at all.
In certain programming languages including C and Pascal , a heap is an area of pre-reserved computer main storage ( memory ) that a program process can use to store data in some variable amount that won't be known until the program is running.
C's volatile keyword is a qualifier that is applied to a variable when it is declared. It tells the compiler that the value of the variable may change at any time--without any action being taken by the code the compiler finds nearby. The implications of this are quite serious.
Presumably you mean heap from a memory allocation point of view, not from a data structure point of view (the term has multiple meanings). A very simple explanation is that the heap is the portion of memory where dynamically allocated memory resides (i.e. memory allocated via malloc ).
In computer programming, a static variable is a variable that has been allocated "statically", meaning that its lifetime (or "extent") is the entire run of the program.
A static data structure is an organization or collection of data in memory that is fixed in size. This results in the maximum size needing to be known in advance, as memory cannot be reallocated at a later point. Arrays are a prominent example of a static data structure.
Allocating Storage Space for Initialized Data
|DB||Define Byte||allocates 1 byte|
|DW||Define Word||allocates 2 bytes|
|DD||Define Doubleword||allocates 4 bytes|
|DQ||Define Quadword||allocates 8 bytes|
All allocation made by malloc(), calloc() or realloc() are stored on the heap, while all local variables are stored on the stack. All global and static variables are stored in the data segment, while constants are stored in the code segment. Memory via malloc() is taken from the heap.
14.1.8 Stack vs Heap Allocation. When a program is loaded into memory, it is organized into three areas of memory, called segments: the text segment, stack segment, and heap segment. The text segment (sometimes also called the code segment) is where the compiled code of the program itself resides.
The AVR microcontroller's memory is divided into Program Memory and Data Memory. Program Memory (ROM) is used for permanent saving program being executed, while Data Memory (RAM) is used for temporarily storing and keeping intermediate results and variables.
Usually they are stored in read-only data section (while global variables' section has write permissions). So, trying to modify constant by taking its address may result in access violation aka segfault. But it depends on your hardware, OS and compiler really.
There are four segments used in 8086, code segment, data segment, stack segment and extra segment. Segment registers are used to contain the base addresses of the above mentioned segments. They are 16 bit registers.
By considering that the memory is divided into four segments: data, heap, stack, and code, where do global variables, static variables, constant data types, local variables (defined and declared in functions), variables (in main function), pointers, and dynamically allocated space (using malloc and calloc) get stored
