What is dynamic relocation?
Dynamic relocation is where data currently stored in the computer memory is relocated to other parts of the computer. This process creates more efficient memory storage while a program is still active.
What is relocation processing?
After the runtime linker has loaded all the dependencies required by an application, the linker processes each object and performs all necessary relocations. During the link-editing of an object, any relocation information supplied with the input relocatable objects is applied to the output file.
What is the difference between static and dynamic relocation?
Static Relocation – Program must be relocated before or during loading of process into memory. Program must always be loaded into same address space in memory, or relocator must be run again. Dynamic Relocation – Process can be freely moved around in memory.
Which registers are used in dynamic relocation?
Dynamic relocation is performed by hardware and is simple – it requires two special registers, a simple addition, and a simple comparison. This is very inexpensive in computing terms.
What is the use of MMU?
An important function of the Memory Management Unit (MMU) is to enable the system to run multiple tasks, as independent programs running in their own private virtual memory space.
What does a relocation register do?
A hardware element that holds a constant to be added to the address of each memory location in a computer program running in a multiprogramming system, as determined by the location of the area in memory assigned to the program.
What is relocation explain with its types?
Relocation is the process of connecting symbolic references with symbolic definitions. For example, when a program calls a function, the associated call instruction must transfer control to the proper destination address at execution.
Why do companies relocate employees?
The reasons for relocating an employee can include to open a new location, fill an open position in another location, career development, and more.
What is the difference between static and dynamic?
In general, dynamic means energetic, capable of action and/or change, or forceful, while static means stationary or fixed. In computer terminology, dynamic usually means capable of action and/or change, while static means fixed.
What is static and dynamic allocation?
When the allocation of memory performs at the compile time, then it is known as static memory. When the memory allocation is done at the execution or run time, then it is called dynamic memory allocation. 2. The memory is allocated at the compile time. The memory is allocated at the runtime.
What is relocation register?
[‚rē·lō′kā·shən ‚rej·ə·stər] (computer science) A hardware element that holds a constant to be added to the address of each memory location in a computer program running in a multiprogramming system, as determined by the location of the area in memory assigned to the program.
What is dynamic loading in OS?
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.

What is a relocation action in SQL Server?
A relocation action describes how to patch the code or data contained at r_offset. The r_info gives both the symbol table index with respect to which the relocation must be made and the type of relocation to apply. The r_addend specifies a constant addend used to compute the value stored in the relocatable field.
What is the relocation offset of the puts() method?
The relocation offset is the address 0x804C00C, the same address that the puts () PLT jumps into. Assuming that puts () is being called for the first time, the dynamic linker has to resolve the address of puts () and place its value into the GOT entry for puts ().
What are relocation entries in a link editor?
Relocation entries describe how to alter the following instruction and data fields. The link editor merges one or more relocatable files to form the output. It first decides how to combine and locate the input files, then updates the symbol values, and finally performs the relocation.
