What else can I help you with?
When does segmentation fault occur for a prog?
You either reference memory that is non existent, or you attempt to modify memory that is read only. This is usually a result of failure to properly initialize or use pointers or arrays.
What is static and dynamic memory?
A computer is built to contain two kinds of memory. There is static memory, which stays in the computer after it is powered off. Then there is dynamic memory, which is memory that is only accessible while the computer is on. The hard drive is an example of static memory, while RAM is an example of dynamic memory.
Define primary memory?
primary memory is built in memory on a computer it is the main type of memory.... eg RAM ROM and HDD
Can you deallocate memory of a null pointer?
In the case of C, execution halts with a segmentation fault because the literal address of NULL is never allocated to a running program.
Why paging is faster than segmentation?
Paging is a technique with the help of which we can divide the memory into pages which help us to easly access the files and it also decreases the Execution time (Saves SYSTEM time). It also creates a mirage of Memory.
What is segmentation in computer architecture?
Segmentation is part of physical memory ares.
What are the most common problems associated with computer memory?
* Stack overflows * Heap overflows * Segmentation faults * Null or non-existent memory addresses
How does memory segmentation increase processors speed?
The segmentation function maintains a segment table that includes physical addresses of the segment, size, and other data. Segmentation speeds up a computer's information retrieval by assigning related data into a “segment table” between the CPU and the physical memory.
What is the difference between segmentation and compaction?
Segmentation involves dividing memory into variable-sized partitions to allocate memory dynamically, while compaction rearranges memory to reduce fragmentation by moving allocated memory blocks closer together. Segmentation deals with memory allocation, while compaction improves memory utilization.
Write short notes on segmentation?
segmentation is scheme in which the logical memory is broken into a number of variable length blocks called SEGMENTATION.
What are the disadvantages of memory segmentation in 8086?
disadvantages of memory segmentation
What is the pattern of repeated segmentation called?
The pattern of repeated segmentation is called segmentation fault or segfault. This occurs when a program tries to access a memory segment that it doesn't have permission to access, leading to a segmentation violation error.
In computer networking what is segmentation?
I am looking for this answer too.
What is segmantation?
Divide the memory block into different sizes is called segmentation.
8086 micro processor memory segmentation and advantage and rules?
hhh
How Intel Pentium supports segmentation and paging?
The Intel Pentium supports pure segmentation and segmentation with paging. The processor creates logical addresses, which are mapped to physical addresses by the segmentation unit. Those addresses may point to physical addresses within memory or paged swap space.
What does segmentation concerning humans mean?
The term human segmentation is used for the technique of seperating individuals from a crowd in images, videos and related computer based applications. Human segmentation is a special branch of image segmentation. The goal is usually to provide data which is better and easier to analyze.
