What is fixed partition main memory management technique in operating systems?
A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time. The main memory (which is the volatile memory where active programs and data are held during use), is divided into partitions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run. So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size. And a process is loaded into a partition big enough to hold it.
What is external fragmentation in operating system?
External fragmentation refers to the division of free storage into small pieces over a period of time, due to an inefficient memory allocation algorithm, resulting in the lack of sufficient storage for another program because these small pieces are not contiguous.
Name the crop was adversely affected at the time of partition?
the crop which was affected at the time of partition?
Where is the partition table on a hard drive found?
Most of the time the boot partition and the system partition are the same partition on the drive C.

What is next fit algorithm?
Memory is used more evenly because the search for a free partition does not always start at the beginning of the list (forcing higher use of these partitions and lower use of the partitions at the end of the list).
How long does shrinking a partition take in Linux?
There is no set amount of time. It can vary tremendously, depending on the type of partition, the size of the partition, and the speed of the computer.
What is a swap partition in Linux?
When you run out of memory, some of the data is stored in SWAP, so memory can be used for something else. Also, some files might be saved to swap, so it takes less time to find and read them. And when you hibernate your PC, the contents of RAM get saved onto the SWAP partition, but this only works when your SWAP is larger than amount of your RAM and amount of SWAP already used combined.
How does fragmentation affect interior species?
As fragmentation occurs, the interior area of the patch decreases. This results in a reduced habitat area for interior species. Thus, interior species experience a reduction in population over time as they lose habitat to fragmentation.
What was the area of India at the time of partition?
it is so dabba
Is C plus plus good for Embedded programming or not?
C and C++ programming is good for embedded programming. However, embedded implies long running, and that means the possibility of memory fragmentation. You will need to spend time working out or acquiring a method of memory management, such as the use of Smart Pointers and Garbage Collection. This is not a trivial task, but it is a necessary task.
What is the similarties between memory management fragmentation and disk fragmentation?
Fragmentation is the result of an inefficient use or allocation of memory space. It is not usually a catastrophic occurrence, but it can cause problems in operating efficiency. In both main memory as well as on disk, data is stored in blocks. The blocks are all uniform in size but the data may or may not be. In other words, data that doesn't fill up the entire block ends up wasting space. This is called internal fragmentation. Alternatively, external fragmentation refers to data that requires multiple blocks to store, but which can't be contiguously located. External fragmentation may cause problems in primary storage, but it's not as big a deal on disk. Data most likely won't load into primary storage if there are not enough contiguous blocks available to house it. A disk on the other hand, will accept data in non-contiguous blocks, but this will cause performance issues. The disk controller will have to look up the address for each block of data, and the moving parts of the drive will have to align in order to use those blocks. This means that seek, latency, and transfer time issues will intensify due to the number of times the blocks must be located in order to read and/or write disk data.
