What is the difference between fixed and variable partition?
in the fixed partition the partition is once allocated is fixed. in fixed partition more memory wastage because of internal & external fragmentation.... in variable partition when a process comes then according to need of process the size of memory is allocated to the process
What is fixed partition memory?
The first attempt to allow for multiprogramming used fixed partitions (also called static partitions) within the main memory-one partition for each job. Because the size of each partition was designated when the system was powered on, each partition could only be reconfigured when the computer system was shut down, reconfigured, and restarted. Thus, once the system was in operation the partition sizes remained static.
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.
Is cache memory necessary?
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.

advantages of static partition allocation scheme?
It supports multiprogramming since multiple processes can be stored inside the main memory.
What type of partition does Linux use when it does not have enough memory?
A swap partiton because it is a dedicated partition and not a file
Is it possible to do multiprogramming with only one partition of the memory?
is it possible to do multiprogramming with only one partition
What is the difference between internal memory and backing storage?
Backing storage is where information can be repeatedly stored and modified in a permanent way and main storage is main storage is understood to be the program addressable memory that houses the executable and data necessary to launch and run various systems and programs. More commonly referred to as primary storage or memory, main storage directly interfaces with the CPU, which reads the instructions connected with the executable and performs the tasks necessary to handle the data. All data necessary for the effective function of programs saved on the hard drive is maintained in the main storage.
What partition hosts the main Windows 7 operating system files?
root partition
In a UNIX server what can take the form of a disk partition or it can be in a file?
Vitual Memory
Difference between fixed partition and dynamic partition in memory management?
Fixed partitions have fixed size and usually cannot be easily expended or shrunk. Dynamic partitions can change size by themselves when they need it. There are some advantages of using fixed partitions because you control its size. It might happen that you can run out of free space when you are using dynamic partitions.
