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 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 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.
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.
Is single partition a fixed partition?
yes
How is partitioned allocation different from relocatable partitioned allocation?
Partitioned allocation is a fixed memory allocation technique which memory spaces are divided into smaller fixed partition, while Relocatable partitioning use variable and repartitioning technique
What is another name for a fixed partition?
Static Partition
What is 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 are the advantage of worst fit?
it has advantage in variable sized fixed partition memory location when the left space are consecutive since they are merged to make large sized
Why it is necessary to partition main memory?
Its not.
Difference between partition page segmentation in memory allocation?
In partition memory is divided in to fixed/variable size of the partitions . Programs are stored in partitions.In page allocation memory and programs are divided into small pages . These program pages are stored in the memory.One processor pages are need not allocate the continuous pages in memory.segmentation is the grouping of information that is treated as a logical entity.
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
