 WHAT IS PARTITIONING ? Certain operating system use partitioned memory management to allow multiprogramming . • Partitioning means dividing main memory into various sections.  • These section are called as partitions.  • There are two types of partitions: 1) fixed partition .    2) variable partition.   Fixed partition  .  • In this method partitions are fixed at the time of system generation . At this time , system manager has to declear partition time.  • Fixed partition are also called static partition . On declearing fixed partition , the operating system create partition description table.  • It reduces the uses the CPU utiliisation .  • It reduces the degree of multiprogramming. .    variable partition .     In variable partition number of partition and their size are variable  • They are not defined at the time of system generation .  • These partition are created by operating systems...
