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...
