partitioning (operatimg system ).

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...

1. ALU 2. STACK POINTER 3. PROGRAM COUNTER 4. INSTRUCTION REGISTER AND DECODER ALU ( ARITHMATIC AND LOGIC UNIT ) It is 8 bit unit In this arithmetic and logical operation are carried out . ALU contain the binary adder to perform addition substracion by 2’s complement method Data is supplied by memory devices and input ouput devices The result is typically stored in the accumulator. STACK POINTER:- Stack poiointer is a 16 bit register which contain the address of top of stack With the help of incrementer and decrementer stack pointer perform their work The stack pointer is incremented when data is push The stack pointer is decrementd when data is pop. INSTRUCTION REGISTER AND DECODER :- During the instruction fetch, the first 8 bit of instruction is transfer to the 8 bit instruction register The content of instruction register are available to the instruction decoder The output of decoder get by timing signals, ALU & data buffer. PROGRAM COUNTER:- Program coun...
