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...

Free notes of the operating system some imp questions

 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...

  What is a constructor ? Why it is called so? “A constructor is a special member function of a class . Its task is to initialize the objects of its class. ” It is special because its name is same as that of the class to which it belongs. The constructor is invoked whenever an object of its associated class is created. It is called constructor because it constructs the values of data members of the class. A constructor can never return any value. Hence ,it is written with no return type ( even void is not written ). Whenever a class contain a constructor like one above , it will be initialized automatically , whenever an object of the class is created. i.e. the declaration – integer int1; This not only creates the object int1 of type integer , also initializes its data members m and n to zero . Give the characteristics of a constructor function .or Syntax rule for writing constructors. The constructor name is always same as the class name . They do not have ret...
