Explain FIFO Page replacement algorithm.
FIFO policy: This policy only removes pages in the order they entered in the main memory. By using this policy we simply eliminate a page based upon the time of its arrival in the memory. For illustration if we have the reference string: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames here 3 pages can be in memory at a time per process, after that we have 9 page faults as demonstrated:
If frames are increased say to 4, after that number of page faults also arises, to 10 in this case.
Reg data type as Combinational element module reg_combo_example( a, b, y); input a, b; output y; reg y; wire a, b; always @ ( a or b) begin y = a & b; e
There are two methods for organising the associative memory based on bit slices: Bit parallel organisation: In this organisation every bit slices which are not masked off,

Mating: Therefore once our GA agent has chosen the individuals lucky sufficient as actually there fit enough to produce offspring then we next determine how they are going to
Perform the - 48 - 23 operations using the 2's complement method. Ans. - 48 - 23 = - 48 + (-23) -48 = 1 1 0 1 0 0 0 0 -23 = 1 1 1 0 1 0 0 1 = -71
What is linear bounded automation? A linear bounded automation is restricted type of Turing machine where in the tape head isn't permitted to move off the portion of the tape
Absolute addressing and Implied addressing A fixed address is specified and also called as direct addressing. The location of data is implied by instruction itself, so no
