Q. Explain Error Detection and Correction Codes?
Before we wind up data representation in reference of today's computers one should determine about code that helps in correction and recognition of errors. Computer is an electronic media hence there is a probability of errors at the time of data transmission. These kinds of errors can result from disturbances in transmission media or external environment. But what is an error in binary bit? An error bit alters from 0 to 1 or 1 to 0. One of simplest error detection codes is known as parity bit.
Not Recently Used Page Replacement Algorithm The not recently used abbreviated as NRU page replacement algorithm works on the subsequent principle: while a page is referenced,
Magnify a triangle with vertices A = (0,0), B = (3,3) and C = (6,4) to twice its size in such a way that A remains in its original position.

Q. Requirements of decision support system? a) Fast computation A decision maker is able to perform a large number of computations very quickly and that too at a low cost
Explain with the help of examples FIFO algorithms? FIFO policy: This policy easy removes pages in the order they arrived into the main memory. By using this policy we easily
Virtual Memory is a way of extending a computer's memory by using a disk file to replicate add'l memory space. The OS remain track of these add'l memory addresses on the hard disk
Discuss the concept of segmentation? Segmentation is method for the non contiguous storage allocation. This is different from paging as this supports user's view of his program
