          Some Defenation of Operating system  This defenation is very important of DAE CIT studants.  Q1.  What are the two main purposes of an operating system? Answer. To provide ad environment for computer use to execute programs on computer hardware in a convenient and efficient manner. To allocate the separate resources of the computer as needed to solve the problems given. The allocation process should be as fair and efficient as possibele. Q2. What is the fundamental goal of computer systems? Answer. To execute user programs and solve user problems. Q3. What is the main advantage of multi programming? Answer. Multiprogramming make efficient use of the CPU by overlapping the demands for the CPU and its I/O devices from various users. It attempts to increase CPU utilizaion by always having something for the CPU to execute.       That is clearly in this daigram..

Want Answers 3 2 ANSWERS Nishant Varma 20 bits cannot be stored in 16 bits. So to generate a 20 bit value, information from 2 registers need to be combined. In 8086 this is done by adding the segment register value offset by 4 bits with value from another register      xxxx  xxxx xxxx xxxx 0000       +  0000 yyyy yyyy  yyyyy  yyyy where x represents the bits in segment registers and y represents the bits in the other register.
