  2.    Adhoc mode
  3.    Infrastructure mode
  4.    Anonymous mode
 Discuss Question
Answer: Option B. -> Adhoc mode
Answer: (b)
Adhoc mode is a framework in which devices or stations communicate directly with each other, without the use of an Access Point (AP). Ad-hoc mode is also referred to as peer-to-peer mode or an Independent Basic Service Set (IBSS).
Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required.
Question 115. In operationg system, Round Robin Scheduling means :
  1.    A memory allocation policy
  2.    A kind of scheduling
  3.    Repetition policy
  4.    A process allocation policy
 Discuss Question
Answer: Option B. -> A kind of scheduling
Answer: (b)
Round robin is the scheduling algorithm used by the CPU during the execution of the process. Round robin is designed specifically for time-sharing systems.
It is similar to the first come first serve scheduling algorithm but the preemption is the added functionality to switch between the processes.
Question 116. When does a Page fault occur?
  1.    A program accesses a page of main memory
  2.    There is an error in a specific page
  3.    A program accesses a page not currently in the main memory

Answer: (c)
When the page (data) requested by a program is not available in the memory, it is called a page fault.
It occurs when a program accesses a page that has been mapped in address space but has not been loaded in its main memory (RAM). This usually results in the application being shut down.

Answer: (b)The First supercomputer was Cray XMP-14 which was installed at National Centre for Medium Range Weather Forecasting, New Delhi, in 1989. Param was developed by C-DAC Pune in 1991.
Question 120. WiMAX stands for
  1.    Worldwide Interoperability for Microwave Access
  2.    Wireless Interoperability for Microwave Access
  3.    Wired Interoperability for Microwave Access
  4.    Worldwide Infrastructure for Microwave Access
 Discuss Question
Answer: Option A. -> Worldwide Interoperability for Microwave Access
Answer: (a)
