Answer: Option C. -> WAN
Answer: (c)
A Wide Area Network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports.
Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations.
In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location.

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.

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.

Answer: Option C. -> 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: Option A. -> Worldwide Interoperability for Microwave Access
Answer: (a)
WiMAX stands for Worldwide Interoperability for Microwave Access. It is a family of wireless communication standards based on the IEEE 802.16 set of standards, which provide multiple physical layers (PHY) and Media Access Control (MAC) options.
WiMAX is sometimes referred to as “Wi-Fi on steroids” and can be used for broadband connections, hotspots, etc.
