Memory protection is normally done by
-
The processor and the associated hardware
-
The operating system
-
The compiler
-
The user program
Correct Answer
A. The processor and the associated hardwareExplanation
Memory protection is a crucial aspect of computer systems to prevent unauthorized access or modification of memory. The responsibility of memory protection lies with the processor and the associated hardware. The hardware implements mechanisms like memory management units (MMUs) and access control lists (ACLs) to ensure that each process can only access its allocated memory and cannot interfere with other processes' memory. The processor enforces these protections by checking memory access requests against the defined permissions. The operating system, compiler, and user program may play a role in configuring these protections, but the actual implementation and enforcement are done by the processor and associated hardware.Rate this question:

In wireless ad-hoc network
-
Access point is not required
-
Access point is must
-
Nodes are not required
-
None of the mentioned
Correct Answer
A. Access point is not requiredExplanation
In a wireless ad-hoc network, an access point is not required because this type of network is decentralized and does not rely on a central access point for communication. Instead, all nodes in the network can directly communicate with each other, forming a self-configuring network without the need for an access point. This allows for more flexibility and scalability in the network, as nodes can easily join or leave the network without disrupting the overall connectivity.Rate this question:
