In a multi-tiered network the work of the entire network is centralized. the work of the entire network is balanced over several levels of servers. processing is split between clients and servers. processing is handled by multiple, geographically-remote clients.

Work of complete network is managed and balanced through different server stages.

Explanation:

Multi-tiered network is network pattern that takes place between client  and server through multiple levels .There are different stages for processing of functions, management,operation sector etc.

These layers are separated from each other in physical as well as objective manner.Task in this network architecture is carried out through multiple levels of network servers .Other options are incorrect because numerous remote client, server and client processing and centralization of work is not the function mechanism of multi-tiered network.

a = 6, b = 0

Explanation:

The loop ran 3 times before b == 0. "while ((b != 0)" is essentially saying: 'While b is not equal to 0, do what's in my loop'. Same general thing with "&& ((a / b) >= 0)". The "&&" is specifying that there should be another loop condition, while the rest states: 'as long as a ÷ b is greater than 0, do what's in my loop'. If both of these conditions are met, the loop will run, It will continue this until the conditions are not met. Hope that helped! :)
