<span>Two-tiered client/server architecture.
The two-tier is based on Client Server architecture. The two-tier architecture is like client server application. The direct communication takes place between client and server. There is no intermediate between client and server. Because of tight coupling a 2 tiered application will run faster</span>
It is true that in the array implementation of a queue, the pop operation is most efficient if the front of the queue is fixed at index position. The correct option is a.
<h3>What is pop operation? </h3>
The removal of an element is referred to as a pop operation. Again, because we only have access to the element at the top of the stack, we can only remove one element. We simply take the top of the stack off.
A push operation decrements the pointer before copying data to the stack; a pop operation copies data from the stack before incrementing the pointer.
The pop operation in an array implementation of a queue is most efficient if the queue's front is fixed at index position.
Thus, the correct option is a.

Answer:
Differ in the quality of their transmission.
Explanation:
For example, when using the public phone box, wired transmission is done not wireless as in cell phones. Public phone box use electronic signals transmitted through a cable network to send voice data which are not very effective for long distance communication.
However, cell phones wirelessly send electromagnetic wave signal to a cell tower close to the caller and then the information is then transmitted to cell tower close to the receiver within a split of a second. This method of communication has much advantages.
Explanation:
Here, in the given statement, maximum flow capacity of the ALOHA channel = 18.4% = 0.184
Then, the stations N share 56 kbps
And, the channel rate = 
Then, the outputs of the wach stations is 
, the output of the bits/ sec by each stations = 
So, The output of the N stations is 10 bits/sec on the channel that having 
Finally, N = 
I'd say
False
NoSQL or the non-rational databases are document oriented
and distributed. Unlike the SQL or the relational databases which are
structured, NoSQL deals with a huge amount of unstructured data and offer
greater flexibility. NoSQL are more like file folders, gathering related
information of all types.
