Answer:
Out of the two methods The 2nd method is a better option for implementing several stacks and arrays using the single array system this is because Method 2 makes efficient use of the available space
Explanation:
A) Method 1 ( Divide the given single array in the size of n/k.)
How to use method 1 to implement several stacks involves :i) To implement several stacks through an array (x) is by dividing the array in n/k parts.
ii) The k represents the slots in which the different stacks will be placed and the n represents the size of the array x.
iii) If you need to implement at least two stacks place the first stack in the slot of a [0] to a [n/k - 1], and another stack in the slot of a[n/k] to a[2n/k-1].
note: The disadvantage of this method is that the use of the space of the array is not much efficient. therefore method 2 is better
How to use method 1 to implement queues involves :i) queues can also be implemented through an array. applying the same method above
ii) Divide the array in slots and place the queues in that slots.
This method has a problem with the efficient utilization of the space.therefore method 2 is preferred
B) Method 2 ( uses the space efficiently ) uses two more arrays to implement stacks which are : Top_array and Next_array
how to use method 2 to implement several stacksi) Store the indexes of the next item that will also be stored in all stacks in this initial stack
ii)The initial actual array is x[] and this will store the stacks.
iii)Simultaneously with several stacks, the stack which contain the free slots in the array x[] will also be maintained.
iv) The entries of the Top_array[] will be initialized to -1. This implies that all the stacks are empty.
v) Firstly the entries of the array Next_array[i] will be initialized to i+1, since all the slots initially are free and are pointed to the next slot.
vi) Initialize The top of the free stack that is maintaining the free slots as 0.
vii) The complexity of push () (method to insert an element) and pop () (method to delete an element) operations by using this method is O (1).
How to use method 2 to implement several queuesThe same method applicable to implementing several stacks is used here but with a difference is the presence of three extra arrays which are :
Front_array[] = indicates the number of queues. This array stores the indexes of the front elements of the stacks.
Rear_array[] = determines the sizeof the array k . This array stores the indexes of the last elements of the stacks.
Next_array[] = The array n indicates the size of the single array say x. This array stores the indexes of the next items that is being pushed.
i) The initial actual array is a[] which will store the queues. The free slots will also be maintained.
ii)The entries of the Front_array[] will be initialized to -1. This means that all the queues are empty initially
ii) Initially the entries of the array Next_array[i] will be initialized to i+1, since all the slots initially are free and are pointed to the next slot.
iv) Apply The complexity of enqueue () and dequeue () by using this method is O (1).

A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.

Assuming a positive output pulse (LHL), what would the propagation
delay and rejection time be?
The rejection time (time for the output to remain stable at low after input changes from high to low) is also 0.05 ns.
How to determine the delaysPropagation Delay:
The propagation delay (tPHL) is given as 0.05 ns (nanoseconds).
This represents the time it takes for the output to transition from a high to a low level after the input changes from a high to a low level.
Propagation Delay (tPHL) = 0.05 ns
Rejection Time:
The rejection time (tRHL) is the minimum time required for the output to remain stable at a low level after the input changes from a high to a low level before the output starts to transition.
Rejection Time (tRHL) = tPHL
Hence = 0.05 ns

Servers can be designed to limit the number of open connections. For example, a server may wish to have only N socket connections at any point in time. As soon as N connections are made, the server will not accept another incoming connection until an existing connection is released. Please write pseudo-code to implement the synchronization using semaphore.
Answer:
The pseudocode is as follows:
open_server()
connections = N
while (connections>0 and connections <=N):
if(new_client == connected):
connections = connections - 1
for i in 1 to N - connections
if (client_i == done()):
releast_client(client_i)
connections = connections + 1
Explanation:
One of the functions of a semaphore is that, it is a positive variable whose value will never fall below 1. It is often shared among threads in order to keep a process running.
Having said that, what the above pseudocode does is that:
Once the server is opened, it initializes the number of connections to N.
When a new client, the semaphore decreases the number of connections is reduced by 1.
Similarly, when an already connected client is done, the client is released and the number of connections is increased by 1.
This operation is embedded in a while loop so that it can be repeatedly carried out.
