Answer:

import numpy as np

a = int(input ("Enter a"))

b = int(input ("Enter b"))

c = int(input ("Enter c"))

d = int(input ("Enter d"))

c1 = int(input ("Enter c1"))

c2 = int(input ("Enter c2"))

array1 =[[a, b],[c, d]]

A = np.array (array1)

B = np.array ([c1, c2])

X = np.linalg.inv (A).dot (B)

print (X)

Explanation:

let ax + by =c1

     cx + dy =c2

We have used the above NumPy library that has the methods for matrix calculation, and here we have used matrix multiplication, and the inverse of a matrix to find the value of x and y.

We know AX=B

X = inv A. B

And this we have used above. We can calculate inv A and do matrix multiplication using NumPy. And thus we get the above solution.

Solution :

'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.

Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true.  If one of the P or Q is not true, then outcome result will be false.

In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.

Therefore, using the AND operation of the customers as :

Customer     Wireless     Discount     Outcome

   A                   N                   N             FALSE

   B                   Y                   N             FALSE

  C                   N                   Y              FALSE

   D                   Y                   Y             TRUE

Answer:

Automatic and Explicit Buffering.

In the case of explicit buffering, the length of the queue is provided while in automatic buffering the queue size needs to be indefinite. In automatic buffering there is no need to block the sender while coping the message. While in explicit buffering the sender is blocked for the space in queue.

No memory is being wasted in explicit buffering.

Send by Copy and Send by Reference.

By using the send by copy method, the receiver is not able to change the state of parameter while send by reference allow. The advantage of using the send by reference method is that it allows to change a centralized application to its distributed version.

Fixed-sized and Variable-sized Messages.

In fixed size messaging refers, the buffer size is fixed. This means only a particular number of messages can only be supported by the fixed size buffer. The drawback of the fixed size messages is that they must be a part of fixed size buffer. These are not a part of variable size buffer. The advantage of variable size message is that the length of the message is variable means not fixed. The buffer length is unknown. The shared memory is being used by the variable size messages.
