Answer:
a) AL will contains 0011 1100
Explanation:
In assembly language, shifting bits in registers is a common and important practice. One of the shifting operations is the SHR AL, x where the x specifies that the bits be shifted to the right by x places.
SHR AL, 2 therefore means that the bits contained in the AL should be shifted to the right by two (2) places.
For example, if the AL contains binary 1000 1111, the SHR AL, 2 operation will cause the following to happen
Original bit => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) |
Shift once to the right => | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | (0) | (0) |
Notice;
(i) that there are two shifts - one at a time.
(ii) that the bits in bold face are the bits in the AL after the shift. Those that in regular face are those in the carry flag.
(iii) that the new bits added to the AL after a shift are the ones in bracket. They are always set to 0.
Answer: Economic
Explanation: Economic impact can be explained as the effect of a certain action, policy or action on the economy of an organization, country measured in terms of business revenue, gain or profit, impact on manufactory or production cost, inflation, monetary value and so on.
In the scenario above, the economic effect or impact of implementing information technology is highlighted in terms of lower cost of market participation, shrinkage in size of firms due to external participation and so on.
In order to prevent ports that are serving network hosts from being considered as best paths, BPDU guard should be enabled to block bpdus.
<h3>What are BPDU used for?</h3>
A bridge protocol data unit (BPDU) is known to be a kind of a data message that is known to be often transmitted in a local area network to be able to know or find loops in that given network topologies.
Hence, in the case above, In order to prevent ports that are serving network hosts from being considered as best paths, BPDU guard should be enabled to block bpdus.
See full question below
. In order to prevent ports that are serving network hosts from being considered as best paths, what should be enabled to block BPDUs?
a. BPDU filter
b. BPDU guard
c. root guard
d. BPDU drop

Answer:
Following are the code to this question:
def capital(val):#defining a method that takes string value as parameter
x=True#defining boolean variable
r=''#defining string variable
for i in val:#defining loop to convert the first character into upper case
if i.isalpha() and x:#defining condition to check input value is string
r=r+i.upper()#change value into uppercase and hold value in r variable
x=False#assign value false in boolean variable
elif i=='.' or i=='?' or i=='!':#check symbols
r=r+i#add value in r variable
x=True#assign value True in boolean variable
else:
r=r+i#add all value in r variable
return r#return r variable value
val=input()#input value in val variable
print(capital(val))#called the function which print the return value
Output:
please find the attachment.
Explanation:
- In the above python program, a method "capital" is declared, which accepts a "val" a string value in its parameter, and inside the method one boolean "x" and one string "r" variable is used, in which r stores return value.
- In the next step, for loop is declared, inside the loop, the conditional statement is used, in if the block it checks string value and converts the first character into upper case and assigns value false in the boolean variable.
- In the next step, elif block is defined that adds value in r variable and at the last, it will return function value, at the last step "val" variable is declared that input value from the user and pass into the method and print its return value.
