Answer:
total_owls = 0
num_owls_A = int(input())
num_owls_B = int(input())
total_owls = num_owls_A + num_owls_B
print("Number of owls:", total_owls)
Explanation:
Initialize the total_owls as 0
Ask the user to enter num_owls_A and num_owls_B, convert the input to int
Sum the num_owls_A and num_owls_B and set it to the total_owls
Print the total_owls
avg_owls=0.0
num_owls_zooA = int(input())
num_owls_zooB = int(input())
num_owls_zooC = int(input())
num_zoos = 3
avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos
print('Average owls per zoo:', int(avg_owls))
There is a problem while you are trying the calculate the average owls per zoo.
As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos
Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)

Cloud computing gives you the ability to expand and reduce resources according to your specific service requirement.
a. True
b. False
Answer:
a. True
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
In Computer science, one of the most essential characteristics or advantages of cloud computing is rapid elasticity.
By rapid elasticity, it simply means that cloud computing gives you the ability to expand and reduce resources according to your specific service requirement because resources such as servers can be used to execute a particular task and after completion, these resources can then be released or reduced.
Some of the examples of cloud computing are Google Slides, Google Drive, Dropbox, OneDrive etc.

________type of website is an interactive website kept constantly updated and relevant to the needs of its customers using a database.
Answer:
Data-driven Website
Explanation:
A Data-driven website is a type of website that is continually updated by its administrators so as to meet users' needs. It is opposed to a static website whose information remains the same and is never changed once uploaded.
The data-driven website is used in a platform where information has to be continually updated. An example is an online platform where people place orders for goods and services. There are usually changing prices and new goods continually uploaded. So, to keep the consumers updated, the administrators of such platforms would use a data-driven platform.

Answer:
"NOT lookup " is the correct approach.
Explanation:
This methodology significantly reduces the quantity of congestion of DNS messages on a certain file. The application establishes that whenever a question reaches if it is processed. Unless the file is loaded, then perhaps the response is returned with the cached cache.Typically the name resolution occurs in something like a DNS File.

All of the following are extra precautions you can take to secure a wireless network EXCEPT ________. change your network name (SSID) enable SSID broadcast turn on security protocols create a passphrase
Answer:
Enable SSID broadcast
Explanation:
All of the following are extra precautions you can take to secure a wireless network except enable SSID broadcast. The correct option is B.
What is SSID broadcast?When people in the area try to join their wireless devices, the name of your network is listed in the list of available networks thanks to broadcasting the SSID.
You can stop SSID broadcasting if you don't want arbitrary wireless devices attempting to connect to your network.
Home networks don't need to have a visible SSID unless they have many access points that devices can switch between.
If your network just has a single router, disabling this function means giving up the ease of adding new home network customers in exchange for certain security gains.
Apart from enabling SSID broadcast, there are other security measures you may take to protect a wireless network.
Thus, the correct option is B.

Raj was concentrating so much while working on his project plan that he was late for a meeting. When he went back to his office, he noticed his system was restarted and his project file was not updated. What advice would you provide Raj in this situation?
Answer:
Explanation:
Depending on the software that Raj was using to create his project he should first see if the software itself saved the project. Usually many software such as those included in the Microsoft Office Suite save the file automatically every 5 minutes or so in case of a power outage or abrupt closure of the file. If this is not the case he should try and do a system restore with the unlikely hope that it restores an older version of his project.
In a situation like this, it would be advisable for Raj to contact IT personnels and seek if the files could be retrieved.
Raj being late for a meeting due to what he was doing meant that the project he was working on is very important. Therefore, to avoid losing thses files, he could contact the IT personnels and request if there is a way to retrieve the project file.These way, the files could be retrieved and avoid losing his work.

Assign decoded_tweet with user_tweet, replacing any occurrence of 'TTYL' with 'talk to you later'.Sample output with input: 'Gotta go. I will TTYL.'Gotta go. I will talk to you later.code given:user_tweet = input()decoded_tweet = ''' Your solution goes here '''print(decoded_tweet)
Answer:
Here is the Python program:
user_tweet = input()
decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')
print(decoded_tweet)
Explanation:
The program works as follows:
Suppose the input is: 'Gotta go. I will TTYL'
This is stored in user_tweet. So
user_tweet = 'Gotta go. I will TTYL'
The statement: user_tweet.replace('TTYL', 'talk to you later') uses replace() method which is used to replace a specified string i.e. TTYL with another specified string i.e. talk to you later in the string stored in user_tweet.
The first argument of this method replace() is the string or phrase that is to be replaced and the second argument is the string or phrase that is to replace that specified string in first argument.
So this new string is assigned to decoded_tweet, after replacing 'TTYL' with 'talk to you later' in user_tweet.
So the print statement print(decoded_tweet) displays that new string.
Hence the output is:
Gotta go. I will talk to you later.
Suppose we have 999 records of employees Emp1, Emp2, Emp5, Emp6 and so on up to Emp998 and Emp999 stored in a sequence. Hence, records are nothing but a row in the table. In the employee table, we want to insert new records Emp3 and Emp4 in the sequence, and once we have done insertion we need to update and retrieve the record efficiently to optimize the performance of a database by minimizing the access time when query is being executed.
You are required to solve the problem with the index sequential access method with pros and cons in the given scenario
The records in the table represents the employee ID of each employee. Assume the table name is EMPLOYEES and the field name of employee IDs is ID, the following SQL query inserts Emp3 and Emp4 into the employees table.
INSERT INTO EMPLOYEES (ID) values (Emp3), (Emp4)
The advantage of using ISAM is that priorities are given to the indices of the records being inserted. So, Emp3 and Emp4 will be inserted immediately after Emp2.
However, a major disadvantage of using ISAM is that it is very expensive to keep the indices in a sequential order;
