TCP is known to be a type of a connection-oriented protocol, while UDP is a connectionless protocol. TCP and UDP provide data transport between hosts.
- TCP and UDP are known for their speed, as TCP is slower and can retransmit lost data packets than UDP. UDP is said to be faster, simpler, and efficient protocol.
Data transport is simply known to be an the energy problem. It is the amount of energy needed to transport a bit from the closest neighbor.
Data Transport Service gives  a reliable connection for moving large amounts of data at very fast speeds.

Answer:
"64" is the output of the above code.
Explanation:
- The function holds the expression with (**) operator which is used to calculate the power in python language.
- So if we write 2**4, then this will give 16 as output. It is because when we calculate the  , then it will become 16. , then it will become 16.
- The above question passes the num1 and num2 value in the function as an argument which is 3 and 4.
- So 3 will be initialized for x variable and 4 is for y variable.
- So when we calculate  then it will become then it will become which will become 16. which will become 16.
- So 64 is the output for the above question.
 
        
             
        
        
        
Answer:
Tech B is correct.
Explanation:
First, It is international best practice never to exceed the lifting capacity of any hoist. To do so would expose those involved to risks that may prove to be fatal.
Second, research has shown that gasoline vapors, as well as vapor from almost all other flammable or ignitable liquids or substances, are heavier than air.
More specifically, Gasoline produces flammable vapors that are heavier than air by 3 to 4 times. This means they can travel for great distances along the ground. Worst still, inspection pits are must be kept free from gas vapors because they tend to accumulate in low or enclosed spaces.
Both technicians should and must observe all occupational, health, and safety rules and guidelines stipulated and required for their industry/practice.

Answer:
a. social engineering attack
Explanation:
Two-factor authentication requires that the user/owner of the account enter a second verification code alongside their password in order to access the account. This code is usually sent to a personal phone number or email address. Therefore in order to breach such a security measure the best options is a social engineering attack. These are attacks that are accomplished through human interactions, using psychological manipulation in order to trick the victim into making a mistake or giving away that private information such as the verification code or access to the private email.
