Answer
Procedural programming, Object-oriented programming
Explanation
Procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures  within its development period of time. It contains a systematic order of statements, functions and commands to complete a computational task or program. It is centered on creating procedures. While object oriented programming  is a programming language that is centered on creating objects rather that actions and data rather than logic.. It has four principles which are inheritance, polymorphism, abstraction and Encapsulation
 
        
             
        
        
        
TCP tells or state how applications can make channels of communication across a network.
<h3>What is the role of TCP?</h3>
TCP is known to often help in the management of how a message is put together into smaller packets before they are sent or transmitted over the internet and then put together again in the right way at the arriving or destination address.
Therefore, TCP tells or state how applications can make channels of communication across a network.

Over a TCP connection, suppose host A sends two segments to host B, host B sends an acknowledgement for each segment, the first acknowledgement is lost, but the second acknowledgement arrives before the timer for the first segment expires is True.
True
<u>Explanation:</u>
In network packet loss is considered as connectivity loss. In this scenario host A send two segment to host B and acknowledgement from host B Is awaiting at host A. 
Since first acknowledgement is lost it is marked as packet lost. Since in network packet waiting for acknowledgement is keep continues process and waiting or trying to accept acknowledgement for certain period of time, once period limits cross then it is declared as packet loss. 
Meanwhile second comes acknowledged is success. For end user assumes second segments comes first before first segment. But any how first segment expires.
