Answer:
Transmission Control Protocol (TCP)
Explanation:
FTP: FTP stand for File Transfer Protocol. It is an internet protocol for transferring files between computers on a computer network over TCP/IP connections. It is based on client server architecture in which a client asks for a file and the server (local or remote) sends it. FTP uses TCP to ensure all the data packets are transmitted correctly to the proper destination.
Transmission Control Protocol: It is a protocol used in the Transport Layer of the TCP/IP model. The basic role of this layer is to ensure end-to-end delivery of data from the source to the destination. TCP is a connection oriented protocol that works with the Internet Protocol and provides ordered, guaranteed and error free delivery of data from source to destination. This is how application programs communicate and exchange data through an IP network. It is connection oriented protocol means connection between client and server is setup before data transmission. At source host TCP divides streams of bytes in segments. Then it allocates sequence number to each segment. At destination end it reorders the delivered segments. Then it sends an acknowledgment to sender as a signal that the correct segments have been received. TCP also employs error detection that ensure reliability. TCP also manages flow control and congestion control to avoid data packets loss or delay and to ensure that a sender does not send packets faster than the receiver can receive.

Answer:
B. displaying a list of all available commands within the current mode*
D. determining which option, keyword, or argument is available for the entered command*
Explanation:
Cisco IOS are known for using Command line interface(CLI) that allows execution of certain commands
Cisco system make use devices such as router, switch and others. All these Commans comes with privileged levels that gives access to user that have privilege to access between level 0 and 15.
It should be noted that two functions that are provided to users by the context-sensitive help feature of the Cisco IOS CLI are ;
✓displaying a list of all available commands within the current mode
✓ determining which option, keyword, or argument is available for the
Answer:
The Proper codes in Line a and Line b is given below
average=Sum/3
print (" Average is = ", average)
Explanation:
In the given question it calculated the sum but the program does not calculate the average of the 3 numbers.The average of the 3 number is calculated by using average=Sum/3 statement so we add this code in Line a then After that print the value of average by using the print function so we add this code in Line b.
<u>Output:</u>
f1 in A
f2 in A
f1 in B
f2 in A
f1 in A
f2 in A
f1 in B
f2 in B
<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
