Answer:
strcmp(char * A, char * B);
strcat(char * A, char * B)
Explanation:
One of these basic functions is the function strcmp(char * A, char * B).
This functions compares if two strings are equal; If they are, it returns 0. If not, it returns 1;
So, an example:
char A[13] = "Buffalo Bills";
char B[13] = "Buffalo Bills";
if (strcmp(A,B) == 0)
 printf("The strings are the same\n);
else
printf("The strings are not the same");
In this case, they are the same.
----------------------
If for example:
char B[13] = "Buffalo Billz"
It would fall in the else, A and B would not be the same strings.
--------------------------
Other function is the strcat(char * A, char * B); 
This function takes two strings as an input, and concatenate them to the first.
For example:
char A[15] = "Buffalo";
char B[5] = "Bills";
strcat(A, B);
printf("%s\n", A);
The output is: 
Buffalo Bills
 
        
             
        
        
        
Different types of connections are..
-A network is two or more devices connected through links.
-There are two possible types of connections: point-to-point and multipoint.
-A point-to-point connection provides a dedicated link between two devices.
Explain the different types of topologies 
-Star network…
In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication.
-Ring network…
A number of repeaters are used for Ring topology with large number of nodes, because if someone wants to send some data to the last node in the ring topology
-Bus network…
In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop 
-tree topology…
Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology. This topology integrates

Different type of networks
-Computer network…
Virtual Private Network (VPN). By extending a private network across the Internet, a VPN lets its users send and receive data.
-LAN…
Using routers, LANs can connect to wide area networks (WANs, explained below) to rapidly and safely transfer data. 3. Wireless Local Area Network (WLAN).
-Wide area network…
Wide area network, or WAN. In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files etc.
-Metropolitan area network…
MAN or Metropolitan area Network covers a larger area than that of a LAN and smaller area as compared to WAN. It connects two or more computers that are apart.
-Wireless LAN…
WLAN (Wireless Local Area Network) helps you to link single or multiple devices using wireless communication within a limited area like home, school, or office 
-Wireless network…
A Wireless Local Area Network or WLAN is a network that is used to connect different devices without using wires etc.
-Storage area network…
Storage Area Network is a type of network which allows consolidated, block-level data storage. It is mainly used to make storage last longer etc.
-Personal area network…
PAN can be used for establishing communication among these personal devices for connecting to a digital network and the internet. 
-Campus area network…
A Metropolitan Area Network or MAN is consisting of a computer network across an entire city, college campus, or a small region. This type of network is large.
Explain your own understand about protocol and standards
A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

Explain layers in tcp/ip model
Four layers of TCP/IP model are 1) Application Layer 2) Transport Layer 3) Internet Layer 4) Network Interface. ... It is also known as a network layer. Transport layer builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system.
what are the peer to peer processing
In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data
