P2P Networks

AJITH KP   March 31, 2013

   A P2P[Peer 2 Peer]computer network is one in which each computer in the network can act as a server or client for the other computers connected in the network. It does not want a dedicated server to transfer data to clients. Every nodes connected to the server acts as both clients and servers, so the transfer rate of data will be greater compared to Client/Server network. P2P is designed suitable to small and medium LANs. The advantages of Peer 2 Peer network are, there is no centralized server for files and applications, no need of dedicated servers, also the nodes are independent to each other, so the failure of any nodes will not affect the communication(mostly P2P is used for file transfer). The disadvantage of P2P network is lack of security.

   The most familiar  P2P network is BitTorrent. BitTorrent is one of the most popular P2P file sharing network.

Computer Networks

AJITH KP   March 30, 2013

   According to Wikipedia, "A computer network, or simply a network is a collection of computers and network hardware interconnected by communication channels that allow sharing of resources and information."

   The "Computer Network" is a collection of autonomous computers interconnected by communication channels. Two or more computers are said to be interconnected if they are able to communicate each other. The communication channel may be optical fiber, copper wire, microwaves, satellites or any medium that allows communication. The networks may be in different shapes(Topology: Bus Topology, Ring Topology, Star Topology, Tree Topology, Mesh Topology), sizes(LAN, WAN, SAN, DAN, CAN), and forms.

   The Internet is known as Network of Networks. Internet is a global system of interconnected computer networks that use the standard Internet Protocol suit(TCP/IP).

   This is the basic knowledge of Computer Networks. We can discuss deep information about computer networks later.

Hi guYz,
   before few months I have posted the same post with another logic here.
Now I would like to give another logic to check the same thing. It is using the in-built function of header file string.h. The function name is strrev.

/* * Program to check Palindrome words... */ #include <stdio.h> #include <string.h> void main() { char str[20], strv[20]; printf("Input a String: "); scanf("%s", str); strcpy(strv, str); strrev(strv); if(strcmp(strv, str)==0) { printf("%s is Palindrome"); } else { printf("%s is not Palindrome"); } getch(); }
