File transfer protocol
routing info protocol
It stands for Internet Protocol. It is basically your mailing address for your computer. When you use the internet you send and receive "packets" of data called datagrams. Your IP (Internet Protocol) is what allows you to be identified in the system and receive these packets.
A ping command is used to check whether the host is alive or not. A ping command is used when you want to check if the host can send or receive packets. The protocol that is responsible for Ping command is ICMP.
The basic protocol that allows all computers to interact on the internet is TCP/IP.
TCP/IP networking protocol is used when communicate through the internet
In the United States of America, Rob Kahn (from New York) and Vint Cerf (from Connecticut) together invented the (TCP) Transmission Control Protocol in 1972-1973. They wrote "A Protocol for Packet Network Intercommunication", TCP/IP protocol is what is used to send information over the internet.
packet switching
Simple Mail Transfer Protocol, is the technology used to send out email messages. It goes hand in hand with POP (Post Office Protocol) that is, typically, employed for receiving emails from a web server to an email program or an email client.

Meaning: Protocol is nothing but set of rules and regulations desingned to communicate between systems on the network.Used on the Internet: The protocols are used on the internet to transfer the data from one place to another. It used to send the secure information around network connections.
TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. For example, when an HTML file is sent to you from a Web server, the Transmission Control Protocol (TCP) program layer in that server divides the file into one or more packets, numbers the packets, and then forwards them individually to the IP program layer. Although each packet has the same destination IP address, it may get routed differently through the network. At the other end (the client program in your computer), TCP reassembles the individual packets and waits until they have arrived to forward them to you as a single file. TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end. In the Open Systems Interconnection (OSI) communication model, TCP is in layer 4, the Transport Layer. *This answer was taken from http://searchnetworking.techtarget.com/definition/TCP
Internet was first used by Charley Kline at UCLA to send the first packets over ARPANet to connect with a computer at Stanford Research Center in 1969. The system crashed. The early internet was used by computer experts, engineers, scientists, and librarians.
Routing protocol is used to dynamically learn routing information so routers know where to send packets. The only other option is to manually define all routers within a network which would be very impractical.
