While in Delhi, I suggest you must take a walking tour of Old Delhi. You can do Google search, but one the the best suggested tour is 'masterjikeehaveli'. Report inappropriate content.
The Internet protocol suite is the conceptual model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP because the original protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
TCP/IP layers: TCP/IP is a two-layer protocol. The upper layer-Transmission Control Protocol-assembles a message or file into smaller packets transmitted over the Internet and received by a TCP layer that reassembles these packets into their originals.CP/IP uses client/server communication model. In this model a computer user (client) requests a service (sending a webpage) and is provided with it by another computer (server) on the network. We all know even higher layer application protocols that use TCP/IP to get to the Internet.
