TCP/IP
Internet Protocol version 4 ( IPv4 ) is the fourth version in the development of the Internet Protocol (IP) and the first version of the protocol to be widely deployed. Together with IPv6 , it is at the core of standards-based internetworking methods of the Internet . IPv4 is still used to route most traffic across the Internet. [ 1 ] IPv4 is described in IETF publication RFC 791 (September 1981), replacing an earlier definition ( RFC 760 , January 1980). IPv4 is a connectionless protocol for use on packet-switched Link Layer networks (e.g., Ethernet ).

Host (network)
A network host is a computer connected to a computer network . A network host may offer information resources, services, and applications to users or other nodes on the network. A network host is a network node that is assigned a network layer host address . Computers participating in networks that use the Internet Protocol Suite may also be called IP hosts.Internet Protocol version 6 ( IPv6 ) is the latest revision of the Internet Protocol (IP), the communications protocol that routes traffic across the Internet . It is intended to replace IPv4 , which still carries the vast majority of Internet traffic as of 2013. [ 1 ] IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion . Every device on the Internet, such as a computer or mobile telephone, must be assigned an IP address for identification and location addressing in order to communicate with other devices. With the ever-increasing number of new devices being connected to the Internet, the need arose for more addresses than IPv4 is able to accommodate. IPv6 uses a 128- bit address, allowing 2 128 , or approximately 3.4 × 10 38 addresses, or more than 7.9 × 10 28 times as many as IPv4, which uses 32-bit addresses. IPv4 allows only approximately 4.3 billion addresses.

The Internet protocol suite is the set of communications protocols used for the Internet and similar networks, and generally the most popular protocol stack for wide area networks . It is commonly known as TCP/IP , because of its most important protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP), which were the first networking protocols defined in this standard. It is occasionally known as the DoD model due to the foundational influence of the ARPANET in the 1970s (operated by DARPA , an agency of the United States Department of Defense ). TCP/IP provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination.

Dynamic Host Configuration Protocol
A DHCP Server settings tab The Dynamic Host Configuration Protocol ( DHCP ) is a network protocol used to configure devices that are connected to a network (known as hosts ) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model . In a typical personal home local area network (LAN), the server is a router [ 1 ] while the clients are personal computers, smart phones, or printers.
Network switch
A network switch is a computer networking device that links network segments or network devices . The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model . Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches . Switches exist for various types of networks including Fibre Channel , Asynchronous Transfer Mode , InfiniBand , Ethernet and others. The first Ethernet switch was introduced by Kalpana in 1990.
