Typically the OSI model is used, but the older TCP/IP model is also popular.
SNMP
The most commonly used network protocol is Internet Protocol (IP), this is the protocol used within the Internet, this protocol is a derivative of TCP/IP Transmission Control Protocol/Internet Protocol. This is used in 99% of common corporate networks, the TCP components deals with efficiencies of network transmission. TCP/IP or IP overlays the common Ethernet networking topology.
The main communication or network protocol is the TCP/IP protocol. (Transmission Control Protocol/Internet Protocol)
What is a Network, Alex? *to have a network, you will also need a common communication protocol.
A protocol is a set of rules for communication.A protocol is a set of rules for communication.A protocol is a set of rules for communication.A protocol is a set of rules for communication.
network
Is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself; it relies on an encryption protocol that it passes within the tunnel to provide privacy. It's also carry common protocol to encapsulation process Point - to - point (PPP). L2TP does not provide confidentiality or strong authentication by itself. L2TP requires that the ISP's routers support the protocol. The L2TP protocol is primarily used to integrate multi-protocol dial-up services into an existing ISP point of presence. The protocol is commonly used for reselling ADSL endpoint and cable network connectivity by sitting between the end-user and the ISP. As a result, the reselling cable provider does not appear to be the one doing the transport.
Local Area Network A data network that does not include routing to remote locations. The most common protocol for wired LAN is currently Ethernet. The most common cabling for wired LAN is currently UTP (unshielded twisted pair) copper.
SMT (Simple Mail Transfer), POP3, or even plain HTML
Because the internet is not homogeneous. Some segments of the internet are ethernet, some are SONET, ect. Some datalink layer protocols are more suited for one application than another. What links all these segments is the Network protocol. The network protocol used on the internet is IP.
The most popular connectors found these days on the ends of network cables are commonly called RJ45 connectors.
You need protocols in computer networks because computer networks consist of devices and software made by many different vendors. The only way to ensure compatibility among them all is to have common documents (i.e. the protocol specifications) that describe the mechanics and formats of all the data exchanged over the network.
