Application, transport, Internet, and Network Interface.
Answer: Application, transport, Internet, and Network Interface.
TCP/IP
Application: FTP, SMTP, HTTP Transport : TCP, UTP Network : IP, routing protocols Link : PPP ethernet Physical : bit
The protocol stack used on the Internet is the Internet Protocol Suite. It is usuallycalled TCP/IP after two of its most prominent protocols, but there are other protocolsas well. The TCP/IP model is based on a fi ve-layer model for networking. Frombottom (the link) to top (the user application), these are the physical, data link, network,transport, and application layers. Not all layers are completely defi ned by themodel, so these layers are "fi lled in" by external standards and protocols. The layershave names but no numbers, and although sometimes people speak of "Layer 2" or"Layer 3," these are not TCP/IP terms. Terms like these are actually from the OSI ReferenceModel.The TCP/IP stack is open, which means that there are no "secrets" as to how itworks. (There are "open systems" too, but with TCP/IP, the systems do not have to be"open" and often are not.) Two compatible end-system applications can communicateregardless of their underlying architectures, although the connections between layersare not defi ned.The term "protocol stack" is often used synonymously with "protocol suite" as animplementation of a reference model. However, the term "protocol suite" properlyrefers to a collection of all the protocols that can make up a layer in the referencemodel. The Internet protocol suite is an example of the Internet or TCP/IP referencemodel protocols, and a TCP/IP protocol stack implements one or more ofthese protocols at each layer.
Because it tests connectivity at Layers 3, 2, and 1 of the OSI model.
Data is sent around the internet in protocol stacks. This is built into the computer's operating system. The protocol stack translates the message from alphabetic text, into electronic signals transmitted over t he internet, and back to alphabetic text.
- In your own words, define the term 'protocol' and what is the difference between protocol and protocol suite
Open System Interconnection (OSI) reference model, Consists of seven layers
The IP stack, also known as the Internet Protocol Suite, is a set of networking protocols that govern how data is transmitted over the internet. It is commonly organized into four layers: the application layer, transport layer, internet layer, and link layer. Each layer has its own specific functions and protocols, such as TCP and UDP at the transport layer and IP at the internet layer, enabling communication between devices across diverse networks. This layered architecture helps manage the complexities of data transmission and ensures interoperability among various network technologies.
The Internet protocol stack, often referred to as the TCP/IP model, consists of five layers: the application layer, transport layer, internet layer, link layer, and physical layer. The application layer handles high-level protocols and user interfaces, while the transport layer ensures reliable data transfer between hosts. The internet layer is responsible for routing packets across networks, and the link layer manages the physical transmission of data over network interfaces. The physical layer deals with the actual hardware and transmission mediums used to transmit data.
