When transmission control protocol (tcp) couples with ip, you get the internet highway traffic controller. Tcp and ip work together to transmit data over the internet but at different levels. Since ip does not guarantee reliable packet delivery over a network, tcp takes charge of making the connection reliable.

A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design. Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications.
A protocol stack is the complete set of protocol layers that work together to provide networking capabilities. Transmission control protocol (tcp) the transmission control protocol is the core protocol of the internet protocol suite. It originated in the network implementation in which it complemented the internet protocol.
The can protocol is a set of rules for transmitting and receiving messages in a network of electronic devices. It defines how data is transferred from one device to another in a network. Interestingly, can was developed with a specific focus on the auto industry but its architecture and advantages have led several other industries (such as the railway, aircraft, and medical sectors) to adopt the protocol as well.
Telnet provides users with a bidirectional interactive text-oriented communication system utilizing a virtual terminal connection over 8 byte. User data is interspersed in-band with telnet control information over the transmission control protocol (tcp). Often, telnet was used on a terminal to execute functions remotely. The user connects to the server by using the telnet protocol, which means entering telnet into a command prompt by following this syntax: telnet hostname port.
Routing information protocol (rip) is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network. It is a distance vector routing protocol which has ad value 120 and works on the application layer of osi model.
Network protocols are formal standards and policies comprised of rules, procedures and formats that define communication between two or more devices over a network. They ensure that computer network devices can transmit and receive data using a common language regardless of their different designs, hardware or infrastructures. Network protocols govern the end-to-end processes of timely, secure and managed data or network communication.

Manual or dynamic association of management in cryptographic keys is done with the help of an ietf-specific key managing protocol named internet key exchange (ike).
The transmission control protocol (tcp) is a transport layer protocol, and the internet protocol (ip) is a network layer protocol. Both protocols were evolved from a earlier packet switching network called arpanet that was funded by the department of defense. The tcp/ip network has been the center of many networking technologies and applications.
It connects the computer to the cabling, which in turn links all of the computers on the network together. Most modern network cards are 10/100 nics and can operate at either 10mbps or 100mbps.

The tcp software in the network protocol stack of the operating system is responsible for establishing and terminating the end-to-end connections as well as transferring data. The tcp software is controlled by the various network applications, such as web browsers or servers, via specific interfaces. Each connection must always be identified by two clearly defined endpoints (client and server).

Computers); appletalk (for macintosh computers), and netbios/netbeui (for lan manager and windows nt networks).
These are: • synchronous protocol these protocol involve timing information of sender along with the data bytes. This protocol helps receiver to remain synchronization with the sender. When the sender has no data to transmit, the sender transmits a sequence of alternating 0s sand 1s to maintain sender/receiver synchronization.
Internet protocol (ip): ip is designed explicitly as addressing protocol. The ip addresses in packets help in routing them through different nodes in a network until it reaches the destination system.
It was originally designed for building automation and control—so things like wireless thermostats and lighting systems often use zigbee.

All of this network data has to be transferred over physical media like copper, fiber optics, and wireless radio. Of the physical layer protocols, ethernet is the most well known. Its popularity in the early days of the internet led us to design other protocols to accommodate its limitations.
The transmission control protocol (tcp) and the user datagram protocol (udp) are used to transmit network data to and from server and client applications. The main difference between the two protocols is that tcp uses a connection-oriented transport, while udp uses a connectionless type of communication. When the tcp protocol is used, a special connection is opened up between two network devices, and the channel remains open to transmit data until it is closed.

Link state routing protocols have a complete picture of the network topology. Hence they know more about the whole network than any distance vector protocol. Three separate tables are created on each link state routing enabled router.
A network protocol is a set of rules followed by the network. Internet protocol suite is the set of communication protocols that implement the protocol stack protocol stack.
Network protocols are a set of rules that govern communication between devices that are connected to a network. These rules are made up of instructions that allow devices to identify and connect to each other, in addition to applying formatting rules, so that messages travel properly from start to finish.

Essentially, tcp/ip describes a protocol which will work on any sort of computer and operating system for transportation of data across the internet between different systems. Invented in the 1970's, largely adopted in the late 1980s, tcp/ip hit its first big problem in the early 1990s when it became apparent that the numbering system was going to run out of numbers in the foreseeable future.
A network of networks is called an internetwork, or simply the internet. The internet hugely connects all wans and it can have connection to lans and home networks. Internet uses tcp/ip protocol suite and uses ip as its addressing protocol.
