Why TCP IP is more reliable?

Unlike UDP, TCP provides reliable message delivery. TCP ensures that data is not damaged, lost, duplicated, or delivered out of order to a receiving process. TCP achieves this reliability by assigning a sequence number to each octet it transmits and requiring a positive acknowledgment (ACK) from the receiving TCP.

Which model is widely used TCP IP or OSI?

The last two layers of the OSI model map to the network layer of the TCP/IP model. TCP/IP is the most widely used model as compared to the OSI model for providing communication between computers over the internet.

What is the difference between OSI and TCP IP?

OSI refers to Open Systems Interconnection whereas TCP/IP refers to Transmission Control Protocol. OSI follows a vertical approach whereas TCP/IP follows a horizontal approach. OSI model, the transport layer, is only connection-oriented whereas the TCP/IP model is both connection-oriented and connectionless.

Why do we still use the OSI model?

For decades, the OSI model has been used to help IT professionals understand networking and resolve problems that might occur at any point during the networking process. As a result, it’s still useful for infosec professionals conducting asset inventories today.

What is difference between OSI and TCP IP?

What is OSI TCP IP?

OSI represents Open System Interconnection. TCP/IP model represents the Transmission Control Protocol / Internet Protocol. OSI is a generic, protocol independent standard. It is acting as an interaction gateway between the network and the final-user. The protocols were created first and then built the TCP/IP model.

What are the similarities between TCP IP and OSI?

Similarities between the TCP/IP model and the OSI model Both are logical models. Both define standards for networking. Both provide a framework for creating and implementing networking standards and devices. Both divide the network communication process into layers.

What is the disadvantage of OSI model?

The disadvantages of the OSI model are It is purely a theoretical model that does not consider the availability of appropriate technology. This restricts its practical implementation. The launching timing of this model was inappropriate. When OSI appeared, the TCP/IP protocols were already implemented.
