what is the difference between connection oriented and connectionless protocol?

Connection oriented protocol makes a connection and checks whether message is received or not and sends again if an error occurs, while connectionless service protocol does not guarantees a message delivery. ... Connection oriented service interface is stream based and connectionless is message based.

Classless addressing uses a two-part view of IP addresses, and classful addressing has a three-part view. ... With classless addressing, the network and subnet parts from the classful view are combined into a single part, often called the subnet or prefix, with the address ending in the host part.

In a transparent connection, the client is unaware of the firewall. In a non-transparent proxy connection, the client (e.g., a Web browser) sends all requests to the firewall. The client's connections settings explicitly specify that all requests be sent to the firewall as a proxy.

The basic difference between network layer and transport layer is that transport layer protocol provides logical communication between processes running on different hosts , whereas network layer protocol provides logical communication between hosts.

TCP provides a connection-oriented service over packet switched networks. Connection-oriented implies that there is a virtual connection between two endpoints. There are three phases in any virtual connection. These are the connection establishment, data transfer and connection termination phases.

KEY DIFFERENCE OSI has 7 layers whereas TCP/IP has 4 layers. The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. ... OSI refers to Open Systems Interconnection whereas TCP/IP refers to Transmission Control Protocol.

TCP is a connection-oriented protocol and UDP is a connection-less protocol. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.

Bit-oriented protocols transmit information without regard to character boundaries and thus handle all types of information images. Bit-oriented protocols are much less overhead-intensive, as compared to byte-oriented protocols, also known as character-oriented protocols.

SSH always uses TCP as it is connection-oriented, whereas UDP is connectionless (refers to network protocols that a host can send a message without establishing a connection in hopes that the message will reach its destination.)

Non-Persistent Connection: It requires connection setup again and again for each object to send. Persistent connection: It does not require connection setup again and again. Multiple objects can use connection.

In Stateless, server is not needed to keep the server information or session details to itself. In stateful, a server is required to maintain the current state and session information. In stateless, server and client are loosely coupled and can act independently. In stateful, server and client are tightly bound.

Connection oriented protocol makes a connection and checks whether message is received or not and sends again if an error occurs, while connectionless service protocol does not guarantees a message delivery. Connection oriented service is more reliable than connectionless service.

2 Answers. ICMP is a control protocol, meaning that it designed to not carry application data, but rather information about the status of the network itself. ... UDP, on the other hand, is a connection-less protocol. Communication is datagram oriented, so the integrity is guaranteed only on the single datagram.

Unlike TCP, UDP doesn't establish a connection before sending data, it just sends. Because of this, UDP is called "Connectionless". UDP packets are often called "Datagrams". ... DNS servers send and receive DNS requests using UDP.

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. The speed for TCP is slower while the speed of UDP is faster. ... TCP does error checking and also makes error recovery, on the other hand, UDP performs error checking, but it discards erroneous packets.

A nonpersistent connection is the one that is closed after the server sends the requested object to the client. ... With persistent connections, the server leaves the TCP connection open after sending responses and hence the subsequent requests and responses between the same client and server can be sent.
