Tentxa layer Network ( Connection Oriented and Connectionless Services )

Connection Oriented and Connectionless Services These are the two services given by the layers to layers above them. These services are : Connection Oriented Service Connectionless Services Connection Oriented Services There is a sequence of operation to be followed by the users of connection oriented service. These are : Connection is established Information is sent Connection is released In connection oriented service we have to establish a connection before starting the communication. When connection is established we send the message or the information and then we release the connection. Connection oriented service is more reliable than connectionless service. We can send the message in connection oriented service if there is an error at the receivers end. Example of connection oriented is TCP (Transmission Control Protocol) protocol. Connection Less Services It is similar to the postal services, as it carries the full address where the message (letter) i...

Tentxa Layer Network ( Comparison of OSI Reference Model and TCP/IP Reference Model )

Comparison of OSI Reference Model and TCP/IP Reference Model Following are some major differences between OSI Reference Model and TCP/IP Reference Model, with diagrammatic comparison below. OSI(Open System Interconnection) TCP/IP(Transmission Control Protocol / Internet Protocol) 1. OSI is a generic, protocol independent standard, acting as a communication gateway between the network and end user. 1. TCP/IP model is based on standard protocols around which the Internet has developed. It is a communication protocol, which allows connection of hosts over a network. 2. In OSI model the transport layer guarantees the delivery of packets. 2. In TCP/IP model the transport layer does not guarantees delivery of packets. Still the TCP/IP model is more reliable. 3. Follows vertical approach. 3. Follows horizontal approach. 4. OSI model has a separate Presentation layer and Session layer. 4. TCP/IP does not have a separate Presentation layer or Session layer. 5. OSI is a reference mode...
