Connection-Oriented Protocols:

Connection-Oriented Protocols:

The principally important characteristic of a connection oriented protocols is to facilitate a logical connection exist and recognized among two devices ahead of transferring a stream of data. Connection-oriented protocol might be present apply in the data link layers of the protocol stack or in the transport layers of the protocol stack, depending lying on the physical connections within place and the services essential via the system so as to be communicating.

Normally the achievements by subsequent a particular set of regulations that point out how a connection must be begin, talk, administer and terminated. Frequently it started with one host or device commences by sending a request to start a connection, and the other host or devices willpower respond. These hosts or devices resolve set the standard control information towards consent lying on and how the connection should be set up. If this is satisfying and victorious, data is sent between the hosts or devices. When it is done, the link willpower terminated.

Example of a connection-oriented protocol at the transport layer is the TCP protocol.

The communication sitting can be a circuit switched connection, or a virtual circuit connection within a packet switched network. For example the transport layer is the TCP protocol.

Simplex, Half-Duplex and Full Duplex Operation

Simplex, Half-Duplex and Full Duplex Operation


Simplex – The signal be sent away in unidirectional mode. This indicate the signal is sent away form the resource to the destination merely. The signal movements in single direction only. E.g. television or radio transmission.

Half-Duplex - Contrast to simplex communication, half duplex message authorized the traffic to travel in mutually directions. Half duplex merely approved the signal to pass through both direction but at the same time. This way that the signal have to be sent out first and finish the session as of a place and then simply the reception signal be able to be sent in and the session end from a station. Half duplex only authorized an only signal stream in one method or direction at an instant.

Full-Duplex transmission – It be able to function or effort in two-way course at a similar time. For the reason that of this, proficient full duplex enlarge the act of the networks. It can be sent and receive at the same without any problem. Full Duplex make use of two couple of wires where permit the station to transmit and obtain signal at any occasion. Full Duplex authorized he signal stream in mutually direction at the same time.

MAC addressing

MAC addressing short form of Media Access Control address. MAC provide the physical or devices or hardware address. MAC provide adrress on the network interface card (NIC), which located int the Layer 2 addresses. MAC address is very unique . The usual MAC addressing format is

XX:XX:XX:YY:YY:YY

Note ; XX:XX:XX = ID number of the adapter manufacture and

YY:YY:YY = serial number of manufacture. MAC address usually used the hexadecimal numbering format.
