Define the terms packet datagram frame and token?

Data is transmitted on a network in pieces called packets, datagrams, or frames. Specifically, the frame is the header and trailer surrounding the data. The entire header, trailer, and data is called the packet or datagram. A token is a small packet used on Token Ring or FDDI networks. The token is passed from node to node to indicate to the node that data can be sent on the network.


What is the difference between datagram and packet?

datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp


What is datagram packet?

Clients and servers that communicate via a perfect channel have a dedicated point-to-point channel between themselves (or at least the illusion of one). To communicate, they must first establish the connection, transmit the data, and then close down the connection. All data sent over the channel is received in the same order that it was sent. This is guaranteed by the channel. In contrast, clients and servers that communicate via datagrams send and receive completely independent packets. These clients and servers do not have a dedicated point-to-point channel. Rather the packets are sent on their way over the network on whatever route is available.A packet sent over a perfect channel does not contain any information about its source or its destination. The channel contains that information. In contrast, a datagram packet must contain the complete address of its source or destination (depending on if the datagram is sent or received).Definition: A datagram is an independent, self-contained message sent over the network whose arrival, arrival time, and content are not guaranteed.The java.net package contains two classes to help you write Java programs that use the datagram model to send and receive packets over the network: DatagramSocket and DatagramPacket. A DatagramSocket is a communcation link used to send datagrams between applications. A DatagramPacket is a message sent between applications via a DatagramSocket.


What three packets are exchanged between two hosts when establishing a tcp connection?

The SYN packet, the SYN ACK packet , And ACK packet


How does the network layer in a connection-oriented packet-switching network differ from the network layer in a connectionless packet switching network?

An upper-layer packet is split into 10 frames, each of which has an 80 percent chance of arriving undamaged. If no error control is done by the data link protocol, how many times must the message be sent on average to get the entire thing through? An connection-oriented service (like TCP) does error checking and requests data to be resend. The packet has several options for error free transport. Connectionless service (think UDP) does not check for undamaged arival. It has a much smaller packet size and is also faster.

Datagram packet and datagramsocket explain the functions of datagram packet and datagramsocket?

A datagram or packet needs to be self-contained without reliance on earlier exchanges because there is no connection of fixed duration between the two communicating points as there is, for example, in most voice telephone conversations.


How does IP layer keep the packets from getting misplaced or collected out of orders?

The IP adds a header of control information to each segment recieved from the TCP in order to form the IP datagram or IP packet. The data can be fragmented to smaller packets if necessary.


What packet exceeds the medium's maximum packet size?

Giant packets. Runt packets are packets that are too small. Giant packets are too large for the medium.

Advantages and disadvantages of datagram packet switching?

A packet sniffer can also be used on the Internet to capture data traveling between computers. Internet packets often have very long distances to travel, passing through several routers that act like intermediate post offices. A packet sniffer might be installed at any point along the way. It could also be clandestinely installed on a server that acts as a gateway or collects vital personal information.A packet sniffer is not just a hacker's tool. It can be used for network troubleshooting and other useful purposes. However, in the wrong hands, a packet sniffer can capture sensitive personal information that can lead to invasion of privacy, identity theft, and other serious eventualities.
