消息和数据包交换之间的区别

1.消息切换：
在这种技术中，整个消息从一个节点到另一个节点的传输没有中断。它首先存储然后转发需要更多时间的信息。因此，增加了访问时间。在发送方和接收方之间不存在直接链接。

2.分组交换：
在数据包交换中，信息以数据包的形式在发送方和接收方之间传输。这些数据包从发送方一路转发到接收方。每个数据包都与一个报头相关联。然后，这些数据包然后重新组合为原始消息。由于减少了访问数据包所需的时间，因此提高了性能。因此，网络的整体性能得以提高。

消息和分组交换之间的区别：

Message Switching	Packet Switching
A complete message is passed across a network.	Message is broken into smaller units known as Packets.
In this, computer language used is ASCII, baudot, morse.	In packet switching, binary type is used.
In message switching there is no limit on block size.	Packet switching places a tight upper limit on block size.
Message exist only in one location in the network.	Parts i.e. packets of the message exist in many places in the network.
Example: Hop-by-hop Telex forwarding and UUCP(UNIX-to-UNIX Copy Protocol)	Example: Frame Relay, IP, and X. 25
Physical links are allocated dynamically.	Virtual links are made simultaneously.
Access time is reduced due to increase in performance as packets are stored in disk.	Packets are stored in main memory.
