What is message switching?
Messaging is a method of transmission of telecommunications data, which was first introduced in 1961; Unlike switching packets that came after, switching messages sends the entire message as one unit. For the transfer of the message, the message is first stored and then transferred by hops until it reaches the target. Most messages are too large for random access memory (RAM), so messages are temporarily stored on a hard drive. While switching messages is not a primary data transmission method, because it is slower and experienced delay, it is still used to send e -mail. The advantage of this method is lower band width costs, better network overload management and easy transfer of messages to different goals. After saving, the message is sent to a router that switches it to the first hop or node. With each hop, the message is checked in terms of problems or errors before sending to the next hop. The message is constantly jumping until it reaches its final goal.
When switching packets, the message turns into small packets that are sent immediately, but switches the message as the whole unit. Sending the entire unit takes up more memory. In order to prevent the computer from slowing down, these messages are stored on a hard disk, unlike switching packets that hold packets in RAM. Most users do not even realize that the message is stored temporarily because it takes only a few seconds or minutes to send the message.
Message switching is a slower form of data transfer, but is often used to e -mail. E -Maily are usually longer than bits packets, so it allows users to create more e -Maily than if the package was used to switch ET. This data transmission method can also be used for low -priority reports to save the bandwidth for high priority messages.
Although it is older and slower than switching packets, switching of messages has certain advantages. Because it's slowerAnd messages can be stored in nodes, these messages can easily slip through nets with heavy overload. This method is also better to send a message to several people at the same time and overall uses a smaller bandwidth.
