Question
For which three reasons was a packet-switched connectionless data communications technology used when developing the Internet? (Choose three.)Group of answer choicesIt can rapidly adapt to the loss of data transmission facilities.It efficiently utilizes the network infrastructure to transfer data.Data packets can travel multiple paths through the network simultaneously.It allows for billing of network use by the amount of time a connection is established.It requires that a data circuit between the source and destination be established before data can be transferred.
Solution
The three reasons why a packet-switched connectionless data communications technology was used when developing the Internet are:
-
It can rapidly adapt to the loss of data transmission facilities: This means that if a particular path in the network fails, the data packets can be quickly rerouted through another path. This makes the network more reliable and robust.
-
It efficiently utilizes the network infrastructure to transfer data: In a packet-switched network, data is broken down into packets and these packets can be routed independently over the network. This allows for efficient use of the network resources as the packets can be routed over less congested paths.
-
Data packets can travel multiple paths through the network simultaneously: This is another advantage of packet-switched networks. Since each packet can take a different path through the network, it allows for load balancing and increased network efficiency. It also increases the reliability of the network as even if one path fails, the packets can be routed through another path.
