The importance of packet switching is that it is more economical than using private lines, especially if the amount of traffic between the two terminals does not require a dedicated circuit. Packet switching is also more economical than data when the data communication sessions are shorter than the minimum time for a chargeable call. Packet switching is the technique of sending data in small chunks called packets.Continue Reading
With packet switching, each packet contains destination information, thereby making it easier to send many messages quickly to various destinations. The delivery rate of the messages depends on the speed at which the data terminal equipment can transmit packets. Computers allow dynamic routing at each node.
Packet data has maximum efficiency and throughput because the network always picks the best possible route for a packet to take at any given time. Additionally, the network has an inherent intelligence that allows for graceful degradation of the network if a link or node fails. Although automatic rerouting of packets around a failed area causes congestion, it does not affect the normal functioning of the overall system. The network intelligence also identifies and corrects errors, diagnoses faults, verifies message delivery and checks reverse billing, among other important functions.Learn more about Internet & Networking
A packet sniffer is a network tool used by technicians to identify and analyze problems with the network. A packet sniffer can also be utilized by hackers to mine data, such as identity information. Packet sniffers come in both hardware and software forms.Full Answer >
Although both gateways and routers are a part of the process of regulating traffic between two networks, they are different from one another: gateways regulate traffic between two different types of networks, while routers regulate traffic between two similar networks. Even though gateways and routers perform similar functions, this difference means that they are used in different settings and for different reasons.Full Answer >
A DDoS attack is an attempt to make a website or web service unavailable by flooding the server with traffic and data. DDoS is an abbreviation for Distributed Denial of Service. DDoS attacks cause one out of three "downtime incidents," according to Digital Attack Map.Full Answer >
