In packet switching, packets can take the quickest route between nodes and arrive independently of when other packets in their data stream arrive.
network + guide to networks Chapter 5 Review Question 7
The basis of a Packet Switched Network is the Packet Switch. This network enables the service user to connect to any number of hosts via a local POTS dial-up/port. The various hosts pay to be connected to this type of network, and that's why there is often a surcharge for connection to larger public services like Compuserve or The Source. A Packet Switched Network provides efficient data transfer and lower rates than normal circuit switched calls, which can be a great convenience if you are planning to do a lot of transferring of files between you and the host. Not only is the communication efficient, it is virtually error free. Whereas in normal circuit switched calls, there could be a drastic increase in errors, thus creating a bad transfer of data. When using a Packet Switched Network, it is not important that you communicate at the same baud rate as your host. A special device regulates the speed so that the individual packets are sped up or slowed down, according to your equipment. Such a device is called a PAD (Packet Assembler Disassembler). A PSN also provides access to a variety of information and news retrieval services. The user pays nothing for these calls, because the connections are collect. Although the user may have to subscribe to the service to take advantage of it's services, the connection is usually free, except for a surcharge on some of the larger subscription services.
Circuit switching has the following advantages
Reliable
Low latency which makes it faster with low error
Circuit switching also has a guaranteed link with a reserved bandwidth between hosts. With circuit switching once the connection is established it can be accessed whenever needed. Versus with packet switching where resources are used on demand and can only transmit when it has access to the connection link.
In telecommunications, a circuit switching network is one that establishes a circuit (or channel) between nodes and terminals before the users may communicate, as if the nodes were physically connected with an electrical circuit.
Packet switching is a digital network communications method that groups all transmitted data, irrespective of content, type, or structure into suitably-sized blocks, called pubes. The network over which packets are transmitted is a shared network which routes each packet independently from all others and allocates transmission resources as needed. The principal goals of packet switching are to optimize utilization of available link capacity, minimise response times and increase the robustness of communication. When traversing network adapters, switches and other network nodes, packets are buffered and queued, resulting in variable delay and throughput, depending on the traffic load in the network.
The advantage to circuit switching is that it is a dedicated circuit. Packet switching has to share the resource with other users and packets.
Packet switching has to distinct advantages.
1. A damaged packet can be resent - only the damaged part is sent, no need to resent an entire file.
2. It allows multiplexing; different users, or different processes from the same user, can communicate at the same time.
Packet-switched networks can efficiently use multiple routes inside a service provider network.

Technology has opened new doors to people. Without technology there would be no computers, cars, wikianswers :P or anything that would make the world what it is today. Disadvatages of technology would be that every day alot of green house gasses are being produced from factories all over the world. but if we increase our knowledge and technological powers we will some day be able to power factories and such without the use of bad fuels
i don't think there can be an advantage but one of these is it help as more inventions are taking place and technology is developing. shama age 12
The answer can be benefits to communication, improved workplace efficiency, competitive advantage over rivals, cost reduction, and economic efficiencies. Allsoftgo
Technology did not affect the outcome. As the war progressed new technological inventions were used, like chemical weapons, used the first time by Germany in 1915. But both sides progressed at the same rate, no one had an advantage over the other in technology.
The main advantage of using a Motorola cable modem over one from another manufacturer is that is was designed to meet the standards of next generation technology. It is compatible with a wide range of operating systems and always stays connected.
