How many type of switching in telephony?
Circuit switching and Packet switching are used in Telephony. Circuit switching is used in voice communication and packet switching is used in transmission of data packets to provide internet connection.
A data communication device which provides interface between a data terminating device and a communication link is called as?
packet switching technology which uses short fixed length
What is the definition of ARPANET?
ARPANET stands for Advanced Research Projects Agency Network. ARPA created it during the time of cold war. It was the first packet switching network and was also known as the 'Predecessor of the Global Internet'. Packet Switching has become the leading foundation for both voice and data communication worldwide. Prior to this, data communication was based on circuit switching. A System could use one communication link to communicate with another machine with packet switching.
Which option correctly describes a switching method?
A switching method refers to a technique used in networking to manage data traffic between devices efficiently. It determines how data packets are directed within a network, typically through mechanisms like circuit switching, packet switching, or message switching. Packet switching, for example, breaks data into packets that are routed independently, optimizing bandwidth and reducing latency. Overall, switching methods are crucial for ensuring reliable and efficient communication in various types of networks.
Which switching type will allow the communication devices in the provider network to be shared and only allocated to an individual subscriber during data transfer?
packet-switched
What is package switching?
It is a digital communication network that groups all transmitted data irrespective of content, type or structure into suitable-sized blocks called packets. The principal goal of packet switching is to optimize utilization of available link capacity, minimize response time, and increase robustness of communication.
Data transfer will be faster in circuit switching or packet switching?
Data transfer will be faster in packet switching providing the setup time in circuit switching is greater than the time required to send a packet. If not, that is setup time in circuit switching takes less time, then circuit switching is quicker.
Why packet switching method is used for digital data communication between computers?
Packet switching has two advantages: (1) If something goes wrong, only a small piece of data (the packet) has to be resent. (2) Packet switching allows multiplexing - several communications happening at once.Packet switching has two advantages: (1) If something goes wrong, only a small piece of data (the packet) has to be resent.

What is the difference between data communication and data communication information2010to2013?
The scope of work and the educational requirements are the difference between data communication and data communication information.
What is a data communication link?
data communication link
What four communication methods in a wide area network is needed?
In a wide area network (WAN), four essential communication methods include leased lines, which provide dedicated point-to-point connections; packet switching, which allows data to be sent in packets over shared networks; frame relay, which is a cost-effective method for connecting multiple sites; and MPLS (Multiprotocol Label Switching), which improves the speed and efficiency of data transmission by using labels to direct packets. These methods help ensure reliable, efficient, and scalable data communication across vast distances.
What is the main differences between different switching techniques?
The main difference in different switching techniques are:Circuit switchinginvolves setting up a series of intermediate nodes, in order to propagate the sending node's data to the receiving node. In such a situation, the communication line can be likened to a dedicated communication pipe.In circuit switching a session needs to be established between the PC's for communication which is not in the case of packet based switching, where different packets may take different routes to reach the destination and will be assembled to get the original message.Circuit switching is used in Telephone networks where as packet switching is used in TCP/ IP and the internet.Message switchinginvolves transmitting the message sequentially from one node to another. Each node waits until it has received the entire message before sending it to the next node.Packet switchinginvolves splitting information into data packets, transmitted separately by intermediate nodes and reassembled when they reach the final recipient.It is a new technology and economic than the circuit switching approach. It is usually a connection less service.Rate This Answer
