The short answer is "no." The longer answer is that "packet switching" is the way the internet works. If you send a very short message, it might end up as a single "packet." A packet consists of a sandwich that contains your message as the filling. The beginning contains routing information - where you want the message to go, and eventually where the message has been (how many stops it made along the way and what their address is). The end contains information to keep the message "clean" and be sure we don't drop some words or letters, or add some.
If your message is long, it will probably be divided into several packets, and each packet is identified with a unique message identifier showing it is your message in a number of pieces and a sequence within the message. Each packet is then sent out over the internet. Each packet will probably follow a different route through the internet, stopping at different places along the way to the destination. At the destination, the receiving machine will recognize that a packet is part of a bigger message, and store it until all the parts are received. It will then assemble it as a single message and pass it on to your application, usually your internet browser such as Internet Explorer or Firefox.
So...a line is more efficient when you fill it with large blocks of data. When you use packets you are duplicating a lot of information in each packet, and generating information to identify the packet and the data within it. Therefore, packets are inherently NOT effiicient for line usage. However...They are extremely effective in allowing the internet to get large amounts of data to/from places in a short amount of time by being able to process all your packets in "parallel" mode. So if your message takes 6 packets, those 6 packets can be sent from point A to point B through 6 different routes using a lot of different machines along the way. The message gets to you quicker than sending it all at once, which is line efficient but not network efficient. By the way, you may have heard the term "packet loss." You can now figure out that that means one of the packet's in a message never made it to the receiving machine. When the receiving machine receives a packet for a message, it starts a clock on that message. If it doesn't receive the rest of the packets in a reasonable amount of time, it flags the message as incomplete and logs the packet loss. You now know a bit of how the internet works.

Difference between packet switching and message switching by table format?
In Packet switching the packetss are stored and forwarded from primary storage (RAM) while in Message switching the message are stored and relayed from seconadary storage (disk). In Packet switched network data are transmitted in discrete units of potentially variable length blocks called packets, while in Message switching mecahnism a node recives a message stores it until the apporiarate route is free, then sends it along. Message switching sends data units that can be of any length. Packetswitching has a maximum packet size. Any message longer than that is splitup into multiple packets.
When was Black Ball Line - trans-Atlantic packet - created?
Black Ball Line - trans-Atlantic packet - was created in 1817.
What is call switching and line switching?
Line switching, also referred to as circuit switching, is how landline phone systems connect. This method uses a dedicated line to connect the calls. Call switching refers to the way calls are handled on a mobile network.

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

What are the 2 benefits of Packet-switching?
The Purpose of the IP Network Layer (3) of the OSI Model is to perform packet switching from one network to another. Packet Switching is a process of receiving a packet via a routed protocol on a single network and switching to another in such a way that a route to a destination can be reliably achieved (routing) via a routing protocol. Routing is processes of taking multiple network paths and by using an algorithm decide a metric which will determine the most reliable path a packet may take and store it in a table for future reference (routing table). Routing protocols like RIP use algorithms to generate and decipher a list of paths to any particular routed network. Information that is used in this determination includes hop count, reliability and link speed. Today it is widely understood that packet switched networks are superior to circuit switching. IP Multiplexing is more simplified than circuit switching and combines ability to route packets around failures which are measured and predetermined by routing protocols 24/7 365 days a year. One must however come to understand the inherent differences between routed protocols like IP and routing protocols like RIP to begin to develop a clear understanding of switched networks.
Describe how packet loss can occur at output ports?
Output ports can transmit only a single packet in a unit of time (the packet transmission time), the arriving packets will have to queue for transmission over the outgoing link. There could be more packets arriving from the switching fabric at the output port while the output port is still working on sending the packets that are already on the queue. Eventually, the number of queued packets can grow large enough to exhaust the memory space at the output port, in which case packets are dropped or lost.
How do you test an impulse line and why it is necessary?
The voltage is measured by high and low range. Measurements are referred to as r.m.s. , switching impulses reflected by line to line, earth to line contact.
