Where can one find more information about virtual hosts?
Finding more information about virtual hosts is not very challenging at all. In order to find more information about virtual hosts, one can visit the GoDaddy website.
What are some dedicated virtual serving hosts?
A virtual serving host offers virtual server facilities to users. Virtual servers are virtual machines that are functionally equivalent to a physical machine, even though multiple virtual servers can be hosted on a single physical server. Some examples of virtual server hosts include DreamHost, Soft Layer and GoDaddy.
What is the ability to respond to multiple IPs called?
Is called virtual hosts.

You can create virtual hosts by hostnames or IP addresses Explain the basics of how each type works?
IP-based virtual hosts use the IP address of the connection to determine the correct virtual host to serve. Therefore you need to have a separate IP address for each host. With name-based virtual hosting, the server relies on the client to report the hostname as part of the HTTP headers. Using this technique, many different hosts can share the same IP address

Explain the Concept of multi-protocol encapsulation in ATM networks?
Multiprotocol Encapsulation over ATM From Wikipedia, the free encyclopediaMultiprotocol Encapsulation over ATM is specified in RFC 2684. It defines two mechanisms for identifying the protocol carried inATM Adaptation Layer 5 (AAL5) frames. It replaces RFC 1483, a standard data link access protocol supported by DSL modems.RFC 2684 describes two encapsulation mechanisms for network traffic: Virtual Circuit Multiplexing and LLC Encapsulation. Either mechanism carries either routed or bridged protocol data units, and DSL modems often include a setting for RFC 1483bridging. This is distinct from other "bridge modes" commonly found in combined DSL modems and routers, which turn off the router portion of the DSL modem.In VC Multiplexing (VC-MUX), the hosts agree on the high-level protocol for a given circuit. It has the advantage of not requiring additional information in a packet, which minimises the overhead. For example, if the hosts agree to transfer IP, a sender can pass each datagram directly to AAL5 to transfer, nothing needs to be sent besides the datagram and the AAL5 trailer. The chief disadvantage of such a scheme lies in duplication of virtual circuits: a host must create a separate virtual circuit for each high-level protocol if more than one protocol is used. Because most carriers charge for each virtual circuit, customers try to avoid using multiple circuits because it adds unnecessary cost.In LLC Encapsulation the hosts use a single virtual circuit for multiple protocols. This has the advantage of allowing all traffic over the same circuit, but the disadvantage of requiring each packet to contain octets that identify the protocol type, which adds overhead. The scheme also has the disadvantage that packets from all protocols travel with the same delay and priority.RFC 2684 specifies that hosts can choose between the two methods of using AAL5. Both the sender and receiver must agree on how the circuit will be used, the agreement may involve manual configuration. Furthermore, the standards suggest that when hosts choose to include type information in the packet, they should use a standard IEEE 802.2Logical Link Control (LLC) header, followed by aSubnetwork Access Protocol (SNAP) header if necessary.The AAL5 trailer does not include a type field. Thus, an AAL5 frame is not self-identifying. This means that either the two hosts at the ends of a virtual circuit must agree a priori that the circuit will be used for one specific protocol(e.g., the circuit will only be used to send IP datagrams), or the two hosts at the ends of a virtual circuit must agree a priori that some octets of the data area will be reserved for use as a type field to distinguish packets containing one protocol's data from packets containing another protocol's data.
Why is virtual hosting necessary?
Virtual hosting allows multiple hosts to share computer resources while allowing them to use maintain different host names.
Where is the Thruxton racing circuit located?
The Thruxton racing circuit is the fastest racing circuit in the United Kingdom. Thruxton is located in Hampshire, England and hosts a variety of motorsports.
How can one acquire a virtual private server?
Online there are many hosts from which you can acquire a virtual private server. Costs can be quite reasonable if you shop around. In the long run a virtual private server can save you money.
What is the Difference between datagram network and virtual circuit network?
Not a whole answer but a small try :)In a Datagram Network, there's no "network-layer-connection" between the two hosts. So Theres no garuanteed bandwith and the packets may take different paths.In a Virutal Circuit network, its oppositly and a connection is established.------------------------------------------------------------------------------------------------------------ •There are a number of important differences between virtual circuit and datagram networks. •The choice strongly impacts complexity of the different types of node.•Use of datagrams between intermediate nodes allows relatively simple protocols at this level,-but at the expense of making the end (user) nodes more complex when end-to-end virtual circuit service is desired.•The Internet transmits datagrams between intermediate nodes using IP. •Most Internet users need additional functions such as end-to-end error and sequence control to give a reliable service (equivalent to that provided by virtual circuits).•This reliablility may be provided by-the Transmission Control Protocol (TCP) which is used end-to-end across the Internet,-or by applications such as the trivial file transfer protocol (tftp) running on top of the User Datagram Protocol (UDP).
