Disadvantages :
ATM use cell switching. it use a 52 by long packet where 48 byte is data and 4 byte is header.

The gamepad offers several advantages over traditional joysticks and computer keyboards, allowing you to have increased control over the virtual characters you navigate. You use fewer fingers while you play a game and don't need to connect the gamepad to the game console. Understanding a gamepad's advantages helps you determine if a gamepad is right for you.
Virtual Circuit is Created. Each circuit is known by its DLCI. i.e. Data Link Connection Identifier.
If you are using a modern version of Windows (Windows 95 or latter) you will be using virtual memory. Virtual memory is NOT the pagefile and it is not an extension to physical RAM but a system that is completely integrated into the system. Applications access virtual memory exclusively, no exceptions, ever. You can not disable virtual memory. You can disable the pagefile (not recommended) but this will not disable virtual memory. The system provides a virtual environment to processes that is completely independent of how much RAM is in the system. This is an advanced system that provides many important advantages to applications and users.
Advantages are that everything in the virtual world is going to be organized for you. Disadvantages are that it is difficult to organize things in a virtual world.

Advantages of Virtual Office is you can hire many part-time workers. Less expenses for office rentals, tax exemptions, facilities for your employees. While the disadvantages are communication with your workers, physical meeting and physical location of the business.
B-ISDN is a circuit switching process. The N-ISDN is a virtual switching process (packets). ISDN stands for Integrated Service Digital Network.

The Virtual Switching is a technology allowing multiple switching functions to happen in one physical device or single functional switching to happen in multiple physical devices across network, while in the situation of a real switch, switching is conducted in one physical switch. Virtual switching technology enables a single switch to be used for many different applications. Each different function may have its own discrete performance and security controls. Using virtual switching technology, Service providers can create a dynamic service mix, as desired, without requiring new hardware and enabling the gradual evolution to include new services or a common control plane. Virtual switching is a core concept in the Multiservice network switching architecture.
Virtual PC allows you to run multiple operating systems under the same physical hardware simultaneously. Of course, multiple operating systems will have to share the same memory, disk drive and failure of the main OS will affect the Virtual PCs
advantages of virtual keyboard?
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).
Advantages of virtual microscopes include the fact that they're a great learning tool, and they require no maintenance. Disadvantages include the fact that the samples are not able to be rescanned, and the ability to manipulate images is limited.
