Local Area Network

A method of and system for conferencing a plurality of clients over a local or wide area network using multicasting where the conferencing function is distributed between a server and the clients. The invention takes advantage of certain capabilities of existing client equipment and multicasting capabilities of the server to distribute the conference function between the server and the clients in a conference call over a LAN/WAN in a way that reduces network congestion and protocol complexity. The system of the present invention for providing conferencing over a local or wide area network, includes: a plurality of clients connected to the network for transmitting signals to and receiving signals from the network; and a server connected to the network for receiving a plurality of signals transmitted from the plurality of clients, mixing the received signals to create a single multicast signal, and transmitting the multicast signal to each of the clients. Each of the plurality of received signals is made up of data packets of a defined length. The server includes: a jitter buffer for synchronizing the data packets received from the plurality of clients; an adjustable gain/loss controller for applying adjustable gain/loss to the synchronized data packets--according to speech activity and average level at each client signal; a mixer for mixing the data packets of the plurality of signals to create the single multicast signal for transmission to each of the clients. An individual client receiving the multicast signal transmitted from the server includes an echo controller for estimating and removing, from the multicast signal, a signal component corresponding to a signal transmitted from that client. With the rapid development of the Internet in recent years in conjunction with the TCP/IP transmission protocol and the latest version of the hypertext (HTML) facilities, new possibilities have come into existence for the use of the network for remote control of experiments in research labs and other practical systems. Using graphical software languages client-server systems can be easily designed. Client-server systems have some general advantages when compared with remote-access systems (RAS) or proprietary (single-solution) systems. The disadvantage of http-based client-systems is the need for a minimum stable transmission rate of 7 kbyte/second. Router, hub and switcher technologies reduce the effective transmission rate of high speed Internet connections. In recent years gateway systems for remote control have become available for most measurement and instrumentation bus systems and this effectively allows direct access via LAN/Internet with a minimum of transfer data-rates needed for control BHUSHAN PURANIK

FTP uses TCP because the file transfer has to be correct.

TFTP uses UDP for speed, but not everything will get there.

In computer networking a work group is collection of computers connected on a LAN that share the common resources and responsibilities. Workgroup is Microsoft's term for a peer-to-peer local area network.

Look at your lab sheet that was given to you in class, the link to the answer is on that sheet. Since you are so lazy to look for yourself this is the answer,

42 dB

20.1 dB

100 dB

20.2 dB

You choose what is the right one. ;)

its the 2nd one

USB - connects to devices such as printers, external hard-drives etc.

3.5mm sockets - for connecting speakers, microphone or a head-set.

HDMI - for playing back High-definition content on the computer.

9-pin D - for video output ot a monitor.

It depends on the area covered. It may also be a CAN or Campus Area Network.

Network Neighborhood is the Microsoft Windows name for a way/method to browse the Local Area Network. Network Neightborhood has now become My Network Places in Windows XP. The function remains the same.

1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).

If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.

You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.

There are four possible combinations of

encoding techniques

-Digital data, digital signal

-Digital data, analog signal

-Analog data, digital signal

-Analog data, analog signal

There are many answers but the best one will depend on your budget and your needs.

WindowsXP Pro, and some Vista versions have remote desktop included at no cost.

There are also dozens of third party applications like PCAnywhere, or VNC.

There are also website based systems like go2mypc.com

Typically a LAN is connected to other networks (WANs, etc) via a router, used as a default gateway device.

Network switches are used to connect two different segments of a LAN. If a LAN has to many nodes (objects on the LAN) that are communicating, the chances of a collision occurring are higher. To lower this chance and to increase bandwidth add nodes that communicate with one another often (such as two computers and a printer) then connect the output to the LAN (everything else). This will keep bandwidth lower and will lower collisions.

However a switch isn't allways the way to go. If you have a smaller network (say a max of 10 computers or so) you might want to use a router instead. Routers help direct trafic. So two nodes can talk while others on the same LAN are too!

ip6 can handle many more addresses than ip4 - allowing more people to join the Internet.

The OSI model is used today with current networking standards. It covers more than the more limited TCP/IP model.

Since this is a class B network you have borrowed 8 bits for subnets. This leaves 8 bits left (1 octet) for clients/workstations. That gives you a maximum of 254 clients per subnet.

The subnet mask itself is an IP Address so it is also 32 bits

It would say so in the bottom corner.

Usually a gateway or proxy is responsible for hiding internal networks.

Get a program to scan and create the network map. After you have created the map, use annotations to mark where they are in the building.

LAN: Limited geographical area usually within the same building.

WAN: Larger global Network with no physical boundaries.

A VPN provides a certain amount of anonymity when using any Internet-connected device. It works by rerouting your IP (Internet Protocol) address so that your final address when connecting is different.

This conceals some information that could be used to track you to a city. Although it is unlikely that you can be tracked further, your device can also be identified from your IP by finding your Internet Provider and demanding a list of who an IP was assigned to. Using a VPN negates this possibility.

It depends on how many subnets you have and how many ports you router has. Usually each port in router is devoted to on subnet, you can do math for your situation.
