Computer Networking

Yes TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

A. Traffic is classified based on quality of service requirements.

D. Digital movies are always assigned to the high-priority queue for processing.

1. As new neighbors are discovered, entries are placed in a neighbor table

2. If hello packets are not received within the hold time, DUAL must recalculate the topology.

3. The reported distance is the distance to a destination as advertised by a neighbor.

No - you use a Wifi card or USB Wifi adapter to access the router. Bluetooth operates on the same frequency as Wifi (2.4Ghz), however the transmission protocol is different and at a lower power.

Convert each decimal number to a binary number separately. You can use Windows calculator for this (in the menu you will find a command to switch between standard calculator and scientific calculator). Each group of bits must be completed to 8 bits - fill out with zeroes on the left, until you have 8 bits (so for the the second part, the calculator will give you 1101011 - add a zero to the left to get 01101011).

If you want to do the conversion with pencil and paper, ask a separate question, or research existing questions, something like "how do you convert decimal to binary".

The computer is a tool, and one of its uses is for access to the Internet. The Internet is a series of disc drives in server computers that contain data. The connection between a computer and the Internet is a data channel.

Internet Protocol, or IP, puts a header on every packet that it sounds out. This header is the overhead. All protocols, such as TCP or UDP, will put a header on the packet. The IP header contains information such as source IP address and destination IP address and is used by routers to figure out where to send the packet.

ex. you send your friend a 1kb file, but it takes up 1.5kb of bandwidth due to overhead

RS 530 has a logarithmic degradation on cable length as the data signaling rate increases. These are some of the readings on the chart: up to 90k b/s - 1.2k meters.....400k b/s - 300 meters....1.2 M b/s - 100 meters approx......2 M b/s - 40 meters....6 M b/s - 20 meters...10 M b/s - approx 15 meters....

The purpose of Windows Network Monitor is quite obvious: it allows one to monitor all the network activity that goes into the computer and out of it, which can be useful in tracking down viruses.

Devices- 6

W= n(n-1)/2

whereby W is number of cables

n is number of devices

solution

W= 6(6-1)/2

=6(5)/2

=3(5)

=15

15 cables

There are two kinds of 'household networks', Open and Closed. Open networks can be joined by anyone at anytime. Closed networks require permission to join. When you attempt to join a closed network, a notice is sent to the Closed Network's administrator requesting that you be allowed to join. That person will respond either accepting or denying your request. (remember, once you've joined a network, you cannot leave that network for 30 days - security reasons).

A static IP address is one that doesn't change. Usually it's programmed directly into the computer or network device. Servers and routers almost always have static addresses.

A dynamic IP address is one that can change. Usually, a computer or network printer will ask for a dynamic IP address from the network when it starts up. If there is a DHCP server on the network, then it will provide the device that's starting up with a dynamic IP address.

The next time the device starts up, it might get a different IP address from the DHCP server.

By the way, "DHCP" stands for "Dynamic Host Configuration Protocol".

A common abbreviation would be 'pkt'.

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.

It performs the task of first contact between the machine and network. Main examples are Hub, Switch, Bridges, Routers & Gateway

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.

Computers can be interconnected in different ways to form a network. Such different ways of interconneconnection are called computer topologies.

There are 5 topologies. They are:

* BUS TOPOLOGY * RING TOPOLOGY * STAR TOPOLOGY * MESH TOPOLOGY * TREE TOPOLOGY

The Internet, or the World Wide Web.
