Computer Networking

It is a Hybrid routing protocol.

It provides configurable metrics.

It establishes formal neighbor relationships among routers.

If you are referring to a modem, the it is a device that allows your computer to connect to the internet.

Probably QOS(quality of service) features would be nice in an advanced switch as well well as the ability to create vlans, and turn off certain undesirable protocols. Most of these features can be implemented from a router as well. I would also compare expandability and the speed of the backbone or (plane) that interconnects all of the blades in a large switch. I would also have at least a spare blade and powersupply for the switch if it's a mission critical switch like the switch at the network core.

data link connection identifier (DLCI) is a channel number. Think about is like a gate on a airfield. You being data, that is using a gate to get your destination.

The Icon will not appear when you are connected with Broadband. You can force it to appear but it is not necessary. You are connected 24/7.

A layer appears to be communicating directly with the same layer at the other end of the link (i.e. its peer). What is actually happening is that the data is being passed down to lower layers for transmission and is passed up again at the other end.

It is extremely important to know what the existing topology of your network is before purchasing any other equipment, because if you buy the wrong type of equipment for the topology the network may not work.

Secondly, when buying equipment you need to consider future expansion; what may work now may be too slow in the future or too limited in the future, given the number of new devices you may want to add to the network. You always need to plan for the future.

Maybe what you are seeing is a exploit technique used to determine operating system. To fingerprint a network, people use an IP source 0.0.0.0 and a IP destination of 0.0.0.0, set the ACK bit, and broadcast at the Ethernet layer

There are some great YouTube videos demonstrating the techniques... check them out.

Q.8 What is the difference b/w OSI Reference Model and TCP/IP Reference Model? The open systems interconnection (OSI) reference model describes how information from a software application in one computer moves through a network medium to a software application in another computer. The OSI reference model is a conceptual model composed of seven layers, each specifying particular network functions. As in the OSI model, data is passed down the stack when it is being sent to the network and up the stack when it is being received from the network. The four-layered structure of TCP/IP is seen in the way data is handled as it passes down the protocol stack from the application layer to the underlying physical network.

you can not just control a system using ip address.(thats hacking)

you would to use progames like network admin tool

parallel port

ping stands for packet internet groper. it is use for echo request and reply message to check the physical and logical connectivity of a machine on an internetwork

Dijkstra

The Link for a switch connection is isolated from other data traffic except for the messages with the same IP address class.

i.e the IP adressess of the same class

In the world of networking, reading has become a conversation of give and take.

If you represent it in Hexadecimal, sure. That's very uncommon in IPv4, but just fine for IPv6.

Eurotunnel is the name of the company which owns and operates the Channel Tunnel, as well as other business interests.

The Channel Tunnel connects the United Kingdom and France. It runs between Folkestone in Kent and Sangatte near Calais in Pas-de-Calais.

Because that would only allow one address, and two are reserved (One for broadcast, one for a gateway).

So that would mean that the lowest possible subnet mask which would be usable would be 255.255.255.252, with three spare addresses. Even so, this would only allow one additional terminal on the network.

Both sides of the serial communication must be configured for parity. Then every 8th bit is defined as the parity bit.
