Local Area Network

Layer 1. Psychical

If it was green before and turned orange it means you have problems with your wired connection. It can be as simple as unplugging and plugging the cable. And as bad as that the NIC went dead. Start with testing the card using ping 127.0.0.1. It will test your NIC. Then test the card on another end of the cable and test cable.

Moroon check google!

its a long process

You can use this to try and parse it: IPAddress.TryParse

Then check AddressFamily which

Returns System.Net.Sockets.AddressFamily.InterNetwork for IPv4 or System.Net.Sockets.AddressFamily.InterNetworkV6 for IPv6.

EDIT: some sample code. change as desired: string input = "your IP address goes here";

IPAddress address;

if (IPAddress.TryParse(input, out address))

{

switch (address.AddressFamily)

{

case System.Net.Sockets.AddressFamily.InterNetwork:

// we have IPv4

break;

case System.Net.Sockets.AddressFamily.InterNetworkV6:

// we have IPv6

break;

default:

// umm... yeah... I'm going to need to take your red packet and...

break;

}

}

Yes.

The problem with security and peer-to-peer networks is that the security is up to each individual workstation. Some may have a very secure system and some may not have any security at all.

With a client-server network the network is managed by (in the case of Windows) a domain controller, which can enforce security for all other systems in the network. Using group policies the individual workstations can be made to conform to the policies of the organization and can be managed from a central source.

In a peer-to-peer situation there is no enforcement or auditing of administrative policies other than having someone look at each individual system, which is very time consuming.

The host portion specifies the particular network interface's address. The network portion specifies the network address.

A set rule for transfer data

a collision domain is a group of devices where traffic from any one of them could collide with traffic from any other member of the same group. some devices help to shrink collision domains, like switches, while other devices can extend the size of a collision domain (like a hub).

Router

Network + Guide To Networks Review Question Chapter 6 #15

technically the answer is D All of the above. the book lists the correct answer as "all of the above."

The connection establishment process actually accomplishes
several things as it creates a connection suitable for data
exchange:
o Contact and Communication: The client and server make
contact with each other and establish communication by
sending each other messages. The server usually doesn't even
know what client it will be talking to before this point, so
it discovers this during connection establishment.
o Sequence Number Synchronization: Each device lets the
other know what initial sequence number it wants to use for
its first transmission.
o Parameter Exchange: Certain parameters that control the
operation of the TCP connection are exchanged by the two
devices.

Router - responsible for communication between computers.

Lan cable(s) - you need it(them) to connect your computer(s together or/and to internet) .

Yes, Cable length is always printed on the cable wire. As I have recently checked cables of peterstechnology.com cable length was printed with ISI certification mark & it's company logo. So anyone can easily recognize the medical cable.

Thank you

There are no layer 1 switches; switches run at layer 2 or 3. A hub is a layer 1 device.

cheap and simple connection use utp if noise or interference have to consider then co-axial

YES

Netstat reports on the common tcp/ip protocols, including (but not limited to) TCP, UDP, ICMP, socket connections.

Transport layer is known as the host-to-host layer.

Also data link layer is responsible for point-to-point or point-to-multipoint transport of data.

This sounds like a homework question.....hmmmm.

Anyway- if there's a break in a bus topology, the nodes that are downstream from the break are cut-off from the rest of the network.

In a ring topology, the nodes on both sides of the break will loop the path (self-healing) back towards the ring, so every node is still communicating with each other.

They are not the same; a port number indicates a listening program that will receive a packet. That number exists on the target system, but the port number itself has no identification that would allow a packet to be routed or delivered to it.

An IP address identifies a system on a network for delivery purposes. Once the packet arrives, however, it has to be given to an appropriate program listening for a protocol. that is what the port number is for.

• Devices th make up the network.
• Media that connect the devices.
• Messages that are carried across the network.
• Rules and processes that govern network communications.
• Tools and commands for construction and maintaining networks.
