Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

What does the T mean in 10Base-T?
It stands for 'twisted pair'. 10BaseT or Ethernet cable consists of two pairs of wires twisted around each other inside an external sheath.
What are some good thesis topic?
most people enjoy doing a thesis paper on something that is happening currently. I have students that are doing their thesis on the gun control debate. Just pick a topic, figure out your stand in the battle, and use the paper to try to convince others to join you in your stand. also, only talk about your stand in the debate. do not give information in the favor of the other stand. hope this helps
In which environments would a Metropolitan Area Network be most appropriate?
Any environment that contains two or more local area networks (LAN) that are geographically close to each other but need to interconnect with each other is an appropriate environment for a metropolitan area network (MAN). For example, an University campus may have several separate LANs that need to interconnect, and would be a suitable environment for a MAN. If the LANs are widely dispersed, then a wide area network (WAN) would be more suitable.
What is the purpose of valve ports?
The purpose of Valve Ports is to let exhaust gases out of the cylinder and to let air and fuel mixture into the cylinder!
What role or roles would you assign to each of the four workstations on a peer-to-peer network?
recieve and share information or data with all the workstations in the network
How do you determine if a website uses IPv4 or IPv6?
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;
}
}
Why is media content categorized into genres?
gardeningAn important limit on the media's impact i the content the media carries
What is used to determine if the host is local or remote?
It could be said that the most "local" host is the machine you are typing on, but that realization is not always implicit in the design of the protocol you are using. Also, computers on the same physical network can be considered local, as can be considered computers within the same address space - it really depends on your definition of "local" and "remote".
If you're thinking about "geographical locality", IP address groups are assigned to countries, and then sometimes subdivided into states or cities, where applicable and possible, and there exist services on the World Wide Web that access this publicly available information in order to provide at least a rough approximation of the host's geographical localization.
However, the most common idea thought about when speaking of "local" and "remote" hosts, is the idea of logical network placing - ie. a computer will be considered "local" if it belongs to the same address space (in this case, the IP/mask calculation will be performed, and will include any specific routing information, to arrive at a conclusion).
Also, any computer you are connecting to can be considered the "remote host" - even your own! That is simply because the "other end" of a connection can be called "remote" just because it's on the other side of said connection (in this case, just the connection itself will differentiate the two sides of it). As I've pointed out above, it really depends on your definition of "local" and "remote".
It is also worth keeping in mind that from the perspective of the computer you're trying to contact, you are the remote host!
No, as long as it's used to see if the IP address is valid to get a server somewhere. If it's used to disrupt or crash systems then it would be.
What value in the address field of a Frame Relay header identifies the destination of the frame?
DLCI
What is hard disk RPM speed range?
The most common range is 5400-7200 rpm. There are also 10000 and 15000 rpm drives. Solid state drives do not operate on the same principals as disk drives, and do not spin at all.
Can you use staneless steel for a cantanna?
It shouldn't matter what type of metal you use, you might get a little more attenuation with steel. I would recommend using a tin can, the copper would clean up the signal, but not by much.
Why would you expect a CRC to detect more errors than a parity bit?
If there are two errors in a character, the parity may still be OK as two wrongs make one right, in this example. However such an error will not escape the CRC check as it is far more sophisticated and such a false positive is almost impossible to happen
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.
What part of an IPv4 address specifies a particular network interface on the network?
The host portion specifies the particular network interface's address. The network portion specifies the network address.
What are service carrier network equipment manufacturers?
Service carrier network equipment manufacturers sell telephone switching and switchboard equipment primarily to local and long distance phone companies
