Computer Networking

If the modem has a power button, use that.

If not, log into the web configuration interface (use the manual to find out how), and reboot it from there.

If all else fails, unplugging the power cord, waiting for a bit and then plugging it back in... this is how its most commonly done.

You should learn more about IP addressing. Most routers (not just linksys) are 192.168.1.1

This 192.168.x.x address is only a private address, its not public. So your private address and my private address and everybody else's private address can be the same. But every public address has to be different. You cant have 2 public addresses the same or there will be huge problems. If you ever heard anything about IP6, you will know what Im talking about.

Raid adapter

Its an exam that you take in the middle of the school year(6 months) that reviews everything you have done until that point. Its usually 100 questions long. but it can vary!

Use the first key, and if that doesn't work use the second one, and so on. I have a Linksys router and I used the first key, and my DS and Wii connect just fine. Good luck!

it means mapping directly

This depends on the context of the questions your asking. A network computer would be considered any computer or operating system on the network that is addressable. In most small networks though, a small computer is often used as network server for storage or other puroses. Switches are used for connectivity in a wired network to provide connection from client to server.

The types of networks that use moderately capable computer are quite small though often consisting of merely 15 computers or less, which in terms of networking is very small.

Your Media Acces Control(MAC) Address.

In Terms of Saw blades, "TPI" stands for "Teeth per inch".

Full duplex has the highest throughput concering communication.

shift registers can be used in CDMA(code division multiple access) in communication.

What isn't network efficiency???

Physical security is having locks on your doors, security cameras in your building and security guards if needed. This can also include protection from fire, natural disasters, burglary, theft, vandalism and terrorism.

HTTP transfers data from a web server to a client

Telnet provides a virtual connection for remote access

over the setalite

try search on google.

You could provide abit more details. Though if its a wireless network check to make sure your wireless is switched on. Some software takes over and wont allow you to use the in-built windows connection manager.

Download network stumbler. See what results you get with that.

Usually its port 21. Though alot of people fail to realise that just because that's the default setting doesn't mean you cant change it.

FTP servers listen on port 21. The data transfers happen on a different port, which is usually done in passive mode, on a port above 1024.

The "Web" also known as the World Wide Web is often used interchangeably with the Internet in newspapers, blogs, and elsewhere. The distinction gets blurred with the explosion of e-mail, chat, streaming video along with the merging between computers, cellphones, and TVs.

The "Web" is the leading information-exchange service of the Internet primarily associated with the hyper-text association of web pages, content, and web servers.

The "Internet" is the underlying framework used by the Web allowing the connections of remote computers and routers, exchange of data packets, and resolution of host names into addresses.

The Internet is like the water, gas, and electrical lines in a house and the "Web" is an appliance that uses it.

You can ping a static or dynamic IP address. The only difference is that a static IP has been issued to a subscriber semi-permanently. A dynamic IP has something called a 'lease time', and is only valid until the lease runs out. This lease time can be minutes, hours, days, etc. When the lease runs out, the machine that was using it needs to request a new IP address. Many times the last IP address will be leased out again, unless another machine made a request and got it first. To ping any IP address with Windows, Click the Start Menu. Click Run. Type 'cmd' in the box and press enter. When you see the black prompt screen, type 'ping xxx.xxx.xxx.xxx', where xxx.xxx.xxx.xxx is the IP address you want to ping. If you have a router, you can test connection to it by pinging 192.168.1.1 in most cases, unless you have changed the router's IP address. After the ping command is finished, it will report how long the packets took to get there, how many were lost, etc. If you have a 100 percent loss rate, the ping failed, most likely due to no connection.

No, that is the part number. The WEP key is set by whoever originally set up the network. It is part of the configuration and is usually not recorded on the access point or router.

These domains are named using the two-character country and region codes established by the International Organization for Standardization (ISO) 3166, such as .uk (United Kingdom) or .it (Italy). These domains are generally used by organizations outside the United States, but this is not a requirement.
