This is easy to calculate due to the mask used. The network address would be 10.10.10.0 and the broadcast address would be 10.10.10.255.
What are the three best ways to see if your routers serial port is dce or dte end?
1. The command show controllers serial [interface number]can be used to determine whether your serial interface is a DCE or DTE interface. An abbreviated listing of the displayed results for the show controllers serial 0 command is shown. The Serial0/0 interface is a V.35 DCE cable. This command should be used when you have an RJ-45 connection.
2. The V.35 cables are typically labeled to indicate whether they are a DTE or DCE cable.
3. Inspect the end of the V.35 cable to determine whether it is made (DTE) or female (DCE)
Can YouTube ban your IP address?
Yes and No. They can but it would be pointless because you can always change your IP-Address by reconnecting your Internet Connection (unplug your Internet-Modem). And your IP-Address would probably be assigned to someone else after some time, so it doesn't make sense to ban IP-Addresses.
What is the difference between server and domain?
1. Click on your desktop 2. Hit the F1 key 3. click on "User and system guides 4. Click on "Windows Glossary 5. Look up your terms of Server and Domain 6. Now you are a computer geek!
The easiest way (and reliable but not cheapest) is to rent a T1 line have it run between the buildings. If that's not an option then I would look into a wireless point-to-point solution. Some of the higher powered antennas available today can reach 16 or so miles, which would more than suit your needs. Another option is using a laser connection, but this requires line-of-sight between the buildings.
Wireless directional high-gain antennae would be cost-effective. T1 lines run $1k/mo or so.
DSL or Cablemodem at each end and VPN can also be cost-effective, but probably much slower than Wireless.
The fastest method practical to connect two points a reasonable distance apart is to use fibre optic cable. Many industrial parks have their buildings connected with fibre cables, and it can be very simple to connect a 100Base-F bridge to both ends of that cable. This would get you high performance, very reliable connectivity with no monthly charge.Cable and DSL are poor solutions, because they tend to severely limit "upload" speeds, and, frankly, are unreliable in anything other than business-class service levels, which are drastically (x5 or more) expensive than consumer versions. A T1 service can be expensive, but not always. T1 service between two buildings will actually require (2) T1 links, as the links go from each building to the telco Central Office. T1 service is usually priced by distance from the CO. You would not have to pay ISP service on top of that, so $300/month per T1 is not an unreasonable expectation for much of the US. Besides these options, there is also a microwave transmitter, which, while modestly expensive, can work through significantly poorer weather than WiFi, and has no re-occurring costs.
Overall, the easiest way to do it is via the wireless solution mentioned above: you will need an special-purpose antenna (which are easily available) to attach to a standard Wireless Router (actually, you need to read the documentation, and make sure that Router can act in Bridge Mode). The antenna will have to be attached to the outside of the building, and the cable between the antenna and the Router should not be excessively long (a couple of meters or so, in the best case).
Finally, if both buildings' networks already have Internet access, you can buy a VPN solution, to create a virtual network connection between the two buildings. You will most likely want a small hardware VPN device on each end of the connection, which will cost a few hundreds of dollars each.

What does the twisting of the wires achieve in a CAT-5 cable?
It reduces the opportunity for the signals on one pair to be transferred accidentally to a different pair.
How do you prevent wireless routers from being cut off by wireless home phones?
To avoid interference from devices such as wireless telephones you need to switch the channel your network uses. How you do this varies depending upon which make of router you are using. In general you would log into the router via a web browser, change the channel (usually under Wireless or Network settings) and then save your new settings. You may have the option to select Automatic channel selection which may be suitable for your needs.
What is a Wireless network that is designed to cover a wide area and is made up of numerous cells?
a MAN (Metropolitan Area Network) is a wireless network with roughly the coverage of a city.
No idea. Below information obtained here: http://support.microsoft.com/kb/169289 may help. DHCP (Dynamic Host Configuration Protocol) is a standard protocol defined by RFC 1541 (which is superseded by RFC 2131) that allows a server to dynamically distribute IP addressing and configuration information to clients. Normally the DHCP server provides the client with at least this basic information: • IP Address
• Subnet Mask
• Default Gateway Other information can be provided as well, such as Domain Name Service (DNS) server addresses and Windows Internet Name Service (WINS) server addresses. The system administrator configures the DHCP server with the options that are parsed out to the client.
Will Windows 98 recognize a wireless driver card?
Windows 98 will detect that a card has been plugged in. Whether or not it can USE it depends on whether the card has Windows 98 drivers available, and if you have installed them correctly. Most wireless A, B, and G cards have Windows 98 drivers, but very few N cards do.
What is the bandwidth of TCP-IP protocol?
TCP-IP is a protocol, not a transmission medium. Bandwidth doesn't affect it.
I can get 125 feet outside of my house and still connect to my 3G enabled router. I got additional range by locating the router upstairs in the house. The router uses a Sprint 3G USB modem that can be removed and used directly in a laptop if you want mobility.

How is data transported in a wireless network?
It's transported with wireless protocols (802.11 standards) through the air on different frequencies. Most common frequency used for wireless data is 2.4 GHz. Many newer wireless technologies are moving to different frequencies due to congestion on 2.4
You are supposed to remember that or write it down. If you do not have the key, you will have to set up a new one.

Difference Table between micro computers and mini computers and main frame and super computers?
micro computers can occupy physically a small amount of space compared to main frame and mini computer, as we all know for today that super computers are the most fastest high performance system and also has a largest memory.
What is an example of a device that communicates through data transfer?
For example, personal digital assistants and cellular telephones communicate with desktop computers through data transfer.
What are the benefits and downfalls of wireless networking?
Wireless networking has a few ups and downs. The most notable is that cable does not need to be run in order for the network to exist. Computers are able to connect to the internet and communicate amongst each other without the need of CAT5e or CAT6 (Gigabit) being run to a Router, Network Switch, or Hub. This allows the network to serve a decent area and makes setting up a home network easy. Prior to wireless networking one would have to run cable to the computers in each room to a "gateway". Another positive is that WiFi networking (now-a-days) is quite easy to setup. Any home user is capable of setting up a multiple computer network via WiFi. Now with connection wizards and the such, one is able to configure a wireless network in under 30 minutes.
Now for the downfalls to wireless networking. One of the biggest ones is connection security. Broadcasting information wirelessly results in the ability for the information to be intercepted and captured. This is where wireless security steps in. There are numerous types but as a general rule of thumb, No important information such as Social Security numbers, Bank Account or Credit Card information should be transferred over a wireless connection. Even if you use WPA2-AES (one of the strongest forms) confidential, classified, or sensitive information should not be transferred via a wireless connection. A skilled hacker can also hack your wireless network, and use it for their possible misdeeds including downloading pornography, using it to attack another network and even steal your information. Another caveat to the use of wireless networking is range. Most wireless networks have limited range without the use of numerous AP's (access points) or antennas. (this also affects security) The amount of walls and their contents can affect signal reception as well.
Can you steal internet from a wireless router?
If you are using non-secured or WEP type of network, it's more than possible.
