Define piggybacking and its usefulness?
Piggybacking refers to the practice of leveraging an existing system, resource, or idea to gain benefits or enhance functionality without starting from scratch. In technology, it often involves using another network's infrastructure to access services or data. This approach can save time and costs, promote innovation, and foster collaboration by enabling users to build upon established frameworks or resources. It can be particularly useful in scenarios like app development, where developers can use existing platforms or APIs to enhance their applications.
What is the bitrate of the signal in which bit lasts for 0.001 seconds?
The bit rate of a signal in which the time per bit is know can be easily calculated. The bit rate for a signal where a bit lasts for 0.001 seconds can be found directly by inverting the time per bit. But let's look at it this way. Your bit takes 0.001 seconds to be completed. That's 1/1000th of a second. That's a rate of 1/1000th of a second per bit, isn't it? Yes, it is. But bit rate is bits per second, and you have seconds per bit, right? Yes, you do. It turns out that 1/1000th of a second per bit is exactly equal to one bit per 1/1000th of a second. It is most important that this is clear. Your bit rate is one bit per thousandth of a second. But wait a minute. Bit rate is normally measures in "x" number of bits per one second, and the bit rate here is expressed here as one bit per 1/1000th of a second. Here's what it looks like: 1 bit

1/1000th seconds Looks kinda ugly, but that's what it is. Now multiply both the numerator (1 bit) and the denominator (1/1000th seconds) by 1000. That makes the denominator turn into a 1 which is what is needed to convert this mess into bits per 1 second. The numerator will be come 1000. The answer is now clear. It's 1000 bits per one second, or 1000 bits per second, or 1000 bps, or 1k bps.

Have cable modem what is needed to connect three computers to internet?
It depends on model. Some modems come with a wireless router. If yours has wireless interface, you will able to connect your computers wirelessly.
Usually what you have is a modem with one LAN port. If you want to connect your 3 computers to the same modem you need to get a wireless router. It will allow you to connect your computers using wireless or cable. Switch in such case might not work because of internet provider policy.
Where do you get your host name for your router?
Most home network routers don't have a host name, although it is possible to give it a host name using a DNS server. I'm assuming that you wish to configure the router, and for that all you need is it's IP.
You need to be connected to your router to perform these steps (either by WiFi or ethernet cable).
In Windows 7 click start type "cmd" without quotes in the search field & hit enter.
For Windows XP click start>run type "cmd" & press enter
Inside the the command prompt (a blackbox with white text) type "ipconfig" without quotes and press enter.
You will be presented with you network info, look for "Default Gateway" next to it there will be your routers IP (e.g. 192.168.1.1), your number may be different.
After you have gotten the number type it into the url field of your web browser and you should see a configuration page for your router.
Can you fit a BNC connector to a Shielded twisted pair cable?

What precautions should you take prior to installing an network card?
Shut down your computer, leave it plugged in. Open your case, take your shirt off and touch the case with your bare arms. Keep your arms resting on the case. Now you are grounded. Open the package with the card while staying grounded. Insert the card carefully but firmly. Follow instructions as to to which slot it should be plugged in to. After you install the ethernet card. Start with plug and play or use the instalation disk that came with the card. If that's too much for you, call customer service. Grounding prevents ESD, Electrostatic Discharge. Like when to touch a door handle and it shocks you briefly. Shocks like this are fatal to circuit boards.

Both. Increasing the gain is like driving a dumptruck down the street, but its going to cause alot of damage. Increasing the gain on your antenna can hear everything like putting a horn to your ear, but you risk damaging your ear drum.
Similarly, boosting the gain on your transmitter can result in jamming like RF devices within the transmitted frequency band. This could end up resulting in an FCC violation. Increasing the gain of your receiver can result in lowering the signal to noise ratio. This will result in rising the noise floor and receiving high static fundamentally losing the signal in the noise.
A computer that stores and distributes newsgroup messages is called a newsreader?
No; it is called a news server or NNTP server. (NNTP, or Network News Transfer Protocol, supports the handling of newsgroups and their content.)
A newsreader is the client that connects to a news server to read, post, or otherwise interact with newsgroups.
When is a user's access token generated?
When the process of ussuarial token accessorization has began to take place in the industry of micropetrolianology. ( It will take place in 2010, the 5th of August)
How bit rate is 2 times of baud rate in Qpsk?
Although QPSK (quadrature phase shift keying) refers to an instance when two bits are processed at once, this does not mean that the actual bit rate is twice that of the baud rate.
How does one use an SSL unblocker?
SSL unblockers are used to unblock websites that have been censored. The software is quite simple to use. One needs only to download the application and run it.
Why would one need to use an FTP download?
The reason one would need to use an FTP download is for your computer. It uploads and save different documents for one device to another for easy travel access.
Can you track someones ip address up to an actual location or address?
Not down to the exact degree of latitude/longitude, but you can get pretty close to where the computer using that IP is by tracking the IP.
