There is ample confusion between latency and the bandwidth of the network. The bandwidth just defines the speed of the connection. But latency defines the delays which are incorporated in the network. There are two forms of latencies concerning networks, they are the high latency and the low latency. The high latency network is one in which the data packets are getting delayed in higher numbers while the low latency networks are the exact opposite. Of the other confusion which exists in this field is that bandwidth and latency are directly related. Some believe that latency can be decreased by opting for a high bandwidth connection and vice versa. But it must be noted that there is no relationship...

Voice mail is often considered by business owners as impersonal and irritating to their customers. This, however, is a myth and far from the truth.

Logistic Regression Logistic regression is used for binary classification problems -- where you have some examples that are "on" and other examples that are "off." You get as input a training set; which has some examples of each class along with a label saying whether each example is "on" or "off". The goal is to learn a model from the training data so that you can predict the label of new examples that you haven't seen before and don't know the label of. One of the first models that would be worth trying is logistic regression. Coding it up I wasn't working on this exact problem, but I was working on something close. Being one to practice what I preach, I started looking for a dead simple...

If you want a service that allows you to quickly find the name of the person who has called you from an unknown phone number, do not fret, because help is at hand. Earlier, you would have to turn to Yellow/White Pages, or telephone directories or search engines, but more often than not, you would end up with not much to show for your efforts. That is because Yellow/White Pages do not list mobile phone numbers and search engines generally cannot find them because people do not leave their personal phone numbers on websites where search engines can trace them. So what do you do? You can use reverse phone number searches. These services are cheap, easy and accurate. There are some 'free' services, but...

For those who have limited knowledge of DSP FIR and IIR terms may seem little bit tricky. Well FIR stands for Finite Impulse Response and IIR stands for Infinite Impulse Response. Lets see what does it mean in popular manner. All filters have their own characteristics. Characteristic are a response to a pulse applied to filters input. If we know filters response, we can easily calculate filters amplitude and phase behaviour. So filter can be imagined as a transfer function, which gives a certain response to input signal. In digital systems signal is sampled and each sample is considered as a pulse. Calculation filter response becomes quite easy task. Lets see what filter responses can be. A pulse in...

RFID: Traceless Truth

Life usually seems to me to be a series of Rorschach tests. We each interpret events and patterns through the filter of our personal history, and no two people experience the same stimulus in the exact same way. RFID means "cutting-edge technology" to one and "the end of personal freedom" to another. "Big Brother" to one and "transportation efficiency" to another. "Professional development opportunity" to an RFID software engineer and "layoff" to a no-longer-necessary inventory clerk. But now and then the ink blot is so obvious that it transcends individual interpretation. Or in the case of Canadian technology firm Creo, it is the absence of the ink blot that is so clear.

Examples of Nanotubes are Single-layer nanotubes and nanotube "ropes" and nanohorns. Carbon nanotubes, therefore, are rolled-up sheets of graphite - i.e. the same material that is used in pencils.
