hahaha... your dumb... people answer other people's questions. When you first visit the website before putting in your question look at the website and it asks you if you can answer any of the questions that other people are asking and so many people answer them and that's how you just received your answer to your question ;)

Yes, its actually very fun to answer questions. Although, that would be a sick computer that could answer questions this well.

An Incident is an unplanned interruption to an IT service or reduction in the quality of an IT service. Failure of a Configuration Item that has not yet impacted service is also an Incident.

Incidents are classified as Regular and Major Incidents.

Different organizations will have different definitions for what constitutes a Major Incident. For some organizations, the trigger for 'calling' a Major Incident is when a certain number of users have been impacted. For other organizations, the trigger may be the actual or potential financial loss from the loss of service. If the actual or potential financial loss is over a certain amount, the Incident becomes Major. For some business areas in some industries, there may be risk of injury or loss of life if particular services are not available. Again, this may be the trigger for the Incident becoming Major. Reputational damage to the organization can be another trigger.

someone please tell me what an analogue connection is...:(

both S and R go high at the same time..this may lead to oscillation or an invalid set

Make a mathematical calculation or computation....

list three advantages of AOI logic

It shows the approximate download (downstream) and upload (upstream) speeds in either K bits per second or Mega bits per second at that particular time. The speed may vary depending on what type of service you have (cable, satellite, dsl) and how many other users are using those resources at the same time.

Cable subscribers might find the internet speed lower especially when lots of other users are online at the same time. DSL subscribers usually do not see that kind of slow down as the feed comes across your telephone line.

when ethernet cable is plugged in it is detected by ethernet card. if the cable is connected to network it detects that network and dispalys " you are connected to network"

Best for what?... 512 is faster then 256.

Mediacom is the best provider for DSL Extreme services. They have great services and packages to support the DSL Extreme package/service. The next best would be Direct TV.

It needs a wireless card or it should be connected to computer connected to the wireless router you are using for your network.

A cable modem made by Motorola can be purchased at places like Best Buy. You can also contact Motorola or visit their website for information on how to buy one.

You cannot. Before we explain why, let's first examine how we actually record audio, then we'll look at how we convert it to the digital domain.

In order to record a sound wave, we first have to capture the vibrations made by the sound. Before the advent of electrical recording, this was achieved using a horn. This transmitted the sound to a moving stylus which vibrated in sympathy with the sound. When the vibrating stylus was brought into contact with a rotating cylinder, it etched a groove in the surface. As well as rotating, the cylinder also moved horizontally, thus the groove spiralled across the outer face of the cylinder. Once recorded, the same device could be used for playback; the rotating cylinder vibrated the stylus and those vibrations were amplified by the horn, reproducing the original sound.

With electrical recording we use a microphone instead of a horn. A microphone is simply a loudspeaker working in reverse. The microphone diaphragm vibrates in sympathy with the sound wave, which in turn moves a coil back and forth within a magnetic field, thus creating an electrical signal which is analogous to the sound wave. If we pass that same signal to a loudspeaker, we can recreate the original sound, just as we did with the horn and stylus.

The moving coil has a limited range of movement within the magnetic field. If we say that -1 represents the full extent inwards and +1 the full extent outwards, it follows that 0 is the transition point between the positive and negative phases of the sound wave. 0 is also the resting point of the coil when there is no sound at all. Although we are imagining numbers at this point, they are completely imaginary; we are still in the analog realm not the digital domain.

In order to convert the electrical signal for the digital domain, we need to take a snapshot of the coil's position at a given moment in time. For accurate reproduction we'd need an infinite number of snapshots, however the human ear is quite forgiving and we find that 44,100 snapshots per second (44.1 KHz) is sufficient to reproduce sound with high-fidelity. This is because the human ear has a frequency range of 20 Hz to 20 KHz, and we need at least twice as many samples per second to capture both the positive and negative phases of 20 KHz sound. CD-quality audio is 44.1 KHz for that reason. Once recorded we cannot improve the fidelity -- we can only lose fidelity -- however by using a higher frequency sampling rate, such as 96 KHz, we have sufficient fidelity to cater for all forms of mainstream digital media (such as BluRay). Fidelity is the physical difference between the original sound and the recorded playback of that same sound. At 44.1 KHz, most people won't notice any difference at all even though the physical difference is quite substantially different.

As well as the sample rate we need to consider how we store each sample. Given that the coil moves within a working range of -1 and +1, the position of the coil at any given moment can be converted to a real number within that range. However, although the range is relatively small, the set of real numbers within that range is as infinite as the set of all numbers; it's what we call a "small infinity" because it's an infinite set within a much larger set of infinities.

The only way to digitally represent an infinite set of values is with an infinite number of digits or bits. That's clearly impossible, so we need to limit our range in some way. With 16-bit recording we have 65,536 unique values available (all integers in the range -32,768 to +32, 767), thus we must scale our set of real numbers to fit within this range, rounding up or down to the nearest integer. Each additional bit doubles the range of integers thus the fidelity of 24-bit is 2^8 times that of 16-bit.

Now -- to answer the actual question -- converting analog audio to digital audio cannot be achieved with software of any kind, it can only be achieved with hardware. This stands to reason because software can only operate upon digital information stored in the computer's memory which means the conversion has to happen before the software "sees" that information; it cannot process what it cannot "see". But hardware can easily convert an analog electrical signal into a digital one, it's simply a matter of designing the appropriate circuitry.

To convert audio signals from analogue to digital we need a device known as an analogue to digital converter or ADC. The ADC takes a bandwidth-limited analog input (anti-aliased to eliminate all frequencies greater than half the sample rate) and produces a digital output. Once converted to a digital form, we can easily store it in a computer's memory. The conversion itself is trivially simplistic and is really no different to the way we would manually scale a real number in the range -1 and +1 to an integer in the range -32,768 and +32,768.

We can adjust the conversion insofar as we can amplify or attenuate the ADC input signal (the input gain), the sampling frequency and the bit-depth. But while we can perform these adjustments with software (communicating via the hardware's device driver), the conversion process itself is handled entirely by the hardware.

The reverse process is achieved with another piece of hardware known as a digital to analog converter or DAC, which converts the digital values back to electrical signals of the appropriate amplitude.

Note that not all sound originates in the analog world but must be converted to the analog world in order for us to hear it. For instance, computer-generated sound is entirely digital but until we pass it through a DAC (and subsequently through an amplifier and speaker) we cannot hear what it sounds like.

All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).

You have to choose which router is the main one. After that you can configure second router to create "bridge" with the main one.

It's better if you have both routers of the same manufacture and model. Many routers even so can be configured for "bridge" usually do not work with different models and manufactures.

You would need to go to their website intro page for more information.

My ISP is comcast so I don't know if you get a different page if you're not (i.e. the page I see has a 'start now' button).

If not, try searching for "comcast personal web host" and you will get the link I used before being redirected to the above page.
