Digital — system is one that uses discrete values rather than a continuous spectrum of values: compare analog.\n\nInformation -- Compiled files stored in a database in digital format.\n\nWith the combinations and of Digital Information and the ability for companies to write scripts in PHP and MySql they make the websites more user friendly and the ability to recall information on a single database using multiple files depending on the size and format of the database itself.  Makes networking possible.  Being able to go back to a site that you've visited because you've registered already.  Is a great for both the creator of that site, why - because your information is already there and you will come back to log in.  It's also great for you because by remembering a single user name and password you can pick up right at a site that you logged out of and left off, making this more convenient for you the user.  Your DIGITAL INFORMATION is stored on their databases already.\n\nDigital Information can be found anywhere a person logs in and resumes activity such as customer websites, yahoo, and other social networking activities.\n\nHope this was helpful and some what educational.\n\nMy names is James P Reardon Sr.  I am the Webmaster of BetterMember.NET  (Social Networking)  I compile and work with user information in digital format every operating day.\n\nTake Care,\nJames P Reardon Sr.\nFounder of BetterMember\nhttp://www.bettermember.net

A digital circuit is based on a small number of (usually\ntwo) distinct voltage levels -- consider these high and low\nor 0 and 1.  Contrast this with analog circuits which are\nbased on a continuously variable signal.\n\nThe typical digital circuit has (conceptually at least)\ntwo states, 0 and 1, and are designed using boolean \nalgebra (think AND, OR, NAND, NOT gates).\n\nContrast that with an analog circuit, which instead\nof interpretting "high" voltages as "1" and "low"\nvoltages as "0", interpret voltages (at least\nconceptually) as a floating point number.\n\nThe circuits have very different characteristics.\nAn analog signal often has some amount of signal\nloss (think of the "hiss" from old analog phonograph\nrecords), but they degrade gradually (ie. they\nslowly get more and more noisy, but can often\nstill operate even with significant signal loss).\nA digital circuit, however, will typically have\n*no* noise because they often have error correction\nbuilt in to handle up to some threshold of signal\nloss.  However, at some point, rather than degrading\ngradually, they just fail.  Consider the difference\nbetween the older-style cell phones (which would\nsometimes get a little "noisy") vs. current digital\nsignal cell phones which are usually crystal clear\nuntil they just "cut out".  That's a common signature\nof digital vs. analog processing.\n\nFor more discussion, see the wikipedia entries for\nboth "digital circuits" and "analog circuits".

Mathematics makes significant contributions to IT, supporting the development of both hardware and software systems. Some examples of maths that have specific application to IT (in a digital as opposed to analogue computer) are:\n\nBoolean logic:\n\nThis is a system of mathematics based around the binary states True and False (represented typically as non zero and zero). A number of basic logical operations are defined from which infinitely more complex logical rules can be built. These operations are defined in terms of inputs and outputs, and the effects can be shown by truth tables. The basic logical operations are:\n    NOT (negation)\n         Input    Output\n             T          F\n             F          T\n     OR (either or both inputs may be True)\n         Input1  Input2   Output\n             T           F          T\n             F           T          T\n             T           T          T\n             F           F          F\n     AND (both inputs must be true)\n         Input1  Input2   Output\n             T          T           T\n             T          F           F\n             F          T           F\n             F          F           F\n     XOR (one and only one input is true)\n          Input1  Input2   Output\n             T          T           F\n             T          F           T\n             F          T           T\n             F          F           F\n\nThe application of this to IT may not be immediately apparent, but this system of logic underpins both the design of the microprocessor in modern personal computers and the means to implement decision making in programming. Rules such as the following can be constructed:\n\nIf (AuthorAlive = True) AND (AuthorNotPaidEnough = True) Then GiveAuthorPayRise\n\nBinary representation:\n\nBinary is a system of mathematics based around the presence of only 2 numbers, 0 and 1. Where we have a tens column in decimal, this becomes a twos column in binary, the hundreds column becomes a fours column, the thousands column and eights column, and so on. Both processing and data storage devices in a digital computer work on a binary system at the lowest level and this has important ramifications for the capabilities of the computer.\n\nWe frequently refer to a single binary digit as a bit. Ultimately all bandwidth and data storage capacities are measured in bits, because this is the fundamental unit a computer works on. The internal limitations of a computer are derived from properties of binary mathematics.\n\nThe reason that a digital computer is built on base 2 representation is that it is much easier to construct systems with 2 stable states as opposed to more. This can correspond to the presence or absence of voltage, a north versus south pole magnetic field, a True or False boolean value in a logic gate and so on.\n\nAdditionally:\n\nThere are a lot of mathematical problems or modelling that are represented using computers. The very early origins of the computer were heavily driven by their application as calculating machines (to calculate the trajectory of artillery shells, for instance).\n\nAlso, as with any modern engineering, the field of mathematics heavily underpins IT at the physical level, through physics. We could not design a modern computer without the application of a lot of physics and therefore Maths.\n\nTherefore, this really is a very open wide ranging question.

Sure when you programm hardware drivers or program who uses the interface to any device driver. Anything is possible, it's digital... zero or one. When it won't work this way, there is another.\n\nhttp://www.programmersheaven.com/zone7/index.htm

I would say hardware. Hardware is the technical stuff that lets the software work. Like, a cd player: The actual player is the hardware but the software plays on it. You can't play the software without the hardware. With things like computers it's the same way. Anyone can make a plastic or metal machine but if you want it to do something fancy you have to have software to put in it. And if you just have software but nothing to read it or carry out the commands, you'll get nowhere as well. I could own this computer I'm on right now but if they didn't have the software for me to download internet explorer, I wouldn't be here right now. Make sense?

Metal Oxide Semiconductor Field Effect Transistor.  It's the basic component of most electronic circuits and all digital ones.  It's the breakthrough that made computers so cheap, small and popular.  A transistor, you know, acts as an electrical "gate," acting on a smaller input voltage to allow a larger voltage to pass through.  So a transistor can act as an amplifier, by using a smaller current to control a larger current.  Used in a circuit called a "flip-flop," it makes up the basic circuit for computers and other digital electronics.\n\nThere are many kinds of transistors, dating all the way back to vacuum tubes; the reason MOSFETs are such a big deal is because they are made by "printing," in huge quantities and on extremely small scales, directly onto microchips.

A device driver, or a software driver is a specific type of computer software, typically developed to allow interaction with hardware devices. Typically this constitutes an interface for communicating with the device, through the specific computer bus or communications subsystem that the hardware is connected to, providing commands to and/or receiving data from the device, and on the other end, the requisite interfaces to the operating system and software applications. Often called a driver for short, it is a specialized hardware dependent computer program which is also operating system specific that enables another program, typically an operating system or applications software package or computer program running under the operating system kernel, to interact transparently with a hardware device, and usually provides the requisite interrupt handling necessary for any necessary asynchronous time-dependent hardware interfacing needs.
