Detail Discuss the implications of the democratization of information?

An information democracy provides broad access to corporate information. Companies must avoid an "information monarchy," where only senior management has access to information, and "information communism," where everyone gets the same information but it's not really that useful and they have to wait a long time to get it.

Is a OPTICAL MOUSE an input or output?

It scans and input data into a PC. (Input device)

How do you rip DVDs onto your computer for editing?

Last,copy ripped DVDs to the iTunes library,then sync iTunes with iPod manually or automatically.

Software that helps the computer communicate with a particular device?

A "driver" is a small program which enables software to talk to hardware. Anytime you install a printer, digital camera, sound card or video card, joystick or any other peripheral, you would need to install a driver to enable both Windows, and the software which will use the hardware, to communicate to it. Windows often comes bundled with generic drivers for printers, cameras...etc, however a CD usually is packaged with the hardware which should be used.

Why is it necessary to have an MSDS on file in a computer lab?

Material Safety Data Sheets (MSDS) provide necessary information about precautions for protecting against known hazards associated with chemical materials. Hardware components contain a certain amount of toxic level and it must be handled carefully. MSDS often include useful information on chemical, physical and toxicological properties, along with suggestions for storing, transporting and disposing of chemicals.

What are different ways of inputing data to a computer?

The downloading software off the internet from a trusted site.




Other methods include:

(a) input from a keyboard or mouse
(b) a USB connection to flash drive or external memory
(c) wireless network connection

Can one user have multiple email accts on one computer?

Absolutely ! I have three email accounts - all on this computer.

What is the difference between laptop computer and super computer?

Super computers are made for extensive and intense calculations. They are built to be able to solve humanly impossible mathematical problems in mere seconds.

N.S.A has a super computer called the "Thinking Machine". It is used to break codes. It can do in a few seconds what a Home PC will take tens of thousands of years to calculate.

Regular computers are also made for calculation, but not to the extent that super computers are designed for. Most regular computers involve word processing, calculated excel documents, and financial software. The more intensive calculations would come with graphic processing as physics require a bit of muscle, and that is why we add-on graphic cards.

What role does a server play in a computer network?

A server is as the name suggests: it provides a serviceto a network of clients. In the world of the Internet today, this can range from Web servers (they run websites, including this site you're using now), game servers (these run online games where people can play with each other online), and much more.

What are you purchasing when you buy a typical computer software package?

Software, like any kind of media (DVDs, Videos, CDs, etc) is copyrighted by a publisher. When you buy media such as this you are, indeed paying for the materials involved (the box, the manual / release notes, the CD, etc), but moreover you are paying for a "license" to use the media.

Different types of license cost different amounts. If you buy a computer program that you intend to use on several computers (for business, etc) then you generally have to pay more for the license than you would if you only intended to use it personally. Anti-virus programs are a prime example, as you are forced to renew your subscription every year.

A percentage of this license fee goes to the people who produced the media, another percentage goes to those who created the media (the "artist/s") and various other percentages go to the other companies and agencies who were involved in publishing, marketing and manufacturing it.

It may seem like you are paying for thin air, but ask yourself; if you had spent hours, days, weeks or even years creating something, wouldn't you be a bit angry if someone stole it! This is why publishing companies fight software pirates so doggedly, and this is why there are laws to prevent copyright theft.

What factors should be considered when purchasing a computer system?

Age is everything. Computers are like a fine wine. They get smoother and more robust with age.

But seriously... You must look first at what software you wish to run on the computer and find out its mininum and recommended hardware requirements.

A computer has many components of which the main ones are:

Memory (RAM)

Memory (Hard drive size)

Processor (speed)

Video card

Get at least the recommended hardware to match the software requirements.

Computer which approach to acquiring a system seems to be less expensive?

Building your own PC would be the more cost efficient than buying a new preassembled PC. It will also give you the capabilities of installing what you want in to the PC you build.

What is the smartest computer?

What is the name of the two main personal computer?

Dell, Acer, HP, Apple are some computer manufacturers.

How are laptop power adapters found?

First, one would need to know the exact model of the laptop. Many different places sell laptop power adapters such as Best Buy, Office Depot and even places like Walmart and Target.

Which one is the best computer for gaming?

No one single best gaming computer exists. The best gaming computer will depend on what games you wish to play on the computer. If you are looking for the best gaming computer that you can load any game and play without a hitch, you are looking for a specialized computer built just for gaming. You can buy a machine from a best gaming computer like Velocity Micro or from Digital Storm to name a few. The other option is to build the best gaming computer yourself.

But if you're hardcore, you could spend your life savings on a double ATI 5970, together with a PSU that can produce atleast a few kilo watts. Then you should find a motherboard that allows you to insert 128 GB of RAM (which is the maximum amount of ram that windows 64 bit will allow you). Then I believe you should take on of the Intel's i7 extreme series. Then buy as many hard drives 2TB as your motherboard and PSU allow you to.

I know that a single ATI 5970 is like 600 euros, so a double will make it 1200 euros. A psu capable of producing kilowatts should be atleast 300 euros, a motherboard (if they excist) that support 128GB of RAM will surely be a couple thousand euros. The CPU will also be over the thousand euros and last you got the RAM. I have no idea how 128GB will cost. I know my 4GB ram was 100 euros. I know some people got 8 GB for 300 euros, as if the prices are exponential, but just take from me that your ram will probably cost more than your car.

Can computer work as human being?

Not entirely. Computers can do many jobs that used to require humans. This is evident everywhere from banks to online travel websites to electronic toll booths. However, computers will never fully replace human beings, because they lack the ability to think and feel, two extremely important human attributes.

What does XD D and P mean in chat?

In basic chat lingo, code names for emoticons are typed out on the keyboard.

XD, :P, :) etc stand for denoting emotions while chatting. In services like Yahoo Messenger, you already have a set of emoticons available for insertion in the text. But you can use the code names too.

Answer

Look at them sideways and you will see they are what is called "smileys" or "emoticons," as the last person who answered said, they represent different emotions.

XD is a laughing smile.

:P is face with tongue out.

:) is a smile

How does a supercomputer work?

Historically, supercomputers worked sheerly by having a more powerful processor than other types of computers. However, due to limitations inherent in processor design, they now work mainly through multiprocessing. When they are given a task, they split the task up and run it on several different processors at the same time. With multiple processors working on the task, it takes much less time to finish it. When the supercomputer needs more power, the engineers simply add more processors (often called "nodes").

Supercomputers are generally used to do simulations. The problem with computers is that they are great at discrete simulations (what happens at point x at time y given inputs z?), but they tend to suck at analogue simulations (what will happen in this area over a time period?).

You can approximate analogue simulations by doing discrete/digital simulations over thousands or millions of points of space and time. The more points you can calculate in a simulated hurricane or nuclear explosion, the closer you get to the real thing. Hence bigger and badder supercomputers can do simulations that are closer and closer to true analogue representations.

As chrismear says, the stewardship program are probably running nuclear explosion simulations with varying inputs based around the age of the stockpile and the half-lives of the component compounds in the warheads.

Rest assured that the 'safe and reliable' thing is mostly based around "will they still do as much damage as reliably as they did when we tested the real thing?". 'Safety' is not really an issue when the warheads need external detonation to get them anywhere near critical mass.

What does txt mean on a computer?

txt stands for Text. It is often used by plain text editors as the suffix to the file name. There is no formatting associated with most txt files. You should be able to open them with a word processor, notepad or wordpad on your computer.

With what can users access account balances pay bills and copy monthly transactions from a banks computer right into their personal computers?

People can access their account balances on their personal computers, by visiting their banks website. Users can log in, pay bills and view monthly statements.
