Smart phones and tablets are computers not cell phones?

False - because they can be both.

A logically equivalent statement is:

a) Smart phones & tablets are computers AND b) smart phones and tablets are NOT cell phones.

To be a true statement both statements must be true. Since the statement "smart pones and tablets are not cell phones" is not true, the full statement must be False.

Smart phones and tablets are computers.

Smart phones are ALSO cell phones - they just have to also be computers in order to provide the additional functionality that makes them a "smart phone". Being one does not preclude them also being something else. Many people also use their smart phones as flashlights - which doesn't mean they are not also phones and computers.

Some larger cell phones are classified as "tablets" to distinguish them from the more diminutive versions of the same product - so especially in this case those tablets are BOTH computers AND cell phones.

Why people use computer?

Because they have to People use computers as they make their jobs easier.

How do you make the words bigger on the computer?

Change the display properties to use a larger font size. Windows defaults to the smaller font, but you can choose medium or larger if you find it hard to read text. In Windows 7, right-click the desktop and click Personalise, then click Display in the lower left (in the See also section). This primarily affects common user-interface objects, such as title bars, button text and all the standard text controls. Most programs will conform to the chosen size, however not all programs fully support it, or are not engineered to handle it correctly.

Some browsers, such as Firefox, allow you to simply hit ctrl-plus (+) to increase the font for viewing and ctrl-minus (-) to decrease it. ctrl-plus (0) restores the original size. This only applies to web pages viewed in the browser, however. Note that the (+) and (-) are not the ones on the numeric keypad, but the ones on the top row above the letter keys.

Where a program permits it you can also adjust the font sizes used by that program. Check the program's options or preferences for fonts and appearance options. In cases where resizing the fonts is not possible, use the Magnifier tool (an accessibility tool, or ease-of-use tool). This temporarily enlarges a portion of the screen just as if you passed a magnifying glass over the text.

When all else fails, lowering the resolution of your monitor will increase the text size.

Where can one find a deal on a backlit keyboard for a computer?

A modem performs this function. A modem converts digital information to analog information to transmit a signal over phone lines. The process of converting this signal in this manner is modulation.

Is it hard to download pictures from your digital camera to your computer?

most likely you do. It depends on the computer if it'll let you download the pics to your computer. Most computers will let you. But the only way I know of is to download the software onto the computer first. You should have a disk or floppy disk that comes with the digital camera and install it on the computer. That's all I can help with.

How are computers able to predict the outcome of an election soon after the polls close but before all the votes have been counted?

Computers can predict the outcome of an election after the polls close but before all the votes are counted by using statistical models and algorithms. These models take into account various factors such as early voting data, exit polls, and historical voting patterns to estimate the final results of the election.

The accuracy of these predictions depends on the quality and quantity of the data available, as well as the complexity of the statistical models used. In some cases, the predictions may be very close to the final result, while in other cases they may be less accurate.

It's important to note that these predictions are just that - predictions - and are not always 100% accurate. Final election results can be influenced by a variety of factors, including unexpected changes in voter behavior and last-minute campaign efforts.

Overall, the use of computer models to predict election outcomes is a common practice in modern politics, and can provide valuable insights into the potential outcome of an election.
