Parallel computing is when you do a lot of different things at once, a graphics card is a parallel processor. The main CPU is a serial processor, it does one thing, but does it really fast, then switches to another. Video editing works better on a parallel processor, for you can encode different frames all at the same time, instead of working on one, then moving on to the next.

Does turning on a fan in the room help to cool a computer?

Provided that the air inside the computer case is hotter than the temperature in the room, then basically: yes, the hot air from inside the case is replaced by cooler air from the room. However the fan only moves around the air it doesn't change the air temperature so make sure you have some good AC.

A: Even if the same hot air if allow to flow on an object it will cool it. That is the answer.

Can your computer be hacked if you aren't on the internet!?

Yes. Companies like Microsoft, HP, and Norton leave holes in the computer software they produce allowing hackers to break into them over the Internet.

+++ The Internet is about the only way it can be hacked, unless the hacker has personal, physical access to a terminal on the specific system such as a company's internal network.

Most hacking is covert, some is overt by fraud. A typical ploy for the latter is to telephone unsuspecting private computer owners and say "I'm from the 'Windows Corporation' and your computer has reported a fault". Fall for it, and you end up giving the hackers remote control of your computer via the Internet.

What type of computers are found in a digital watch?

It depends on whether the digital watch has a digital display (LCD) or a standard mechanical display (a clock-face). The latter is probably simpler to understand as it is primarily an analog computer driven by a digital counter. A quartz crystal vibrates at a consistent 32,768 cycles per second thus a 15-bit digital counter increments with each cycle. Each time the counter overflows it returns to zero, which triggers a step-motor to advance the second hand by one second which, in turn, drives a standard clockwork mechanism advancing the other hands accordingly. The tumblers denoting the day are linked to the clockwork mechanism, although sometimes these are presented in a digital LCD form.

An LCD watch has no moving parts besides the vibrating crystal, thus is entirely digital, with several digital counters to denote the passage of time from a preset base time (the time you set). Simple logic gates present the actual time upon the LCD display in numerical form or in a more graphical analog clockwork form.

Computer devices that use mathematic operations?

Computers transfer everything into a simple 2-digit code. The values are either 1 or O. This is the Base 2 number system. The Base 2 Numbers is easy for computers to handle because electricity can be On or Off. The electrical current flips a magnet-type device in its memory so that it is either in a 0 state or a 1 state. This is how the memory stores anything no matter how complext the data is. Any number in the Base 10 which we use(hey we have 10 fingers) can be converted into the Base 2 numbers. The computer does this and then operates by adding or multiplying in the Base 2 and then it converts it back to Base 10 for you to understand. Counting in Base 2: 0..... 1..... 10..... 11..... 100..... 101..... 110..... 111 ..... 1000 ..... 1001 ..... 1010 ..... 1011 ..... 1100 1 ..... 2 ..... 3 ..... 4..... 5..... 6..... 7..... 8..... 9..... 10..... 11..... 12 ..... 13 I hope that is right.
