Computer Memory

•A portable device, is a device that is lightweight and small so you can use at home as well as outside; for example you can use it for business travels, like you can take a laptop, a tablet or your mobile phone with you on your work journeys.

Originally they're kept on the hard drive in the form of a program. Once run, the instructions and data are loaded into main memory until the processor is ready for them. They are then read into the various levels of CPU cache when awaiting execution.

Yep. If you reformat you hard dive, every thing is deleted.

A motherboard is the main printed circuit board found in computers. It holds many of the electronic components of the system such as the central processing unit, memory, and provides connectors for other devices.

Providing that you maintain the same voltage and above all, make sure that the polarities are the same, yes, it should work. It's OK to have a little more power available than the device requires but it shouldn't be less, which can cause the cable to over heat or cause undue stress on the device itself. It sounds as though you're using a wall adapter to run something, and the extra .5 amp capacity should be OK. But, when using a wall adapter, always try to keep as close to the rating of the device as possible. Wall adapters that provide more power than what's needed, can over heat because the extra power isn't being used. It's just being converted to heat. Since you're within 20 percent of the device's ratings, this shouldn't be a problem.

The reason you should have your computer at the right height is so things will be comfortable for you. It is beneficial to your health if you are in a comfortable, well-supported position. That way, you are less likely to injure your hands or back, and less likely to injure your eyes.

Spyware is stored in various places. Like the registry,files,bookmarks,favourites (user area).There could be memory resident spyware too.

Registers

Which standard format? There has got to be over 10,000 of them.

There is a hardware protection on the card itself. It's a little slider on the side. One way is protected, the other is not. Typically, having the slider up, towards the contact side of the card, is unprotected.

When you try to boot the system, you will get a POST error message and will not be able to boot.

If someone programmed a computer to write everything to the hard drive, then yes it might work but it would be...really...slow and the life span of the hard drive would be significantly decreased. However, if you just took the RAM out of your computer right now, your computer would refuse to work and wouldn't even start up. Compare it to like a person trying to function without short-term memory. We'd have to memorise it, process it, then try and erase it from memory or have it buzzing around in our head for the rest of our life. With RAM/short-term memory, it could just go in one ear, get processed, then go straight out the other ear.

Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.

The number of bytes used by a character varies from language to language. Java uses a 16-bit (two-byte) character so that it can represent many non-Latin characters in the Unicode character set.

List three kinds of memory modules? DIMM (dual inline memory), RIMM (random inline memory), and SIMM (single inline memory)

yes yes yes yes yes

A small light bulb is often used to test a solid state relay (SSR). That is because a SSR needs a minimum load of at least 0.1 amps in order to operate. Using a meter does not provide a sufficient load.

Bit, short for Binary Digit.

There are plenty different reasons why your computer to freeze. But the most common 2 I will say. Well my brothers computer likes to freeze sometimes because it gets too hot, and plenty other computers like to freeze, and when they do, it might be for this reason. Or the other reason is the complete opposite, having a crappy computer other than have one to powerful, it can't take the heat. Well my computer likes to freeze because it's a crappy computer and when I'm doing a million stuff at a time and it's trying to load too much at once, it'll freeze. And these are the 2 main problems with a freezing computer. To check the tempurature, google something up and you'll get something. Hoping I was most helpful.

here, just the registers are used to store the temporary data in the variables instead of RAM.

768 MB RAM is good for Windows XP only. If you want the more recent Vista or 7, maybe try upgrading to at least 1 GB.

Food coloring works by absorbing and reflecting different wavelengths of light. The molecules in the food coloring interact with light to give the appearance of a specific color. Different food coloring molecules absorb different colors of light, which determines the color we see.

Try starting your computer in safe mode by pressing the F8 key at the beginning of the start up. Keep pressing it until it gives you the option to enter safe mode. From there you should be able to fix the problem.

It is faster to access RAM than the Hard Drive in a computer, this is why lots of RAM is good, as the computer can store more data on it that is being used so it can be accessed and thus run faster.
