What state are cmos setting usually placed after a bios update?
To the contrary, it depends on the motherboard. For example, with Gigabyte motherboards, the current settings can be maintained even during a flash update of the BIOS. This is probably accomplished by virtue of the fact that unlike most other manufacturers, Gigabyte uses two BIOS chips on the board so that in case one goes bad or a flash update goes awry, the backup will either take over and operate the machine or it will erase and repopulated the primary with a copy of itself to get the machine restored to proper operation.
So, if you use Gigabyte and select the option to keep the settings, it will do so. With other manufacturers, Idisjunction is correct that the BIOS will most often be set back to defaults, thus requiring you to go back into the BIOS to make whatever settings changes you had before to get things back to normal.

If a PC does not boot properly and you hear a single beep then the problem is?
I would check the two power cables in the motherboard or I would check the display. Another thing to do is clear the CMOS on the motherboard, that may fix it. FYI What is "doesn't boot properly" these are answers if you don't see anything on the monitor.

- The computer displays an "Invalid Boot Disk" error after POST
- The computer displays a "Missing NTLDR" error after POST
What are the advantages and disadvantages of hiding the underlying complexity of hardware?
One of the advantages of hiding the underlying complexity of hardware is that computer programmers can create programs faster and more easily. The disadvantage of this is that programs take longer to execute due to the required translation.

It's a type of computer cable where some of the strands inside are "crossed over" compared to a "straight through" cable. You only need a crossover cable if you are connecting a computer directly to another computer. If you are connecting a computer to any other device like a switch, or a router, then you use a straight through cable, which are easier to find and cheaper. You can google for a crossover cable and it will show you a picture of which pins are crossed over.
What are the basic functions of a power cable?
To provide power from a power source to some piece of equipment or tool.
The basic and sole purpose of a power cable is to transport electrical energy from the source of the electricity to the device, example; Computer, Computer Monitor

What are the funtions of the f1 -f12 keys on a computer?
The F keys are function keys. They perform different functions in different programs. F1 is used as the "Help" key throughout Microsoft Windows and Office programs. F3 will start a search feature. In the old days (that would be the 1980's and 90's), the function keys would activate menus or other shortcuts. Some programs came with a cardboard template that surrounded the F keys to identify what function each key performed.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
What is a PCI simple communications controller used for?

Input - Devices which the user uses to enter data into the computer
Output - Devices which the user uses to retrieve data from the computer
Storage - Devices which the computer uses to store data

Do british DVDs and cds work on American DVD players and CD players?
No. They have different TV formats. The US use NTSC and our TV's are PAL.
The only way to get around this is to either copy the DVD to your computer and re-burn it in NTSC format; or make sure that the DVD player is Multi-region.
Processor in Personal computer can be called Central Processing Unit[CPU]which acts like the brain of of the computer.
It contrals,operates and does all the work governing the computer.
What is the function of condenser microphone?
The one thing you need to know when using a condenser microphone rather than a dynamic mic is that the condenser needs something called phantom power. This is a small charge of 48v that powers the microphone. Thsi charge comes generally from the mixer, which is usually either a button on or by the channell inputs, or a switch by the power switch. Also if your mixer does not have phantom power, or you are trying to hook up the mic directly to something like a a computer. you can buy an external phantom power source. Usually some sort of box.
More and more these days, users of portable electronic devices are storing data on portable memory sources. This is true especially for users of mobile phones, portable global positioning system (GPS) devices, and video and audio players and recorders. One of the primary formats for these portable memory sources is a microSD card.
A microSD card is one of the smallest flash memory cards on the market today. It is manufactured by SanDisk, which lends the SD to the name. The other part of the name comes from the tiny size of the card.
SanDisk originally manufactured the SD card, which was a bit larger than the microSD card. Then came the miniSD card, which was a bit smaller. Finally came the microSD card, the smallest of them all.
As its name suggests, a microSD card is tiny. Most technical measurements for the microSDcard put it at 15x11x1. That's millimeters, of course, and the card is roughly the size of a fingernail. In the race to store more information in less space, the microSD card is at the head of the class.
How many gigahertz in 320 gigabytes?
The two terms apply to entirely different things. Gigahertz is a measure of speed, 1 gigahertz = 1 billion CPU clock cycles per second, a gigabyte is storage space and is equal to a billion bytes
Is the most complicated component in a computer?
The CPU is arguably the most complicated component inside of a computer, with modern processors having over 2 billion transistors stuffed into the space of an over-sized postage stamp, although some video cards are also approaching that level of complexity as well.
How do you reboot acer aspire 5100?
Assuming that you can't do it from windows by going to start-->shut down-->restart-->ok, you should be able to reboot it by holding down the power button for about 10-20 seconds.. That should cause it to turn off. Then just turn it back on.
