Differences between 115 volt and 120 volt?
These are different ways of measuring voltages. In the united states, people often refer to the standard household electricity as "110 volt", because that is close to the average voltage over time that the sine wave will be at. 115 is was MOST electric companies actually produce, on average, and 120 volt is the RMS measurement of that voltage. The peak voltage at the top and bottom of the sine wave will usually be close to 125 volts. For more information, please google for how AC works.

How many gigabytes in 6250 megabytes?
1 gigabyte = 1024 megabytes. In order to find out how many gigabytes 2250 megabytes is equal to, we must divide 2250 megabytes by 1024 megabytes ( 2250/1024 ). This way we find that 2250 megabytes = 2.197265625 gigabytes.
How do you install window vista basic on Acer aspire m1640 model?
Download the SATA drivers from the Acer website. Extract the files onto a FLOPPY DISKETTE Open the acer and connect a floppy drive to the motherboard and the power supply (Fortunatly Acer have still left these connectors available) Start to install the Vista on the Acer. When it requires a driver for the CD/DVD player, go and look on the floppy disk. All should then be fine
What to do when a usb port on motherboard is failing?
The key to this question is that it is "a port" not all the ports. Updating the BIOS is not likely the best answer. The book this question comes from actually has the answer but many people are not finding it because it is in a blue box. The answer is to disable the port in the BIOS or by jumper and add an expansion card.
<Old answer> upgrade the BIOS or download the latest drivers
Where can one purchase a dual CPU motherboard?
One can find a cheap dual processor motherboard on Amazon, Ebay, Craigs List, Kijji and perhaps in Computer Stores. Other places to find a cheap dual processor motherboard is using another computer's parts, perhaps one that is sitting that is not being used.
Why can objects heavier than water float in water?
A metal boat, on its own metal would sink but in the form of a boat-with the overall mass spread out and pockets of air making up most of the interiors- will not sink.
It isn't really a question of density it is a question of construction.
What the speed for hi speed USB?
Up to 480Mbits/second, and being increased over time with improvements.
There are 1024 gigabytes in a terabyte
And 1024 terabytes in a petabyte
So there are 10242 or 1 048 676 gigabytes in 1 petabyte.
Interesting side note: It is said that google processes 20 petabytes of data every day.
What is the purpose of a video capture card?
Since most computers cannot natively grab video from an external source, like cable, a DVD player or camcorder, a capture card gives it that capability. Once the raw footage is stored on your hard drive then you can use the video editing software to make changes to it.
Is single core processor will support multi threaded program?
Of course it will run. But it will not be making full utilization of the multi-core architecture. In that aspect, single-core processors with more processing power are sometimes better suited to run single threaded application than multi-core processors with less processing power.
What is the difference between BIOS and device driver?
In IBM PC compatible computers, the basic input/output system (BIOS), also known as the System BIOS or ROM BIOS , is a de facto standard defining a firmware interface.
When in computing, a device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.
What color or stripe down one side of a cable marks this side of the cable as pin 1?
Usually an arrow pointing to it, or a number 1 on the connector. It's also on the side with the red wire. And most boards are keyed with a slot on the side of the female part, and extrusion on the male connector... so it can only be inserted the proper way.
What is the importance of recording bios and motherboard information correctly?
so you can connect the cables of the components attached to the motherboard in order for the PC to work correctly. For example. The turn on button cables go in an specific set of pins in the mother board. If you don't record the specific pinns for that you will not be able to turn on that assembled PC. So information should be properly recorded.
Why won't computer recognize video card?
Have you installed it correctly?
What hardware are you connecting?
The device may need a 'driver' which most likely came on a CD with the device.
If there is no CD, try looking for a download from the device manufacturer's website. Have you installed it correctly?

the formatted capacity is always different (and less) from the discs stated capacity, so heres a chart based on 1 gb = 1024mb
4.7gb DVD = unformatted: approx 4812mb formatted: 4392.96mb
Can you add memory to a laptop?
Yes you can easily increase RAM of your laptop. First you need to find compatible memory type for your laptop. It will depend on the laptop configuration (like chipset). Most laptops made in last 3-4 years have DDR2 SODIMM memory type. You can also use some of the free utilities like cpuz from cpuid.com to find exact chipset, type of memory installed including size, speed etc. installed in your computer currently in each slot. Before you buy the memory you can once open the memory area cover from base side of the laptop to have a look at the memory slots. This will give you confidence that once you have new modules with you will be able to open up the unit and install the modules.
What is the significance of the multi-session feature on a CD drive?
That the drive can read a disc that has been created in multiple sessions. To say a disc was created multisession means that data was written to the disc at different times rather than a single long session.
What describes a collection of hardware components that function together as a system?
Do you want a software to collect the computer‘s hardware information from LAN ？
What measurement is commonly associated with computer processing speed?
- Hertz (MHz, GHz)
- hertz (Hz) as a unit is defined as the number of cycles per second, making 1 megahertz (MHz) one million cycles per second, while 1 gigahertz is 10^9 hertz. Vibrations and electromagnetic radiation are measured in hertz units, but in computing it is the clock speed of the central processing unit that is referenced in terms of hertz. CPU
- In the broadest terminology, a CPU or processor is the element of a computer that carries out received programming. The CPU is usually an integrated circuit called a microprocessor which carries out the functions of retrieving, decoding, carrying out, and writing back (providing further instruction). This process is one cycle, measured in terms of the computer's clock speed. Clock speed
- A crystal oscillator, a vibrating metal crystal which is another circuit in a computer, provides a signal (clock signal) which determines the computer's clock speed (or rate), that is, the speed at which a CPU completes one cycle. Thus, a CPU at 1 GHz is completing 1 billion cycles per second (carrying out 1 billion programming instructions). In computing, it is very important that this signal remain precisely constant. Comparisons
- Because of variances in the ways in which different machines and processors execute operations, it is not always possible for the casual user to tell ahead of time which type of machine and processor will perform a task the most quickly. This means that using the clock speed (Hz measurement) of a system will not always indicate how quickly that system will perform a task in relationship to other systems.
Hope be helpful!
