Can you play xbox 360 games on your PC?

No, it's impossible. Xbox 360 games are made for the Xbox 360, not PC. They both have very different hardware infrastructure, so software made for 360 would not be compatible.

It may be possible in the future, as PCs become faster though. You may have heard of emulators that run NES games - they get away with this because modern PCs are fast enough to emulate the hardware of those old systems. Xbox 360 is not old, immensly faster than NES, and millions of times more complex. If it were possible to emulate Xbox 360 it would most likely take years of work and research and only run on the top supercomputers of today.

Why CE transistor is more temperature senstive than CB transistor?

In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.

Are monitor power cable and CPU power cable both same?

Just about every computer (cpu) uses a standard IBM power cord. Most monitors do as well, unless the power cord is permanently connected.

Most computer equipment, other than printers and small devices, use the IBM power cord.

What does an LM741 micro chip do?

An LM741 is what is known as an "Operational Amplifier", or "Op-Amp" for short. Op-Amps are arguably one of the most useful electronic devices, with almost any electronic device containing at least one in some form or another.

Exactly what an Op-Amp does depends on the circuit it is in, however in general, an Op-Amp takes an input signal and boots it up to a higher level. One application would be a microphone pre-amp, where an Op-Amp would take the low-voltage input from the microphone and boot it up to a level that the power amp can use.

Why a super computer is the same as a mainframe computer?

It is not. The fastest super computers are typically much smaller physically than mainframe computers to keep signal paths short and processing speeds fast. A signal can not travel more than 1 foot in a wire in 1 nanosecond and modern super computers can do many many instructions in that time. Long wire runs limit the processing speed of any computer and must be avoided in super computers, they don't much matter in typical mainframes. Super computer designers often use extreme packaging technologies and cooling systems not used by other computers to do this.

Where are the Serial Ports located in a computer?

at the back of the cpu, it looks close to a socket of the connector to your monitor, just that it has a different number ofpins.

What are Input and Output legacy devices?

Types of devices that are not Plug & Play (plugging in a device without installing software for it first) compatible. Usually a outdated device.

Is a cipher on the back of the declaration of indipendec?

no there is not it was just on the movie national treasure there is no map on the back of declaration of independenced

How can check a transistor with digital multimeter?

If your multimeter has a transistor check (hfe), then place the Collector,Base& Emitter in the CBE port of multimeter.

Turn the shaft to Diode mode.

If the value is zero,skip that transistor.

You can use the forward resistance of each junction, using the ohms range or diode check function.

Put the leads on the Base and Emitter, then reverse the leads. You should get about 600Ohms forward bias and open circuit (infinity) reverse bias.

Do the same between the Base and Collector. You should get the same results.

Finally put the leads between the Collector and Emitter. You should get open circuit both ways around.

Be aware that some high power transistors have a diode across the Emitter and Collector.

These tests will just be a basic 'go - no go' test. It may pass this test and yet still not perform fully.

You can see obvious faults, like a dead short both ways on each junction or across the Emitter to Collector.

Should briefly holding down the power button of a laptop instead of releasing it quickly cause it to quit booting and shut off?

depends how far into boot it is, if its at the bios one small should do it, if its loading windows it will require you to hold it briefly.

Will a PC run without a graphics card?

Yes, but if there is no on board graphics, there will be no video, but yes, the computer will still run.

Actually, many PCs will NOT run without some sort of video display device. The BIOS expects a video card, and failure to locate one will cause the system to fail POST and refused to boot.

Some PCs (mostly servers) have a specialized BIOS that avoids this problem, and instead outputs the display via a serial port or (more commonly now) a specialized Management Controller chip. These systems no longer need any sort of video card to boot.

What would you need to record your voice and possibly some background music on the computer so CDs could be burned with that recording?

Its hard work. I used "My Sound Studio" and a Radio Shack microphone. The mic is good until the on button breaks. Until then, the quality is good. I redorded a full Christmas CD. It took me 72 solid hours spread over a month.

Depending on the quality of the sound card, a simple microphone might be adequate with suitable software.

But in most cases better convenience and sound quality can be obtained by using one of the many portable MP3 audio devices now on the market; most of these connect to the computer with a USB cable. It is important to pick one that has a microphone at least (some only support playing audio files transferred FROM the computer, but for this purpose one needs to transfer data from the device TO the computer). Some models also support connecting "line-level" signals from just about any audio device; this is often much better because then high-quality audio components can be used instead of the tiny microphone in the MP3 gadget.

Look around in a local computer or electronics store; devices that support capturing audio from a line-level input currently can be found for a little more than 100 US dollars.

Try a Tascam US224. You can find it at any major music store. It's both a soundcard (which is exellent for music recording like live plug-in instruments and mics) and a 4 channel mixer. It's basically an iterface between mics, midi and regular instruments and your computer. You'll also need recording software and as far as I know it comes with a pretty decent program called Cubase so that's all you need. It's also pretty inexpensive, check it out at www.tascam.com

Good luck.

Hello, i am listing my method here, i just give you an example, you can have a look at how it works for you.

How do you free up disk space in windows 7?

A good way to free up disk space is to run the windows disk clean up utility by going to "start" and in the search bar type in disk cleanup. Run it and delete all of the files it asks you want to delete. Also you can run the Disk Defragmenter utility to move files around to better places on your computer. I would suggest to download CCleaner to clean the computer.

Is there a set of keyboard keys that switch to another tab without closing the one your in?

For windows press and hold windows & tab keys together; to switch to another window press and release tab

Is there a way to force close a com port on windows?

If you are referring to a communication port, then you can find the program that uses the port and shut it down. You can look under services and find the program and force it to

stop/disable.

Zone alarm firewall, has a great program watcher. This will see all the programs and it will allow you to stop them from connection the the internet, yes even windows programs.

You can stop windows from phoning home.

What is difference between USB host and USB otg?

The difference between a USB host and USB OTG is simple. USB host is one device connected directly to the computer. USB OTG (on-the-go) is where a device, be it a cellphone, tablet, or whatnot is connected and used as the host.

What type of microprocessor contains 42000000 transitors in the same thumbnail sized piece of silicon?

A Pentium 4 contains 42 million transistors. Forty-two million transistors isn't very many--the highest-end Itaniums and Xeons have nearly two BILLION transistors.

What do you do when you plug your ipod into your usb port your ipod lights up but is not connecting you have tried resetting different ports and cords and restarting your computer?

Try entering DFU mode/recovery mode. For ipod touch and iphone only. Take iphone as ipod, it's the same procedure.

Step One
Open iTunes and connect the iPhone to your Mac.


Step Two
Press and hold the Home button and the Sleep/Wake button at the same time.


Step Three
After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.


The iPhone screen will remain black like this:


NOTE***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long!

So if u did that properly, you get it and restore the ipod. Then it should work. If not contact apple.

Does an r4 card need an USB reader?

Yes because the micro SD needs to be plugged into the USB reader so the computer can read the SD and so you can put your games onto it.
