Ati mobility radeon HD 5470 vs nvidia geforce gt 320m?
Generally the 320M should outperform the HD 5470. Neither can play the more demanding games on anything else than maybe low to medium graphic settings.
The only major advantage of the HD 5470 would be it's DX11 support (vs 10.1 on the 320M), which still isn't such a big deal since it probably won't be able to play DX11 games on a level of detail where it would mater.
In short, both can be used to play lighter games as well as high definition video and Internet browsing.
No.
The definition of life is a little wobbley, some things you may think of as alive are not for example viruses. Computers are sensitive and respond to stimuli, they require nutrition in the form of electrical energy, some can move. But none of them meet the definition of life.
To be "alive" a computer would have to be capable of reproduction, excreation of waste products and growth.
If you had a computer which could build new bits onto itself and was linked to its own energy generating system (petrol generator) you would be getting close.
It's not really a question of how smart the computer is; bacteria are dumb but living. The problem has more to do with if a computer will ever be able to make copies of itself that could be classed as reproduction.
If a computer ever does hit all the criteria for being alive, then the criteria will probably be changed.
How do you charge mobile without charger?
you can use a equipment which converts microwave signal into electric enerry and use that electric energy to charge your cell phone. i am now doing a project to convert huge electric energy from mobile towers

Is meg the same as a megabyte?
Yes and no.
A megabyte was originally 220 bytes, as a kilobyte was 210 bytes. 220 is 1,048,576, so a megabyte was 1,048,576 bytes. In the early 1980's, though, sales people for hard drive companies decided that if they arbitrarily defined a megabyte as precisely 1,000,000 bytes, it would make their hard drives seem larger and thus would make them more likely to sell.
Today we still see that same distinction. When you are buying hard drives, they are measured in "marketing megabytes, gigabytes, and terabytes," which are precisely 1,000,000 bytes, 1,000,000,000 bytes, and 1,000,000,000,000 bytes, respectively. However, when you are talking about computer memory, or when you ask the operating system (Windows, OSX, or Linux for example) about disk space, the answer you get back will always be counted in old-style megabytes / gigabytes / terabytes. And this is why a 1.5TB hard drive that you buy will only seem to have 1.2TB when you look at it in Windows after you have installed it. The number of bytes will be the same, but a true terabyte, 240 bytes, is larger than the terabytes used to define the drive size for sale.
Continuation
A megabyte is exactly 220 bytes in binary. Decimal does not align with binary bit boundaries so the decimal equivalence of binary numbers are always off counts.

What does a vga slot look like?
VGA ports are 15-pin female display ports that are generally blue. These are found on the back of PC's (near USB ports or further away on a video card) and on display devices such as monitors/TVs. A quick image search will show you exactly what to look for.
Why does my computer turn itself off?
well it depends. Your computer might be on some energy saving program that after a while left untended it shall turn off such as energy star. Or if your computer is on the floor your foot may of hit the "off" button.
What is the function of a computer ribbon cable?
Ribbon cables in a computer are mostly used for carrying data between devices. Sometimes they are used to carry supply voltages as well, but since they are usually lightweight, they are more commonly used for carrying data and control signals. The most common use is for floppy drives and hard drives. However, they can be used for connecting between different circuit boards, such as a mezzanine card - a type of controller card that has two circuit boards. There were also likely used in older mainframe computers since they contained so many circuit boards. On older Apple computers, they were sometimes used as printer cables too.
How do you explain input and output device?
Before a computer can process your data, you need some method to
input
the data into the machine. The device you use will depend on what form this data takes (be it text, sound, artwork, etc.).
Similarly, after the computer has processed your data, you often need to produce
output
of the results. This output could be a display on the computer screen,
hardcopy
on printed pages, or even the audio playback of music you composed on the computer.
How do you locate graphics card?
Locate the connector where the CRT plugs in. If it plugs in to a separate card, that's the graphics card. If it plugs in directly to the motherboard then the graphics card is integral to the motherboard.
What happens when a USB 1.1 device is plugged into a USB 2.0 Port?
It will work, but the data transfer rate will be much slower than if a USB 2.0 connector is used. This may not be acceptable for high data-rate applications, like high definition video.
Will an 8x AGP video card work in a 4x AGP slot?
It will work, if it is compatible with the signalling voltage on the motherboard (1.5v for AGP 1x, 2x and 4x), but it will only work at up to the 4x that your motherboard is capable of. You may need to change your BIOS settings for AGP= 4x to obtain maximum performance from your motherboard and graphics card. AGP 8x cards run at 0.8v but some may permit 1.5v 4x compatibility.
Those folks experiencing problems with 8x cards in 4x slots might consider the possibility of power supply issues. It's not unusual to see newer cards requiring 300-350 watt power supplies with specific voltages requiring up to 18 amps. Many old Dells and others have only 250 watt supplies, and the new dual gizmo gazillion megahertz screamers take a lot more juice than the factory-supplied cards.
Some 8x cards are designed to be able to clock down to 4x, some are not. Many times it will say whether or not this is possible right on the box. In all respects the motherboard or 8x card should not be damaged by attempting this, the worst that will happen is it wont work.

What is handles in computer terms?
A handle is a particular kind of smart pointer. Handles are used when an application references blocks of memory or objects managed by another system, such as a database or an operating system
copied from a web site I can no longer locate.
What things do you need to be able to connect to the internet?
*Internet itself must exist
*You must be connected to your ISP using cables and/or wireless signal
*You must own a device capable of connecting to internet(with CPU and network card)
*It must have installed an operating system supporting TCP/IP(Microsoft Windows or GNU/Linux for example)
*Network connection must be properly configured in your OS.
Which computer component presents the most danger from electrical shock?
The computer component that presents the most risk of electric shock is the power supply. Since there are large capacitors in the power supply, it is possible that you might get shocked, even with the power supply unplugged.
Another component that presents a shock risk is an internal modem. You might grab a hold of it while there is an incoming phone call, and then get shocked from the ringer current.
Yes, but it must be with one of the same type. EG, you can swap an Intel Pentium 3 1.5GHz with a Intel Pentium 3 2GHz, but not with an Intel Pentium 4 2GHz. Also, it must be the same socket type.
Is there such a thing as PCI RAM?
There is no PCI RAM, but we have a PCI card to which we can connect more that one RAMs to that PCI card
What possible Implication of Upgrade CPU for other hardware components?
Upgrading your CPU can have a huge impact, or none at all. If your CPU is causing a bottleneck in your system, due to other components being more efficient / powerful / capable of doing whatever tasks you are demanding of it, then an upgraded CPU could greatly increase the speed of your system.
However, if your CPU is more efficient / powerful / capable than other pieces of hardware (such as your GPU, harddrive, or ram), then upgrading your CPU may have little effect at all.
If you are having issues with your computer being too "slow", as I suspect you may be, then make sure that your CPU is actually the problem. When your computer is running slowly, check to see how much of your CPU is actually being used. If it is requiring 80-100% of it's capacity, then a CPU upgrade may be a good idea. If it is not, then look at your other components, and see how they are performing.
That said, the first step should always be to check for viruses, clean up your system, defrag (if you have a HDD...do NOT defrag a solid state drive), remove unnecessary programs, etc.
your best bet at the moment is either some kind of macro pad or hot key program like autohotkey. there isn't really much in advanced heuristics atm. otherwise it is some kind of touch or pen based input... unfortunately computer input methods/devices is an area of computer technology that has remained mostly stagnant since the creation of computers.
to provide a medium to expand the capabilities of the PC, by adding like modems cards, audio cards, ethernet cards.
How do you fix your HP laptop monitor that flickers?
I have the HP G71-340US Notebook (17" screen). Once dissassembled the screen has a rail assembly on both the right and left side that it mounts to. There are 4 screw holes on each rail but the computer only comes with 2 screws on each rail mounting to the screen. My mistake was that I installed the top 2 screws in the top holes and the bottom 2 screws in the holes DIRECTLY ABOVE the bottom holes. There is a wiring strip that runs along the bottom of the screen and if it touches the housing it will cause interference/flicker. All I did was remove the two bottom screws and install them in the very BOTTOM holes to lift the screen off of the screen housing. No more flicker! Makes me wonder if maybe some of the laptops off of the shelves might need to be checked. A lot of issues about HP and flickering screens on google. Hope this helps.
How do you set up a computer to power back on after a power outage?
You will need to enter your computer's CMOS/BIOS settings. Usually, when the computer is first turned on, you will press delete or F2. Some computers, such as a Dell, Compaq, etc. may have different commands or not be accessible to configure.
Please be careful, as changing settings here can physically damage the computer if set incorrectly.
Sounds like some variant of SCSI but I'd have to see a photograph to be sure.
