What is that buzzing sund that comes from the black box in a laptop power cord?
The buzzing is probably the capacitors and other components transforming the electric current coming from the wall to a volt, watt, amp, ect...that your laptop can use best. If it weren't for the transformer box on the cable, we'd only need a long piece of wire to run our laptops. But computer companies have designed their laptops to use different ampherage voltage, and wattage as compared to your standard electrical current for battery and charging efficiency, as well as a small way to add more money onto the price tag. It's not a big problem, its just your cable doing its job
What are the examples of ergonomics hazard?
Ergonomics can be defined as the "law of work". The approach is to
fit the job to the worker, not the other way around. It's about how
much people are expected to do with their bodies and brains. As a
Canadian ergonomist says, workers are expected to do things on the
job that robots don't do.
When an ergonomic approach is not used to design work activities,
tools and/or equipment, you may be exposed to (your body comes
in contact with or must deal with) a variety of problems. The odds
are that you will end up with "aches and pains", "strains and
sprains", musculoskeletal injuries (MSIs) -- whatever you call it, it's a
lot of pain.
How do you convert a 4.15 megabyte picture to a 30 kilobyte picture?
Yes, try changing the format of the picture. Eg. from .PNG to .JPG or 32-bit BMP to 16-bit (although reducing the size or changing formats may convert the image to a poorer quality).
How do you install a firewire card on your computer?
1) Turn off your computer
2) Open the computer (slide off the side panel).
3) Locate the empty PCI slot (usually white and at the end of the motherboard).
4) Insert the Firewire Card into the white PCI slot (line up prongs and push gently).
5) Fasten the card to the computer frame using a single screw to secure card.
6) Slide the side panel on again.
7) Turn on computer.
8) You can now connect your camcorder to the firewire port (use proper cable). Then you go to your couch and sit on it and press the on button and see if it works from there if it dose then go and watch sponge bob ( the person who write the thing that is above is write I am wrong HE He He)
What does Twain stand for when talking about image scanners?
I think it stands for: TWAIN; The Way An Image Negotiates or is negotiable. To negotiate or communicate with other programs!
TWAIN has no acronym. The popular story behind the most common answer, is that while being pressed for an answer as to what it stood for, one of the people responsible for the creation of TWAIN, quipped "Technology Without An Interesting Name". However, there is no real meaning to it, it is just TWAIN.

What is the GPA requirement for Radford University?
You need about a 3.13 to enroll at Radford University. Great school.
Why do computers require their own internal Power Supply?
Computers require their own internal power supply because the power required to power most newer computers, especially with high-end graphics cards, would require a bulky power supply which wouldn't be ideal in transporting computers or aesthetically.
Also, with all of the other internal parts of a computer, some type of power interface would be necessary within the PC anyway, so why not just bundle it all together?
Why does CAD require powerful hardware to run the software?
CADD requires high processing speeds because of the thousands of calculations that it is required to do every second.
If you are using 3D CADD software, such as SolidWorks, it must be able to take integrals and all of the other calculus based equations for a full model.
This is why when you make one simple change to the beginning of a SolidWorks drawing once you have finished, or come close to finishing, the part it must redo every calculation that it had done the entire time that you were working on the model checking for places where any errors would occur and reshaping the part from start to finish.
What does the -R mean on a DVD?
Once you write anything on DVD you can view, but you cannot re-write on the same dvd. So, it is DVD-R not DVD-RW
What are the best video cards upgrade for emachine W3650 With windows 7 ult 64 bit?
Your motherboard is running a PCI-Express x16 1.0 port (The orange one at the top), and therefore is able to grant you a few more graphics card options than even a slightly older computer could offer-- Be warned, this is still a legacy technology so your upgrade route is limited.
I don't suggest going any higher than the nVidia 560 (Or equivilent part) due to bottlenecking at the motherboard level, as well as potential power requirements that your power supply may not be able to handle. You can buy any card on the market for PCI-Express x16 and it will fit in your slot, but they will be more and more heavily gimped by the slower 1.0 bus speed as the cards get more and more powerful.
I suggest a new computer, really.
Is a surge protector used for electrical fouls?
a surge suppressor or protector protects your equipment from spikes on the electrical line.
A small amount (normally less than 1MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.
AnswerA cache, in computer terms, is a place to store information that's faster than the place where the information is usually stored. Cache memory is fast memory that is used to hold the most recently accessed data in slower main memory. The idea is that frequently accessed data will stay in cache, which allows the CPU to access it more quickly, which means it doesn't have to wait for the data to arrive.
In reference to your processor, the Cache Memory is the Processor's internal quick-hand storage that it uses for things that it's currently processing at that given time.
As with most things, the more cache memory a processor has, it will usually run smoother and faster than one with less of about the same operating frequency.
Answer- Cache memory is usually "On Die" which means it is in the processor chip, which allows it to 'talk' with the processor direct at a much higher speed than standard RAM.
- cache is a small chip, that's usually placed inside the CPU or sometimes its right next to it and is responsible for providing direct access to the commonly used programs, rather than going back to the hard disk and ram again and again
so cache makes it more fast than RAM, you know!!!
Pronounced cash, a special high-speed storagemechanism. It can be either a reserved section ofmain memory or an independent high-speed storage device. Two types of caching are commonly used inpersonal computers: memory caching and disk caching.
A memory cache, sometimes called a cache store orRAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because mostprograms access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.
Some memory caches are built into the architectureof microprocessors. The Intel 80486 microprocessor, for example, contains an 8K memory cache, and the Pentium has a 16K cache. Such internal caches are often called Level 1 (L1) caches. Most modern PCs also come with external cache memory, called Level 2 (L2) caches. These caches sit between the CPU and the DRAM. Like L1 caches, L2 caches are composed of SRAM but they are much larger.

ANSWER
I would like to point out the disadvantage of the Cache...Just in case the Cache memory is full and data that is required to process or an application required to run doesn't fit into the Principle of Locality (that is not in the near by location) then it is obvious that the time required for the main memory to access the information would increase...coz first the the data need to be relocated into the cache and then process over here if the cache memory was missing it would be quicker...furthermore being such an extensive memories they are very small in Memory Size which requires location and relocation of the data or applications.
It allows commonly accessed data to be stored in full and referenced faster than recompiling the data each time.
What type of system software are USB flash drives compatible with?
Flash drives are compatible with all types of computers, but the computer must download the driver software from the internet, which may take all of a few seconds, to use the flash drive.
If you are trying to access a Windows partition on your hard drive, this is not easily possible from DOS. DOS can only read FAT partitions, while modern versions of Windows typically use NTFS. Also, DOS cannot access hard drives on a SATA controller unless the controller is set to "Legacy" or emulation mode.
What is the meaning of DVD plus R and DVD minus R on a DVD disc I purchased?
The + and - denotes the way data is stored on this disc. There is no difference in quality, but older recorders and DVD players may not be able to recognize or properly access one of these formats, depending on the manufacturer of the drive or blank disc.
that particular field failing indicates potential impending media failure in the drive. the only thing that can be done to correct it is immediately purchase a replacement drive and copy the entire old disk to the new disk before the media completely fails.
What is computer repair and maintenance?
Is a set of service or procedures performed to keep a computer in good working conditions
They do sell plexy glass or plastic casings that computers can fit into with keylocks and a few fans built in they usally sell them at compusa or micro center they are not cheap but they work. usally made or ITs
