What is the job of the cooling fan and heat sink?
They're used to help keep the processor on the motherboard inside the Central Processing Unit (CPU) from overheating. Both are necessary: the fan actually protects all the devices inside the CPU from overheating, while the heat sink is used especially for the processor as it gets overheated quickly.
What are the use of three input devices?
Here are the uses of some of the common input devices:
Joystick: A joystick is used for moving game characters and controlling action on the screen.
Mouse: A mouse is used to move a cursor on the screen and make selections.
Scanner: A scanner converts documents into computer images.
Webcam: This is used to capture still images and video of the user and the room.
Can you add a pci express slot to an older computer?
No but you can find fairly nice video cards that fit into older expansion slots on ebay.
Is DVD need a hard drive to be read?
yes a DVD does there is hardly no way u can watch a movie from a DVD with out a Harddrive, a Harddrive is what Run's ur computer with out it, it surely wont work at all
How can you distinguish memory slots on the motherboard?
If you are referring specifically to what a memory slot looks like, they will be paired slots, normally located (if holding the motherboard upright) toward the top-right of the board. Newer boards will often have up to 6 memory (or RAM) slots, paired, with each pair being a different colour (for example pair of red, pair of grey, then a pair of red).
However, if you are wondering how to find out what RAM your motherboard supports, more often than not, if you still have the motherboard documents, the booklet from the motherboard packaging will contain that information. If you don't still have it, look on the motherboard for the make and model and put it into a search engine (or go to the manufacturer's website!)
Advantages and Disadvantages of Reproductive technologies?
Copying something generally weakens it, and scientists have found this true of cloning. All cloned animals have died early of diseases or genetic issues.
The cloning of human body tissue also brings up several ethical questions. Who will own the tissue? The carrier of the DNA, or the scientists who create it? Will the monetary costs of cloning be worth the final result?
Finally, there are those who worry that cloning allows man to "play God." Is it really a good idea for one human to be able to create another human?
There are several disadvantages associated with cloning, such as significant scientific uncertainty, medical risks, potential effects of aging, somatic mutation, and improper imprinting. A cloned child is not really a couple's genetic child, but the child of only one of them. That imbalance may produce strains on the marriage the child might suffer identity confusion, and there is a risk of perpetuating the cause of sterilityOffensive, repugnant, disgusting, grotesque, and repulsive are the kinds of terms used by many to describe the prospect of cloning a human being. These are universal feelings of many commonfolk, inte BenefitsOne benefit of cloning human tissue is that if researchers can grow vital organs, they can be used to replace ailing organs. For example, if heart disease destroys a patient's heart, an exact replica can simply be "grown" to replace it.Human cloning can also be a solution for infertile couples, even allowing the couples to create a child with certain features. Because cloning allows for the manipulation of genes, embryos can be created free of inherited genetic disorders or predispositions.
The cloning of human tissue could also be used to treat cancers, and even for plastic surgery.
There are five important reasons why animal cloning might be useful: (1) to generate groups of genetically identical animals for research purposes; (2) to rapidly propagate desirable animal stocks; (3) to improve the efficiency of generating and propagating transgenic livestock; (4) to produce targeted genetic alterations in domestic animals; (5) to pursue basic knowledge about cell differentiation.There are five potential uses for cloning humans or human cells: (1) a research tool to understand how genes in cells can be switched off and on; (2) growing new skin for burn victims; (3) culturing bone marrow that could be used to treat cancer patients; (4) manipulating genes to cure sickle cell anemia; (5) potential application in treating infertility.Human cloning can also be a solution for infertile couples, even allowing the couples to create a child with certain features.
The cloning of human tissue could also be used to treat cancers, and even for plastic surgery.
One benefit of cloning human tissue is that if we can grow vital organs, they can be used to replace ailing organs.
What is the difference between values and ethics on a database?
ethics are what you belive is the right thing to do love
What does 24x mean on the DVD R package?
Anytime you see a number with a x, like (24)(x) it refers to a speed of that particular item.
The 24x on the DVD means that it can write the files to it at the spped of 24 bits per (x).
If you look further it may say write speed 24(x) and other information.
Most DVD drives can handle writing to a DVD/RW at this speed without any adjustments.
How do you delete Nero photosnap pictures?
Go to where the picture is located. Click once on it. Click DEL on keyboard. Click ok. Empty Recycle Bin. Note: For Windows users only!
OSD (On Screen Display) lockout. To resolve the issue you can hold the power button of the monitor until you get another message something similar to "OSD unlocked"....if the problem continues. Switch of the monitor and remove the power cable and connect it again.
How do you run a PC or laptop off a 12V battery?
Laptops usually require 18V or more and about 7 amps (depending on the model).
You can either buy a 12V converter to go straight DC-DC from a place like newegg or ebay.
Or a sufficient wattage (usually above 130W) inverter and plug your regular power cord in to it, although I believe the first option is a cheaper/better solution.
Is laser printer an input or output?
output, since you're printing out paper.
it's actually just logic. if it goes from computer to out, it's output. if it goes from outside to computer, then input.
What controls almost all function on a computer?
Well there are many devices which share the logical responsibility of running a total computer but I believe the device you're thinking of or looking for would be the CPU. Or Central processing unit.
This is the "brain" of the CPU that performs instructions and mathematical calculations. When you launch a program, it's running on shared cycles of a CPU.
Hope that helps!
Are mainframe computers mass produced?
No. Don't get confused between a mainframe and a server.
- a mainframe takes up a whole story on a building, sometimes even the whole building.
- a server (which is mass produced) is basically a desktop computer with some simple modifications
Is a hard disk input or output device?
Hard disk drives are storage devices, they use an I/O buffer so to answer your question, they are both. I/O stands for input/output.
Speakers are a good example of an output device.
The mouse is a good example of an input device.
Provisions for enabling and disabling onboard drive controllers and other embedded devices?
You must enter the CMOS setup in order to enable or disable onboard drive controllers and other embedded devices.
What do you need to make a video clip from a DVD?
your need buy VHS TO-DVD VIDEO CONVERTER Gigaware is the best and to easy for user
Dell Dimension E510 proublems staying on?
If you mean it doesn't turns off try to unplugg it (if you scare it could be damage do the following).
Option 1: Try to mantain clicking the off button for a while...
Option 2: Try to reboot system.
Option 3: Try to turn it off with the system...(Start, Off)
Option 4: Try to use a Shut Down with a "let's say program" (Follow these steps)
First, Rigth click the desktop
Then, New-Shortcut
After that you type in the address box (The letters in bold) shutdown -s -t 20 -c "Auto Shutdown"
(In the Auto Shutdown you have to put the apostrophee)
then it shuts down in 20 seconds (beside the -t means time, put the amount of time you want, beside the -c its the message, write watever u like.)
How is input entered on an actual pocket PC device while an application is running?
Pocket PCs would use Stylus, Human-Finger, on-screen keyboard, wireless or wired connected keyboards as input devices.
Parallel buses can carry more information since data bytes don't have to be split up and sent down the bus single file. But their electrical characteristics make them good only for short physical runs, less then ten feet or so. Serial buses can be run over great distances, and their speed has been improving. That is why parallel buses are preferred for inside computers, and serial buses are used for connecting computers and peripherals. Firewire and USB are serial protocols.
One of the most popular parallel buses of all time is the IEEE-488 bus, also known as the HPIB or GPIB bus. The IEEE-1284 parallel port used to connect printers to computers is known as a Centronix port. It's hard to find any printers that still support that interface.
A parallel port signify that data is transmitted broadside as opposed to serial data whereby data is sent out singly as a water brigade one of the time. Parallel port can function up to hundreds of feet not few feet. It all depends on the speed of transmission. HAT CAN BE SAID OF BOTH TYPE.
A parallel port is a port straight from the main bus system in the computer. It used to be sent on flat ribbon cable. The idea was 16 bits of information could be sent simultaneously unlike serial that as its name suggests relies on information sent Dow a wire bit by bit. Years ago parallel was much faster over short distances than serial.
Problem with parallel and reason for the short cable length was that you had to guarentee all 16 (or 32) bits of information arrived at the same time. Imagine the chaos if the 16t bit arrived after the first 15. The instruction would be screwed.
What can a cordless trackball be used for?
A cordless trackball is a type of human interface device for the computer. Specifically, it is an input device used to control the mouse cursor on a computer screen buy way of spinning a ball on top of the device with your fingers.
