Is there anything you can get to give your computer more GHz?
If by "get more GHz" you mean speed up your processor, it's a lot harder to do on a laptop. You could overclock it, but most laptops have very few options for overclocking and overheat easily due to the excess heat created. If you need a faster computer, I recommend buying a desktop (which you can actually overclock) or upgrading to a better laptop.
Here is a great overclocking guide:

AGP (Accelerated Graphics Port) is a computer bus designed for video cards. It is faster than PCI, but has been supplanted by PCI-E.
AGP, or Advanced Graphics Port allows the use of a high speed graphics card which can considerably improve performance of the computer video. The AGP slot only provides the possibility of improved graphics, next you need to get a high quality AGP CARD.
What is the maximum length of a usb hi speed cable?
Hi-Speed USB cables can be up to 5 meters (16 feet, 5 inches).
Some people sell USB extension cables, but these are outside the USB specification. The electrical characteristics of the cable are important. Chaining them adds too much delay, resistance and capacitance. You might get lucky, or you might not.
Why is it harmful to turn off power to your computer without first shutting it down?
Almost all computers have tasks that are either ongoing or need to be done before it is shut down, thus, cutting the power to it could have negative effects on it, as compared to allowing it to communicate to these tasks that it needs them to either run or stop, and letting them do what they need to do.
The hardware and software used to transfer data in an organization is called what?
Networking and telecommunications technology
How does a price scanner work?
A price scanner is often found in supermarkets and they allow customers to check the price of any given product. A price scanner works by reading the bar code.
How are the three components of the computer related to each other?
Assuming those 4 elements are the processor, memory, hard drive and motherboard. The hard drive stores all your files no matter if the computer is on or not. The memory is were the files from your hard drive go so the files can be easily managed since memory is much faster then the hard drive (mechanical vs. electrical). The processor handles all of the operations of the computer and the motherboard is the highway system that transfers the information to the various components.
The four elements of the computer are:
1 hardware
2 software
3 operating system

What are the health and safety risks when installing hardware?
Firstly, make sure you have cut off power to the machine (unplugged it, removed any batteries etc). Also, make sure you are grounded at all times. To do this, you can use a grounding strip. Make sure that the hardware components and cables aren't visibly damaged before you plug the machine back in.
Generally, powering up isn't as much of a problem, although certain peripheral equipment may not be identified during startup if they aren't already on when the computer tries to find them. Just put everything on a single shut-off switch and that problem should be solved. As for the shutdown process, certain operating systems leave files in strange "states" during operation and if the computer does not go through an orderly shut down the files will not be updated properly and will be corrupted next time your computer attempts to read them.
For removable media the above answer is true. If the hardware is a peripheral accessory device (scanner, printer, etc) the only risk is corrupting the operating system (typically & unfortunately Windows) drivers which could (but unlikely) have adverse and unpredictable results. The damage or dysfunction which could occur to the actual hardware are always described in the documentation which came with the device.
Is a 2.2ghz computer a powerful computer?
there are many types of processors. if you have double 2.1 it's quite good for usual work and normal gaming. middle Vista computer is Duo 2.0 GHz
What does defragging the registry do?
- Defragging fixes the spaces left behind on your hard drive and makes it run smoother. For example, every time you save something to your hard drive it is put at a certain address so your computer can find it later. If you then delete that data, it leaves an empty space on the hard drive where the data used to be. What defragging does is to close all the spaces and move all the data together, so that your computer can find it better. You should defrag about once a month.
- No, that's defragging the whole hard disk and even then that's not what basic defragging does. Defragging the REGISTRY does not involve the entire hard drive, but just the system registry. It essentially consolidates it when keys are deleted or altered. As far as a noticeable difference, you will not see one.
Defragging the HARD DISK on the other hand involves consolidating fragments. When data is saved to a hard disk, it will saved scattered sometimes. The data from one file could be in fragments all over the hard disk. Imagine reading a book where the paragraphs that would be on one page are scattered at random intervals. This would take a lot longer to read with all the jumping around. When you defrag the HARD DRIVE, those fragments are brought together to decrease read time. Hence the term, "defragment". So basically, you can have all the spaces you want between the data and still have a minuscule percentage of fragmentation. Fragmentation is caused from writing, not deleting.
What the original contributor described above is file consolidation or a "space" defrag which is not standard and is usually found as a supplemental option with third-party defrag applications such as O & O. It too can have benefits, but it is not what defragging means and certainly not the REGISTRY as you were inquiring about.
What does Graphic cards and sound cards do?
Sound Card
A sound card is an expansion card which is used to send and recieve the sound signals and installed in a PCI slot of the motherboard.
Graphics Card
Graphics cards are the video cards which are used to produce the images you see on a monitor screen and it is installed on the motherboard as an extra component and used to graphical data with a high quality colour display and clear appearance.
What sort of input does a keyboard support?
A keyboard is an input-output unit that is supported by the operating system. The functions supported depend on the design and usefulness of the keyboard.
Typically, a keyboard supports alpha-numeric keystrokes. In addition, some keyboards also include a numeric keypad with special keys indicating addition and subtraction.
Most keyboards also contain up to 12 function keys, each with a special purpose, depending on the operating system and other software application that is in use by the keyboard operator.
Some keyboards also include a mouse-like feature, sometimes called a 'pencil eraser'.
Depending on software, keystroke combinations can also invoke special actions.
Output to a keyboard may be limited to feedback sounds or lights.
Which operating system is responsible for interacting with hardware?
All operating systems interact with hardware.
What is the function of a GUI icon?
They act as symbols to allow the visitor an easier and smoother browsing experience.
What is the difference between a gigabyte and MHz?
gigahertz is the processing speed of your CPU(eg. 1.8GHz,2.8Ghz etc).It's the speed at which your processor runs. Gigabytes is the unit in which data(any data)in your RAM,HardDisk,Memory card or any other storage device can be stored is measured.simply,Its the unit to measure the data storage capacity.Eg- 2GB RAM,160GB hard disk etc..
What is the full form of MICR code?

You can find MICR or IFSC codes of all branches across Indian at www.indiancodes.org
Its quite faster too.
How do I convert kilobyte to megabyte?
One MB (MegaByte) is 1024 KB (KiloByte).
Hence, to go from KB to MB you divide the number of kilobytes by 1024 and you're left with megabytes.
Most computers have several ports, which may or may not be enabled. There are two serial, or 'com' ports, which transfer data to and from the Central Processor Unit a single bit at a time, and one parallel, or printer port, which transfers data eight bits at a time. Most modern computers have at least two Universal Serial Bus ports, which are a high speed port for operating modern peripheral devices, such as scanners, printers, external drives, and such.
How much does it cost to charge a laptop batterey?
