USB 3.0 (sometimes known as USB SS) is significantly faster than USB 2.0 as it has 8 pins instead of four, allowing for theoretically double data bandwidth.

It is backwards compatible with USB 2.0 and USB 1.0 also.

An unpatched copy of Mac OS X will not install on a standard PC. There do exist cracked versions of Mac OS X that will allow you to install it on a select variety of PCs. WikiAnswers does not provide any information on how to patch OS X, nor any information on how to install it on a non-Apple branded computer.

I don't think so. A DVD burner is necessary to burn a DVD. DVD or CD-rw drive could not burn DVD. And if you use a CD burner to burn DVD, when you play it, you will discover that only the audio is available, you can't get the picture.

Permanent storage device such as a hard drive.

There are some basic files which are needed to load in the RAM for booting the system.

Coming to your question, All the boot files are loaded in the RAM while starting up the systems, and this information is temporary in nature. this information destroys everytime system shutdown.

It depends on the specific model. Dell contracts several different manufacturers for their laptops and each has different habits of removable or not.

- AFAIK most of the XPS series have graphics cards soldered to the motherboard, but there are a few different motherboard revisions, so you can upgrade the motherboard E. G. m1530 has geforce 8400m or 8600m versions. m1730 has removable card and can be upgraded to 9800m GT or GTX SLI but only a Dell m1730 card. M1710 is actually the same as a Dell m90 or something and uses a few removable cards.

the studio XPS 1640 has motherboards with ATI 3670, 4670 and 5730.

-Dell Alienware m15x, m17x and m18x use MXM 3.0 B graphics just like most Clevo/Sager and MSI gaming systems. You can find and change out high end cards like AMD 6990m and Nvidia 580m in all of these.

- Dell Precision m6500 and m6600 also use MXM 3.0 B cards, come with professional Quadro and Firepro cards but can be changed for others. The m4600 uses smaller type MXM 3.0 A.

Anything released earlier than these laptops cannot use different graphics cards or can only use cards made for the specific model.

"Data" could be another term for input depends on the context. "data input device", "input device" - a device that can be used to insert data into a computer or other computational device

Im not sure exactly what input refers too in your question are you refering to any type of input? or a specific input? The input jack or the device?

There are many "computer paripherals" (basically anything that is pluged into your cpu) from hard drives to printers. Input could be used to refer to the actual data being inserted or the device your using to insert it . You will need to be more specific if i havent answered your question.

Personal computers come with an individual keyboard and screen.

Other types of computers (blades/mainframes/servers) don't and rely on a management console. You might have hundreds of servers or blades, and only one management console.

Secondary Storage in a computer is memory device other than primary memory like disk ,floopy, usb ports etc. they are used to store data for future use.

The difference is in the way how they process communications between two or more computers. If you send some information to one computer only using hub it will resend the information to all computers in the network. When switches resend information to the only one computer.

In order to protect your computer from malware, it is a good idea to have an anti-virus program set up. Try Avast or AVG, as these are both successful and free. You also will need to have a firewall.

A circuit board It is a board containing devices passive and/or active that can be installed on a system to make it whole. Usualy refered a PCB OR PRINTED CIRCUIT BOARD.
its a board of circuits

Some BIOS support a method ofdata transfer that allow multiple data transfers each time software requests data. This method is called block mode and should be used if your hard drive and BIOS support it. However, if you are having problems with hard drive drive errors, you can try disabling block mode in CMOS setup.

When updating your motherboards bios, you need to firstly find and download your motherboards bios update. Check the manufactures site of your motherboard.

Once you find your bios update, its important that it is for your own model motherboard, then they usually include a text document with the instructions on how to install.

It is usually done by a Floppy Disc and is known as "Flashing".

So first find out what make and model your motherboard is, then search for the latest bios update for that particular board, download it, read the instructions that come with the download. Or search "How to update your bios". Instructions are often given with download though.

A serial port is an interface in which one bit of data is transmitted at a time.

You will find the diagram on the website called "How stuff works"

Some input devices include:

Most computers still come with a phone jack expansion in one of the PCI slots, try plugging it into that, and ethernet cable into the onboard ethernet adapter. I dont use fax machines personally, so this is just a theory, but it should work. You will probably want to pick up an A/B splitter box with a manual switch at Radio Shack for like $10. Make sure the configuration is setup so the computer still has internet while you are faxing.

No. You have to be in range of a WiFi router (mostly this is limited to 100 meters or so for any one router).

However there are space based router satellites that one can connect to from almost anywhere (where you can see the sky) if you have the correct equipment. This is what journalists use when they are in the field.

Any normal computer works for a teacher!

it has nothing to do with the computer type or brand.There is nothing that special in a computer for teachers.

No RAM is not.

Open source products such as memtest86 found here http://www.memtest86.com actually overwrite RAM and then checks it for inconsistencies to see if memory is bad.
