Difference between 40x and 52x CD-r?
The short answer is that 48X and 52X, in terms of media, are really the same thing. The maximum speed of Recordable CDs, according to the Orange Book specifications, is 48X.
The recorder manufacturers are the ones that started marketing their recorders at 52X, this pushed media manufacturers to then market their media as 52X certified.
The reality is you cannot achieve 52X record speeds. The maximum burn speed that we've seen is 47.2X with a full CD. The write speed starts off around 16X to 20X and climbs to about 47X for a full 700Mb CD, and then drops a little during the finalization of the disc.
That's why review sites, like CDFreaks, talk about how long it takes to burn a full disc at 40X or 48X speeds. The combination of the media quality and burn speed influence the overall time to complete the burn. It would be great to have a burner recorder at 48X speed for any size CD because then we could easily figure out the time it will take. Unfortunately, that is not the case, the amount of information on the disc coupled with recorder and media brand contribute to the overall burn time.
And, now, most folks are purchasing combo DVD/CD recorders and these recorders are only certified to burn CDs at 48X or slower. The dedicated CD-R only recorders are going away - everybody is now using these combo DVD/CD recorders so this whole 52X vs. 48X is becoming less important.
How many pins does the enhanced ATX power connector to the motherboard have?
A regular ATX motherboard uses a single 20-pin P1 connector with optional 4-pin auxillary power connector

Where can I buy a firewire cable?
For reliable quality you're going to want to avoid auction sites and instead order from a store's website directly. Any of your local electronic dealers will likely have a website, or you could simply stop in and ask. If you do a lot of online shopping I'd suggest you download an extension like Fastest Browser for Google Chrome, it allows you to hover over an image and it will show you any better deals with links in a handy little pop-up window.
What is the most common way to connect a computer to a monitor?
For years the most common connector has been a VGA or DB-15 analog connector. Most laptops still use the analog connection. However, today the Digital Visual Interface (DVI) is becoming the standard. There are several styles of DVI connector.
See links below for more complete explanations of these connectors.
What are the uses of different types of computers?

Server -------------------------------- Commercial use and data storage
Super computers -------------------- Military and weather forcasting
What the main difference between ATX and flexATX?
The main difference between ATX and BTX, is that BTX rearranges components on the ATX board to improve thermodynamics. Components changed that reduced the heat production within a PC, negating the need for the switch to the BTX board.
Where does a computer keep data instructions and information?
it depends on what your"information" means.
if it means files you have created, they will be stored on a hard drive(either default or selected by users).
if it means temporary internet web pages you have opened, they will be stored in RAM(Random Accessed Memory).
What are the six categories of hardware?
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.

Far more information is required to answer this question I'm afraid.
What exactly do you want to know??
SCSI (Small Computer System Interface) is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect other devices, including scanners and CD drives. An SCSI drive is usually referred to a disk drive that uses the SCSI standard interface and commands to connect and transfer data to/from the computer.
What is a universal serial bus port used for?
Universal Serial Bus allows to connect USB devices and uses hot-swap capabilities to simplify its
use. And is also used for charging devices such as a mobile phone, MP3 player, ipod, walkman, etc and is also used for running novelty devices such as a USB fan, USB light, all the way to USB microwaves
The expansion cards will not function properly without the right amount of power and the motherboard can only give so much power though the PCIe slots. Some expansion cards such as graphics cards require a lot of power so it is easier to get that power directly from the PSU.
What are cores on micro processors?
The "core" in a processor is the microprocessor inside of the CPU(Central Processing Unit).
For example, if you have a Dual Core CPU then you have 2 microprocessors inside of the CPU, this allows you to do two things at once, as a microprocessor can only do one thing at a time the only exception to this is Multi-Threading which allows one core to do the work of multiple cores, but its not as fast as having multiple cores.
