How many megabytes equal a terabyte?
Everything in the decimal system gets a new name for every power of 1,000
So .... * 1,000 bytes = 1 kilobyte * 1,000 kilobytes = 1 megabyte * 1,000 megabytes = 1 gigabyte * 1,000 gigabytes = 1 terabyte * 1,000 terabytes = 1 petabyte So 1 terabyte = 1,000 x 1,000 = 1,000,000 megabytes
How do you make a CD rom into a DVD rom?
The simple answer is you can't. A DVD-r is physically different from a CD. You can use it in many ways like a CD, but in the end, it is not a CD, and you will only be able to use it in a DVD drive or player, regardless of what you do to it. They are apples and oranges. Both edible, but not really comparable beyond that.
Should Cache memory be deleted?
Usually not. Contrary to popular belief, deleting a web browser's cache usually does not affect overall system performance, and will make it take longer to load a web page, since it will have to redownload the images.

Why does the motherboard sometimes support more than one bus speed?
<Original Answer> because some devices on the board are slower than others and do not require or cannot support the same bus speeds.
<Update> The book that this question comes from has another answer: that it is required for backwards compatibility. This is the answer for the test, but, I do not like it.
My answer is that having a high speed bus to some devices is a waste of CPU effort that could be better used on RAM or other high-speed items. There is not point to putting a modem or printer on a high speed bus that the CPU has to monitor only to find out that the printer or modem is done with the last burst of data sent.
Difference between DOS and Windows XP?

What is the difference between communication in Telephone system and in computer networks?
3) The telephone is ubiquitous. However, the reality is that 80% of the world's populations have limited access to one. To make a telephone call, one simply picks up the handset, enters a number, and waits for the system to perform its magic. The office acknowledges the request for service by sending dial tone. The telephone line goes to a terminal block in a service area interface. These are often located on a pole or small enclosure on the street. The service area interface bundles the subscriber drop cables into a single larger cable. These are in turn gathered together to form larger feeder cables. The entire wiring system somewhat resembles a huge tree. Cables coming out of a central office may have hundreds or even thousands of pairs bundled together however by the time the cable gets to the end user, it is generally down to about 50 pairs. An individual subscriber consists of many cable sections spliced together. Bellcore claims that the average U.S. subscriber line has twenty-two splices. Lifting the handset from its cradle releases a hook switch and causes a dc current to flow (20 - 120 ma). To the average person, the telephone system is simply a 'black box'. Relatively few people need to know how the PSTN works. The main consideration is that it works, and is relatively inexpensive.
Which Peripheral devices use serial communication?
Most modern peripherals. USB devices, Firewire devices , SATA hard drives, PCI express cards and Ethernet are all examples of devices using serial communication.
1 mB (megabyte) is either 1000 kB (kilobytes) or 1024 kB depending on the context. So 2.5 mB would be roughly 2500 kB or 2560 kB.
Nvidia graphics card are they good?
Nvidia make some of the best graphics cards around.
The Nvidia 550 ti is a very good card from their range.
What is One billion bytes of data is called?

Why have the usb ports have stopped working on a computer how can you fix this?
I experienced this problem this moning, the answer was not that difficult to track down.
I am running vista x64 and the answer came from HP Advisor. Upon starting the computer I plugged a memory stick into the card reader but the operating system did not find it. I went to my computer to see if I could find it as a drive that was now plugged in and I would load it from my computer. I noticed that there were no drives showing except the hard drive and DVD drives. All the USB and Media drives were absent. After several attempts at trying to find the Media card I had plugged in, I thought, try the HP advisor (the media reader was supplied by HP). After finding it in the FAQ It was a matter of starting Media Centre to check if in fact the media card had been read. The next step was to shutdown Windows and unplug the power cord. Wait a few seconds. Reconnect the power cord. Start the computer again while holding the start button for five seconds. Once the computer restarted and the windows screen came I went to My Computer and there were my USB and media reader drives.
How is true multi tasking achieved?
True multi-tasking is achieved through parallel processors. If you only have one processor, only one task can execute at a time. You can still multi-task by rapidly switching between all the running processes, but you cannot have two processes running simultaneously. With two or more processors running in parallel, you can.
What is disadvantage of using two 512 MB of ram instead of one 1 GB?
1) Redundancy: a failure in a single 256MB is critical where as a failure in either 128MB module leaves you at half capacity.
2) Speed : accessing two separate devices is usually quicker than accessing a single device.
However up sides to the single module is usually cost and free slots to expand further.
