CD and DVD Drives

as much as it says on it

ANOTHER OPINION : Compact Disc (CD) can hold 740 MB. Digital Video Disc (DVD) can hold 4.7 GB. Usually says on the disc itself.

A driver CD is a CD that contains the software "program" that operates (drives) computer hardware. Many hardware components operate best when they are "driven" by the software created by their makers, rather than the generic drivers that are installed by the opperting system, e.g. Windows. In that case, the manufacturer will usually include those drivers, called device drivers, on a CD (they used to come on floppies) that the user can install on his/her computer by running the CD and following the instructions on the installation guide. Printers, for example, usually come with one, and computer makers include a driver CD containing device drivers for their components so the owner can reinstall them if necessary.

Different device drivers must be written for each operating system and they are usually included on manufacturers' Driver CDs for Microsoft and Apple operating systems. Finding and installing them on UNIX and Linux systems can be difficult for a new user since manufactures frequently don't include them on their driver CDs, but this situation is improving.

There are 2 main types of CDs: CD-Rs and CD-RWs.
* If the CD is a CD-RW (or CD+RW) then yes, you can wipe it and start again. To do this use any CD burning program: something like Nero would do fine. * CD-Rs are not erasable. However, if you originally created the disc with something like Nero, you may have been offered the option of "Starting a Multi-session disc" or something like that. If you chose that option, then you would be able to burn more files onto the CD until it is full, however you still would not be able to change or delete existing files.

The answer to how does a future CD or CD player look like?? Well I'll tell you that!! Okay so the Cd player lights up and you can tell it what movie you want on even the ones that arn't even out yet!! and a CD looks just the same exept it's thicker and of corse lights up for more info about anything else call 519 941 4823

A CD-Recordable disc, often called CD-R, is a CD that can be recorded onto, often referred to as burning a disc, once whereas a CD-Rewritable disc, often called CD-RW, can be recorded onto many times by erasing previous material from the disc. Some CD players have problems playing CD-RWs while CD-Rs are less problematical.

Storage capacity on cds varies slightly among media manufacturers. A Compact Disk (CD) can usually store up to 700MB data. Disc capacity is expressed in terms of how much Red Book digital audio (in minutes) and computer data (in megabytes) a disc can contain. The market standards are, 74 minute/650 MB, 80 minute/700 MB (12 cm) and 21 minute/185 MB (8 cm) discs.

This is due to the classic difference between GB and GiB, KB and KiB. Humans think 1KB = 1000 bytes while computers think 1 KB =1024 bytes (2 to the 10th power). To be more accurate (and avoid this confusion) 1024 bytes should be referred to as 1 KiB (kibibyte). A DVD can hold approximately 4.7 GigaBytes (GB) but only 4.37 GibiBytes.

A DVD (digital video disk) is used for video and audio media.

yo don't

It is using the EIDE connection. The book says that if you have a hard drive and a CD that the hard drive should be the master and the CD will be the slave.

Yes, a CD - ROM is a non volatile storage.
A non volatile storage media retains its stored data even if the power goes off.

Numerous products and ideas are invented every single year. In 2005, the internet video site, YouTube, was invented. Additionally, Google introduced Google Maps in 2005.

ROM=Read Only Memory

True ROM is screened at the factory as is a Microprocessor. It cannot be changed without destroying the contents. There are many advantages to this as the contents can be counted on to remain the same throughout the life of the device it is installed in. This is also the major pitfall as it is not upgrade-able either.

ROM is a perfect medium to store boot-time instructions for a computer or portable device which are expected to be unchanging. Reading the boot track data for a device that includes magnetic media is one use for ROM. It can hold simple hardware diagnostics. It can also include audio-visual information such as standard sounds and icons or simple startup sounds and textual cues for system errors.

Almost all electronic media that is distributed on some hardware uses ROM. Video games, DVDs, music. Almost anything that you would READ but not CHANGE.

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.

Some new programs may be able to pass through the read only protection, if your program does not you will have to copy to hard drive first, then disable the "read-only" attribute of files by right-clicking files, and selecting "properties". In properties un-check the box "read only" and save.

To copy files to hard drive you will have to use "Command Prompt" accessible from the start menu, or you can go start>run>cmd.exe

Once in command prompt the command to copy read only files is xcopy:

xcopy (directory to copy from ex. e:\) destination (enter destination parameters here) and hit enter

for more information you can also use the command: xcopy /?

if still in trouble try to google xcopy

1. Importance of medium.

By the 1980s, hard disks had a seek time of ~20ms and today that's just down to ~10ms (on a consumer disk). So for the simplicity of argument, the HD seek time has "just" improved double. Numbers for historical CD-ROM seek times have eluded me, but it hints towards being ~90ms in 2000.

So one idea is simply: CDs were initially just meant for sequential reading of CD-DA. And, later on, do not seem to be considered as important as hard drives, or we would have seen improvements in stepping technology here.

2. Type of interface

Note too however that CDs act using optical means, while a spinning hard disk fares with magnetic - it might have to do something with processing delays, specifically the D2O/O2D converter in the optical components.

3. Caching

Copying a file in DOS always seemed a long business in the 90s on my personal box. There were indeed many seeks involved (and you could hear that). However, I have seen SMARTDRV in use on similar powerful models, and it seemed to make the procedure more responsive (at the cost of memory).

Now, hard disks have gotten more caches over the decades, currently they have something like 2 MB, or even more, while CD ROM drives seem to be still stuck at 128 KB.

CD stands for compact disc.

Random access memory (RAM) is memory that can be written to easily (which usually means by the device where the memory's installed). "Random access" means any part of the memory can be got at immediately.

RAM needs to be supplied with power to keep what's in it. ROM (Read Only Memory) doesn't, but writing to it is more difficult - you usually need a separate writer.

Random access memory is more commonly said as RAM. Random access memory or RAM is what some of the speed of your pc or laptop comes from. RAM Looks like a long chip that goes inside your computer and it comes in gigabytes and most computer have 2 RAM slots so E.G. my laptop has got 4gbs of RAM. it has to 2gb sticks. there are about 10different RAM stick ones with 200 pins, 204pins, 240pin etc.

If your computer is having trouble opening your CD try this. With the disk in the drive, go to My Computer. Right-click on the drive and choose Explore. To fix the Autoplay feature you may want to go to http://www.microsoft.com/downloads/details...;displaylang=en

No. There is a huge difference between the lasers (a 130 nanometer difference, to be precise). In short, the two formats use different lasers, and the CD player cannot handle DVD.
