CD and DVD Drives

CD-ROM is compact-disc read only memory.

it generally holds aboout 650mb of data or 74 minutes of audio.

it's generally less expensive than DVD and blue-ray, although generally DVD and blue ray devices can read CD-ROM data as well.

CD-ROM is a format (AUDIO CD, DATA CD), storage media (CD-ROM Disc), and type of device (CD-ROM Drive).

A VCD is a video CD-ROM. Same format as audio CDs except instead of encoding audio the disk holds encoded video and audio. The format is pretty much extinct now, but most PCs and DVD players will still play them if they are inserted.

Previous Answer: two types of magnetic disc are magnetic tapes and compact disc

Actually neither of the above are correct. Magnetic "Tape" is exactly that it is a tape, a long slender ribbon which comes in two formats that I know of which are "cartridge" and "reel to reel". Compact Disk is an optical media.

There are several types or formats of Magnetic Disk, sizes and capacities vary.

Fixed Disk:

Hard Disk otherwise referred to as HDD. It can have one or more disc platters made of aluminum alloy or glass with a thin magnetic layer bond. These magnetic disks or platters are sealed within the enclosure. Size 1.8", 2.5", 3.5", 5.25", 8", 12"

Removable Media:

Floppy Disk, removable disks that can be in a hard or soft shell enclosure. The disk itself is a plastic with a magnetic layer bond and is "floppy" one or both sides can be used depending on the disk. sizes range from 3.5", 5.25" to 8"

Floptical, the likes of a floppy however one side is magnetic for storage, the other is optical for head positioning. Size, 3.5"

Cartridge Disk, similar to the floppy or floptical but the cartridge actually contains a platter the likes of that within an HDD. Size 5.25", 8" that I know of.

it was invented in 2004 by sony and philips
The original optical disc was created in 1974, while the compact disc was created in 1977 and was made commercially available in 1982. Sony and Philips established the CD-ROM standard in 1985.

The CD that goes into a CD player is compact disc. CD-ROM is "compact disc - read-only memory".

On the back of a car, it means Corps Diplomatique, a French way of saying "I'm a diplomat so don't even think of arresting me".

In finance, and specifically investment, it stands for "certificate of deposit".

"Depending on which Bose CD player you are wanting; it determines how much you are going to spend. A portable one tends to run about one hundred dollars, while a non-portable one is about four hundred to five hundred."

They are used for watching movies and videos. Esp. since the video tapes are almost obsolete now.

It is possible to purchase external hard drives at most stores that carry computer electronics. These can be purchased at Best Buy, Future Shop and Tiger Direct to name a few. They are also available on both Amazon and Ebay.

a ROM is a copy of a game a computer can play one with an emulator and the native device can play it with software or hardware hacks they are illegal unless you have the game or they where given away free from the making company or person

No. 2.11 GB is much too large. You would need at least three (3) 700 MB CDs to hold that much data.

clean data

The surface is made of special alloys that are melted by the write laser in the CD-RW drive. These melted areas are read by the laser. When it's time to record over the CD, the laser heats up the alloy and melts the data into a new pattern.

Yes it will and that is the case for any CD being used anywhere in the world.

Unlike video, audio files are standardized globally so there are no different formats to worry about.

Unlike DVDs and other discs, CDs do not have any region coding so a CD player does not care where the CD came from.

It needs an image, title, age rating, price, bar code and something persuasive like "must see movie of the year".

no, you can only write to a dvdr once. A dvdrw can be rewritten on

External drive bays

You need a CD-ROM because then you can acess its read only memory

It is much cheaper to buy parts and build it yourself. Plus you choose the parts that you want, not the manufacturer.

You can't. CD-R is a read-only medium.

Some software will allow you to create a multi-session disk. This is generally only used for data discs though, not for music. With a multi-session disk you can burn multiple times, but you cannot write over any existing data. So, you still only get a total 700MB of data, but you don't have to write it all at once.

A PDA called Newton was invented in 1993.

When power is first applied like this, the computer starts by passing power to the motherboard and, consequently, the BIOS (Basic Input/Output System - the thing that controls how devices communicate with each other). As power is passed to all of the other system hardware, the BIOS does a check on each of these parts to make sure it's physically able to send and receive communication to and from the other parts properly, among a few other basic sanity tests.

Once the BIOS has confirmed that everything is operating correctly, and there won't be any conflicts or faulty signals, it proceeds to check its boot method. In the BIOS settings, your computer is usually configured to first check if there's a bootable disk in the CD/DVD drive, such as a Windows installation disk, and try to boot the operating system on that. If there is not one, then the BIOS will usually next fall back to booting from the hard drive. The hard drive, among a lot of other components such as your CPU and RAM, fire up, and start loading data needed for your computer to boot the operating system (for most people, that's Windows.)

Once the operating system loads properly, that OS' kernel (the part that actually allows programs to communicate with the hardware, and consequently, the user, through the BIOS) loads hardware drivers - pieces of software that not only tell the computer that hardware is present and functional, but actually how to use it - what to do when the user presses a key on their keyboard, what to do when the mouse sends an electrical signal detailing movement to the left, etc. Once all of the hardware is accounted for and assigned drivers, and the kernel is fully loaded, the software atop the kernel loads. The interface that you can point-and-click in, the code that runs in the background whenever you plug in your media player, etc. Then you may log in and operate your computer.

Amazingly, for most people, this entire process takes less than two minutes - and there are many, many more steps involved that have not been detailed here. If you (carefully) alter the right settings, both in the BIOS and the OS, as well as hardware tweaks, you can shave this down even further. Some people are able to get a computer to a fully operational state in less than 10 seconds.

An arithmometer is essentially a old school calculator. It's mechanical, rather than computerized, like today's calculators.
