A single-session disc (CD-ROM-Read-Only Memory) can read but not write (record) or erase. Manufacturers write all items on the single-session disc at one time, and multisession disc (CD-RW-Compact Disc-Rewritable) is an erasable disc you can write on multiple times.
A writing board is a smooth vertical surface upon which a person can write with an erasable material.
use a laser to read and write data. Optical disks have very large storage capacity but they are not fast as hard disks. There are three basic types of optical disks: CD-ROM, WORM and erasable. DVD-ROM is higher- capacity disc
One example of a sentence with the word "optical" in it would be: He looked at the optical illusion on the piece of paper.
Optical disks are defined as "Write Once/Read Many" media. Some optical disk can be re-written. This is accomplished by burning the first layer smooth and writing the bit bubbles again. This can only happen a few times before the optical media is spent. Magnetic disks are defined as "Write Many/Read Many" media. This is what is needed for the continued operation of a computer over any extended duration.
you have to invision it multiple times and write it down a lot of times
The erasable pen, known for its ability to remove ink with friction, was first introduced in 1979 by the Pilot Corporation under the name "Friction Pen." This innovation allowed users to write and then easily erase their mistakes by rubbing the special tip against the paper. The concept of erasable ink had been explored before, but the Pilot Friction Pen popularized its use in everyday writing.
You can't because math is a subject involving erasing LOTS of it, even if you use erasable pen its considered better to use a pencil..... :)
TAILORS; when tailors make your clothes,they use that chalk.(it might be erasable) PENCIL; you use it to write your assignments on the paper.
Blu Ray disc
Compact Disc ReWritable is a term used to refer to CDs that you can write data to multiple times.
