Name the two types of microscopes?
There are a variety of microscope types, but two large and different types are electron microscopes and optical microscopes. Optical microscopes are cheaper, and are commercially available for even you to buy. They work with lenses, and in many cases, oil emulsions. Electron microscopes work by bombarding specimens with electron beams. They are significantly more expensive than optical microscopes, but give a better quality image and come with vastly superior magnification levels, due to the fact that electrons have wavelengths circa 100,000 shorter than photons, or light. This enables you to see things in much greater detail.
What are the optical system of a compound microscope?
the optical system of a microscope is the objectives
What instrument uses light and lenses is used to view cells?
An optical microscope uses light and one or more lenses to view cells. An optical microscope with two or more lenses is called a compound optical microscope.
What optical aids was nearsighted model?
Glasses
What type of device is a CD-ROM Drive?
A CD-ROM ( Compact Disc- Read Only Memory ) is an Optical Type of Device. The reason of it being optical lies in the fact that its read/write head is optical in nature ( It uses a red colored light).
What are the types of storage devices that are read by lasers?
CD (Compact Disks) DVD (Digital Versatile Disks) Blu-Ray optical disk
What are the advantage and limitation of optical disk optical disk?
Optical use a laser to read and write data .Optical disks have very large storage capacity but they are not fast as harddisk .There are major types of optical disk 1.CD-Rom 2 Worm 3.Eraser Advantage's optical disks has a very high storing capacity ,inexpensive has along life of at least 25 years .
What is an optical disks?
an optical disk which stores data optically
Give two reasons why optical disks are commonly used as a medium for the distribution of software?

What is the meaning of Optical Disk Drives?
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
What is meant by the word areal?
Word areal is also called bit density. Word areal is the amount of data that can be packed onto a storage medium. Those densities are measured in gigabits per square inch. The term is useful for comparing different types of media, such as magnetic disks and optical disks. Current magnetic and optical disks have areal densities of several gigabits per square inch.
What is Storage media used by optical disc drives?
CD and DVD disks are used by optical disc drives.
Are magnetic disk and optical disk secondary storage devices?
Yes both are secondary storage devices. Primary storage devices include RAM & ROM. Secondary storage devices include magnetic disks like hard disks and cds(optical disks)
What are the main categories of optical laser disks?
Main categories of optical laser disks are CD-ROM,WORM Disk/CD-Record able(CD-R) Disks,CD Read/Write(CD-RW) Disk,Digital Video(or Versatile)Disk(DVD).
What is the function of a disc drive?
A machine that reads data from and writes data onto a disk. A disk drive rotates the disk very fast and has one or more heads that read and write data.There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks.Disk drives can be either internal (housed within the computer) or external(housed in a separate boxthat connects to the computer).
