Define input devices .with some examples?
The input and output devices of a computer are normally abbreviated as I/O devices.There are a variety of input units,which are used by computers.THE MOST COMMONLY USED UNIT OF THIS TYPE IS A KEYBOARD AND A MOUSE OF A DESKTOP COMPUTER.Special purpose units are scanners,magnetic ink character reader,optical mark reader,optical character reader and bar code reader.
What is the Unit for Dispersion in optical fiber?
unit of dispersion is: (picosecond)/ nanometer kilometer
What are the 12 elements of inside the computer?
motherboard processor+ hsf northbridge southbridge gfx card sound card ram hard drive or ssd optical drive floppy drive flash card reader power supply unit
What is the SI unit of converging ability of a lens?
Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device.[1] The dioptre is the most common unit of measurement of optical power. The SI unit for optical power is the inverse metre (m−1).
When was Mark W. Michael Unit created?
Mark W. Michael Unit was created in 1987.
How do you calculate optical power?
Optical power is calculated by dividing the energy of the light beam by the time it takes to deliver that energy. The formula for optical power is: Power (P) = Energy (E) / Time (t). The unit of measurement for optical power is watts (W).
The tool that lead to the understanding that cells are the basic unit of life was the?
The optical microscope.
Optical power of a concave lens is?
The optical power of a concave lens is negative, as it causes light rays to diverge when passing through the lens. The unit of optical power is diopters (D), and it is the reciprocal of the focal length in meters.
What is a Navy REO?
"REO" is the acronym for "Radar Electro/Optical", the radar unit ofmilitary aircraft.
Optical density measurement unit what is D?
In optical density measurements, D typically stands for "Absorbance" and is commonly used as a unit of measurement to quantify the amount of light absorbed by a sample. The higher the D value, the more light is absorbed by the sample.
What are the standard units used to measure the optical density at 600 nm in a spectrophotometer?
The standard unit used to measure optical density at 600 nm in a spectrophotometer is absorbance (AU).
What are limitaion of optical disk?
Reusable. The write-once read-many (WORM) characteristic of some optical media makes it excellent for archiving, but it also prevents you from being able to use that media again.Writing time. The server uses software compression to write compressed data to your optical media. This process takes considerable processing unit resources and may increase the time needed to write and restore that data.
