Is there a difference or this is same terminology used in different fields?
How can this be explained to layman?
drinking water has salt, ions and some mineral and organic compounds. When it is intented to purify water with distillation column only salts and particles are removed. the remaining water still has ions and others. To highly purify water, this stream should pass ion exchange materials to capture ions.
as simple as i colud
resistivity , pH, conductivity and .... differ in these types of water

Hi, distill water is free microbial water, deionized water is free of slate and minerals
Theoretically, distilled water is obtained from a distillation process and it is assumed to be absolutely pure water. But substances with similar boiling point to that of water can slip in the distilled water. There are no dissolved salts in the distilled water because the salt boils at a much higher temperature. To eliminate the problem of organic substances, the water distillers have pre- and post water filters.
On the other hand, deionized water is deeply demineralized and it is like an ultrapure water. It is used in microelectronics, instrument manufacture, pharmacy etc. High quality deionized water is usually obtained by using a multi-stage water purification process. After pre-cleaning, the water is supplied to the reverse osmosis membrane, and then the water is filtered through a special deionization medium which removes the ions present in the feed water. The purity of deionized water can exceed that of the distilled water.

Thanks!
Distilled water is highly purified water that does not contain any salts. It is produced by boiling water into steam and then condensing the steam. As a result, organic substances having boiling point less than that of water and oils present in water can be present in distilled water. Deionized water is ultrapurified water containing no ions other than H+ and OH-. It had resistivity nearly equal to 18 Megaohm-cm. After distillation, water is passed through a reverse osmosis membrane and a deionizing membrane which allows only H+ and OH- ions to pass through, to finally obtain deionized water.
@ Zeeshan Ahmad , why did you mention oil in your answer?

Deionized water is water that has been purified in such a way that (most of) its mineral- and salt ions are removed. You can think for example of Calcium, Chloride, Sulphate, Magnesium and Sodium. . Deionized water is generally considered different from distilled water. Distilled water is purified by boiling and re-condensing. In this way salt ions are being removed.
The major difference between deionized water and distilled water is that distilled water usually has less organic contaminants; deionisation does not remove uncharged molecules such as viruses or bacteria.Deionized water most times has less mineral ions; this is dependent on the way it is produced. Deionisation has a cleaner production and it leaves behind less scale in the installations it is used in.
