Etching is done with acid, its used to eat away material that is exposed to it and material that is covered is untouched
Engraving is actually carving something with tools
You could have found this out yourself using something thats available these days, called a SEARCH ENGINE
The primary difference between etching and engraving in intaglio printing lies in the techniques used to create the designs. In engraving, an artist uses a sharp tool called a burin to directly carve lines into a metal plate, resulting in crisp, precise lines. In contrast, etching involves coating a metal plate with a waxy ground and then using an acid to bite into the exposed areas after the artist scratches through the ground, allowing for more fluid and varied line quality. This leads to distinct textural differences between the two methods in the final prints.
Cameo Surface: The surface that you can see. Intaglio Surface: The surface that you cannot see. Example, there is a dish on the table. Upper side of the dish is cameo surface and the bottom side of the dish is intaglio surface.
The embossing effect found on an intaglio print is often referred to as "debossing." This occurs when the inked image is pressed into the paper, creating a raised texture on the surface. This tactile quality is a distinctive feature of intaglio printing techniques, such as etching, engraving, and drypoint. The result is a unique interplay between the printed image and the paper's surface.

intaglio is when a design is carved into a surface such that it appears as a depression. cameo is when the required design appears as relief left remaining on the surface as the unrequired material is chipped away. it appears raised or as an embossing on the surface.

Carved in relief means the thing that is carved was beautiful and it looks real that you can't belie it. Engraving in relief means A deeply cut background with flat bottom and clean, sharp sidewalls.
The BEP makes paper money and the US Mint makes coins......I think.
Intaglio: image is etched into the surface, smeared with ink (which sticks in the recessed areas), and (using damp paper) put through a press. The ink is transferred from the recessed areas to the paper. Relief: Pretty much the opposite; the parts you don't want are carved away, ink rolled on, and dry paper pressed onto it. In layman's terms, it's a big stamp.
The difference is that competing processes in an operating system compete for resources. Cooperating processes share resources, and some even work together to complete the same task.
