Sheetrock-
Drywall is the term used for a common method of constructing interior walls and ceilings using panels made of gypsum plaster pressed between two thick sheets of paper, then kiln dried. Many such panels are made with fiberglass instead of paper to prevent mold growth, which is common with paper that has been exposed to water due to plumbing leaks or floods. Drywall construction is used globally for the finish construction of interior walls and ceilings. Drywall construction became prevalent as a speedier alternative to using plaster based interior finish techniques, which involved forcefully spreading a substrate of coarse plaster, known as the base (made up of the scratch coat and (optional) brown coat), onto the wall's lath-work before finally applying the smoother finish coat, each layer added in succession and all by hand.
Drywall, by contrast to plaster, requires hand finishing only at the fasteners and joints. The drywall process requires less labor and drying time, lending its name to the panels used in the assembly.

Blue Board Plaster-
There are fundamental differences in the application and therefore construction of drywall and blue board. Blue board receives a full skim coat of plaster. Drywall gets a low moisture tape coat of joint compound at the seams only. Because of this, drywall does not need to be a structurally sound or as capable of withstanding contact with moisture. It is less expensive because its composition does not need to be consistent, while blue board is one material (gypsum/plaster) throughout...
Blue board's consistent makeup allows it to breathe and dry. This is another advantage of blue board. If drywall gets wet, it is more prone to mold and mildew issues, whereas blue board will breathe dry over time and is much more resistant.
Lastly, with drywall and joint compound, you need to sand in between coats and that produces massive amounts of dust -- never a good thing in a healthy house.

Brown Coat Plaster-
Plaster is made of lime or gypsum, sand, and water and is one of the oldest building materials still in use today. Plaster that was applied to the Egyptian pyramids four thousand years ago is still hard and holds its integrity. Today it is applied in three layers: a base coat, a thick coat of plaster for strength, and a finishing coat.
Plaster can be applied to many surfaces, including wood lath, metal mesh, wallboard, or masonry. Plaster can be applied so that there are patterns such as swirls and peaks.
Plaster can be painted or pigment can be mixed into plaster before it is applied. Wallpaper and tile can also be easily applied over plaster.
