The record can include display settings, application settings, and network connections. What the user sees on his or her computer screen, as well as what files, applications and directories they have access to, is determined by how the networkadministrator has set up the user's profile.
In organic chemistry, functional groups are specific groups (moieties) of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules.n addition, functional groups are used to covalently link functional molecules to the surface of chemical and biochemical devices such as microarrays and microelectromechanical systems.
Functional groups are specific groups of atoms or bonds within molecules. They are responsible for the characteristic chemical reactions of those molecules. Functional groups are attached to the carbon backbone of organic molecules. They determine the characteristics and chemical reactivity of molecules. The same functional group undergoes the same chemical reactions regardless of the size of the molecule it is a part of. Functional groups are less stable than the carbon backbone. They are more likely to take part in chemical reactions.
