If you have a type, it’s the kind of thing you are most attracted to. It might be redheads, men who remind you of your favorite movie star, sarcastic weirdos or tall people. It’s also the way you are — you might be a “type A” personality who likes to tackle projects quickly and efficiently or a “type B” who prefers taking it one step at a time.
You might have a “type” of car, too: a Ford or a Volkswagen, for example. Or you might have a “type” of person, such as someone with an easygoing attitude or a shy nature. It’s not clear how common it is to have a type, but research suggests that it’s pretty common.
In computer science, a type is a general description of the characteristics and properties of an object or class. For example, a chair has functionality (you can sit on it) and properties (four legs, red color). The type of the chair is defined by its TypeKind. When you declare that an object has a particular type, the computer knows what it can and cannot do with it at compile time, making it cheaper/better/faster to program.
The word type is derived from the Latin typus, meaning stamp or seal. Its synonyms include character, description, kind, nature and sort. Historically, the term was used in printing to describe a group of characters based on distinctive similarity and to prefigure something future. Other uses include typing, which means producing text via a keyboard or typewriter, and medicineto ascertain the type of a blood or tissue sample. type
