It is divided into two types.
Hard real-time systems are needed to complete a critical task within a guaranteed amount of time. The scheduler then either admits the process, guaranteeing that the process will complete on time, or rejects the request as impossible.
This is called as resource reservation. Thus, hard real-time systems are composed of special-purpose software running on hardware devoted to their critical process.
Software real-time computing is less restrictive. It needs that critical processes receive priority over less fortune ones.
