Schematic Diagram is a drawing showing all significant components, parts, or tasks (and their interconnections) of a circuit, device, flow, process, or project by means of standard symbols.
However, block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams.
And the pictorial diagram is a picture or sketch of the components of a specific system and the wiring between these components. This simplified diagram identifies components, even if you are not familiar with their appearance. This type of diagram does not show physical locations of components or the manner in which the wiring is marked or routed. It does, however,show you the sequence in which the components are connected
