Nerf Blaster Assembly

Hello! I recently had to disassemble and reassemble a nerf blaster (still don't understand what half the pieces do) in my "how things work" class and my follow up assignment is to 1) provide a high level functional description as well as 2) describe the component systems of the disassembled blaster. What is the difference between writing a high level functional description

and describing the component systems of the disassembled blaster? I'm finding myself writing two really repetitive paragraphs about what pieces do what. 

Functional description

the component systems of the disassembled blaster

·         The nerf blaster is a toy gun manufactured by Hasbro.  It fires foam darts, discs or in some cases, foam balls. ·         They come in forms of pistols, rifles and light machine guns. ·         The clip system blasters only take streamline darts ·         Elite systems are compatible with regular and clip system blasters ·         A trigger actuates an electronic system inbuilt. ·         The batteries fire a timer chip which lights up leds and power lasers. ·         A sound effect module is operated by the timer to release the flash sound

·         Ammunition holders-hold ammunition ·         Foam darts-are usually rubber tipped for shooting ·         Barrel extension, act to direct and resemble a machine gun. ·         Flip up sight- to obtain line of sight ·         Dual mode light beam-to create the blaster effect ·         Stock- ·         Main blaster body-housing for blaster ·         Battery- to supply blaster with power ·         Barrel – to direct ammunition. ·         Butt cap-to close the barrel. ·         Leds-to give multicolor light. ·         Laser-to obtain directional sight line of ammunition. ·         Sound effect module-to generate blaster sounds. ·         Sites-for holding the blaster body ·         Handle- for holding by user

By functional description it refers highlighting the basic parts which are vital for operation,  here they include the triggering mechanism, the release of ammunition and the lighting of laser and led with a combination of sounds.

By component description it refers to the in depth explanation of every component in the blaster, it does not necessarily refer to the functional components but all materials and parts involved.
