The main difference is the means by which each is accomplished. A traditional illustration is a sketch, painting, drawing, etc. A photo illustration is just that - a photo.
A technical drawing is drawn precisely to a scale. Measurements taken from the drawing can be scaled up to produce or build a full size structure or machine, etc. A freehand drawing could be a simple sketch, detailed drawing, rough doodle, of a subject and is classed as a picture.
The main differences between sketch paper and drawing paper are the weight and texture. Sketch paper is lighter and has a rougher texture, making it ideal for quick sketches and experimentation. Drawing paper is heavier and smoother, providing a better surface for detailed and finished artwork.
Sketch paper is typically lighter weight and has a rougher texture, making it ideal for quick sketches and preliminary drawings. Drawing paper is heavier weight and has a smoother surface, making it better suited for detailed and finished drawings that require more precision and durability.
An isometric is more specific
Sketching is a quick drawing done to put your ideas down, it's often lineart and very messy but captures the general idea. Rendering is the process of refining and adding shape and form to a drawing/painting in the terms of shadows. Ie a slightly more refined process.
