What is the difference between digicam and camcorder?

Could you elaborate on the key distinctions between a digicam and a camcorder? I'm particularly interested in understanding the technical aspects that set them apart. For instance, does the digicam excel primarily in still photography while the camcorder focuses more on video recording? Are there any significant differences in terms of image quality, resolution, or zoom capabilities? Additionally, how do they differ in terms of portability and ease of use? I'm looking for a concise yet comprehensive explanation that highlights the key differences between these two devices.
