What are the differences and connections between powerpoint, flash and photoshop?

Hello, the same point: they are all picture, text and animation processing software produced by ADOBE.

Difference: 1.powerpoint belongs to the category of office software and is generally used for daily teaching and office meetings. You can make simple animated slides that combine graphics and text, and you can also combine multiple slides to play as needed, which is generally used for teaching and meetings. What you usually see on the projector in a meeting or class is made by powerpoint.

2.flash, which is a special two-dimensional animation software. Some small animations that we usually see on the web page are made with this software, and some cartoons, such as Pleasant Goat and Big Big Wolf, are made with it.

3.PS is a special bitmap synthesis software. Commonly used in graphic design and post-processing of photography. It usually handles some billboards or leaflets and photos of the studio.

To make a web page, it is difficult to produce the desired effect with only one software, and it is often used in combination with several softwares. Flash and photoshop are particularly closely combined with web page making.

I hope I can help you and adopt it. Thank you.
