What about your audience must you understand before beginning to create an effective design?

The design is about the audience of consumers, viewers, and users. So, before  you start creating your design you must first understand your audience.
You must know the gender, the habits and the lifestyle of the audience.
You should answer the questions: What kind of things your customers do? What kind of music do they listen to? What products do they use? How old are they?

Hacking is when someone without the right to do so, goes into your accounts or stuff and takes over it and you can’t get back on it.
