What is UX/UI design?

User Interface is the point of human-computer interaction and communication in a device. It can also be simplified as what the user would equip to interact with a website 

This could include:

• Mouse to navigate the cursor through your screen

There are also various different user interfaces which include: 

• Graphical user interface 
• Command-line interface 
• Menu-driven interface 
• Touch-user interface as displayed on your phone 
• Voice user interface like the voice recording in your social messaging apps 
• form-based user interface like the contact page on a website 
• natural language interface
