What is POIT

     POIT stands for "Principles of Information Technology. This class I believe we will be learning about technology and how it changes our life on a daily basis. Also I think we will be learning how to code websites, edit websites, and create websites. Learning these new things will help us in the future when we are looking for a job. The world today is based on technology and knowing how to do lots of things with technology will give you the upper edge over others trying to get the same job you are trying to get in the future.

     In this class I want to be able to know how to make a website and know how to change basic things on the computer, like customizing your own desktop, or programming my own website. I also want to know how to work with a group of people, knowing the key board shortcuts would also help me too. In this class I think we will be learning how to create programs and know how to make a website. Also I think we will learn lots of things about technology.
