that's a very broad topic. the obvious influence is the personal computer and the many things you can do with it. it provides entertainment, allows users to write essays, increases productivity with software (think excel, powerpoint, photoshop, etc.). knowledge of this software creates jobs and helps run the economy, albeit in a very slow way recently. those companies using that software affect your life in many ways. think of the bank, the grocery store inventory database systems, streetlights, your car, etc. The generation of electricity relies on technology and this allows you to watch tv at night, turn on lights when it's dark and power your computer to play games.
you could even use that loop to show how technology encompasses our lives. you might want to center it around your life since the essay prompt is "How technology influences [your] life."
btw, which campuses are you applying to and for what major(s)?
