What does Frank's Computer represent?

Frank's computer symbolizes illiterate, unmotivated youth to Mum. She cannot fathom how or why anyone would spend so much time playing a video game. She thinks young people should be reading books and watching movies instead of playing games. Frank's computer is especially a sore spot for Mum because he lies and cheats to use it even when he is grounded. Convinced of his addiction to gaming, Mum throws his computer out the window.
