This paper discusses how knowledge of computers can affect our daily personal life as well as in the workplace in Greece. Our research is concerned with how useful the knowledge of computers is in the everyday life and work of adults and attempts to investigate the interest of adults for learning computer programmes and different subjects via computers. The research took place from March 30 to April 10, 2015, in Lamia, Greece. Fifty individual adults aged 18-65 years old participated in this study. According to their answers it seems that they consider knowledge of computers essential; however, the same enthusiasm was not expressed when it came to learning through a computer.
