Computer technology has changed the ways we work, learn, interact and spend our leisure time. Computer technology has changed every aspect of our daily life--how and where we get our news, how we order goods and services, and how we communicate. This study investigates some of the significant issues concerning the use of computer technology resources in the EFL classrooms. The first aim of the study is to discuss the advantages of the use of computer technology into the classroom. The second aim is to explain the successful integration of computer technology into the classroom. The third aim is to elaborate teachers' roles in computer technology integration. The last aim is to mention contribution of computer technology to English Language Teaching and learning. The review of the related literature shows that simply introducing computer technology resources does not guarantee teachers' use of these in practice. Knowledge of EFL teachers' roles about teaching, learning and computers affords them the opportunity to design and implement EFL instruction.
