An Approach to Virtual Learning on the LAN Based System

Abstract

Over the past 20 years, computer networks have introduced unprecedented opportunities for language learners to access and publish texts and multimedia materials and to communicate in new ways within and beyond the classroom. Whereas computer­assisted language learning (CALL) refers broadly to a wide range of applications (e.g., tutorials, drills, simulations, instructional games, tests etc.), network­based Virtual Drawing (NBVD) refers specifically to the pedagogical use of computers connected in either local or global networks, allowing one­to­one, one­to­many, many­to­many communication. In addition to this high security are provided for secured data transmission.
