Abstract
Existence of language laboratory for students has an important role in improving communication skills both in oral and written. Development of Information and Communication Technology (ICT) moves language laboratory toward digital one. One feature that is implemented in digital language laboratory system is remote presentation. This feature enables sending teacher slide across the network, to every student terminal by using communication based on client server architecture. The sending of slide is done sequentially and so, introduces delay on receiving slide progressively. This research is aim to measure the largest delay introduced in sending slide to clients in the digital language laboratory system that has been implemented in previous research. © 2012 IEEE.
