Interactive white boards (IWB) are large touchscreen displays connected to computers, allowing users to interact directly with digital content. Normal chalk boards (NCB) are traditional slates that use chalk. While IWBs allow content to be saved, shared digitally, and incorporate online resources, they require technology skills and preparation. Both have their place in classrooms and offices, with the goal of integrating information technologies into new educational activities and experiences.

3. Introduction
Today radical changes are introduced in
cultural and social life by computers that

the internet that connect computer and

information and communication
technologies have also altered the traditional
classroom environment and instructional
methods.

10. CONCLUSION
All boards whether they are chalk, white or
interactive have their share of advantages and
disadvantages. The use of all these boards
should not be seen as a tool that increase
academic achievement, but one that brings
information and communication technologies
to the class rooms and leads to new teaching
and learning activities.
