Author Interactive Whiteboards Explained
Nowadays Teachers are using Interactive Whiteboards to improve the quality of the instructions. Interactive Whiteboards make teaching sessions interactive and motivating. ;Interactive Whiteboards are digital whiteboards which are connected to projector and computer.
A projector projects the entire computer desktop on the active area of Interactive Whiteboards. Interactive Whiteboards are used in classrooms at all stages of education as a replacement of traditional whiteboards or flip charts.
Using the supplied software, Teacher can write, draw and annotate on its surface and navigates the computer functions from interactive whiteboard with finger or pen. Interactive Whiteboards allows teachers to record their session in video format which can be shared in to their classroom. An IR (infra-red) interactive whiteboard uses infra red beam to make the board touch sensitive.
Every school, college and university across globe is implementing Interactive Whiteboards into their classroom. Interactive Whiteboards opens up a world of opportunities for teachers to be innovative in their teaching and in student learning. Today interactive Whiteboards have become an integral part of learning environment.

OSPF Simulation – DR Election In-Depth (Visual, Interactive)
What is neighbor list?
Answer: Each OSPF router uses a neighbor list to track its neighbors discovered, their states, who is DR/BDR it has elected.
Answer: When a router floods a Hello, it wants to tell neighbors about its current list of neighbors by including its neighbor list in the Hello packet.
- Add the sending router to its neighbor list.
- Change the neighbor state of the sender to 2-way if Hello’s list of neighbors includes the receiver’s name.
- The router learns the sending router’s OSPF priority and Router ID. When a router receives a Hello, does it add all routers in Hello’s list of neighbors as its neighbors?
- R2 receives Hello from R1.
- R2 sends a Hello with a neighbor list that contains R1.
- R1 receives Hello from R2. R1 sees its name in Hello’s neighbor list.
This time, Hello’s list of neighbors contains R2.
- Only neighbor routers that are 2-way/full are eligible for election.
- Group eligible routers into 3 lists
- DR candidate list.
- BDR candidate list. E.g., routers who win as BDR in Hello
- Eligible. Routers not shown as DR, nor BDR in Hello.
- Elect BDR first. From the BDR candidate list, elect the highest priority router as BDR. If BDR candidate list is empty, then elect the highest priority-RID router from eligible list.
- Elect DR. In DR candidate list, elect the highest priority router as DR.
The simulation animates Hello flooding and neighbor lists changes.
Interactive Voice Response (IVR)
Evolution in Interactive Learning Technologies – Increasing Adoption
In classrooms, the use of interactive learning technologies is increasing and evolving continuously. To increase student comprehension and augment learning in the classrooms, instructors and instructional designers are using various learning technologies including Smart Interactive Whiteboards, Multimedia Projectors, Learning Management Systems (LMSs), Portable wireless Tablets, and Online Video Learning Portals, etc.
The use of Smart Interactive Board increases knowledge, excites students to learn more, and engages them more effectively using versatile course content. The Interactive Smartboard commands attention with large presentation area, support for interactive media content, and instant access to stimulating Web resources. Reaching students at different levels of learning, Smart Interactive Whiteboards can be controlled with a simple touch of a finger.
Interactive Smartboards enhance learning in all subject areas from History to Mathematics. As the user is interaction with the database is predetermined by what the IVR system will allow the user access to, IVR technology does not require human interaction over the telephone. Voicemail systems are different from IVR systems because they are a one way communication tool, but IVR systems attempt two way interaction with the caller. A fully functional IVR system should connect callers to their desired service promptly and with minimal flaws.IVR call flows are created in a variety of ways.
