Answer:

1)Videoconferencing (or video conference) means to conduct a conference between two or more participants at different sites by using computer networks to transmit audio and video data.

For example, a point-to-point (two-person) video conferencing system works much like a videotelephone.

2)A search engine is a website through which users can search internet content. To do this, users enter the desired search term into the search field. Thesearch engine then looks through its index for relevant websites and displays them in the form of a list.
