Unit 6: networking

Task 3. Write down about Video conferencing and its tools
Video conferencing is an online technology that allows users in different locations to hold face- to-face meetings without having to move to a single location together. This technology is particularly convenient for business users in different cities or even different countries because it saves time, expenses, and hassles associated with business travel. Uses for video conferencing include holding routine meetings, negotiating business deals, and interviewing job candidates.

When a video conference is held for informal purposes, it is called a video call or video chat.
