Updated 18 October 2026 · Fact-checked
Video conferencing is a live, two-way audio and video meeting between people at two or more locations, using cameras, microphones, screens and the internet. In business it is used for meetings, interviews, training, client presentations and board meetings. It saves travel time and cost but needs good internet and can suffer technical failures and security risks.
Understand Video Conferencing: Meaning, Uses and Limitations
1. Meaning. Video conferencing is a live meeting in which people at different places see and hear one another in real time through cameras, microphones, screens and speakers connected over the internet or dedicated networks. Participants can share screens, presentations and documents, and the meeting can be recorded. It joins the speed of the telephone with the personal touch of a face-to-face meeting.
2. Requirements. A device with camera and microphone; reliable high-speed internet; conferencing software or platform; a quiet, well-lit place.
3. Uses in business
- Meetings of managers and teams in different branches or countries.
- Interviews of candidates in other cities.
- Training sessions and webinars for staff and dealers in many regions.
- Client meetings, sales presentations and product demonstrations.
- Board and shareholder meetings, where permitted.
- Customer support and remote technical help.
4. Advantages. Saves travel time and cost; quick decisions; face-to-face interaction with expressions and gestures; brings many locations together; meetings can be recorded.
5. Limitations. Needs good internet and equipment; technical failures such as lag or poor sound; time-zone problems; less personal than a physical meeting; security risks such as uninvited participants and data leaks; screen fatigue.
6. Video conferencing versus e-mail
| Basis | Video conferencing | |
|---|---|---|
| Form | Live audio and video | Written message |
| Timing | Both sides present at the same time | Receiver can reply later |
| Record | Only if recorded | Automatic written record |
| Best for | Discussion, interviews, demonstrations | Documents, confirmations, evidence |
7. Choosing the tool. If real-time discussion and visual contact are needed, use video conferencing. If a written record or an attachment is the main need, use e-mail.

Example 3: Cost saving by video conference · 4 marks · Short answerHarder board level
Suppose a firm holds 12 review meetings a year. Each needs 5 managers to travel at Rs 9,000 per person including stay. The video-conferencing set-up costs Rs 2,40,000 a year. Calculate the saving and state one non-financial limitation.

- Risk 3: security of product data; reduce by invitation links and passwords.
Answer: Three advantages and three risks, each with a remedy.
Where students lose marks in Video Conferencing: Meaning, Uses and Limitations
The slips examiners see most often, and what to write instead.
Mistake: Defining video conferencing as a video call between two friends
The definition must be in a business context with real-time two-way audio and video across locations.

A live two-way audio and video meeting between people at different locations through the internet.
Do this: Use the four ideas: live, audio-visual, different places, internet.
Usually costs: 1-2 marks.
Mistake: Giving only advantages when asked for uses
Uses are situations; advantages are benefits.
Wrong working
Saves cost and time.
Right working
Used for board meetings, interviews of distant candidates, training of dealers.

Practice questions on Video Conferencing: Meaning, Uses and Limitations
Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.
Q1 · 1 mark · Very short answerBoard level
Name the equipment a participant needs to join a video conference from a computer.
Hint
See and speak.

A camera, a microphone, a screen, speakers and an internet connection.
Q2 · 2 marks · Short answerBoard level
State any two business uses of video conferencing.
Hint
Meetings and hiring.
Answer
Meetings of managers in different branches; interviews of candidates in other cities; training; client presentations (any two).
Q3 · 2 marks · Short answerHarder board level
Why can video conferencing be less suitable than an e-mail for recording a contract's terms?
Hint
Written record.
Answer
A video meeting leaves no automatic written record unless recorded, whereas an e-mail is a dated written message that can be stored and used as evidence.
Q4 · 4 marks · Short answerHOTS / competency
Suppose two branches, one in Mumbai and one in London, plan a call at 10 a.m. Mumbai time. Describe one limitation of video conferencing this shows, and a way to handle it.
Hint
Working hours.
Answer
Time-zone difference: 10 a.m. in Mumbai falls in the early morning of London, so the time may suit one side only. The managers can agree on a time that falls within working hours of both, or record the meeting for those who cannot attend.
Q5 · 4 marks · Short answerHarder board level
Explain how video conferencing combines the features of a telephone call and a face-to-face meeting.
Hint
Speed and personal touch.
Answer
Like a phone call, it is quick and connects people at a distance without travel. Like a face-to-face meeting, participants see expressions and gestures and can share screens and documents, so discussion is richer than voice alone.
