• Practice Questions & Answers
Question 1: What is WhatsApp?
Answer: WhatsApp is a free messaging and calling application that allows users to send text messages, make voice and video calls, share media files, and communicate with contacts worldwide. It uses internet connection and provides end-to-end encryption for security. Founded in 2009, it's now owned by Meta and used by over 2 billion people globally.
Question 2: What does end-to-end encryption mean in WhatsApp?
Answer: End-to-end encryption means that only you and the person you're communicating with can read or listen to the messages, calls, photos, and videos you send. The content is encrypted on your device and only decrypted on the recipient's device. Not even WhatsApp can access or read your encrypted messages. This provides maximum privacy and security for your communications.
Question 3: What is the difference between WhatsApp and WhatsApp Business?
Answer: WhatsApp is designed for personal use, while WhatsApp Business is designed for small businesses to communicate with customers. WhatsApp Business offers additional features like business profile, product catalog, automated messages (greeting, away messages), quick replies, labels for organizing customers, and statistics. Both versions are free, but serve different purposes.
Question 4: How many members can be added to a WhatsApp group?
Answer: A WhatsApp group can have up to 1024 members. Previously, the limit was 256, but WhatsApp increased this limit to allow larger communities to communicate. Group admins can control who sends messages, who can edit group info, and manage member permissions.
Question 5: What do the different tick marks mean in WhatsApp?
Answer: The tick marks indicate message status:
- Single Gray Tick (✓): Message sent to WhatsApp server
- Double Gray Ticks (✓✓): Message delivered to recipient's phone
- Double Blue Ticks (✓✓): Message read by recipient
Note: You can disable read receipts in privacy settings, but this will also prevent you from seeing when others read your messages.
Question 6: How can you backup your WhatsApp chats?
Answer: To backup WhatsApp chats:
- Android: Go to Settings → Chats → Chat backup → Backup to Google Drive
- iPhone: Go to Settings → Chats → Chat backup → Back Up Now (backs up to iCloud)
You can choose backup frequency (daily, weekly, monthly, off) and whether to include videos. Make sure you're connected to WiFi for large backups to avoid data charges.
Question 7: What are disappearing messages in WhatsApp?
Answer: Disappearing messages is a privacy feature where messages automatically delete after a set time period. You can choose 24 hours, 7 days, or 90 days. Once enabled, new messages in that chat will disappear after the selected duration. This helps keep chats clutter-free and protects privacy. However, the recipient can still take screenshots or forward messages before they disappear.
Question 8: Is WhatsApp free to use?
Answer: Yes, WhatsApp is completely free for personal use and for small businesses using WhatsApp Business app. There are no subscription fees, message limits, or hidden charges. However, you need internet connection (mobile data or WiFi), and your mobile operator may charge for data usage. Only the WhatsApp Business API for large enterprises has associated costs.
Question 9: How do you make a group video call on WhatsApp?
Answer: To make a group video call:
- Method 1: Open a group chat → Tap video call icon
- Method 2: Go to Calls tab → Tap + icon → Select contacts → Tap video call icon

You can add up to 32 participants in a group video call. Make sure you have stable internet connection for best quality.
Question 10: What is WhatsApp Status and how long does it last?
Answer: WhatsApp Status is a feature that allows you to share photos, videos, GIFs, or text updates with your contacts. Status updates disappear automatically after 24 hours. It's similar to Instagram Stories or Facebook Stories. You can control who sees your status through privacy settings (everyone, contacts only, or specific people). You can also see who viewed your status by tapping on it.
