What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.).

How to protect your privacy on WhatsApp?

Nowadays WhatsApp is in everyone's phone. It has become an essential app, through which we get facilities like chat, call, photo-video sharing.

In this blog, we will tell you how you can keep your privacy safe on WhatsApp, that too in simple language.

1. Update your privacy settings

WhatsApp has a special feature called Privacy Settings . You can secure your information by setting it correctly. For this -

  • Open WhatsApp.
  • Go to Settings.
  • Click on Privacy option.

Here you can decide who can see your profile photo, last seen, about, status and live location –

  • Everyone
  • Only your contacts
  • My Contacts Except
  • Or Nobody

Tip: Select "My Contacts" or "My Contacts Except" to increase your privacy.

2. Turn on Two-Step Verification

Two-step verification is a strong security measure that makes your WhatsApp account more secure. To turn it on -

  • Go to WhatsApp Settings.
  • Go to Account.
  • Click on Two-step verification and set a 6-digit PIN.

This will allow whenever someone logs into your account, they will have to enter this PIN.

3. Do not show your profile photo to everyone

Sometimes unknown people can harass you just by looking at your profile photo. It would be better to show your profile photo only to your contacts.
Privacy Settings > Profile Photo > My Contacts

4. Lock WhatsApp

WhatsApp now has an inbuilt App Lock feature.

  • Settings > Privacy > Fingerprint Lock
  • Turn it on.

With this, your WhatsApp will open only with your fingerprint.

5. Beware of Unknown Numbers

If you receive a message from an unknown number, block or report it immediately. Especially if someone sends a suspicious link, never click on it.

  • Open the chat > ​​Click on the 3 dots above > More > Block or Report
6. Turn off automatic media downloads

Sometimes in groups or unknown chats, you may get such videos and photos which can be dangerous. To avoid this -

  • Settings > Storage and Data > Media Auto-Download
  • Turn off everything (No Media).

Now no file will be downloaded without your permission.

7. Do not show status to everyone

If you don't want everyone to see your status, you can limit it too.
Privacy Settings > Status > My Contacts Except or Only Share With
will make your status visible only to those you want.

8. Use WhatsApp Web properly

If you ever use WhatsApp Web, don't forget to log out when you're done.

  • WhatsApp > Linked Devices > Active Devices
  • Logout unnecessary devices from here.
9. Avoid fake messages and forwards

Many times fake messages are forwarded, which contain wrong links or incorrect information. Never forward any suspicious messages or trust them.

10. Avoid being added to groups without permission

If anyone adds you to any group, it can be a violation of privacy. To control this -

  • Privacy Settings > Groups > My Contacts or My Contacts Except
    Now no stranger will be able to add you directly to the group.
Final Advice

Keep updating WhatsApp from time to time as new updates always add security features. Also, keep a good antivirus in your phone so that no virus or spyware can steal your chats.

conclusion

Maintaining privacy on WhatsApp is not a difficult task. You just need to pay a little attention to your settings and use the app smartly. Remember, digital security is just as important as real-world security .
