A sniffer is like a digital bloodhound in the world of computer networks. Picture your data as tasty treats, and the sniffer is on the prowl, sniffing out those delicious bytes as they travel through cyberspace.

A sniffer is a tool that sniffs out data packets as they whizz by on a network. It’s like having a detective pooch to help find clues or catch cyber wrongdoers. While sniffers can be used for good (like troubleshooting network issues), they can also be misused by sneaky hackers to intercept your private info. So, keep your data safe from these nosy sniffers by using encryption and secure connections. Remember, a well-trained sniffer can be a best friend or a pesky intruder – it all depends on whose leash it’s on!
