Discuss the concept of a protocol analyzer (packet sniffer) in the OSI model. At which layer(s) is it most commonly used, and what information can it provide?
In the realm of network management and analysis, the protocol analyzer, often referred to as a packet sniffer, stands as an indispensable tool. Operating at the heart of the OSI (Open Systems Interconnection) model, this technology plays a pivotal role in capturing, dissecting, and decoding the intricacies of network traffic. It provides invaluable insights into the inner workings of data packets, offering a window into the behavior of devices, protocols, and applications traversing the network. In this exploration, delve into the concept of a protocol analyzer, examining the layers of the OSI model at which it is most commonly employed and the wealth of information it can unveil, empowering network administrators and analysts alike.
