In Hack the Stack, Protocol Analyzers. Protocol analyzers (or sniffers) are powerful programs that work by placing the host system’s network card into promiscuous mode, thereby allowing it to receive all of the data it sees in that particular collision domain. Passive sniffing is performed when a user is on a www.portal-1.ru using a hub, all traffic is sent to all ports; thus, all a . Nov 02,  · Each layer usually has more than one protocol options to carry out the responsibility that the layer adheres to. TCP/IP is normally considered to be a 4 layer system. The 4 layers are as follows: Application layer; Transport layer; Network layer; Data link layer; 1. Application layer. This is the top layer of TCP/IP protocol suite. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent.
