Packets in computer communications can be defined as a quantity of data of limited size. In Internet all traffic travels in the form of packets, the entire file downloads, Web page retrievals, email, all these Internet communications always occur in the form of packets. In the internet, packet is a formatted unit of data carried by a packet mode in computer network Packets are the base of all data sent on the internet, yet they are often used insecurely. Tampering with live packets and the process it takes in order to alter packets traveling along the network are getting easier. Packet sniffing is commonly described as monitoring packets as they go across a network. Packet sniffers are typically software based, but can be hardware pieces installed directly along the network. Sniffers can go beyond network hosts that are seen in local area networks (LAN) that only handle data that is sent specifically to them.
