Packet switching is a technique used in computer networks to transmit data as packets. Instead of reserving a dedicated communication channel for the entire duration of a transmission, packet switching breaks the data into packets and sends them independently. This method enables multiple users to sha...

A switch forwards a data packet based on the physical address (MAC address). For theIPprotocol, the switch is transparent. That is, when forwarding a data packet, the switch does not and needs not know theIP addressof the source or destination machine. It only needs to know the destinatio...
Packet sniffing is a method of detecting and assessing packet data sent over a network. It can be used by administrators for network monitoring and security. However, packet sniffing tools can also be used by hackers to spy or steal confidential data. The packet sniffing process is achieved by...
Packet sniffing is a technique whereby packet data flowing across the network is detected and observed. Network administrators use packet sniffing tools to monitor and validate network traffic, while hackers my use similar tools for nefarious purposes.
Packet Loss: This happens when data packets are either dropped or lost during transmission. A low packet loss is important for activities that require a consistent connection, like gaming or video conferencing. Kilobits per second (Kbps):This is a unit of measurement for data transfer speed. One...
