In a LAN, the use of a networking switch can minimize problems with packet sniffing by implementing IPsec at layer 3which encrypts transmissions across the network link.
(These damn ITT tech questions can be a pain sometimes, eh?)
Packet sniffing as a legal activity is usually defined by the corporate or company policy. Most institutions will ban the activity unless your job role requires it. Outside of a company network there is usually no restriction on packet capturing/sniffing. Packet sniffing is also done by certain types of programs, such as IDS or IPS devices/systems.
Packet sniffing is usually sniffs wireless transmissions. Sniffing is the interception of data or packets. The person who is suppose to receive the information still does but a third party has the ability to eavesdrop read the data. Packets can range from harmless info like your latest homework assignment or other more sensitive information like your Bank statement. The method to avoid a person sniffing your data sent wirelessly is to encrypt the data with modern day encryption algorithms.
There is a program called wireshark used for packet sniffing, if you understand a bit about networking this should be an invaluable tool.

Packet forwarding in simple terms is the forwarding of packets from one node to another from networking point of view. For example, a router or a switch. These networking devices make routing devices with the help of their routing tables and then select an outgoing interface. After that they make some changes in the packet header and push (forward) the packet to the selected interface. In case you don't know the meaning of packet. Packer is the smallest unit of size in networking. Different networks has different packet size. For example, in ATM Networks the packet size is of 53 Bytes.
The loss of data packets during transmission.
Passive wiretapping, usually on a local area network, to gain knowledge of passwords. Attempt by an unauthorized entity to gain access to a system by posing as an authorized user is spoofing
Using packet tracer. It is basically a software which helps you simulate the network.
IPX/SPX (Internetwork Packet Exchange/Sequenced Packet Exchange) is not supported on internet.
Packet
A ghost packet is typically a term used in networking to refer to a packet that appears to be present on the network but does not actually contain any data or payload. This can be a result of various network issues or anomalies that cause the packet to be improperly handled or displayed. Ghost packets can sometimes indicate network errors or security threats.
If you think the NSA is not fully capable of sniffing every single internet packet for interesting words like "drugs", then you're delusional.
