Frame vs Packet
A packet and a frame are both packages of data moving through a network.
A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model.
Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet.
Layer 3 is the Network Layer. The best know Network Layer protocol is IP (Internet Protocol).
To move through a network, a packet is encapsulated into one or more frames, depending upon the MTU size.

- Understanding Frame Relay
Frame Relay is a protocol for transmitting data over a wide area network (WAN). It was designed to use across ISDN interfaces but it is now used over an assortment of other network interfaces. Once one becomes a master of frame relay design and configuration, it is much easier to obtain a strong understanding of [...]...
- Packet Sniffing
Packet sniffing is the act of intercepting and recording traffic that passes over a specific section or location on a network. As the data passes across the network, a packet sniffer application saves each packet for later use. Network administrators and law enforcement packet sniff for legitimate reasons, but rogue actors who use the captured [...]...
- Packet Radio
Packet radio is a type of digital data transmission which is most commonly used to link two computers together. It is based on the X.25 protocol used previously by amateur radio enthusiasts. The new generation of this technology as it is used in packet radio is known as the AX.25 data link layer. Packet radio [...]...
- Understanding Data Encapsulation
The sending and receiving of data from a source device to the destination device is possible with the help of networking protocols when data encapsulation is used. The data is encapsulated with protocol information at each OSI reference model layer when a host transmits data to another device across a network. Each layer communicates with [...]...
- Data Link Layer
The Data Link Layer is layer two of the OSI model. It resides above the Physical Layer and below the Network Layer. The Data Link Layer is responsible for communications between adjacent network nodes. Hubs and switches operate at the Data Link Layer. The Data Link Layer is logically divided into two sub-layers: The Media [...]...
