In computer networking , an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload. An Ethernet frame is preceded by a preamble and start frame delimiter SFD , which are both part of the Ethernet packet at the physical layer. Each Ethernet frame starts with an Ethernet header, which contains destination and source MAC addresses as its first two fields. The middle section of the frame is payload data including any headers for other protocols for example, Internet Protocol carried in the frame. The frame ends with a frame check sequence FCS , which is a bit cyclic redundancy check used to detect any in-transit corruption of data.

Ethernet switches link Ethernet devices together by relaying Ethernet frames between the devices connected to the switches. By moving Ethernet frames between the switch ports , a switch links the traffic carried by the individual network connections into a larger Ethernet network. Ethernet switches perform their linking function by bridging Ethernet frames between Ethernet segments. Ethernet bridging was initially defined in the The standardization of bridging operations in switches makes it possible to buy switches from different vendors that will work together when combined in a network design. At that time, Ethernet only supported connections to coaxial cables.
A frame is a digital data transmission unit in computer networking and telecommunication. In packet switched systems, a frame is a simple container for a single network packet. In other telecommunications systems, a frame is a repeating structure supporting time-division multiplexing. A frame typically includes frame synchronization features consisting of a sequence of bits or symbols that indicate to the receiver the beginning and end of the payload data within the stream of symbols or bits it receives. If a receiver is connected to the system during frame transmission, it ignores the data until it detects a new frame synchronization sequence. In the OSI model of computer networking, a frame is the protocol data unit at the data link layer.

However Datagram can also be used in a more general sense and refer to other layers link :. A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer andthe transporting network. Frames are units of data in the Link Layer e.

In this article, we are going to discuss about two terms frequently used in networking as a unit of data i. The crucial difference between frame and packet is that frame is the serial collection of bits, and it encapsulates packets whereas packets are the fragmented form of data and it encapsulates segment. Data link layer performs framing process. On the other hand, Network layer performs fragmentation of the data and create smaller chunks known as packets.
When discussing Ethernet data, the terms frame and packet are often used interchangeably. Frames and packets are the electronic containers that carry our data from point-to-point by navigating LANs and WANs and, as they both serve similar functions, their differences are often misunderstood. To simplify matters, imagine frames and packets as envelopes of information that are going to be sent from one person to another.
Especially after the introduction of different layered architecture of network communication. Irrespective of whether you are talking about network layer, transport layer or physical layer, the term PDU is generic and applies to all. Of Course different layers add different fields on top of data, but they can still be called PDUs. Being said that, according to OSI reference layered architecture, below is what is widely accepted. Network communication is actually message oriented.
The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2. Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations. Hubs provide a dedicated physical connection for every device, which helps reduce the possibility that a failure of one computer will cause all computers to lose connectivity. However, because a hub is still a shared bandwidth device, connectivity is limited to half-duplex. Collisions remain an issue as well, so hubs do not help improve the performance of the network.
