9 Best Of What Is Framing And Its Types In Computer Network Best Wallpaper JPG. Oct 03 2017 Ethernet frame starts with Preamble and SFD both works at the physical layer. The last field is CRC which is used to detect the error.
In this the stream of bits are divided into manageable bit units called frames. As the name suggests it is an invisible bridge in the computer network. Example ATM cells.
Upper-layer protocols are generally designed to interface with any of these protocols and framing methods.
Dec 31 2018 High-level Data Link Control HDLC is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Ethernet token ring frame relay ATM and other data link technologies use their own framing standards ATM frames are actually called cells. Frames also help to determine how data receivers interpret a stream of data from a source. However these bits must be framed into discernible blocks of information.
