Frame (networking)
open-in-new
<p>A frame is a digital <a href="/facts/Data_transmission/1yAhaANd">data transmission</a> unit in <a href="/facts/Computer_networking/3w5RM99p">computer networking</a> and <a href="/facts/Telecommunications/vxoj1cxR">telecommunications</a>. In <a href="/facts/Packet_switched/olDlDP1R">packet switched</a> systems, a frame is a simple container for a single <a href="/facts/Network_packet/xCYf8SJu">network packet</a>. In other telecommunications systems, a frame is a repeating structure supporting <a href="/facts/Time-division_multiplexing/tv7bMh1v">time-division multiplexing</a>. </p><p>A frame typically includes <a href="/facts/Frame_synchronization/uCRQnA4J">frame synchronization</a> features consisting of a sequence of bits or symbols that indicate to the receiver the beginning and end of the <a href="/facts/Payload_(computing)/zN2Pgfq6">payload data</a> 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. </p>
