Pulse shaping, zero stuffing, scrambling). • Transmits a sequence of electrical symbols that represents the frame received from the data link layer. When receiving, the physical layer: • Receives a sequence of electrical signals. • Interprets the signals as 1s and 0s. , unstuffs zeros, unscrambles). • Passes a clean logical symbol stream to the data link layer. Peer-to-peer communication consists of the signals that represent the total frame passed between Systems 1 and 2. S. Department of Defense (DoD) was developing a data communication network.
Confirms that the process is completed. 2 Transport Layer Two modes of operation are possible in the transport layer. The header may support a simple, connectionless procedure called User Datagram Protocol (UDP), or may support a connection-oriented procedure called Transmission Control Protocol (TCP). The transport layer PDU is called a segment or message. When sending in the connectionless mode, the transport layer: • Accepts the APDU from the application layer. • Records both source and destination ports.
How does the receiver determine the presence of errors? How does the receiver determine and keep track of the frame format? How does the receiver distinguish between control data and message data? How does the receiver notify the sender of congestion? Open Systems Interconnection Model The general problem of communication between cooperating dissimilar hosts situated on interconnected, but diverse, networks was studied by committees under the sponsorship of the International Organization for Standardization (ISO).
