Layer 2 addressing not required for this topology
Data Link
Data Link
The role is to transfer frames to packets
The data link layer is responsible for ensuring the trustworthy transmission of data across a physical link. It handles physical addressing, line discipline, network topology, error notification, and ordered delivery of frames. By managing these functions, the data link layer ensures that data packets are reliably transmitted between directly connected devices.
* addressing * error detection * frame delimiting
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.
The Internet Protocol (IP) provides routing of data from the source to a destination by defining the packet structure and addressing scheme. It operates at the network layer, facilitating the movement of data between the data link layer and the transport layer. IP routes packets of data across interconnected networks, ensuring they reach their intended remote destinations. Its primary function is to handle addressing and routing, enabling effective communication across diverse network architectures.
The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.
addressing modes helps the programmer to store or retrieve the data which is stored in any part of the data memory by addressing mode specified in the program.
Data can be accessed from memory by using the addressing modes, 8085 has 5 addressing modes namely,1. Immediate addressing mode 2. register addressing mode 3. direct addressing mode 4. indirect addressing mode 5. implied addressing mode
1.Explicit Addressing 2.Implicit Addressing 3.Link Based Addressing
