The data link layer is composed of two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The LLC manages communication between the network layer and MAC, providing framing, error detection, and flow control, while the MAC layer controls how data packets are placed on and retrieved from the physical medium. It ensures proper access to the shared medium, manages addressing and encapsulation, and handles collision detection and avoidance in network environments. By performing these functions, the data link layer ensures reliable and efficient data transfer over the physical network.

What layer supports functions such as Directory Services?
The layer that supports functions such as Directory Services is the Application Layer. This layer provides services directly to user applications, facilitating functions like authentication, resource management, and data storage. Directory Services, such as LDAP (Lightweight Directory Access Protocol), operate within this layer to manage and provide access to directory information.
Which OSI layer ordered data reconstruction services?
transport layer
How does a TCP work?
TCP/IP is composed of layers, wherein each layer is responsible for performing certain operations on the data it receives and passing it to the higher layers. Each layer deals with certain issues related to the transmission of data and renders certain services to its higher layers.
What services do the data mining company provide?
Data Mining companies provide such services as mining for data and mining for data two electric bugaloo. They will often offer to resort to underhanded tactics to mine said data.
What layer correct errors in osi model?
The Transport Layer and Data Layer can provide error detection and correction at the different levels of data transmission. Network layer can also correct errors if it detects them.
Which OSI layer offers reliable connection-oriented data communication data services?
application presentation session **transport network The transport layer of the osi model
Layer provide data flow and sequence number?
The transport layer provides flow control and sequencing.
What services does the website IRI provide?
The webpage IRI provides a range of services in integrating and sourcing data. They help companies and individuals with data migration and data masking services.
It is difficult to generalize about protocols because they vary so greatly in purpose but what properties do application protocols display?
The Application layer uses protocols that are implemented within applications and services. While applications provide people with a way to create messages and Application layer services establish an interface to the network, protocols provide the rules and formats that govern how data is treated.
How networking media devices and software work together to provide data networking services?
How networking media devices and software work together to provide data networking services?
Why Bridges operate at Layer 2?
Layer 2 of the OSI model, the Data Link Layer is composed of two sublayers, the lower being the MAC layer that regulates how computers access information on a network and transmit it. A bridge connects two networks, or two sections of a LAN, and works at the Data Link Layer to regulate it.
What are true statements about transport layer protocols?
**The TCP transport layer protocol uses windowing and acknowledgments for reliable transfer of data. **The TCP and UDP port numbers are used by application layer protocols. **The TCP transport layer protocol provides services to direct the data packets to their destination hosts.
