What is Data Link ( Data Link)?
Data Link is a network layer that regulates and controls data transmission on a computer network. They have tasks such as transmitting data into frames in the physical environment and identifying target devices.
What are the main tasks of the Data Link layer?
The main tasks of the Data Link layer are:
Creating a framework
addressing
Error check
Flow control
Armament (Collision Detection/Handling)
Which network protocols does the Data Link layer use?
The Data Link layer can use various network protocols such as Ethernet, Wi-Fi, Token Ring. These protocols provide different methods for the transmission and control of data.
What does the error check of the Data Link layer do?
Error control checks if the data is transmitted correctly. If a frame is faulty, it ensures that these errors are detected and corrected as needed.
What is the difference between the Data Link layer and the Network layer?
Data Link layer (Data Link Layer) determines how data is routed and delivered to target devices when editing data transmission on the physical environment.
Which devices use the Data Link layer?
The Data Link layer is hardwareally applied by network cards or network interface cards. These cards are located on network devices such as computers, routers, switches (switches) and network devices.
Why is the Data Link layer required?
The Data Link layer ensures that data is transmitted properly and reliably. It performs important tasks such as error control, addressing and framing in communication between different devices.
What would network communication be without the Data Link layer?
Without the Data Link layer, it becomes difficult to transmit data properly and redirect it to target devices, and reliability decreases. This layer allows the regulation of network communication.
What is the relationship between the Data Link layer and Security?
The Data Link layer has important security-related functions in the network. It can take security measures and prevent unauthorized access, especially at the framework level.
These questions and answers can help you gain a better understanding of the basic concepts and functions of the Data Link layer.
