About :

The Network+ comprehensive course is one of the most reputable training courses in the field of computer networks that helps users become fully familiar with the principles and concepts of networking. One of the key topics in this course is the OSI model and its various layers. The Data Link Layer, as the second layer of the OSI model, plays a vital role in establishing network communications. This layer is responsible for managing communications between two neighboring devices and also detecting and correcting communication errors. The Data Link Layer in the OSI model includes two important sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The MAC sublayer deals with how devices access physical media such as cables and optical fibers, and the LLC sublayer is responsible for regulating logical communications between devices. In the Network+ course, you will become familiar with these sublayers and how they work, which will help you provide stable and secure network communications. In the Data Link Layer training, you will learn about important protocols such as Ethernet and Wi-Fi that operate at this layer. These protocols manage how data is packaged for transmission, identify destination devices, and detect and correct possible errors. By learning these topics in the Network Plus course, you will gain the necessary ability to manage and configure various networks and can become a professional expert in the field of computer networks.
