Describe the concept of Quality of Service (QoS) in WANs and its importance. How is QoS implemented to ensure efficient data transmission?

Expert Solution
Step 1: Introduction:

Quality of Service (QoS) is a critical concept in Wide Area Networks (WANs) that refers to the set of technologies and mechanisms used to manage and optimize the transmission of data. In a WAN, data traffic can vary significantly in terms of priority, sensitivity, and bandwidth requirements. QoS ensures that data is transmitted efficiently and reliably, with appropriate prioritization for different types of traffic. Here we will delve into the importance of QoS in WANs and its implementation for efficient data transmission.
