What is the purpose of “QoS” (Quality of Service) in networking?
a) To prioritize certain types of network traffic for better performance
b) To assign IP addresses automatically
c) To compress data for faster transmission
d) To encrypt data for security
Answer:
a) To prioritize certain types of network traffic for better performance
Explanation:
Quality of Service (QoS) is a networking feature that prioritizes certain types of network traffic, such as video streaming, voice calls, or online gaming, to ensure better performance and prevent lag or interruptions.
QoS is especially useful in environments where multiple devices are sharing the same internet connection, as it helps maintain the quality of high-priority applications even when the network is congested with other traffic.
By managing and prioritizing traffic, QoS helps optimize network performance and improve the user experience, particularly for time-sensitive applications.
