QoS is Quality of Service. Basically it prioritizes VOIP calls.

QoS
There are many approaches to using voip on your network. you can simply treat the voice traffic as regular data traffic. this approach can lead to poor quality voice calls however. you can also use qos (quality of service) and vlans to better design your voice infrastructure. The easiest is to subscribe to a VOIP provider.

QoS stands for Quality of Service. The most common complaints against VOiP communications are quality and reliability. The type of hardware one uses can greatly impact the quality.
Quality of Service (QoS) provides several essential benefits, including prioritized network traffic management, which ensures that critical applications receive the necessary bandwidth and low latency. It also enhances overall network performance by reducing congestion and minimizing packet loss. Additionally, QoS facilitates efficient resource allocation, allowing for better user experiences in applications such as VoIP and video streaming.
Even though IP telephony and VoIP are used interchangeably, IP telephony refers the ability of users to mix-and-match third-party hardware and software.It is a best-effort network without fundamental Quality of Service (QoS) guarantees.
QoS mapping for a wireless network - Mapping of QoS names of one protocol (e.g GSM GPRS) to the names of another protoco (e.g. WAP 3GPP.) More genrally, mapping of one QoS lassification to another.
Quality of Service (QoS) is essential for network traffic that is sensitive to delays, jitter, and packet loss, such as voice over IP (VoIP), video conferencing, and online gaming. These applications require consistent bandwidth and low latency to function effectively. Additionally, streaming media and real-time data services also benefit from QoS to ensure a smooth user experience. Implementing QoS helps prioritize this critical traffic over less sensitive data, like file downloads or web browsing.
VOIP is Voice Over Internet Protocol. It is a technique for converting an analog telephone connection to digital, sending it over a computer network, and converting it back to analog at the other end. The typical bandwidth required for a telephone conversation is 56kbps. In fact, this is how the telephone companies work. What we call VOIP is an extension of that technology to allow use within a business, or to allow telephone calls over the Internet. In a business application, the network architecture usually supports a QOS (Quality of Service) parameter that gives precedence to VOIP traffic over data traffic. Often, with Internet telephone support, the QOS is not set nor supported, making the conversation subject to breaking up. Just like some cellphones.
