The Answer is 1. Bandwidth: Bandwidth is a crucial QoS parameter for multimedia transmission as it determines the amount of data that can be transmitted over a network in a given amount of time. For example, in video streaming applications, the bandwidth directly affects the video quality and resolution. Higher bandwidth allows for higher resolution and smoother playback, while lower bandwidth may result in pixelation and buffering.

2. Latency: Latency refers to the delay between the transmission of data and its reception. In real-time communication applications such as video conferencing or online gaming, low latency is essential for a seamless user experience. High latency can result in delays in audio and video synchronization, as well as lag in gameplay.

3. Jitter: Jitter is the variation in packet arrival times, which can lead to inconsistent playback in multimedia applications. For example, in voice over IP (VoIP) applications, jitter can cause disruptions in audio quality, such as choppy or distorted sound. In video streaming, jitter can result in buffering and uneven playback.

The values of these parameters are affected by the application data in the following ways:
- Bandwidth: The resolution, frame rate, and compression of multimedia data directly impact the required bandwidth. Higher resolution and frame rate demand more bandwidth, while efficient compression can reduce the bandwidth requirements.
- Latency: Real-time applications with high data volumes, such as virtual reality or augmented reality, require low latency to ensure a seamless user experience. The complexity of the application data and the distance between the sender and receiver can affect latency.
- Jitter: The packet size and transmission frequency of multimedia data can influence jitter. Larger packets and inconsistent transmission intervals can contribute to increased jitter, affecting the quality of the multimedia transmission.
