Evaluate the scalability and reliability of networks : Application types and network performance

The video discusses how network performance affects user experience across different application types. Batch applications like FTP require minimal user interaction and can adapt to varying bandwidth. Interactive applications need more human intervention, with response times being crucial but not as critical as in real-time applications. Real-time applications, such as voice and video, demand high-quality service and low latency to ensure seamless human interaction. Quality of Service (QoS) is essential in busy networks to maintain the performance of voice and video applications.

Which type of application typically requires minimal user interaction and can vary in bandwidth usage?

• Streaming applications

• Batch applications

• Interactive applications

• Real-time applications

What is a key characteristic of interactive applications?

• They involve waiting for a response due to human interaction.

• They need high bandwidth at all times.

• They require no user interaction.

• They are unaffected by network delays.

Why is response time important in interactive applications?

• Because it ensures data is not lost.

• Because it determines the amount of bandwidth used.

• Because it affects the completion of transactions.

• Because it is critical for real-time communication.

What is crucial for real-time applications like voice and video?

• High storage capacity

• High bandwidth and low delay

• Minimal user interaction

• Batch processing capabilities

What mechanism is often implemented to improve user experience in busy networks for real-time applications?

• Increased storage

• Quality of Service (QoS)

• Interactive feedback
