You are a software developer, and you're creating a multimedia streaming application. Data will be streamed from your streaming server to clients over IP networks. Which transport protocol should your application use to send data between the clients and the server? answer UDP TCP SNMP ICMP

UDP: UDP is preferred for multimedia streaming because it allows for lower latency transmission, which is crucial for real-time data like audio and video. Unlike TCP, UDP does not require acknowledgment of receipt of packets, making it faster and more efficient for streaming purposes where some loss of packets is acceptable and retransmitting lost packets is not desired.

Your system administrator shared a USB laser printer connected to your Windows 11 system so other users on the network could send jobs to it. A network user has sent a large job to the printer, but the print job has stalled. You try to delete the print job, but can't. Which of the following BEST describes the reason you cannot delete the print job? answer You do not have the Manage documents permission. You do not have the Print permission. You do not have the Manage this printer permission. You do not have the Manage network printers permission.
