World of Computer Networking Your CCNA start - Latency

The video tutorial discusses the concept of latency in networks, emphasizing its importance in real-time applications like video and audio transmission. Latency is defined as the one-way delay in data transfer between devices, influenced by various factors such as queuing, processing, transmission, and propagation delays. The tutorial explains how each layer of the TCP/IP model contributes to latency and provides detailed insights into different types of delays. It concludes with a brief mention of round trip time, highlighting the need to understand latency for optimizing network performance.
