What defines a segment in a network?

A segment in a network is defined as a section that is bounded by routers or switches. This concept is critical in understanding how networks are organized and segmented for efficient data transmission and management.

In networking, segmentation helps to create distinct broadcast domains. Each segment can operate independently, reducing the overall amount of traffic on the network and improving performance. Routers or switches serve as boundaries that manage the flow of data between segments, allowing for isolation and enhanced security controls. By segmenting a network, administrators can also implement varying security policies and performance management techniques tailored to the specific needs of different areas of the network.

This understanding of network segmentation is fundamental for network design, maintenance, and troubleshooting, ensuring that data can be segmented logically based on function or department, which significantly impacts overall network efficiency.
