What is the practice called when a network is divided into smaller segments to reduce collisions and improve performance?

• A. Routing
• B. Switching
• C. Segmentation
• D. VPN

Answer: (C)

Segmenting a network into smaller portions reduces contention by limiting how many devices share the same communication channel. When many devices compete on one segment, data collisions can occur, forcing retransmissions and slowing everything down. By dividing the network, you shrink the collision domains, so fewer devices contend for access at once and performance improves. In practice, switches create separate collision domains for each port (and VLANs can further segment groups of devices at the data link layer). Routing and VPNs serve different purposes—routing connects separate networks, while a VPN provides secure remote access—so they don’t describe this particular practice.
