How the hardware affect the network performance?

Hardware plays a crucial role in network performance by determining the speed, capacity, and reliability of data transmission. Components such as routers, switches, and network interface cards (NICs) can limit or enhance bandwidth and latency. For example, high-quality routers with advanced processing capabilities can manage more connections simultaneously, while outdated hardware may become a bottleneck. Additionally, physical factors like cabling quality and network topology also influence overall performance, affecting signal strength and data integrity.
