대역폭

정의

통신 채널의 최대 데이터 전송 용량으로, 보통 초당 비트(bps, Mbps, Gbps)로 측정한다.

설명

Bandwidth represents the theoretical ceiling, not the actual speed achieved in practice. A fiber link may have 1 Gbps bandwidth but deliver less throughput due to protocol overhead and network congestion. The term originates from radio engineering, where it described the range of frequencies a channel could carry. Consumer broadband plans typically offer 100 Mbps to 1 Gbps downstream bandwidth.
