What is Bandwidth?
Turkish: Bant Genişliği
Bandwidth is the maximum data capacity a connection can carry per second; it does not define perceived speed by itself.
What is Bandwidth?
Bandwidth is the amount of data a network connection can theoretically carry over a given time. It is usually expressed in Mbps or Gbps. More bandwidth means more carrying capacity, but perceived speed does not depend on this number alone.
Bandwidth, Throughput, and Latency
Bandwidth describes how many lanes the road has. Throughput is the amount of data actually delivered; congestion, packet loss, server capacity, and protocol overhead can make it lower than bandwidth. Latency is the time it takes for a request to travel and receive a response.
For example, a 1 Gbps connection helps with large downloads, but a small API request to a distant server can still feel slow because of high latency.
Business Use
Video streaming, file backup, e-commerce images, CDN traffic, and VPN links between offices all depend on bandwidth planning. In hosting or cloud services with traffic quotas, cost can also depend on bandwidth consumption.
A useful assessment looks at average traffic, peak hours, concurrent users, cache ratio, and data transfer cost together.
