Understanding Bandwidth
Bandwidth measures the maximum rate of data transfer across a network path. It's typically measured in bits per second (bps), with common units being Mbps (megabits per second) and Gbps (gigabits per second).
Bits vs Bytes
Network speeds are usually measured in bits, while file sizes are measured in bytes. Since 1 byte = 8 bits, to convert:
- 100 Mbps = 12.5 MB/s (divide by 8)
- 1 Gbps = 125 MB/s
- 10 Gbps = 1.25 GB/s
Common Bandwidth Standards
| Connection Type | Typical Speed | Use Case |
|---|---|---|
| Fast Ethernet | 100 Mbps | Legacy LAN |
| Gigabit Ethernet | 1 Gbps | Standard LAN |
| 10G Ethernet | 10 Gbps | Data center, backbone |
| 25G Ethernet | 25 Gbps | Server connections |
| 40G Ethernet | 40 Gbps | Spine/leaf networks |
| 100G Ethernet | 100 Gbps | Data center spine |
