What is the difference between bandwidth and latency in networking?
- A.They measure the same thing, because the physical layer is responsible for logical addressing and for choosing the route a packet takes, while the network layer only encodes voltage transitions onto the medium, and neither layer exchanges any information with the other because each terminates an independent session with the remote host
- B.Bandwidth is the maximum data transfer capacity of a connection (measured in Mbps/Gbps), while latency is the time delay for data to travel from source to destination (measured in milliseconds) - high bandwidth with high latency means lots of data can transfer but with delay; security tools like VPNs and proxies add latency
- C.Latency measures speed
- D.Bandwidth measures delay
Why B is correct
Bandwidth: capacity (how much data per second), measured in Mbps/Gbps. Latency: delay (how long to arrive), measured in ms. Throughput: actual data rate (affected by both). Security relevance: VPNs/proxies add latency, IDS/IPS must handle line-rate bandwidth, and DDoS targets bandwidth capacity.
