A common misconception in computer networking is that increasing bandwidth will always reduce latency.

Bandwidth defines the volume of data that can travel across a link per second, whereas latency refers to the delay in transmission. Because bandwidth and latency measure different properties, a high-bandwidth connection that experiences slow response times will still feel laggy.

Bandwidth Versus Latency

Several misconceptions exist regarding network privacy and device addressing:

* **HTTPS Privacy**: While HTTPS encrypts page contents, it does not conceal all online activity. DNS lookups, which translate human-friendly domain names like `example.com` into numeric IP addresses, can still reveal the specific sites being visited.
* **IP Address Geolocation**: While IP addresses are used to route data across networks and MAC addresses identify devices on a local segment, an IP address does not pinpoint an individual's exact physical location. Instead, it generally identifies a network or region, and multiple devices often share a single public IP address through Network Address Translation (NAT).

Privacy, Addressing, and Network Visibility

A frequent misconception is that the cloud is an abstract concept operating without physical hardware.

In reality, the cloud consists of concrete, physical infrastructure: data centers—essentially other people's computers—accessed over the network to power web, email, streaming, and cloud applications.
