VLANs (Virtual Local Area Networks) provide multiple benefits, including segmenting the broadcast domain, which reduces unnecessary traffic and improves network performance. They also enable the logical grouping of devices across different physical Layer 2 switches, enhancing network management and security by isolating traffic between different VLANs.

Organizing code into modules helps manage large and complex systems by breaking them down into smaller, more manageable pieces. Each module can be developed, tested, and maintained independently, which simplifies the overall development and maintenance process.

Jitter refers to the variation in packet arrival times, which can cause packets to arrive out of order, leading to choppy audio or dropped parts of a conversation in real-time VoIP applications. Latency and delay refer to the time it takes for a packet to travel from source to destination, and capacity refers to the bandwidth available, but jitter specifically affects the consistency of packet delivery timing, which is critical for VoIP quality.

The sequence diagram shows the process where the API client first calls the /organizations endpoint to get the list of organization IDs. Then, for each organization, it makes a call to the /organizations/(orgId)/networks endpoint to retrieve the networks for that organization. Since there are two organizations, the GetAllNetworks function will make two parallel calls to the /organizations/(orgId)/networks endpoint, one for each organization.
