| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Internet Protocols (TCP/IP, ARPANET) (internet_protocols_tcp_ip_arpanet) | enabling | 68% | expert_inference | Internet Protocols (TCP/IP, ARPANET) provides a capability that enables this technology without being the only possible path. |
|
| Virtualization (Early VM Tech) (virtualization_early_vm_tech) | historical_predecessor | 75% | expert_inference | Virtualization (Early VM Tech) is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
|
| Software Engineering (software_engineering) | enabling | 68% | expert_inference | Software Engineering provides a capability that enables this technology without being the only possible path. |
