Next Lesson
Summary
The content provides a detailed walkthrough on solving a global question related to identifying the initial computer infected in a virus chain, utilizing logical reasoning and process of elimination based on a set of given rules.
- Rule number 3 indicates that R and S cannot be the initial computers infected as they must receive the virus from another source within the network.
- Rules 4 and 5 further eliminate Q and P as potential starting points since their infections are contingent upon receiving the virus from specific computers.
- Through process of elimination, T is identified as the only computer that could feasibly be the origin of the virus chain.
- A hypothetical scenario is constructed to demonstrate how T infecting other computers adheres to all the given rules, confirming its position as the start of the virus chain.
