Real_time_and_Multimedia_3 PTS Your friend is a geologist who studies earthquakes and tsunamis. They have placed 1000 seismograph sensors all around the world. Each sensor produces a 1 kilobyte datapoint every second. They have also placed 50 cameras in coastal areas around the world that record at 60 frames per second. Each video frame is 1 MB.  Your friend wants to record this data and analyze it for two purposes:  To send urgent alerts when multiple sensors in a region report strong shaking in the same brief time window. To correlate timestamped video recordings with timestamped seismograph data in order to study what types of shaking cause tsunamis. Is PTS a good basis to build a system for analyzing this data? Justify your answer. 

Failures_and_Recovery_6c Quicksilver The context for this question is same as previous. You are designing a distributed database system on top of the Quicksilver operating system. The system allows clients to perform “read” and “write” operations on data stored across multiple nodes. Each operation generates a transaction tree for recovery purposes.
