Microsoft Research Silicon Valley. … Explained through Baseball. Data Replication in the Cloud. Question. : What consistency choices should cloud storage systems offer applications?. Some Popular Systems. Chapter 8: Solutions. When substances dissolve to form solutions, the properties of the mixture change.. 8.1: A solution is a type of mixture. 8.2: The amount of solute that dissolves can vary. 8.3: Solutions can be acidic, basic, or neutral. Lectures 4 and 5. State . Condition of the system as described by its properties.. Usually only a subset of properties need to be specified to identify the state of a system..
