Design Choices and Transactions in Distributed Systems Quiz

Design choices of DSes = Almost always involve a compromise Distributed transactions = Often necessary but harder to design because of shared resources Hardware support for implementing a semaphore = Not available for distributed systems that don't share memory Interprocess communication using shared memory = Not used in DSes, instead messages are sent to coordinate among processes

Rollback = A transaction is cancelled and all changes made by it are undone Commit = A transaction is completed and all changes made by it are made permanent Checkpoint = A point in a transaction where all changes made so far are recorded UUID = Universally unique identifier

A DS expert will be educated about what the best compromise will be = Design choices of DSes A process may be required to manage shared resources in a critical section = Distributed transactions Test and set instruction is used for implementing a semaphore = Hardware support for implementing a semaphore Messages are sent to coordinate among processes = Interprocess communication using shared memory

<p>Shared memory = A region of memory that can be accessed by multiple processes IPC = Interprocess communication using actual shared memory set up by the operating system Workable = Fast globally shared memory for distributed processes UUID = A unique identifier used in distributed systems</p> Signup and view all the answers

<p>Design choices of DSes = Associated with a compromise and requires expertise Distributed transactions = Complex to design due to the need to manage shared resources Hardware support for implementing a semaphore = Not available for distributed systems without shared memory Interprocess communication using shared memory = Not used in DSes, instead messages are sent</p> Signup and view all the answers
