Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.
Yes it only processes data using 1s and 0s
Answer:
B) Release candidate
Explanation:
The release candidate is the last stage or final stage of software testing by vendors before it can be officially released to be sold commercially. The release candidate is usually carried out by a very large community of customers.
Some vendors may have to bring out just more than one release candidate if problems are discovered in the first RC.
Release candidate generally feature complete and supposedly bug free, and ready for use by the community.

Answer:
Yes! You can try to Force start it or connect it to a computer that can diagnos your problem.
Explanation:
Assuming you have a iphone Press the Off button and the down volume key for 20 seconds that should start the phone, Bring the phone up to your ear and try to hear if anything is happeneing. If that is a fail you can shoot me a email and ill send you a few apps that you can diagnoss your phone with.
