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.

Option 4. a way for software to communicate and become interactive
is the correct answer.
<h2>
Explanation:</h2>
<h2>The fall of the Berlin Wall and the emergence of a way to find things on the Web through the Netscape browser were two that was browser were two events that flattened the world. A third platform was needed to change the world and that was a way for software to communicate and become interactive.</h2><h2 />
This question belongs to the advent of software and technology that has made world a global village. The factors that played important roles are Fall of Berlin wall and Netscape browser.
The third thing the added to connectivity among people is the production of softwares like Skype and other social applications that made it easier for people to interact with other and communicate faster.
