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.
Answer:
True.
Explanation:
When you established social links, your social media site profile may eliminate almost any generic symbol throughout the list of contacts and the Individuals Pane with profile pic the contact may have placed. Thus, the Users Pane would be exchanged with profile image of the contact while establishing the social connections.

<u>Virus outbreaks in an organization:</u>
In an organization end user who uses the computer or laptop or workstation is not aware of virus outbreaks. So As IT administrator of an organization she/he has aware of latest virus attack and rectification solution before outbreaks.
Common causes for this virus outbreaks problem is update virus definition or database. Update operating system patches on regular basis.
Installation appropriate anti-virus in each workstation or desktop or laptop and scheduling virus scanning and take necessary steps.
To address and troubleshoot disconnect workstation and desktop or laptop from LAN. Uninstalled unnecessary software, delete temp folder contents.
