A multilayer switch maybe?? I hope it’s right
"To preform specific useful computing tasks, like word processing and calculation" is the correct answer. This is the whole purpose of system software. The third answer is some other type of software(third party software?) and the fourth answer is most likely a compiler. Those are the easiest to take off. The second could also work.
The two answers I would go with are the first and the second.
Answer:
1. A browser is used to access websites and web pages whereas a search engine is used to search for particular information.
2. Indexing is the process by which search engines organise information before a search to enable super-fast responses to queries.
3.Search engines are used to find specialized data rapidly whereas web directory is used to find a list of different sites.
4. The working behind the PageRank algorithm is that a page with a large number of in- links(a link from an important page) to it, then its outgoing links to other pages also become important. It gives more importance to back links of a web page and propagates the ranking through links.
5. Look for Sites from Established Institutions 2. Look for Sites with Expertise 3. Steer Clear of Commercial Sites 4. Beware of Bias 5. Check the Date 6. Consider the Site's Look 7. Avoid Anonymous Authors 8. Check the Links
Explanation:
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.
