Answer:
<em>Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.</em>

Answer:
The code for the function is given below in Python language
Explanation:
def append_string_to_file(filename, text):// function takes the filename // and text to append
f = open(filename, 'a')
f.write(text) //function part that writes the text
f.close() //closing the file using the explicit close function
Answer:
The answer is "Fiber Optic Cable".
Explanation:
In the given question options are defined, but in these options, there is some error.
The optical fiber cable is also known as internet wiring, which includes fiber strands inside an isolated housing. It is used to transferring data at a very high speed. This cable is developed for long-range data networking, high-performance connectivity, and multimedia, and other choices are wrong that can be described as follows:
- A modem is used to transmits data over a network, that's why it is wrong.
- Router is used to transport traffic between your computer and the internet, that's why it is wrong.
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.
It’s Debug. definition: “identify and remove errors from (computer hardware or software)”.
