Answer:
<u>class -files and auxiliary resources</u>
Explanation:
JAR stands for Java Archive which allows one to make multiple file bundles into a single file which is archive file and these JAR files contains in them the the auxiliary resources and the class files.
The archive file allows us to be storage efficient by compressing our data and files.
These files also allows us to transform our software into extensions as well.
For the enforcement of consistency of version of the packages, these files can be sealed optionally.
Answer:
<em>DBMS Performance
</em>
Explanation:
Database tuning <em>defines a range of activities that are used to maximize and homogenize a database's output.</em>
This typically coincides with query tuning, but applies to database file layout, DBMS software selection, and database environment setup (operating system, CPU).
Database tuning helps to optimize the use of machine resources in order to carry out work as efficiently and quickly as possible.
Many systems are built to handle their use of system resources, but there is still plenty of space for enhancing their performance by tailoring their server and DBMS settings and configuration.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Most business applications and websites use and process the credit card for their transaction.
For example, e-commerce website such as ali baba, am a zon, accepting credit card transaction when the customer gets to purchase any product from their stores.
