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.
Testing ensures that all hardware and software components work together
Answer: C. Differential backup
Explanation: There are several ways od ensuring the preservation and storage of data even cases of disaster, one of such ways is data data mirroring which allows data to be replicated or copied in real time and several backup options. In cases where there there is need to restore a server, the warm recovery site provides a data or disaster recovery option used to mitigate the effect of data loss on organization. In the absence of data mirroring, differential backup option, provides the quickest recovery option as it only requires changes in the data stored after the last full backup. These speed experieced should be expected due to the relatively low data been dealt with rather than the entire data.
The kind of material that is used for DRAM (dynamic random-access memory) is metal-oxide-semiconductor.
<h3>What is DRAM?</h3>
DRAM was invented in 1968. It is a type of RAM used in modern computers and laptops. It is a type of random access memory. Its name is dynamic random access memory.
Metal-oxide-semiconductor is used in making the transistors and capacitors of the DRAM, which are used to store the data. They hold a bit of the data in these capacitors and transistors.
Thus, the material that is used is metal-oxide-semiconductor to make DRAM (dynamic random-access memory).
