Answer:
Output device.
Explanation:
An output device can be defined as a hardware device that typically receives processed data from the central processing unit (CPU) and converts these data into information that can be used by the end user of a computer system.
All of the output device of a computer are known as peripheral devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since output devices are peripheral devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of output devices are monitor, speakers, printer, projector etc.
Hence, when you hear music, read a printout, or view a video, you are using a computer's output device.

D) use SQL or graphical tools to query the database
Explanation:
To query the database using SQL or graphical tools will help Howie to retrieve bulk of records from the database according to his requirements and it will help to understand and work with the data in a better way than using the data in raw form.
SQL is a language of database used to manipulate and manage the data in the relational database and to query the database.
It is an easy and faster way to query using SQL or graphical tools because no coding is required here.

c. recovery time objective
Explanation:
- Recovery time objective (RTO) is the maximum acceptable duration permitted between an unfortunate loss or failure and the restoration of normal operations and services.
- According to the RTO, the systems, applications or operations must be restored within a targeted time period after a disaster, to avoid unacceptable outcomes of the disruption.
-
So a business process must be recovered within this period of time.

- For instance a 2-hour RTO refers to restore and get operations or services back to running within 2 hours of the service failure or outrage.
