Answer:
c. User applications usually communicate directly with a device driver.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem. Thus, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.
The four (4) input-output (I/O) software layers includes the following;
I. Interrupt drivers (handlers): it is responsible for handling interruptions that occur while using a software on a computer system.
II. Device drivers: it controls the input-output (I/O) devices that are connected to a computer system through a wired or wireless connection.
III. Device-independent OS software: it allows for uniform interfacing and buffering for device drivers.
IV. User level software: it provides user programs with a simple user interface to perform input and output functions.
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Hence, user (software) applications make a request to the operating system (OS) to use a device and then the operating system (OS) communicates with the device driver.
In conclusion, user applications do not communicate directly with a device driver.

a. First Person
b. Second Person
c. Third Person
Answer:
The point of view in this paragraph is:
a. First person.
Explanation:
The narrator of the excerpt is telling the story from a first-person point of view. The easiest way to confirm that is by taking a look at the pronouns used:
The dew on the grass made my running shoes damp. It didn't bother me. The sound of my feet hitting the street formed a rhythm, a steady pattern of light thumps. I timed my
breathing with the rhythm.
<u>First-person narrators use first-person pronouns such as "I" and "me". This type of narrator gives us his/her own perspective on things. That means we accompany this narrator throughout the story, see things from his perspective, and only get to know what he knows. One advantage of first-person point of view is that we get to dive deeper into the narrator's feelings and thoughts. One disadvantage is that he is a biased narrator, which makes him untrustworthy.</u>

A helping verb helps a main verb describe an action. This action can be an event that happened in the past, present, or will in the future. Other helping verbs are should, could, and will. Have is a helping verb because it help the main verb in a sentence to complete out a task whenever that may be.
Ex.

This sentence shows that James will carry out an action by helping Mary with her homework, by using the word, "have".
