Answer 1

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.

Stealing the Day
by Samantha G. (excerpt)

I achieved the unofficial "smart kid" designation in elementary school, and it was not until years later that I met someone who threatened to depose me from my reign.

His name was George, after our nation's first president, and he had been the smartest kid in school during his early academic career as well; but George grew up on the other side of town, so we had really never crossed paths. We were introduced in our biology class, seated at opposite ends of the first row of desks. When our teacher began asking basic questions to test our science knowledge, George and I had not even noticed each other's existence.

But when Mr. Hartley inquired about the aardvark's natural habitat, both of us shot a hand into the air.

"Africa!" exploded the dual shout, followed by snickering from the rest of the class. I peeked in the direction of the other voice to see George gazing directly ahead, as though he was oblivious to anyone else. Surely, he perceived the awkwardness of this circumstance, and had the abrupt comprehension that there was another "smart kid" in the school! But no acknowledgment crossed his face, and I stared back at my own desk as class continued.

When the bell rang and students began jostling out the door, I hung back, thinking that I should at least introduce myself to George. He had waited for everyone else to push out of the classroom as well, and I extended my hand toward him with a smile.

"I just wanted to let you know that I plan to outdo you in every class we have together this semester, and every semester until graduation," he said.

Without glancing in my direction, George dashed out the door and down the hall toward his locker. I was left in shock at his words, at the audacity of his confidence and conceit. After standing immobile for a few moments, I ducked out the side door of the classroom into the late summer sunshine to comprehend what had just transpired. Ultimately, I came to the apparent explanation to his immature attack: George perceived me as a threat.

When the regional science fair was announced, I knew George had already begun working on his entry, as I had. On the day of presentations, as professors from the local university strolled among poster board displays and homemade volcanoes, I had a clear view of George's project. When he detected my surveillance, George began sauntering toward me and I planted my feet firmly, steeling myself for the verbal assault.

"Is this your first science fair?" he inquired, observing my display critically. "I want to make you aware that I'm going to—"

"I know, I know. You're going to beat me at everything." George smirked, self-satisfied and headed back toward his own project. Anger surged through me as I thought of his haughty conduct, his readiness to belittle me at every opportunity. But it was imperative that George not divert me, and I regained my composure as I spied a science fair judge in my peripheral vision.

By November, George was plainly exhausted by his one-sided antagonism, and I scarcely saw him after Thanksgiving. When report cards were distributed before Christmas, he never approached me to compare grades, and I knew that he had relinquished the battle.

C.
It shows the tension between George and Mr. Hartley that continues throughout the plot.
D.

Answers

Explanation:

c it shows the tension between george and mr. hartley that continues throughout the plot.

The statement which best expresses how the underlined section creates an effect in the plot is option A i.e. It establishes the surprise that the narrator feels throughout the plot.

What is mystery in the excerpt by Samantha ?

A text that causes tension is one that makes the peruser need to figure out more about the subject examined. The sentence that is in all likelihood intended to make anticipation for the peruser.

His name was George, after our countries first president, and he had been the most brilliant youngster in school during his initial scholarly profession also yet George experienced childhood with the opposite side of the town, so we had actually never run into each other.

Given the sentence over, the peruser will be in all likelihood keen on figuring out more about George. Since the storyteller had not exactly run into George, he and the peruser will need to figure out what George is like at this point.

In a story, what causes tension is what is going on that makes the peruser or watcher needing to figure out more about what happened in the story.

Anticipation as a rule keeps the peruser particularly anxious to understand what occurred next in the story line.

Subsequently, the storyteller embarks to let us know that the ways of the two children where yet to cross, so because of that, one will need to realize what happens when their ways cross.

____ of the footballers was
given a cash prize for winning the
championship
(a) All
(b)Any
(d) Most
(C)Some
(e)Each

Answers

Answer:

(e) Each

Explanation:

In English language, each is a word use to describe one of two or more distinct individuals considered separately but having a similar relation and often makes up an aggregate. Thus, each refers to everyone or everything that belongs to a group, regarded and identified separately.

In this context, the footballers are the group of people and each of them were given a cash prize for their victory in the championship.

Hence, the most appropriate word to fill the blank is "each" and the complete sentence would be written as;

"Each of the footballers was given a cash prize for winning the championship."

I want introduction about obesity

Answers

Overweight and obesity are increasing problems that lead to significant health and social difficulties for people. Commonly defined by a measurement of Body Mass Index (BMI - calculated by dividing body weight (kilograms) by height (metres) squared), the prevalence of overweight (adult BMI of between 25 and 29.9) and obesity (BMI of 30 or over) is increasing. For children, these BMI standards require adjustments for age and gender. Overweight and obesity are global problems and the World Health Organization (WHO) predicts that by 2015 approximately 2.3 billion adults worldwide will be overweight and more than 700 million obese. In the UK, obesity rates have nearly doubled in the past 18 years from 13% of men and 16% of women in 1993, to 24% of men and 26% of women in 2011. In the same year, about 3 in 10 children aged 2–15 years were found to be overweight or obese. Ethnic differences exist in the prevalence of obesity and the related risk of ill health. For example, compared with the general population, the prevalence of obesity is lower in men of Bangladeshi and Chinese family origin, whereas it is higher for women of African, Caribbean and Pakistani family origin as reported by the National Obesity Observatory in 2011.
