C. answer the least challenging questions first
because then you get those out of the way and have more time to focus on the harder questions.
Answer:
Interrupts.
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.
The four (4) input-output (I/O) software layers includes the following;
I. User level software: it provides user programs with a simple user interface to perform input and output functions.
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. Interrupt drivers (handlers): it is responsible for handling interruptions that occur while using a software on a computer system.
An interrupt is a signal from a program or device connected to a computer and it's typically designed to instruct the operating system (OS) that an event has occurred and requires an attention such as stopping its current activities or processes.
In conclusion, the computer term that Selma is describing is interrupts.
Answer:
a. Radom Access Memory (RAM).
Explanation:
If a computer user modifies a document that is saved on his or her computer. This changes are stored on the Radom Access Memory (RAM) until the computer user save the document.
Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
Answer:
Classification
Explanation:
Building a machine learning solution that can predict the success of a student in completing a college degree is a binary problem. There are two possible answer: success or not success.
This brings us to a supervised machine learning problem, where one trains the technique with labeled data whether it is a success or not. Since the target variable is discrete (not continuous), classification technique has to be used.
