Answer 1

Earliest Deadline First (EDF) is optimal for both preemptive and non-preemptive cases in managing independent tasks with computation times and deadlines. It ensures the efficient use of system resources.

Earliest Deadline First (EDF) is an optimal scheduling algorithm for managing a set of n independent tasks, arriving at t=0, with computation time Ci and deadline Di. It works by prioritizing tasks based on their deadlines, serving the task with the earliest deadline first.

In the preemptive case, EDF allows preemption, meaning that a task can be interrupted to make room for a higher priority task. When a new task arrives, EDF checks if it has an earlier deadline than the current task. If so, it preempts the current task, ensuring that tasks with the earliest deadlines are always served first. This method guarantees optimal scheduling since no deadlines are missed if a feasible schedule exists.

In the non-preemptive case, EDF does not allow tasks to be interrupted once they have started. Despite this limitation, EDF remains optimal for independent tasks. Tasks are sorted by their deadlines, and the scheduler picks the earliest deadline task without interrupting any ongoing tasks. As tasks are independent, their execution order does not affect each other's deadlines. This ensures that tasks are executed as close as possible to their deadlines, minimizing the chances of missing any deadlines.

Thus, EDF is optimal for both preemptive and non-preemptive cases in managing independent tasks with computation times and deadlines. It ensures the efficient use of system resources while minimizing the likelihood of missing task deadlines.

Eyepiece, stage, diaphragm and  revolving nosepiece are some of the important part of the microscope with different functions. such as Eyepiece carry the Ocular lens that helps to look the specimen, stage allows light to pass through, diaphragm regulates the amount of light reaches the eyepiece, and revolving nosepiece are use to change magnification.

So, Diaphragm controls the light that passes up toward the eyepiece and help in viewing the specimen. Diaphragm is located below the stage and above the condenser.

Hence, the correct answer is "C. diaphragm".

Explanation:

An integrated development environment (IDE) is a software suite that consolidates basic tools required to write and test software.

Developers use numerous tools throughout software code creation, building and testing. Development tools often include text editors, code libraries, compilers and test platforms. Without an IDE, a developer must select, deploy, integrate and manage all of these tools separately. An IDE brings many of those development-related tools together as a single framework, application or service. The integrated toolset is designed to simplify software development and can identify and minimize coding mistakes and typos.

Some IDEs are open source, while others are commercial offerings. An IDE can be a standalone application or it can be part of a larger package.

Answer:

1. Modularity.

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.

Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard. Some of the models or techniques used in the design of a software are;

Modularity: refers to the concept that software architecture has the ability to divide into modules and that eachmodule can be examined independently. Refinement: is a process that elaborates on each design component until it reaches the coding details.Structural partitioning: allows designers to split a program structure horizontally and vertically.Data Structure: represents logical relationships between individual data elements.

Basically, the views that are available on the Microsoft PowerPoint application includes;

1. Slide Sorter.

2. Notes Page.

3. Reading Pane.

4. Presenter view.

Presenter view avails the user an ability to use two monitors to display his or her presentation. Thus, one of the monitors displays the notes-free presentation to your audience while the other monitor lets you view the presentation with notes that you have added to the slides, as well as the navigation and presentation tools.

In this scenario, Shawn has connected his laptop to a projector and chosen to duplicate his screen to the projector. Hence, the statement which is true in this situation regarding the Presenter view is that it will not be used by default but can be selected by the user.
