Which is among the earliest formats of audio used in video games? A. MP3 B. wave table synthesis C. pulse code modulation D. MOD

solong [7]

Answer:

MOD

Explanation:

MOD audio file format is primarily used to represent music. It uses the .MOD file extension and has had popularity as background music for independent video games. It would be safe to say that MOD audio file extensions are the most widespread trackers that were used and are still being used in many computer games and demos.

Modern operating system decouple a process address space from the machine's physical memory. list two advantages of this design.

likoan [24]

The two advantages of modern operating systems is that it has the capacity in helping programs to be loaded faster compared to other older versions and it also has the ability of having to run programs that are large enough in which is in the main memory even if it is smaller compared to the size of its program.

Compare the elements of the basic Software Development Life Cycle with 2 other models. How are they similar? How are they differ

Artemon [7]

Answer:

Explanation:

One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:

1. Waterfall model

2. Iterative model

3. Spiral model

4. V-shaped model

5. Agile model

Stage 1. Planning and requirement analysis

Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.

Stage 2. Designing project architecture

At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.

Stage 3. Development and programming

After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages

• Algorithm development

• Source code writing

• Compilation

• Testing and debugging

Stage 4. Testing

The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.

Stage 5. Deployment

When the program is finalized and has no critical issues – it is time to launch it for the end users.

SDLC MODELS

Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.

ADVANTAGES

Simple to use and understand

DISADVANTAGES

The software is ready only after the last stage is over

ADVANTAGES

Management simplicity thanks to its rigidity: every phase has a defined result and process review

DISADVANTAGES

High risks and uncertainty

Iterative SDLC Model

The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.

ADVANTAGES

Some functions can be quickly be developed at the beginning of the development lifecycle

DISADVANTAGES

Iterative model requires more resources than the waterfall model

The paralleled development can be applied Constant management is required

Spiral SDLC Model

Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.

Megan has written the following rough draft for her assignment. Choose the correct way to complete each sentence. Sarah is creat

atroni [7]

Answer:

I. hatching

II. filter

Explanation:

Sarah is creating an image. She wants to achieve tonal effects with parallel lines by varying their densities and distribution patterns. She will use hatching to do this. She also wants to add special effects on the image. Therefore, she will use filters.

Hatching refers to an art technique in which parallel lines are used to shade by drawing them closely together.

Stippling is an art technique used in the making of patterns by using small dots.

Filters is a technique of changing image characteristics. It is used to change the picture characteristics & to add special effects to an image such as the shade, contrast, tone, brightness etc.

We therefore see that, hatching and filter are the correct answers respectively
