Answer:

Secure firewall , Access Control Lists (ACLs) , and Bastion hosts

Explanation:

In this scenario, the best options to be able to accomplish this would be a Secure firewall , Access Control Lists (ACLs) , and Bastion hosts. A secure firewall and an access control list will prevent specific harmful files and computers from entering a network unless it has the proper clearance. A bastion host on the other hand is a special-purpose computer on a network specifically designed and configured to withstand attacks, acting as a secondary defense mechanism.

gavmur [86]

Answer:

The correct answer will be "Semi-structured data".

Explanation:

  • Semi-structured data comprise evidence that just isn't data collected in some kind of a traditional database management system, but then neither is content typed.
  • It's indeed descriptive information or structured data, but that's not organized into a theoretical design, like a chart or perhaps a graph centered through an entity.

So that the given scenario is the example of semi-structured data.

Explain an application of a data communication system, including issues encountered with implementing the application.
aleksandrvk [35]

Answer:

Data communication system is referred to the exchange of information between the sender and receiver by use of transmission media.

Explanation:

The data communication system is referred to as the exchange of information between the sender and receiver by the use of transmission media.

some application of data communication system are;

videoconferencing,  

instant messaging

Telnet, etc.

In the data communication system, one information is transferred is transmission circuit then the media transfer the information to the receiver into the desired format.

the main issue is:

- data privacy

- cost of implementation

- use of the system for personal used during working hour

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.
