Information Technology Question

 

  1. In a 2-3 page APA-formatted paper, research and describe 3 approaches to detecting errors within a network, including how the approaches work, the probability of detecting an error, and any other benefits or limitations. If you have used any network monitoring tools before, describe your experience and any challenges you may have experienced.
  2. Please choose one of the following two options and write your work in a 3-4 page APA-formatted paper. You are welcome to include diagrams within your work as appropriate, and if they are brought in from outside sources, be sure to provide proper citations and references. Do not go overboard with your designs, but consider each option carefully and provide an overview of the recommendations.

 

Option 1

You have been hired by a small company to install a backbone to connect four 1000base-T Ethernet LANs (each using one 24-port switch) and to provide a connection to the Internet. Develop a simple backbone and determine the total cost (i.e., select the backbone technology and price it, select the cabling and price it, select the devices and price them, and so on). Prices are available at www.datacommwarehouse.com, but use any source that is convenient. For simplicity, assume that category 5e, category 6, and fiber-optic cables have a fixed cost per circuit to buy and install, regardless of distance, $100, $120, and $300, respectively.

 

Option 2

You have been hired by a small company to install network infrastructure with shared storage. The office has 15 users. Business administration has requested that the accounting department, which has one user, not be on the same network as the operation network to protect business financial data traffic and maintain separate access to files and data.

 

Either Option:

In either case, consider the following requirements, but do not write your paper to solve all of these needs. Simply consider the needs in your network design solution:

  • Windows Server and Active Directory requirements
  • DHCP and DNS
  • IP addressing, VLANs, and subnet mask requirements to accommodate the number of users
  • NAS/SAN as appropriate
  • Print Server (if required)

 

Provide diagrams of at least two design options.

Discuss and compare the advantages and disadvantages of each proposed design and justify your recommendations. Consider cost, security, on-going maintenance, adding new users, printing, log-in, and Internet connection to all users.

  1. Although it is important to protect all servers, some servers are more important than others. In a 2-3 page APA-formatted paper, please answer the following questions:
  • Which server(s) are the most important to protect and why?
  • Which criteria would you use to determine which servers to protect first?
  • What are some of the methods you would use to protect the different services?
  • Which requirements may differ between protecting local servers vs. cloud servers?
  1. You have been tasked with setting up a new company branch office for an existing organization. The company headquarters is in a different state but houses the main accounting server and company databases. The new branch office will need high speed Internet access and a VPN connection to the main office. The branch is expected to host 15 to 20 users. Due to the secure nature of the accounting and database systems that must be connected, you also must develop a plan to incorporate network security to meet their needs. Research and design a solution to address these requirements. While cost is always a factor to some degree, it would be best to recommend two options, good and optimal. Write your plan in a minimum 4–5-page APA-formatted paper, including network maps and pricing charts as appropriate. You will deliver your proposed solution in the Week 8 live class session.

 

 

Provide an in-depth analysis of securing and maintaining a network server operating system in a 5-6 page APA-formatted paper. List and compare these differences in order to determine which would be the best option for your place of business.

Information Technology Question

  1. In today’s world of constant change in technology, we must ensure that we are always up to date with the latest operating systems. Research and determine the best solution for a medium-sized business with 500 employees. This is a new company, and you need to determine if Windows, Linux, or another type of operating system would best benefit this network. These users require constant sharing of resources and authentication throughout the network on a regular basis. Your paper needs to address the following:
  • Benefits of the operating system
  • How this operating system compares to other operating systems
  • Security concerns with this operating system
  • Flexibility and scalability with this operating system
  • Cost and maintenance of this operating system

 

  1. Virtualization has become quite beneficial for not only organizations but network administrators as well who rely on this technology on a constant basis. For this week’s assignment, you will research why virtualization is so important and how it has been so beneficial to network administrators over the past few decades. Be sure to research server virtualization for large networks. Also, try to find current literature that supports your justification on why virtualization is so important and useful today. Submit your findings in a 2–3-page APA-formatted paper.
  2. The fundamentals of network communication today have not completely changed over the past 50 to 60 years. In fact, many of the same theories and concepts are still the same. Research and list 4 of the common network topologies that have been used in businesses over the past few decades. You will indicate which of these typologies are still in use today, and why they are still in use today. You will also indicate what types of resources and devices are commonly used within these topologies. For instance, in a star topology, is a router or a switch required? Additionally, list how a current operating system needs to be properly configured in order to support all of these devices across the topology. Submit your work in a 2–3-page APA-formatted paper.
  3. Provide an in-depth analysis of securing and maintaining a network server operating system in a 5-6 page APA-formatted paper. Microsoft Windows Server 2022 is the latest server produced by Microsoft that brings in many new technologies, such as Azure integration and advanced multilayer security enhancements. List the benefits provided by this new Windows server OS and compare them to other servers currently on the market, such as Linux and Apache. List and compare these differences in order to determine which would be the best option for your place of business. Justify your reasoning. Be sure to include all the elements that would be required in order to better secure and safeguard the operating system.

Justify why this was an appropriate decision and what could happen if an employee consistently makes errors. Write about your comfort level and experiences in writing in a formal style.

/in /by

Unit 1 Discussion

This unit’s reading includes a list of reasons why writing matters as well as information about formal writing. After reading this, take some time to contemplate the importance of these concepts in securing a job.

Your initial post must include the following:

  • In your first paragraph, consider that you are an employer seeking to hire someone. There are only two applicants whose IT skills and credentials seem equal, but one provided a large project document (in a portfolio) with many grammar errors and an informal style that seems inappropriate. You have decided to hire the person whose application materials were all well written. Justify why this was an appropriate decision and what could happen if an employee consistently makes errors.
  • In your second paragraph, write about your comfort level and experiences in writing in a formal style.
  • Do not use source material for this discussion; use your critical thinking skills.

In responses to others, it would be appropriate to share experiences with writing resumes, cover letters, and/or portfolio documents, either from the applicant or the employer’s viewpoint, or explain other instances in your career so far that required formal writing.

Discussion parameters:

  • Write your initial post in your own words; do not quote or copy from sources.
  • Do not copy the questions into your post.
  • Write an original descriptive subject line for your initial post (do not include the unit number or your name).
  • Write with formal, professional language, as explained in the reading.
  • Work to meet all posting guidelines and expectations.

CS1410 Object oriented programing

Create a base which could be augmented and built on in the future. Whether it be for assignments to come, classes to come (for example AI), or even just for fun (if you think genetic algorithms are fun).

Essentially, what you will be building here is a world with creature objects in it. This creature object will need to be built in such a way that one day it could move, sense, eat, starve, etc. But to begin with it just needs to be created, die, and reproduce based on preset odds.’

So in terms of proper requirements this assignment must include, in both the UML diagram and code, the following:

  1. At least three classes and/or interfaces (3 total not 3 of each).
  2. At least two relationships.

As For a potential prompt you could read these requirements in these terms:

  1. A creature class with space for creature attributes and methods (eg. chances of replicating and dying). Required creature specific methods:
    1. die()
    2. reproduce()
  2. A world class with world and environment attributes and methods (eg. chances of spawning new creature without replication). Required World specific methods:
    1. createCreature()
    2. This method might hit the names.txt file in this project to get a random name for your creatures.
    3. spawnFood(), etc.
  3. Support for multiple creatures within the world.
  4. Main loop where these chances are ‘rolled’ for a number of times in a row.

You may, however, build any sort of system you wish as long as it has 3 classes and/or interfaces and 2 relationships. Use LucidChart

Links to an external site., draw.io

Links to an external site., or any other preferred diagramming tool to create your UML diagram.

This assignment will be submitted in two pieces, you will need to create a UML diagram showing how you plan to implement a coded solution to this prompt as well as the actual code. The UML diagram will have a separate due date and submission dropbox within canvas while the code will be submitted here in GitHub .

Find the customer with the most rented movies- What is the employee job description with the most employees

/in /by

Database management systems final project of about rental cars

Before Netflix existed, there were stores where you rented a movie in either a video cassette (VHS) format or a compact disc format (DVD). But then, in 1997, Netflix was founded by Reed Hastings and Marc Randolph as a DVD-by-mail rental service. The company initially offered a subscription service where users could rent DVDs and receive them by mail. Netflix distinguished itself from traditional video rental stores by eliminating the need for customers to leave their homes to rent movies.
Imagine you are back in the nineties and the early 2000s; imagine that VideoFlick is a video rental store that rents out movies in VHS tapes format. You are given a dataset of video rental records kept by several employees. After each employee rents out a movie/movie to a customer, they enter the transaction information into an Excel sheet. Even though VideoFlick is a one- branch store, they are trying to expand by opening more stores. The company’s leadership
realized that keeping records using an Excel sheet is not an efficient way of storing information. So, they decided to hire programmers to design and build an information system that would help employees enter the information for each transaction quickly and help in business decision-making by applying data mining algorithms to the database. The
programmers decided first to build a relational SQL database that would allow the creation of a graphical user interface and a data analysis application.
The programming team was given the Excel sheet attached to this document as an example of how employees used to keep records. Each movie has a number as a unique identifier. Also, each movie has multiple copies with copy numbers. The combination of movie number and copy number creates a unique identifier for each VHS tape in the store. Each customer might rent multiple movies, and they would all be counted as one transaction. The rental fee for each movie rented is per day. If the return date is the same as the rental date, this is considered one day. If it is the next day, this is regarded as two days. The customer must pay the fee when they

2 Dr. Islam Ebeid MCIS 5133 Database Management Systems Final Project return the movie or movies they rented. The transaction is closed only after the customer has returned the movie. If the movie were returned late, an additional fee would be applied. Each transaction has a unique identifier. Also, each transaction stores employee information, customer information, and rented movies information.

Your task
As one of the programming team, you are tasked with:
1- Studying the dataset and exploring it.
2- Designing a relational data model that would replace the Excel sheet that the employees
used before to record information.
3- Implementing the ER model you created using the MySQL database management
system and MySQL Workbench.
4- Answering the queries provided below using SQL select and join statements.

What to submit
1- A Conceptual Level model: An ER diagram describing your entities, relationships, cardinalities, and attributes.
2- A Logical Level model: A Class diagram describing your entities as classes with attributes and methods and the relationships between them, including inheritance. For example, your database might have 2 separate tables: employee and customer. Yet, in your class diagram, you might have a third class called a person from which both
customer and employee inherit, even though there might not be a table person in your database. The class diagram will be used to build other applications on top of the database in the future.

3- A Physical Level model: A Database ER Schema diagram generated using MySQL Workbench after you create your tables describing the tables, attributes, relationships, and cardinality that corresponds to your ER diagram. This diagram should include primary and foreign keys, data types, data sizes, and resolved many-to-many relationships.
4- A separate description of each table and its attributes and relationships in the ER and
the Database Schema diagrams

3 Dr. Islam Ebeid MCIS 5133 Database Management Systems Final Project
5- A separate description for each class and its relationships in your Class diagram
6- The DDL Create tables statements as a separate .sql file
7- Insert the data provided in the Excel sheet into your newly created database, then give
the insert statements as a separate .sql file
8- Your SQL answers to each of the queries below
9- The results of your SQL queries as images, as some of you have done in the previous
assignment.

Important notes
1- The ER diagram should be at least in the 3rd Normal Form
2- Use Chen notation for the ER diagram
3-Use UML notation for the Class diagram
4- Use UML notation for the Database ER Schema diagram describing your tables
5- You can insert the data in the Excel sheet using import in MySQL Workbench, but you
will have to preprocess the data a bit.

Queries
1- Find all the movies with the word “earth” in their titles.
2- Find all transactions that happened on April 18th, 2011
3- Find all transactions that happened after April 18th, 2011
4- Find how many transactions each movie has in the database.
5- For each customer, find out how much they spent.
6- Find how many transactions each employee has in the database.
7- Find the customer with the most rented movies.
8- What is the employee job description with the most employees?
9- Who is the newest employee?
10- What is the most profitable movie/movies in the store?
