  TECH TOPIC CONNECTION: NETWORK SECURITY In this final blog post cataloging my efforts through my TEC101 course, we'll delve into the crucial realm of network security and explore its intricate connection to the fundamental aspects of information technology covered throughout this course. Network security is an indispensable component of the IT landscape, as it safeguards data, systems, and communications from unauthorized access and malicious threats. To comprehend its significance, let's dissect its relationship with key IT concepts, hardware components, programming languages, application software, database management, and network architecture, management, and security. Network Security and Information Technology Concepts At its core, network security aligns with the foundational concepts of information technology. It revolves around the protection of data and systems, ensuring the confidentiality, integrity, and availability of information. This resonates with the fundament

THE CRITICAL IMPORTANCE OF INFORMATION AND SYSTEM SECURITY In the digital era, the security of information and systems has become a paramount concern for individuals and organizations alike. As the world becomes increasingly interconnected through computer networks and information systems, it is vital to adopt a proactive stance in safeguarding data integrity, confidentiality, and system reliability. This blog post underscores the profound significance of information and system security and delves deeper into pivotal computer security incidents: vulnerabilities and computer viruses. Ping Commands and Potential Threats: Ping Flood Attack: The ping flood attack is characterized by the inundation of a target system with an excessive volume of ping requests. These requests, often initiated from a botnet, overwhelm the target's network infrastructure, and consume its available bandwidth. The consequences are manifest in network disruptions or significant slowdowns, thereby rendering ser

COMPUTERS IN THE WORKPLACE   The Role of Computers in Healthcare: Current and Future Impact In the healthcare industry, computers play a vital role in transforming patient care, administrative processes, research, and overall operational efficiency. The integration of information technology has led to enhanced medical diagnoses, improved patient outcomes, streamlined workflows, and the collection of vast amounts of data for research and analysis. Patient care devices, ranging from wearable health trackers to advanced diagnostic equipment, have further revolutionized healthcare delivery. Current Functions of Computers in Healthcare: Electronic Health Records (EHRs):  Computers facilitate the creation, storage, and accessibility of patient health records, ensuring accurate and efficient management of patient data. Medical Imaging and Diagnostics:  Sophisticated imaging equipment, such as MRI and CT scanners, rely on powerful computing systems for image processing and interpretation. Tele

TRAVELING THROUGH A NETWORK Using Ping and Traceroute to Explore Network Paths In the world of networking, understanding how packets of information travel through networks is essential for diagnosing and troubleshooting issues. Ping and traceroute commands are valuable tools that provide insights into the paths that data takes as it navigates the internet. In this activity, I used these commands to explore the journey of data packets and gain a better understanding of network connectivity. Ping Activity: I started by using the ping command to test the connectivity to Google.com. The results showed that a certain number of packets were sent, received, and lost. The response speeds varied, showcasing a range of milliseconds. This initial ping test demonstrated the roundtrip time between my computer and Google's servers. I then extended the ping test to two other websites hosted in different regions of the world. The results highlighted differences in response times due to the geograp

  DOCUMENTING A DAY   The Role of Applications in Productivity and Efficiency In today's fast-paced digital landscape, software applications have become indispensable tools that greatly enhance productivity and efficiency across a wide range of tasks. These applications, including word processors, spreadsheets, presentation software, and database tools, serve distinct purposes, each with its own set of advantages and disadvantages. In this comprehensive discussion, we will explore the functionalities, pros, and cons of these applications. Additionally, we will recommend a suitable application for documenting daily activities and explore various scenarios where each type of application proves invaluable. Word Processors: Word processors are versatile tools for creating and formatting textual content. They empower users to compose, edit, and format documents seamlessly, offering several advantages, such as flexible formatting options, real-time collaboration, and robust editing capab

PROGRAMMING LANGUAGES: EXPLORING THE LOGIC OF COMPUTATIONAL THINKING WITH SCRATCH AND PYTHON Exploring the Logic of Computational Thinking with  Scratch and Python In this reflection blog, I will discuss my experience building a program using Scratch, a drag-and-drop block programming language, and explore the insights gained about programming. Additionally, I will compare my Scratch programming experience with the participation activities in the  textbook that  cover machine language, assembly language, and high-level languages like Python. My goal was to understand how the different levels of programming languages each have their own advantages and disadvantages. Through my experience, I was able to see that Scratch provided an interesting and intuitive way to learn the basics of programming, while the textbook activities allowed for a deeper dive into the complexities of programming. 1.        Experience with Scratch:  Building a program using Scratch was an enjoyable and enlighteni

My name is Melissa and I am from Alabama. I have 3 kids and 3 dogs.  I work as an IT Service Desk Trainer. I have been with this bank for over 5 years now. This is my 4th role within the company. I started out in IT Tier 2, moved my way to branch tech, then a quality analyst role, and now the Trainer role. When I was in Tier 2 at my current company, I was remoting into computers or working on them in person at the branches to get them up and running properly. I also helped with networking with the switches and such as well. I think I am a Senior at UAGC since I will finish all my classes in Sept of next year. If not, I am very close to becoming a senior. I am working on my Bachelor's in IT. I hope this helps me to be able to either move up in the company to make more money or when my son graduates high school, I will try and find a better-paying job somewhere else. I do like it at the bank with my current role because it taps into the training knowledge from a previous company, and
