The goal of this assignment is to become more familiar with and increase your knowledge in Linux OS and Network Tools.
This lab will demonstrate the use of the route command to obtain network information and the use of nmap and Zenmap to map a networkproper grammar. Navigate to the assignment area for detailed instructions.
This is the link to obtain the Zenmap version. Go to the DOWNLOAD tab, and select your OS (operating system). After downloading, be sure to move the .exe out of the zipped folder first.https://nmap.org/zenmap/

Introduction
The global economy went through a difficult period due to COVID-19. Many businesses did struggle, and some unfortunately failed. While COVID-19 brought immense challenges, it also opened doors for new business and innovative opportunities.
Peloton’s Rise and Fall
Peloton, the high-end at-home fitness company, initially thrived during the early stages of the pandemic. With gyms closed and people stuck at home, demand for their stationary bikes and fitness classes skyrocketed. However, by 2022, they faced significant challenges. They overestimated demand and built-up excess inventory, leading to stockpiling and financial losses. Competitors like NordicTrack and Echelon offered cheaper alternatives, chipping away at Peloton’s market share. Rising inflation and interest rates squeezed consumer spending, making luxury items like Peloton bikes less affordable. Peloton cut expenses, closed stores, and laid off employees to streamline operations. They launched lower-priced bikes and accessories to broaden their customer base. They invested heavily in their app and content offerings, enhancing the virtual fitness experience. Collaborations with retailers like Dick’s Sporting Goods and Amazon expanded their reach. They focused on building community and the emotional benefits of fitness rather than just pushing product sales. While the road was bumpy, Peloton’s efforts are starting to pay off. They’ve reduced their losses, streamlined operations, and are seeing signs of renewed customer demand. The company has shown resilience and adaptability in the face of adversity.
Note: The above-mentioned case study is just an example; students are supposed to find a case study of business that faced significant challenges during the pandemic but found innovative ways to overcome them.
