Introduction“It is certainly correct to say that computers have become as integral a part of modern life as fast food, mobile phones and sports utility vehicles.” (Joe, 2004) We live in the age of information exchange. It has changed radically compared to the last few decades. How could this happen? The answer will be the network. A network can be anything from a simple collection of computers in one location that have been linked together using a particular means of connectivity (such as network cabling) to a giant global network, such as the Internet, that uses several means of connectivity several, including microwave and satellite. technology. One day the network will fall apart, which will be a disaster for us. Therefore, we should know what will cause potential network failures when this happens. Nowadays, it should have a physical network server if we need to connect to the Internet. However, there is a new technology called virtual servers, developed by Microsoft that will also be explored. For a network, security is a priority. As a large manufacturing company that has many factories in different regions, how to maintain the reputation of your business? How to convince customers that operations are safe? Finally, it should be considered how to handle sensitive data, which is the other issue. Chapter I: Potential Network Failures and Solutions To keep your network healthy, you need to monitor network traffic and observe various processes and events related to network protocols. , which means it should be ready to setup some potential network errors. There are several factors that cause network failure. Below will be the main problems that cause network failure:I.
