explore a user-started process. a. open a web browser, such as microsoft edge. what did you observe in the tcpview window?
The Correct Answer and Explanation is :
When you start a web browser like Microsoft Edge and observe the TCPView window, you’ll notice several key details regarding network connections that the browser initiates and maintains.
Observations in TCPView
- Active Connections: As soon as Microsoft Edge is opened, TCPView will display multiple active connections. This includes connections to various IP addresses corresponding to the websites you visit. Each connection is represented by a line showing the local and remote addresses, the protocol being used (usually TCP), and the state of the connection (e.g., ESTABLISHED, LISTENING, TIME_WAIT).
- Local and Remote Addresses: The local address represents your computer’s IP address, while the remote address is the server’s IP address that Edge connects to. For example, if you open a news website, you’ll see your local IP connecting to the server hosting the site.
- Port Numbers: Each connection will include port numbers. Web browsers typically use port 80 for HTTP connections and port 443 for HTTPS connections. You might see connections to these ports as Edge establishes secure connections to ensure safe data transmission.
- Process Identification: TCPView allows you to identify the specific process responsible for each connection. You can see Microsoft Edge listed as the process name, showing which instances of Edge are creating network connections.
Explanation
The TCPView utility from Sysinternals provides real-time information about TCP and UDP connections on your computer, allowing you to monitor network activity effectively. When you launch a web browser, it immediately begins establishing connections to retrieve web content. This includes not just the main page but also various resources like images, scripts, and advertisements.
The numerous connections observed in TCPView can be attributed to how modern web pages function, often relying on content from multiple servers to load a single webpage fully. These connections may also show how the browser handles different tasks, such as preloading resources or maintaining persistent connections for faster load times.
Overall, TCPView serves as a powerful tool to visualize and analyze the networking behavior of applications, providing insights into the data exchange between your system and external servers, which is crucial for understanding network performance and troubleshooting connectivity issues.
