Explanation:
To determine if you can reach the router, you should use thepingcommand followed by the IP address of the router. Thepingcommand is a network utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.
The Default Gateway in theipconfigresults is typically the router's IP address in a home or small office network. In this case, the Default Gateway is192.168.0.1, which is the address you would ping to check connectivity to the router.

To determine if you can reach the router, you should use thepingcommand with the IP address of the router.
* Command:ping
* Target:192.168.0.1
So, the completed command is:
* ping 192.168.0.1
Step by Step Comprehensive and Detailed Explanation:
* ping: The ping command sends ICMP Echo Request messages to the target IP address and waits for an Echo Reply. It is commonly used to test the reachability of a network device.
* 192.168.0.1: This is the IP address of the default gateway (the router) as shown in theipconfigoutput.
Pinging this address will help determine if the computer can communicate with the router.

Explanation:
The correct matching of the security options to their characteristics is as follows:
* WPA2-Enterprise: Uses a RADIUS server for authentication
* WEP: Uses a minimum of 40 bits for encryption
* WPA2-Personal: Uses AES and a pre-shared key for authentication
Here's why each security option matches the characteristic:
* WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.
* WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.
* WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network.
These security options are essential for protecting wireless networks from unauthorized access and ensuring data privacy.
