Write a small Ping CLI application for MacOS or Linux. The CLI app should accept a hostname or an IP address as its argument, then send ICMP "echo requests" in a loop to the target while receiving "echo-reply" messages. It should report loss and RTT times for each sent message. Please write it in C++.Also, how would you add support for both IPv4 and IPv6. Allow to set TTL as an argument and report the corresponding "time exceeded" ICMP messages.1. Build a tool with a CLI interface - The tool should accept as a positional terminal argument a hostname or IP address.2. Send ICMP "echo requests" in an infinite loop - As long as the program is running it should continue to emit requests with a periodic delay.3. Report loss and RTT times for each message - Packet loss and latency should be reported as each message received.

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
