For Programming Assignment #1 you will be writing your own port scanner. You can use any programming language you choose. The TAs and I have used Python. Your requirements are: 1. Your program must take an input of a target host. It must accept both an IP address or domain name. 2. Your program must take an input of a range of ports. 3. Your program must have a connection timeout so that it will stop trying to connect to a target that is not responding. 4. Your program must print the scan start time. 5. Your code must be commented. Please submit a copy of your code and a screenshot of it working as a PDF file. Then submit your source code (.py, java, etc.) as a second file. Your screenshot should be similar to the one provided below and it should show at least one open and one closed port. Happy coding! :-/Desktop$ python portscan.py Enter a target to scan: 10.1.123.158 Please enter the range of ports you would like to scan on the target Enter a start port: 20 Enter a end port: 30 Scanning started at: 2022-09-25 23:43:26.226827 Port 20 is closed Port 21 is closed Port 22 is open Port 23 is closed Port 24 is closed Port 25 is closed Port 26 is closed Port 27 is closed Port 28 is closed Port 29 is closed Port Scanning Completed

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
