1. Ping

Introduction

The network program was operated with the program version of Pycharm 2019.3.1 (professional edition)

Algorithm:

1. Initiate
2. Network commands test application is opened in a Window.
3. Go to ping address for entering address and select option
4. The command receives address from the program.
5. The address is received by destination
6. If the site is valid
7. Destination sends 4 data packets with verification notification to the command
8. OK signal is send by command to ping the program
9. After that, the users receives four data packets
10. Else
11. Down notification is send by the command in the console program
12. No reply message is received by actor
13. Stop

• Ipconfig/all

Introduction

Pycharm 2019.3.1 was the version of program was used for the program on networking.

Algorithm

1. Initiate
2. Networking Command Test Application open
3. The option Ipconfig/all is choose
4.  Console program request for program
5. Router receives the request command
6. If there is right connection,
7. The command prompt receives all the IP addresses like MAC, DNS and DHCP address
8. The information is provided by command to console program
9. The user view the configuration information displayed by the console
10. If not,
11. Connection down status notification is send by the command to console
12. And no reply message is received by actor
13. End
