This subject is optional and is assessed as the Cadet must prove that they are competant with using the internet. Simple exercises will be set so that the Cadet can prove that they are competant with using e-mail, FTP programs, search engines and web browser usage. A simple web site will also need to be constructed which may be added to the Squadron web site when they are finished. Help with these exercises will be available through the Sqn Web Master and/or SCO. Additional areas that are also taught include TCP/IP addressing, DNS and the need for firewalls & antivirus protection. The Sqn computer network is used here as a teaching aid giving the Cadets valuable experience of modern day problems of using the internet.
