Today, if we just want to browse the web, we can do almost everything with one program - a web browser. A browser is one kind of 'net interface'. Net interfaces are programs which sit between you and the internet and help you and the Net make sense to each other. The browser takes care of the technical details of connecting you to the web, and makes sure that the information from the internet arrives in a way that makes sense to you. It also finds out what you want to do, and passes on the information in a way that the internet can understand.
Websites are built in different ways. Pages that contain a lot of information but are not very interactive are called 'static' pages. These are usually written in a language called HTML (HyperText Markup Language). Interactive pages can be written in VBS (Visual Basic Script) or in JavaScript. Because it can be dangerous to run unknown programs, many interactive websites today use interactive scripts that don't run on your computer. These scripts often use a language developed for Personal Home Pages (php)
Avui, si nomes volem navegar per la web, podem fer-ho casi tot amb un sol programa - un navegador de web. Un navegador es un tipus de "interficie web". Interfícies web son programes que estan entre tu i l'internet que t'ajuden a tu i a web perque us pogueu entendre. El navegador s'encarrega dels detalls tècnics de connectar-te a la web, i fa que la informació de l'internet arribi d'una manera que el puguis entendre.
També troba lo que vols fer, i passa la informació d'una manera que l'internet ho pogui entendre.
Pàgines web estàn fetes de differents maneres. Pàgines que contenen molta informació però no son molt interectius s'anomenen pàgines 'estàtiques'. Aquestes normalment estàn escrites amb un llenguatge anomenat HTML (HyperText Markup Language). Pàgines interactives es poden escriure amb VBS (Visual Basic Script) o amb JavaScript. Com que pot ser perillós executar programes desconeguts, moltes pàgines web avui en dia fan servir scripts interactius que no s'executen en el teu ordinador. Aquest scripts fan servir un llenguatge desenvolupat per Personal Home Pages (PHP).
