ITPEC FE Morning April 2023 Question 10

Java servlet — a Java program that runs on the web server and builds dynamic responses to HTTP requests.

A servlet runs inside a servlet container on the web server, such as Tomcat. For each request it can read form data, query a database and generate an HTML page; the browser receives only the result, and no part of the servlet runs on the client.

Answer (c)

Why not others:

• •(a) JavaScript — runs mainly in the browser, on the client side; it can also run on a server, but it is not limited to one
• •(b) Java applet — a Java program downloaded into the browser and run there: the client-side counterpart of a servlet
• •(d) VBScript — mainly a client-side script language for Internet Explorer; it also ran in classic ASP pages, so it is not server-only either

Key rule: The suffix tells the side: an applet runs in the browser, a servlet on the server.
