___________________ is a program meant to be sent from one computer to another across the world wide Web.

The question describes a small program written so that it can travel from one computer to another over the internet and run inside another program, typically a web browser, once it arrives. This kind of small, portable program embedded in a web page is called an applet.

An applet is designed to be downloaded automatically along with a web page and executed within the browser, adding interactive features such as animations or calculations to what would otherwise be a static page. Mail refers to messages sent between users, not a program in itself; an algorithm is a step-by-step plan for solving a problem, not something that is transmitted and executed; and data packages are simply chunks of data moved across a network, not executable programs.

Exam takeaway: associate the idea of a program sent from one computer to another across the web to be run there specifically with an applet, since it is defined by being both a program and something that travels and executes remotely inside a browser.
