Platform for Internet Content Selection

Platform for Internet Content Selection is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Platform for Internet Content Selection rather than just read about it. In short: The Platform for Internet Content Selection (PICS) was a specification created by W3C that used metadata to label webpages to help parents and teachers control what children and students could access on the Internet. The W3C Protocol for Web Description Resources project integrates PICS concepts with RDF.

Key takeaways

Platform for Internet Content Selection belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Platform for Internet Content Selection to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Platform for Internet Content Selection from memory before moving on to harder problems.

Reference excerpt

The Platform for Internet Content Selection (PICS) was a specification created by W3C that used metadata to label webpages to help parents and teachers control what children and students could access on the Internet. The W3C Protocol for Web Description Resources project integrates PICS concepts with RDF. PICS was superseded by POWDER, which itself is no longer actively developed. PICS often used content labeling from the Internet Content Rating Association, which has also been discontinued by the Family Online Safety Institute's board of directors. An alternative self-rating system, named Voluntary Content Rating, was devised by Solid Oak Software in 2010, in response to the perceived complexity of PICS. Internet Explorer 3 was one of the early web browsers to offer support for PICS, released in 1996. Internet Explorer 5 added a feature called approved sites that allowed extra sites to be added to the list in addition to the PICS list when it was being used.

Worked examples

Example 1 — a first encounter with Platform for Internet Content Selection

Start with the simplest possible case. Write down what Platform for Internet Content Selection claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Platform for Internet Content Selection before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Platform for Internet Content Selection ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Platform for Internet Content Selection

In research: Platform for Internet Content Selection appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Platform for Internet Content Selection in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Platform for Internet Content Selection is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer law, Internet Explorer add-ons, Internet access, so understanding it makes those chapters shorter.
In everyday life: Look for Platform for Internet Content Selection outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
