This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will explore computer systems and how information is transferred between devices. They will explore the input, output and processes of a variety of different real-world systems. Pupils will discover how information is found on the WWW through learning how search engines work.
Lesson Summary
You will learn to explain how search results are ranked.
Key Notes
- Search engine indexes can be ordered by rank.
- Search engines follow rules to rank results.
- Search engines use different criteria to rank results.
Vocabulary To Learn
- rank: the order search results appear in, based on how useful and relevant they are
- algorithm: a precise set of ordered steps, which can be followed by a human or a computer to do a task
Common Mistakes To Avoid
- There is no order to the results given by a search engine, it is just whichever results have been found first.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Search engine indexes can be ordered by rank. Search engines follow rules to rank results.
2. Define this computing term and give one practical example. 'rank'
the order search results appear in, based on how useful and relevant they are. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: There is no order to the results given by a search engine, it is just whichever results have been found first. Correction: Search engines order results following algorithms or rules to move some results nearer the top of the results list.
