National 5 Computing Science

The iterative development process every software solution in this course is built through: analysis, design, implementation, testing, documentation, and evaluation.

The five data types every National 5 program is built from, and the 1-D array, the course's one required data structure for storing multiple related values.

The three building blocks every program's control flow is made from: sequence, selection, and iteration, plus the predefined functions the course requires.

Arithmetic operators and expressions, and string concatenation, the course's required operations for combining values and text.

The three standard algorithms the course requires: input validation, a running total within a loop, and traversing a 1-D array.

Normal, extreme, and exceptional test data, the three categories of program error, and why internal commentary and other documentation matter.

How numbers, text, and both vector and bit-mapped graphics are ultimately stored in binary, and what determines the storage size each one needs.

The CPU's core components, how they're linked by buses, memory locations with unique addresses, and why interpreters and compilers are needed.

The energy use of computer systems, and three specific settings that can reduce it.

The role of firewalls, and the use of encryption in electronic communications, the course's two required security precautions.

How an information system's requirements are identified and captured, before any database or website is actually built.

Implementing a two-table relational database with referential integrity, and the SQL operations used to query and update it.

The named HTML tags, CSS properties, and JavaScript mouse events the course requires, and how hyperlinks address other pages.

UK GDPR and the Copyright, Designs and Patents Act 1988, plus the environmental and security considerations specific to an information system.
