Digital Technologies: Unit 4 (D/615/1618)
Programming involves describing processes and procedures which are derived from algorithms. The ability to program is what sets apart a developer and an end user. Typically the role of the developer is to instruct a device (such as a computer) to carry out instructions; the instructions are known as source code and is written in a language that is converted into something the device can understand. The device
executes the instructions it is given.
Algorithms help to describe the solution to a problem or task; by identifying the data and the process needed to represent the problem or task and the set of steps needed to produce the desired result.
Programming languages typically provide the representation of both the data and the process; they provide control constructs and data types (which can be numbers, words, and objects, and be constant or variable).
The control constructs are used to represent the steps of an algorithm in a convenient yet unambiguous fashion. Algorithms require constructs that can perform sequential processing, selection for decision-making, and iteration for repetitive control. Any programming language that provides these basic features can be used for algorithm representation.
This unit introduces students to the core concepts of programming with an introduction to algorithms and the characteristics of programming paradigms. Among the topics included in this unit are: introduction to algorithms, procedural, object-orientated & event-driven programming, security considerations, the integrated development environment and the debugging process.
- LO1 Define basic algorithms to carry out an operation and outline the process of programming an application
- LO2 Explain the characteristics of procedural, object-orientated and event-driven programming
- LO3 Implement basic algorithms in code using an IDE
- LO4 Determine the debugging process and explain the importance of a coding standard.
