Unit Summary
In this unit pupils will discover the difference between general purpose and embedded systems. They will examine computer architecture and the components that make up a processor. Pupils will recognise the need for storage and be able to select a suitable storage device for a given purpose.
Lesson Summary
You will learn to describe the differences between embedded and general purpose computer systems and the role of application and utility software.
Key Notes
- An embedded computer system has a specific task or set of tasks to complete.
- A general purpose computer system has a range of purposes defined by a user interaction.
- Application software is developed to perform end-user tasks.
- Utility software manages specific tasks on a computer system.
Vocabulary To Learn
- general purpose computer: a computer designed to perform many different tasks
- embedded computer: a small computer built into a device to control specific functions
- utility software: helps maintain and improve the performance of a computer system
- application software: software used by humans to complete a task
Common Mistakes To Avoid
- Embedded system is a computer inside a computer / system inside a system.
