Computer Science

a computer designed to perform many different tasks

a small computer built into a device to control specific functions

helps maintain and improve the performance of a computer system

software used by humans to complete a task

Software and embedded systems

Operating system

The processor

The fetch-execute (FE) cycle

Main memory

Secondary storage

Computer specifications

Environmental impacts of computing devices

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.

Computer Systems

to perform a wide range of tasks defined by the user

to control specific functions within a device

to manage the performance of a computer system

What is the main purpose of an embedded computer system?

a computer built into a device to control specific functions

a computer that only runs utility software

a computer that cannot run application software

What is a general purpose computer system?

Which of the following is an example of application software?

to create new applications for a computer

to manage and maintain the performance of a computer system

because it is a computer inside a computer

because it operates independently of other systems

because it is only found in general purpose computers

because it is designed to control specific functions within a machine

Why is an embedded system not considered a system inside a system?

embedded technology used in factories for precision tasks

application software used to create and edit documents

utility software that protects a computer from malware

What is the term for the programs and applications that run on a computer?

the programs and applications on a computer

What does hardware refer to in computing?

Which of the following is an example of hardware?

Which of these is an example of specialised technology?

data entered into a system, such as using a keyboard or sensor

the action of transforming or manipulating data within a system

the result produced by a system, such as a printed document or display

hardware and software working together to process data

Which of the following best describes a computer system?
