Computer Science

includes discarded electronic devices like phones, laptops and batteries

a computer that stores, manages and shares files, data and resources in a network

facility that houses servers, storage systems and networking equipment to store, process and distribute data

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

Cloud data is stored in the air and does not use any physical equipment.

Cloud data is kept in large facilities that use electricity and cooling.

Cloud data only exists on your personal device.

Cloud data is stored in underwater cables.

Which of the following statements is accurate about where cloud data is stored?

What is the term for discarded electronic devices like laptops and phones?

Put these steps in order for what happens when a device is thrown away:

Which device is considered e-waste when discarded?

Match each environmental impact to its source:

What happens when e-waste is not properly managed?

number of cycles per second, measured in gigahertz

onboard memory of the CPU, measured in megabytes

Put these components in order from smallest to largest typical size:

What term describes a CPU with four independent processing units?

If the clock speed of a CPU is increased but the RAM cannot keep up, what might happen?
