Lesson Sustainability and Environment Protection

Sustainbility refers to the ability to use the resources for a long period of time (if not forever), i.e. resources such as raw materials for making computers and printers, and even printing paper. Green ICT is the goal for everyone, for the sake of everyone on this planet.

Lesson 2 Health And Safety Issues

LOs: health and safety risks and prevention as a user; as a practitioner.

Health and Safety Issues as a User

Describe the problems, symptoms and prevention methods, for example, Repetitive Strain Injury (RSI), the pain and ache at the joints such as wrists, swelling, loss of control. It can be prevented by taking regular breaks, using wrist support, using ergonomically designed keyboard.

Health and Safety Issues as a Practitioner

Legal and Executive Guidelines (e.g. HSE)

Researh and summarise two pieces of legislations and guidelines related to health and safety. (handling electricity, display equipment, ...)

What is HSE? Guess from this news item last week: "A North Yorkshire coal mine has suffered a roof collaps yesterday and one miner was killed on spot. Police and HSE have started the investigation."

Lesson 1A Case Study - A Broken Laptop

 

Lesson 1 Why Maintenance and Why Scheduling

Starter: describe a problem you have had when using computers. (individual, group, then class)

 

The basic concepts

Maintenance:

  • To ensure the system run smoothly, the upkeep of the system
  • To troubleshoot and repair any problems with the system
  • To upgrade to enhance the performance of the system

Why is it important to maintain computer systems?

The importance of maintenance is shown when the system breaks down.

Routine maintenance tasks - regular maintenance tasks

Non-rountine tasks - tasks that are carried out ad-hoc, on demand.

Scheduling/plannig

Plan the tasks by setting the time, nature of the task and who is to do it.

Scheduling tasks for computer to do it automatically has many benefits.

 

Activity: in groups describe the problems, possible solutions and determine if it could be a routine or non-rountine task if it could be scheduled for computer to do it automatically.
