  • Since we rely so much on technology there are huge problems when it goes wrong! If a supermarket checkout system goes down this could result in lost sales of thousands of pounds.However, if an automated system, like those onboard aircraft fails then it could end in disaster!
  • Fundamentals of computer systems

    1. 1. Fundamentals of Computer Systems<br />GCSE Computing Theory<br />
    2. 2. Get your brains logged on!<br />In your books write today’s title “Fundamentals of Computer Systems”.<br />Write down your own definition of what is a computer system.<br />What do you think are the key components of a computer system?<br />
    3. 3. Get your brains logged on!<br />At its very basic, a computer system nothing more than an input, a processor and an output.<br />A system will usually have some storage capability, e.g. a hard drive.<br />More often now a system will have a way of communicating with other devices, e.g. wifi, bluetooth, network adapter.<br />
    4. 4. By the end of this lesson:<br />All of you will be able to define a computer system and describe the importance of computer systems in today’s world.<br />Most of you will be able to explain the need for reliability and adherence to professional standards, use and maintenance of computers systems.<br />A few of you will understand the ethical, environmental and legal impacts of computer systems.<br />
    5. 5. Importance of Computer Systems<br />Computers are all around us and I’m not just talking about your desktop or laptop computer. Your “smartphone”, your games console, your ipad, even your Sky+ or freeview recorder is a computer system of sorts.<br />Computer systems are integral parts of our lives. Working in pairs, list down in your books all the computer systems you or your parents use regularly.<br />
    6. 6. Examples of Computer Systems<br />
    7. 7. System Reliability<br />Go to: http://tinyurl.com/supermarketchaos<br />Read through the web article and answer the following questions in your books:<br />What caused the chaos?<br />What impact did this have on the customers?<br />What impact did this have on the supermarkets affected?<br />How could the supermarkets have prevented or minimised the chaos?<br />
    8. 8. Standards<br />Without standards to adhere to we risk developing systems that are not compatible with each other.<br />Would you be happy if your Nokia mobile could only call other Nokia mobiles? <br />Standards also improve the quality of the computer system and its maintenance by ensuring that best practice is followed and people don’t cut corners.<br />
    9. 9. Legal, Environmental and Ethical considerations<br />
