  1. GCSE Computing

  2. Course Aims • This course will help you understand the latest technologies & how they work. • You will lean how to develop computer programs to solve problems.

  3. The average salary for jobs in Computing is £37,500 That is a VERY GOOD salary!

  4. Course Content • Unit A451: Computer Systems and Programming Exam – 90 mins – 40% • Unit A452: Computing Controlled Assessment – Approx. 20 hours – 30% • Unit A453: Programming Controlled Assessment – Approx. 20 hours – 30%

  5. You can get an A*-G grade Your writing is also marked! Make sure your writing can be read and your spelling, punctuation and grammar are accurate

  6. Unit A452: Computing Practical Investigation • Practical activity • Investigate real world examples of computers in use • Technical understanding • Creatively solving problems • Testing, evaluation and conclusions

  7. Unit A453: Programming Programming project • Programming techniques • Programming solutions to problems • Design • Development • Testing & Evaluation

  8. Unit A451: Computer Systems & Programming • Representation of data in computer systems • Units • Number • Character • Images • Sounds • Instructions • Programming • Algorithms • Programming languages • Control flow in imperative languages • Handling data in algorithms • Testing • Computer communications and networking • Networks • The internet • Computing hardware and software • The Central Processing Unit (CPU) • Binary logic • Memory • Input and output devices • Secondary storage • Databases • The database concept • The DBMS • Relational databases • Computer systems • Legal issues • Reliability

  9. Computer Systems • Computers are all around us in one shape or another • How many different types of computer systems can you find in this room? Don’t forget anything that might be in your bag! • Mobile phone • Calculator • Projector • Laptop • Computers • Printer • Watch • MP3 players, digital television sets, satellite navigation systems • etc.

  10. What happens when data in input? When data is entered it is converted to binary (1s and 0s) and then processed How do we input data? Input devices are used to enter data. E.g Mouse, Keyboard, Webcam. How is data stored? Data can be stored in hard disk drives, or portable media such as USB Drive How is data output? Information can be output on the screen, speaker, projector etc Can we share data? Networked computers can share information and resources. We can also use the internet

  11. In groups • Use the A3 sheet to complete the mind map. • Each group is given a different computer system. Discuss and explore • How data is input • How data is processed • How data is stored • How information in output • How we can communicate with other devices

  12. Computer Systems • INPUT • PROCESS • OUTPUT • A system is a collection of parts that work together for a common purpose. • For a system to be useful, it must produce something – an output. • It needs to receive and process inputs in order to produce outputs.

  13. Embedded Systems • 5 minutes • Use the internet to search for a definition of an Embedded System • Share with the class

  14. Embedded Systems • Software that is programmed to carry out a number of dedicated functions. For example, the software to run a washing machine is stored on a computer chip and embedded into the system.
