procedural high-level languages: integer, real, char, string, Boolean, date (pseudocode will use the following data types: INTEGER, REAL, CHAR, STRING, BOOLEAN, DATE, ARRAY, FILE CPU Architecture Show understanding of the basic Von Neumann model for a computer system and the stored program concept
System Software –Operating Systems Show understanding of how data are transferred between various components of the computer system using the address bus, data bus and control bus Describe why a computer system requires an operating system
System Software –Utility Programs
Hardware – Input, Output and Storage Devices Explain the key management tasks carried out by the operating system Show an understanding of the need for typical utility software used by a PC computer system: • Disk formatter • Virus checker • Defragmenter software • Disk contents analysis/disk repair software • File compression • Backup software Identify hardware devices used for input, output, secondary storage
Memory Show understanding of the basic internal operation of the following specific types of device: • Keyboard • Trackerball mouse • Laser mouse • Scanner • Sensors • Actuators • Inkjet printer • Laser printer • Speakers • Optical disks • Hard disk • Flash memory Explain the differences between RAM and ROM memory
Explain the differences between Static RAM (SRAM) and Dynamic RAM (DRAM) Logic Gates Understand and define the functions of NOT, AND, OR, NAND, NOR and XOR (EOR) gates including the binary output produced from all the possible Describe and understand the fundamental structure of the CPU
Understand the need for an operating system and describe some of the roles it can perform
binary inputs (all gates, except the NOT gate, will have two inputs only) Construct a logic circuit from either: • a problem statement, or • a logic expression Construct a truth table from either: • a logic circuit, or • a logic expression

Design & Technology
Aims and Objectives
Design and Technology prepares pupils to participate in tomorrow’s rapidly changing technologies. They learn to think and intervene creatively to improve the quality of life. The subject calls for the pupils to become autonomous and creative problem-solvers, as individuals and as members of a team. They must look for needs, wants and opportunities and respond to them by developing a range of ideas and making products and systems. They combine practical skills with an understanding of aesthetics, social and environmental issues, function and industrial practices. As they do so, they reflect on and evaluate present and past design and technology, its uses and effects. Through Design and Technology, all pupils can become discriminating and informed users of products, and become innovators.
