    1. BTEC Level 2 Certificate/Diploma in Information Communication Technology (ICT) Practitioners Unit 2: Introduction to Computer Systems

    2. Types of computers PC (base unit, monitor, keyboard, mouse). Server. Embedded devices (e.g. inside phones, washing machines, cars, games consoles). Others (e.g. Mainframe, PDA).

    3. Users Home/commercial end users and IT practitioners (e.g. software and website developers, administrators, help desk workers and technicians). Types of task that users might perform on a computer. Levels of technical expertise users might need.

    4. User interface: Command line operating system (e.g. MS-DOS, Linux). Graphical User Interface (GUI) (e.g. Microsoft Windows). Specialised (e.g. voice controlled). Advantages and disadvantages of different types.

    5. Hardware Processor speed and type. Memory (e.g. RAM, cache). Storage devices (e.g. hard disk drive, floppy drive, CD-ROM, flash drive, DVD). Input devices (e.g. graphics tablet, microphone, mouse, keyboard). Output devices (e.g. printer, monitor). Modems (e.g. dialup, broadband). Network interface cards. Costs.

    6. Performance Characteristics of component (e.g. processor speed and type). Data transmission speeds.

    7. Data representation :Binary. Bits and multiples (e.g. megabytes, gigabytes).

    8. Logical representation of a PC system Simple block diagram.

    9. Systems software Operating systems. Systems software tools (e.g. diagnostic tools, file managers, disk utilities).

    10. Applications software Features of office applications software (e.g. word-processing, spreadsheets, database, graphics, presentation and communication).

    11. Compatibility Hardware and software.

    12. Health and safety Electrical hazards. Manual handling. Impact on users (e.g. RSI, eyestrain).

    13. Working practices Working procedures. Assess and minimise risk. Obtaining resources. Recording relevant information. Communicating progress and outcomes.

    14. Hardware connections Connection of peripheral devices to a PC system (e.g. speakers, digital camera, scanner, web cam, barcode reader, graphics tablet). Appropriate cabling. Testing functionality.
