What are fourth generation languages?
Fourth-generation languages (4GLs) are high-level programming languages designed to be more user-friendly and efficient than earlier generations. They allow developers to create applications with less code and often include features for database manipulation, report generation, and user interface design. 4GLs are typically more abstract, focusing on what the program should accomplish rather than how to execute it, thereby enhancing productivity and reducing development time. Examples of 4GLs include SQL, MATLAB, and various scripting languages.

What statement regarding crossover cables is accurate?
Crossover cables are used to directly connect two similar devices, such as two computers or two switches, without the need for a hub or switch in between. They work by crossing the transmit and receive wires, allowing for proper communication between the devices. While modern networking equipment often auto-senses connections and can adjust accordingly, crossover cables are still essential for certain older devices that do not support auto-MDI/MDI-X functionality.

· data logging, e.g. using sensors to record variables such as temperature, moisture, light and pressure, to assist in the recording, presentation and analysis of results so that pupils can spend more time on interpretation, evaluation and the formulation of hypotheses about the implications
· simulations and modelling, to help pupils understand phenomena which may be too slow, too fast, too dangerous or too expensive to investigate in the school laboratory, and to allow them to investigate the effects of changing variables in the situations represented or to consolidate and reinforce conceptual understanding
· databases and spreadsheets, to enable pupils to organise, search and sort information in order to explore relationships, look for patterns and test hypotheses, e.g. extracting data on the nutrient value of different foods
· publishing and presentation software, e.g. word processing and desktop publishing packages and multimedia authoring software, to enable pupils to develop understanding and present their findings to others
· information resources, e.g. the internet, CD-ROM and data files, to enable pupils to find information and thus to develop their knowledge and understanding of science.
Transportation:
