Here are the solutions to the questions: 1. a) i) Data processing Data processing is a series of actions or operations carried out to collect, organize, manipulate, and convert raw facts (data) into meaningful information. 1. a) ii) Data collation Data collation is the systematic arrangement of data collected in machine-readable form in preparation for input into the computer. 1. b) Description of Data Processing Cycle The Data Processing Cycle is the sequence of stages involved in transforming raw data into meaningful information. It typically comprises four main stages: input, where data is collected; processing, where data is manipulated; output, where processed information is presented; and storage, where data and information are saved. An optional fifth stage is feedback, which involves evaluating the output and making adjustments to the process. 1. c) Benefits of the computer as a tool for processing data • Computers support a high speed of operation, processing data much faster than manual methods. • They offer high storage capacity, allowing vast amounts of data to be stored and accessed. • The use of computers leads to increased accuracy in data handling and calculations. • Computers can handle repetitive tasks and large volumes of work consistently without fatigue. • They enhance fast data retrieval and improve overall reliability in data management. 2. a) The parts labelled in Figure I are: • A - Monitor/ Visual Display Unit: This is an output device. • B - Printer: This is an output device. • C - Mouse: This is an input device. • D - Keyboard: This is an input device. 2. b) Complete the table for Device type Given that Device A and Device B are both output devices (as indicated by the checkmark in the 'Output' column), they do not function as input devices. Therefore, the 'Input' column for both devices remains empty. |c|c|c| Device & Input & Output \\ A & & \\ B & & \\ Send me the next one 📸
