(a) Define Information Processing.
(b) State four steps involved in information processing.
(c) Mention three advantages of using computers for information processing.
(d) Highlight three disadvantages of using computers for information processing.
(a) Information processing is the manipulation of data or information using a computer or other electronic devices. It involves the input, processing, output, and storage of data.
(b) The four steps involved in information processing are:
1. Input: This is the process of gathering and entering data into a computer or other electronic device. Input can be done through various methods, such as keyboard, mouse, scanner, microphone, or camera.
2. Processing: This is the stage where the computer or device analyzes, organizes, and manipulates the input data using algorithms and programming logic. Processing can involve tasks such as calculations, sorting, filtering, or searching for specific information.
3. Output: This is the stage where the processed data is presented to the user in a readable and usable format. Output can be in various forms, such as text, graphics, images, or sound.
4. Storage: This is the stage where the processed data is saved and stored for later use. Storage can be done on various devices, such as hard drives, flash drives, or cloud storage.
(c) Three advantages of using computers for information processing are:
1. Speed: Computers can process large amounts of data quickly and efficiently, saving time and increasing productivity.
2. Accuracy: Computers are less prone to errors than manual processing, ensuring data accuracy and reducing the risk of mistakes.
3. Accessibility: Computers allow for easy and quick access to information, making it easier to share and collaborate with others.
(d) Three disadvantages of using computers for information processing are:
1. Dependence: When relying on computers for information processing, there is a risk of system failure, which can lead to loss of data and disruption of work.
2. Security: Storing and processing sensitive information on computers can make it vulnerable to cyber-attacks and data breaches.
3. Cost: Computers and software required for information processing can be expensive, and ongoing maintenance and upgrades can add to the overall cost.
