What is an information system? What is its purpose? Give an example of how using origination, change, distribution, storage, and deletion of information is managed and secured.

An information system is a combination of people, processes, and technology that an organization uses to manage and process information. It's a structured set of components for collecting, storing, processing, and communicating different types of information.

The purpose of an information system is to help an organization manage its business processes and make informed decisions by providing timely and relevant information. It also helps in maintaining efficiency, improving productivity, supporting strategic goals, and gaining competitive advantages.

For example, a hospital's information system manages and secures information through the following steps:

1. Origination: Information is generated from various sources like patient records, lab results, and medical history. This information is entered into the system by healthcare professionals.

2. Change: The information in the system is updated as and when changes occur. For instance, when a patient's health condition changes, doctors update the patient's records in the system.

3. Distribution: The information is shared with relevant parties. For example, a doctor can access a patient's medical history from the system when needed. The system ensures that only authorized individuals have access to this information.

4. Storage: The information is stored in secure databases. The hospital's information system uses data encryption and other security measures to protect the information from unauthorized access and data breaches.

5. Deletion: When information is no longer needed, it is securely deleted from the system. The system ensures that the information is permanently deleted and cannot be recovered.

In this way, the hospital's information system manages and secures the origination, change, distribution, storage, and deletion of information.
