In the digital age, understanding information in computers is crucial. This chapter will explore what information is, examples of information, and its key characteristics. We'll also answer common questions about information in computers.
What is Information in Computers?
Information is data that has been processed, organized, and structured to be useful for decision-making or solving problems. Simply put, processed data becomes information.
Examples of Information
Here are some important examples of information:
- Student report cards
- Train schedules
- Employee pay slips
- Video tutorials on courses like Java
- Quarterly financial statements of companies
Example Explanation:
Consider texts like "Sonu," "Shukla," "Rajneesh," and subjects like "computer science," "math," and numbers like 96, 77, 58. On their own, these are just data points. However, when organized into a student report card, this data becomes information that shows a student's strengths and weaknesses in specific subjects.
