Data in DBMS:  Data is raw facts or unprocessed values. It can be in the form of numbers, characters, symbols, images, graphics, etc. Data is input given to the computer by the users. It is meaningless on its own. Example : 10061995 - Just a number (we don't know what it means). Information in DBMS: Processed data is called information. It is meaningful and useful. Information can be reused multiple times. Example: 10061995- If we know it's someone's date of birth, it becomes meaningful information. What is Database? A database is an organized collection of data that can be easily accessed, managed, and updated.  Key points: Database stores data in a structured form (like tables). It helps in quick retrieval and processing of data. Data in a database can be added, deleted, modified, and searched easily. Example: A school database may store: (Student names, Roll numbers, Marks and Addresses).  A library database stores(Book names, Author names, and Borrower's details). ...

Introduction to Computer? The word Computer comes from the word Compute, which means to count or to calculate. A computer is an electronic device that takes input from the user, processes the data, and gives the desired result(output). It performs both mathematical and non-mathematical operations.                                       A computer follows the principle of GIGO (Garbage In, Garbage Out), which means if incorrect input is given, the output will also be incorrect.  Characteristics of Computer: Speed: Computers work very fast. They can perform millions or even billions of instructions in one second. Tasks that take hours for humans can be completed in seconds or milliseconds.             Example: Solving thousands of mathematical problem in a few seconds.  Accuracy : A computer is highly accurate. It gives correct results if the in...
