1. What is Computer System? How does the Computer System work? Explain with suitable block diagram.
=  Computer System:

          A computer system is a combination of hardware and software components that work together to perform various tasks. It consists of input devices, output devices, a central processing unit (CPU), memory, storage devices, and software. The hardware components receive input, process it using the CPU, and produce output through the output devices. The software provides the instructions and programs necessary for the computer system to perform specific tasks.


Block Diagram of a Computer System:

          A block diagram represents the components of a computer system and their connections. Here is a simplified block diagram of a computer system:


        |    Input Devices |




        |    Central           |

        |    Processing     |

        |    Unit (CPU)    |




        |      Memory       |




        |    Storage          |

        |    Devices         |




        | Output Devices |


- Input Devices: These devices, such as keyboard and mouse, allow users to provide input to the computer system.

- Central Processing Unit (CPU): The CPU is the brain of the computer that executes instructions and performs calculations.

- Memory: It stores data and instructions that are currently being processed by the CPU. It includes RAM (Random Access Memory) and cache memory.

- Storage Devices: These devices, like hard drives and solid-state drives, provide long-term storage for data and programs.

- Output Devices: Devices like monitors and printers display or present the results of the computer's processing.

The computer system works by receiving input from the user through input devices, processing the input using the CPU and memory, accessing data and instructions from storage devices, and producing output through output devices. The software provides the necessary instructions for the CPU to perform specific tasks, and the hardware components facilitate the execution of those instructions.

2. Make a list of any ten MS-DOS commands with their functions.
= Here are ten MS-DOS commands with their functions:

1. DIR: Lists the files and directories in the current directory.

2. CD: Changes the current directory.

3. MD: Creates a new directory.

4. RD: Removes an empty directory.

5. COPY: Copies files from one location to another.

6. DEL: Deletes files.

7. REN: Renames files.

8. TYPE: Displays the contents of a text file.

9. FORMAT: Formats a disk or drive.

10. CHKDSK: Checks a disk for errors and displays a status report.

3. What is the difference between a Word Processor System and Electronic Spreadsheet? Give few application of each.

= Difference between a Word Processor System and Electronic Spreadsheet:

Word Processor System:

- A word processor system is designed for creating, editing, formatting, and printing textual documents.

- It focuses on manipulating text and provides features like spell checking, formatting options, page layout, and document organization.

- Applications: Writing letters, reports, essays, creating resumes, etc.


Electronic Spreadsheet:

- An electronic spreadsheet is used for organizing, analyzing, and calculating numerical data.

- It consists of cells organized in rows and columns, allowing for mathematical formulas, data manipulation, and data visualization.

- Applications: Budgeting, financial analysis, data management, creating charts and graphs, etc.


Both word processor systems and electronic spreadsheets are productivity tools commonly used in office environments. They serve different purposes and have distinct features tailored to specific tasks.

Best of Luck!
