All questions of Types of Software for Class 9 Exam

Operating System vs. Application Software

An operating system (OS) is the software that manages the hardware and software resources of a computer. It acts as an interface between the user and the computer system, providing various services such as memory management, file management, process management, and security.

On the other hand, application software is a program designed to perform specific tasks for the user. It is installed on top of the operating system and relies on the OS to provide access to the computer hardware.

Answer Explanation

Based on the above definitions, we can determine that Microsoft Word is not an operating system, but an application software. It is a word processing program used for creating, editing, and formatting documents. It requires an operating system to function, and cannot manage the computer hardware and resources on its own.

Therefore, the correct answer is option C, Microsoft Word.

Antivirus Software and Options

Antivirus software is a program designed to detect, prevent, and remove malware (viruses, worms, Trojans, etc.) from a computer or network. It is an essential tool for protecting computer systems from cyber-attacks. Here are the options given in the question:

a) Linux

Linux is not an antivirus software. It is an operating system similar to Microsoft Windows and macOS. However, being an open-source platform, it is less susceptible to malware attacks.

b) Kaspersky

Kaspersky is a popular antivirus software developed by Kaspersky Lab. It offers real-time protection against malware, viruses, spyware, and other cyber threats.

c) Norton

Norton is another well-known antivirus software developed by NortonLifeLock. It provides comprehensive protection against viruses, spyware, malware, and other online threats.

d) Avast

Avast is a free and widely used antivirus software that offers real-time protection against viruses, malware, and other cyber threats.

Conclusion

In conclusion, the correct answer is option 'A' - Linux. Linux is not an antivirus software but an operating system. The other options, Kaspersky, Norton, and Avast, are all popular antivirus software programs that offer protection against various types of malware and cyber threats.

Correct, option 'C' is the correct answer. Library programs are used for controlling the peripheral devices. Peripheral devices are external devices that connect to a computer such as a printer, scanner, or keyboard. Library programs are collections of pre-written code that provide an interface for the operating system to communicate with and control the peripheral devices. These programs are typically written in low-level languages such as C or C++ and are used by developers to create applications that interact with the peripheral devices.

Spreadsheet Tools is the software that helps in organizing and analyzing information in tabular form.

Explanation:
Spreadsheet tools are computer applications that are specifically designed to store, organize, and manipulate data in tabular form. They are widely used in various industries for data analysis, financial modeling, project management, and many other purposes.

Spreadsheet tools provide a grid-like interface where data can be entered into cells, similar to a table. Each cell can contain text, numbers, formulas, or functions. The data can be arranged in rows and columns, creating a tabular structure.

Organizing Information:
Spreadsheet tools offer various features to help organize information effectively. Some of these features include:

1. Sorting: Spreadsheet tools allow users to sort data in ascending or descending order based on specific criteria. This helps in arranging the data in a logical sequence, making it easier to analyze and understand.

2. Filtering: Users can filter data based on specific conditions to display only the relevant information. This helps in focusing on specific subsets of data and identifying patterns or trends.

3. Grouping: Spreadsheet tools allow users to group rows or columns together, making it easier to manage large datasets and perform calculations on subsets of data.

4. Formatting: Users can apply various formatting options to make the data more visually appealing and easier to read. This includes changing font styles, colors, borders, and applying conditional formatting rules.

Analysis of Information:
Spreadsheet tools provide powerful capabilities for analyzing data. Some of the analysis features include:

1. Formulas: Users can create formulas to perform calculations on the data. These formulas can be simple arithmetic operations or complex mathematical functions. Spreadsheet tools support a wide range of functions for statistical analysis, financial calculations, and more.

2. Charts and Graphs: Spreadsheet tools allow users to create visual representations of data using various chart types, such as bar graphs, pie charts, and line graphs. This helps in visually analyzing trends, comparisons, and relationships between different data points.

3. Pivot Tables: Pivot tables are a powerful feature in spreadsheet tools that allow users to summarize and analyze large datasets. They provide a flexible way to aggregate, filter, and analyze data based on different dimensions and criteria.

4. Data Analysis Add-ins: Many spreadsheet tools offer additional add-ins or plugins that provide advanced data analysis capabilities. These add-ins can include features like regression analysis, data mining, and statistical analysis tools.

Overall, spreadsheet tools are essential for organizing and analyzing information in tabular form. They provide a user-friendly interface and a wide range of features to efficiently manage and analyze data.
