- Explain Volatile and Non-Volatile memory.
Ans 2.
Volatile and Non-Volatile Memory
Memory in a computer system is critical for storing data, instructions, and the results of computations. It can be broadly categorized into two types: volatile and non-volatile memory. Both types serve specific purposes within the computer system, and their characteristics determine how they are used in different contexts. Below is a detailed explanation of volatile and non-volatile memory.
Volatile Memory
Volatile memory is a type of computer memory that requires a constant power supply to
- What is the difference between Input and Output Devices?
Ans 3.
Difference Between Input and Output Devices
Input and output devices are fundamental components of a computer system, enabling users to interact with the machine and access its results. These devices bridge the gap between the user and the computer, allowing data to be fed into the system and processed results to be delivered back. Below is a detailed explanation of input and output devices and the differences between them.
Input Devices
Input devices are hardware components used to enter data, commands, and instructions into a

- Briefly explain the software development process.
Ans 4.
Software Development Process
The software development process is a systematic approach to designing, creating, testing, and maintaining software applications. It involves a series of well-defined stages to ensure the delivery of high-quality software that meets user requirements. The process is typically guided by a specific development methodology, such as Agile, Waterfall, or DevOps. Each stage plays a critical role in transforming an idea into a fully functional software product.
- Requirement Analysis
The process begins with gathering and analyzing user requirements. This involves
- Explain the different stages in Software Testing.
Ans 5.
Stages in Software Testing
Software testing is a critical phase in the software development lifecycle, focusing on evaluating the software’s functionality, performance, and reliability. The objective of testing is to identify defects and ensure that the software meets specified requirements. The process involves multiple stages, each designed to address specific aspects of quality assurance.
- Requirement Analysis
The testing process begins with analyzing the requirements to identify testable aspects of the
- Describe the various Computer Generations.
Ans 6.
Computer Generations
The evolution of computers has been categorized into five distinct generations, each marked by significant technological advancements. These generations illustrate the progression of computer technology from mechanical systems to modern, AI-driven devices. Below is an overview of the various computer generations and their defining characteristics.
