Generations of Computer Video Lecture | SBI PO Prelims & Mains Preparation - Bank Exams

Ans. The different generations of computers are as follows: - First Generation (1940s-1950s): These computers used vacuum tubes for circuitry and were very large and expensive. - Second Generation (1950s-1960s): These computers used transistors instead of vacuum tubes, making them smaller, faster, and more reliable. - Third Generation (1960s-1970s): This generation saw the development of integrated circuits, which further reduced the size and cost of computers. - Fourth Generation (1970s-1980s): The development of microprocessors revolutionized computing, allowing for the creation of personal computers. - Fifth Generation (1980s-present): This generation is characterized by the use of artificial intelligence and advanced parallel processing.

Ans. The main improvements in each generation of computers are as follows: - First Generation: The main improvement was the use of vacuum tubes, which made computers more reliable and faster than their predecessors. - Second Generation: The main improvement was the use of transistors, which made computers smaller, faster, and more reliable. - Third Generation: The main improvement was the development of integrated circuits, which reduced the size and cost of computers. - Fourth Generation: The main improvement was the development of microprocessors, which revolutionized computing by allowing for the creation of personal computers. - Fifth Generation: The main improvement is the use of artificial intelligence and advanced parallel processing, which enables computers to perform complex tasks and process large amounts of data.

Ans. The development of each generation of computers had significant impacts on society. Here are some examples: - First Generation: The use of vacuum tubes allowed for the creation of large-scale computers, which were used primarily by the military and scientific community for calculations. - Second Generation: The use of transistors made computers smaller and more affordable, leading to their increased adoption in businesses and universities. - Third Generation: The development of integrated circuits made computers even smaller and more affordable, leading to their widespread use in various industries and institutions. - Fourth Generation: The development of microprocessors led to the creation of personal computers, which revolutionized the way people work, communicate, and access information. - Fifth Generation: The use of artificial intelligence and advanced parallel processing has enabled computers to automate tasks, improve decision-making, and advance fields such as healthcare, finance, and transportation.

Ans. The key features of the fifth generation of computers are as follows: - Artificial Intelligence: Fifth-generation computers are designed to simulate human intelligence and perform tasks that require human-like understanding and decision-making. - Advanced Parallel Processing: These computers are capable of processing multiple tasks simultaneously, allowing for faster and more efficient operations. - Natural Language Processing: They can understand and respond to human language, enabling more intuitive and user-friendly interactions. - Knowledge Base: Fifth-generation computers have a vast knowledge base, allowing them to access and utilize extensive information for problem-solving and decision-making. - Robotics: They often incorporate robotics technology to physically interact with the environment and perform tasks.

Ans. Computers have evolved significantly over time from the first generation to the fifth generation. The key advancements include: - Size and Cost: Computers have become smaller, more affordable, and accessible to a wider range of users. - Processing Power: The processing power of computers has increased exponentially, allowing for complex calculations and faster data processing. - Reliability: The use of more reliable components such as transistors and integrated circuits has improved the overall reliability and performance of computers. - User Interface: User interfaces have become more intuitive and user-friendly, allowing for easier interaction with computers. - Advanced Capabilities: With the introduction of microprocessors and artificial intelligence, computers are now capable of performing complex tasks, learning from data, and making autonomous decisions.
