Question : Direction: Read the following passage and answer the questions given after it. The science of climate change is more solid and widely agreed upon than you might think. But the scope of the topic, as well as rampant disinformation, can make it hard to separate fact from fiction. Here, we've done our best to present you with not only the most accurate scientific information but also an explanation of how we know it. Climate change is often cast as a prediction made by complicated computer models. But the scientific basis for climate change is much broader, and models are actually only one part of it (and, for what it's worth, they're surprisingly accurate).
For more than a century, scientists have understood the basic physics behind why greenhouse gases like carbon dioxide cause warming. These gases make up just a small fraction of the atmosphere but exert outsized control on Earth's climate by trapping some of the planet's heat before it escapes into space. This greenhouse effect is important: It's why a planet so far from the sun has liquid water and life! However, during the Industrial Revolution, people started burning coal and other fossil fuels to power factories, smelters and steam engines, which added more greenhouse gases to the atmosphere. Ever since human activities have been heating the planet.

Question : Which of the following is an advantage of using computer-based tools for planning?
Option 1: Increased subjectivity
Option 2: Limited data analysis capabilities
Option 3: Improved accuracy and efficiency
Option 4: Reduced reliance on technology
Correct Answer: Improved accuracy and efficiency
Solution : The correct answer is (c). Improved accuracy and efficiency
Computer-based tools offer several advantages that can enhance the planning process. One of the key benefits is improved accuracy and efficiency. These tools allow for faster data processing, calculations, and analysis, reducing the chances of human errors and improving the overall accuracy of the planning process.
Computer-based tools can automate repetitive tasks, perform complex calculations, and generate reports or visualizations with speed and precision. This enables planners to work more efficiently, freeing up time for more strategic thinking and decision-making.
Furthermore, these tools often provide features such as data validation, error checks, and real-time updates, helping to ensure the accuracy and integrity of the planning data. They can also facilitate collaboration and communication among planning team members, improving coordination and efficiency in the planning process.
Question : Sheela recalls using transistors as part of her computer. Which generation of computers used it?
Option 1: Third
Option 2: First
Option 3: Fourth
Option 4: Second
Correct Answer: Second
Solution : The correct option is Second.
The use of transistors in computers is associated with the Second Generation of computers. The Second Generation, which emerged in the late 1950s, and lasted through the 1960s, replaced vacuum tubes with transistors, resulting in smaller, faster, and more reliable computers.
Hello,
Unfortunately, you won't be eligible for the BCA program at Aliah University because the eligibility criteria for BCA is that the applicants are required to achieve a 10+2 score in each specialization (Arts, Commerce, Science) by a recognized body with an overall grade of 50.

Hope this helps,
Thank you
Question : Comprehension:
In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.
A robot is a mechanical or virtual artificial agent, usually an electromechanical machine that is (1)______ by a computer programme or electronic circuitry. In general, robots can be autonomous or semi-autonomous and are now used in different fields. They have replaced (2)_______ in performing repetitive and dangerous tasks which humans prefer not to do, or are unable to do because of size limitations, or which take place in extreme (3)________ such as outer space or the bottom of the sea. For instance, robots can now be used in industry, as in car manufacturing, or they can be used in homes to do the (4)_______. Some robots may respond to speech or even be medical operating tools. There are concerns about the increasing use of robots and their role in society. Robots are blamed for the rising (5)________ as they replace workers in increasing numbers of functions.
Select the most appropriate option to fill in the blank number 5.
Option 1: unemployment
Option 2: peace
Option 3: social issues
Option 4: corruption
Correct Answer: unemployment
Solution : The correct choice is the first option.
Robots are often associated with concerns about job displacement and the potential increase in unemployment rates as they replace humans in various functions across industries.
The concern about the increasing use of robots and their role in society revolves around the potential impact on employment, specifically in terms of job displacement and rising unemployment rates.
Therefore, the complete sentence would be: "Robots are blamed for the rising unemployment as they replace workers in increasing numbers of functions."
Question :
Under computerised accounting, software means
Option 1:
A logical sequence of actions to perform a task
Option 2: System software and application software
Option 3: The raw fact (as input) for any business application
Option 4: Computer, associated peripherals, and their network
Correct Answer: System software and application software
Solution : Under a computerized accounting system, software means system software and application software. Hence, the correct option is 2.
Question : Which of the following is not a computer language?
I. C++
II. Java
III. Linux
Option 1: Only I
Option 2: Only III
Option 3: II and III
Option 4: I and III
Correct Answer: Only III
Solution : The correct answer is only III.
A Unix-like computer operating system called Linux was built using the free and open-source software development and distribution model. All general-purpose operating systems have a smaller installed base than Linux.
Question : Who among the following introduced the world's first laptop computer in the market ?
Option 1: Hewlett - Packed
Option 2: Epson
Option 3: Laplink travelling software Inc
Option 4: Microsoft
Correct Answer: Epson
Solution : The correct answer is Epson.
Epson released the world's initial laptop computer to the market in 1981. It was known as the Epson HX-20 and weighed 3.5 pounds. For its day, the Epson HX-20 was a game changer. It was the first battery-powered transportable computer, with a built-in keyboard and monitor. It also contained a printer, which at the time was unusual for portable computers.
Question : Find the part of the given sentence that has an error in it. If there is no error, choose 'No Error'. Producing a different component was as simple such launching a new computer programme.
Option 1: No Error
Option 2: Producing a different component was
Option 3: As simple such launching
Option 4: A new computer programme
Correct Answer: As simple such launching
Solution : The error lies in the third option.
The correct sentence uses the phrase "as simple as" to compare the simplicity of producing a different component to launching a new computer programme. The original sentence had a grammatical error by including "such" inappropriately. The correct structure for making a comparison in this context is "as simple as".
Therefore, the correct sentence should be: "Producing a different component was as simple as launching a new computer programme."
Question : Which of the following devices is used in digital circuits so that information stored in large computer memories is not lost during a momentary electric power failure?
Option 1: Thermistor
Option 2: Diode
Option 3: Transmitter
Option 4: Capacitor
Correct Answer: Capacitor
Solution : The correct option is a Capacitor.
In digital circuits, a capacitor is used to prevent information loss during momentary power failures. It acts as a temporary energy storage device, storing charge and providing a brief power supply to maintain memory integrity. This helps preserve data in computer memories when there is a short disruption in power.
