Which Maharashtra scheme aims to improve nutrition among tribal children?
This state-level program tackles malnutrition in tribal and remote areas.
Sanjay Gandhi Niradhar Anudan Yojana' is for—
Offers monthly financial aid to the helpless in Maharashtra.
Which ancient city of Madhya Pradesh was the capital of King Ashoka during his viceroyalty?
Who was the first Chief Minister of Madhya Pradesh?
In networking, what is the purpose of a “subnet mask”?
A subnet mask identifies the network and host portions of an IP address. It allows efficient routing and management of IP address blocks. Subnetting improves security and performance of networks.
What does “overfitting” mean in machine learning?
Overfitting occurs when a model learns training data too well, including noise and outliers. It fails to generalize to new data. Techniques like cross-validation and regularization are used to prevent it.
What does “virtual memory” refer to?
Virtual memory allows a computer to compensate for shortages of physical memory by using disk space. This helps run larger applications by extending RAM virtually. It slows down performance compared to real RAM.
Which logic gate returns false only when all inputs are true?
NAND (Not AND) returns false only if all inputs are true. It is considered a universal gate because all logical operations can be built using only NAND gates. It’s essential in hardware design.
Which of the following is NOT a functional programming language?
Pascal is a procedural programming language and not designed for functional programming paradigms. In contrast, Haskell and Scala are purely or partly functional. Python supports functional features but isn’t a functional language by design.
Which computer architecture uses a single bus for instructions and data?
von Neumann architecture stores both data and program instructions in the same memory. This design is simple but suffers from the "von Neumann bottleneck." It's used in most general-purpose computers.
What is the full form of JSON?
JSON is a lightweight data interchange format based on JavaScript syntax. It's widely used in web APIs and data transmission. It is human-readable and easy to parse by machines.
17. In Python, what will print(0.1 + 0.2 == 0.3) output?
Due to floating-point precision errors, 0.1 + 0.2 results in a value slightly more than 0.3. Thus, the equality test returns False. This is a classic floating-point arithmetic caveat in computing.
Which scheduling algorithm is used in real-time operating systems?
Rate Monotonic Scheduling is a priority-based real-time algorithm where shorter cycles get higher priority. It ensures predictable task execution. It's commonly used in embedded and control systems.
In Big Data, what does the “4 Vs” stand for?
Big Data is defined by its high Volume (data size), Velocity (speed), Variety (types), and Veracity (uncertainty). These characteristics pose challenges for traditional data processing. The 4 Vs guide the design of scalable data systems.
What does the acronym “DNS” stand for in networking?
DNS translates human-readable domain names like example.com into IP addresses. It acts like a phonebook of the internet. Without DNS, users would need to remember complex IP numbers.
Which network topology uses a central controller to manage communication?
In a star topology, each device connects to a central hub or switch, which controls data transmission. This makes troubleshooting easier but increases dependence on the hub. Failure of the hub can disrupt the entire network.
In C++, what is the default access specifier for class members?
In C++, class members are private by default unless explicitly specified. This promotes data encapsulation and hides implementation details. Structs, in contrast, have public members by default.
Who was the Nawab of Awadh when it was annexed by the British?
The last Nawab of Awadh, Wajid Ali Shah, was exiled by the British in 1856.
What is the main function of the large intestine?
The large intestine absorbs water and salts from undigested food, forming solid waste (feces).
Which microorganism causes AIDS?
HIV (a virus) attacks the immune system, leading to AIDS.
Which organ in the human body filters waste from the blood?
Kidneys filter blood, removing urea and excess water as urine.
Habitat of an organism refers to:
It's the natural home of an organism.
Light-sensitive layer of the eye is:
The retina contains photoreceptor cells (rods and cones).
The pigment responsible for the green color of plants is:
Chlorophyll absorbs light for photosynthesis and reflects green.
Which organ helps detoxify harmful substances in the body?
The liver breaks down toxins and drugs in the bloodstream.
The malaria parasite is transmitted by:
Female Anopheles mosquitoes transmit Plasmodium during blood meals.
Which component is responsible for rendering graphics in a computer?
GPU (Graphics Processing Unit) handles all rendering tasks.
If x = 3, find the value of x² + 2x
Explanation: 3² + 2×3 = 9 + 6 = 15
