Q 1. Explain K-map with example.
Karnaugh Map (K-Map) is a graphical method used to simplify Boolean expressions and logical functions. It is mainly used in digital electronics and computer science to reduce a complex Boolean expression into a simpler form. A K-Map represents the values of a Boolean function in the form of a table or cells. By grouping the adjacent cells containing 1 or 0, unnecessary variables can be eliminated and a simple Boolean expression can be obtained.
K-Map helps in designing
Q.1. Explain base load and peak load plan.
Ans:- Base Load:- 1)Base load is the minimum continuous load demanded by consumers throughout the day.2)It remains almost constant for a large part of the 24-hour period.3)Base-load power plants operate continuously and supply the basic electricity demand.4)Thermal, nuclear and large hydroelectric power plants are commonly used for base-load operation.5)Base-load plants generally have high efficiency and low operating cost but may have higher initial cost.

VM: address space, divided into fixed size pages (4KB standard); physical mem serves as a cache for these pages. A page table (which is per process) maps virtual pages to physical pages, ort marks as invalid/unmapped Address translation: VA = [ VPN | VPO], MMU looks up VPN in the page table to get a page table entry. if valid it resolves to the PPN = [ PPN | VPO ] Page Fault: Occurs when a ptr valid bit is 0. triggers OS fault handler, picks victim physical page, |
A model is a simplified representation of a real-world system developed to understand, analyze, or predict its behavior. A model contains only the important characteristics of the actual system and ignores unnecessary details.
Models can be classified into several types. A physical model represents a system physically, such as a prototype of a machine. A mathematical model represents the system using equations,

UNIT I: Fundamentals of Object-Oriented Programming & Java Basics
* Basic Concepts of OOP: The fundamental pillars are Classes, Objects, Encapsulation (hiding data), Inheritance (reusability), Polymorphism (one interface, multiple methods), and Abstraction.
* Java Evolution & Features: Java is distinct from C/C++ because it is platform-independent (Write Once, Run Anywhere), robust, secure, and uses both a compiler and an interpreter. It does not support...
a) Define Machine Learning: Machine Learning is a subset of Al where a system learns patterns from data and makes decisions or predictions without being explicitly programmed for every task.
b) What is over-fitting in Machine Learning?: Over-fitting is when a model learns the training data too well, including noise. It performs very well on training data but poorly on new unseen data
c) What is underfitting?: Underfitting is when a model is too simple to capture the underlying pattern in the data.
Cancer is a serious disease characterized by the uncontrolled growth and spread of abnormal cells in the body. It can affect any part of the body and is often named according to the organ or tissue where it originates, such as breast cancer or lung cancer.
Causes (Etiology)
Genetic mutations in cells
Hereditary factors (family history)
Viral and bacterial infections
Physical agents such as radiation and UV rays
Chemical carcinogens and toxic substances
