1. Explain the classification of Engineering Materials with suitable examples. Discuss the crystal structures of BCC, BCC, FCC and HCP.
#.Classification of Engineering Materials:
1.Metals and Alloys: Characterized by metallic bonding, good electrical/thermal conductivity, ductility, and strength.
.Examples of Metals: Iron (Fe), Copper (Cu), Aluminum (Al), Gold (Au).
.Examples of Alloys: Steel (Fe-C), Brass (Cu-Zn), Bronze (Cu-Sn), Duralumin (Al-Cu-Mg-Mn).
2.Ceramics: Inorganic, non-metallic solids,...
Thermodynamics is the branch of science that deals with energy (heat & work both) transfer and its effect
on the state or condition of the system.
Thermodynamics basically involves four laws (explained later) known as Zeroth, First, Second and Third
law of thermodynamics.
Zeroth law deals with thermal equilibrium and relates to the concept of equality of temperature.
First law relates to the conservation of energy and introduces the concept of internal energy.
Second law relates...

1. BARR BODY ⭐
Definition
* Barr body is the condensed, inactive X chromosome seen in the nucleus of female somatic cells.
* It is also called sex chromatin.
Formation
* In females: 46,XX → one X chromosome becomes inactive.
* The inactive X chromosome becomes highly condensed and forms the Barr body.
* X-inactivation occurs early in embryonic development.
Number of Barr bodies
Barr bodies = Number of X chromosomes − 1
Examples:
* Normal female 46,XX → 1 Barr body
* Normal male 46,XY → 0
*...
Q 4. Write Short Notes on the Following:
(b) Real-Time Operating System (RTOS): A Real-Time Operating System (RTOS) is an operating system that provides a response within a specified time limit. It is used in applications where timing is critical.
Types of RTOS
1. Hard Real-Time OS: The deadline must be met. Missing a deadline may lead to system failure.
2. Soft Real-Time OS: Occasional delays are acceptable, but performance may be affected.
Applications
1. Medical Equipment 2. Robotics 3. Air...
Q 1. What is an Operating System? Explain its major functions and different types.
An Operating System (OS) is system software that acts as an interface between the user and computer hardware. It manages the hardware and software resources of a computer and provides an environment for running application programs.
Examples: Windows, Linux, macOS, Android and Unix.
