WAITING LINE MANAGEMENT
Definitions + Formulas

Arrival rate (λ): Average number of customers arriving per unit time.
λ = 1 / E(A)  E(A) = average interarrival time

Service rate (μ): Average number of customers served per unit time (per server).
μ = 1 / E(S)E(S) = average service time

Utilization (ρ): Fraction of system capacity being used. Must be < 1.
ρ = λ / (cμ)  c = number of servers

Coefficient of variation (CV): Measures variability.
Cₐ = σₐ / E(A), Cₛ = σₛ

Q1 Solid Modeling (Easy Explanation)

Solid modeling is a type of 3D CAD (Computer-Aided Design) used to create digital models of objects that have real mass and volume, not just outer surfaces.You can think of it like working with a solid block of clay or wood. When you cut or make a hole, the software understands that material is being removed and automatically creates the inner surfaces.In simple words, solid modeling helps create accurate and realistic 3D objects that behave like real-world

BDC MOTOR AND TEM UNIT 2

BLDC Motor (Brushless DC Motor):
A BLDC motor is an electric motor that operates without brushes and uses electronic commutation instead of a mechanical commutator; it works on the principle of interaction between a rotating magnetic field and permanent magnets, providing high efficiency, low maintenance, and long life.
Principle of BLDC Motor:
A BLDC motor works on the principle of electromagnetic interaction, where a current-carrying conductor placed in a magnetic field experiences a force; in this

Characteristics and Functionalities of Rootkits
1.Stealth and Persistence
Rootkits hide their presence from users and security software and remain active even after system reboots. 
2.Privilege Escalation
They gain administrator or root-level access, allowing full control over system operations. 
3.Kernel-Level Access
Some rootkits operate at the kernel level, giving deep control over the operating system and making detection difficult. 
4.Backdoor Functionality
They create hidden entry points
