Q-2)Explain Common Bus System in detail with diagram.
The common bus system is an architecture where a single bus is used for communication
between the various components of a computer like memory, registers, and the ALU.
This system minimizes the number
of pathways
required, thereby simplifying the design and saving space.
Components:
* Set of Registers (R1, R2, ...)
* ALU
* Control Unit
* Common Bus
* Memory Unit
Operation:
* Only one register can place its contents on the bus at a time....
Q1. What are different classification of robot.
A1.Classifications of Robots:
Q2. Derive forward kinematic equation
Devices attached to the robot’s wrist that interact with the environment.
Examples: grippers, welding torches, suction cups.
Function: Convert linear motion into rotary motion.
Working Principle: Uses a lead screw mechanism; when a screw rotates, the nut moves linearly, which in turn rotates the actuator.
Applications: Robotic arms, CNC machinery, automation setups.
Pros: Precise control, high torque.
Cons: Slower speeds, wear
Two masses m1 and m2 move in a uniform gravitational field g and interact via a potential energy U(r).
(a) Show that the Lagrangian can be decomposed as
L = L_cm + L_rel
(b) Write down the Lagrange equations for the CM coordinates X, Y, Z and describe the motion of the CM. Then write the Lagrange equations for the relative coordinates and show that the motion of r is the same as that of a particle of reduced mass μ, position r, and potential energy U(r).

BCD is a way to represent decimal numbers in binary form, where each decimal digit is represented by a fixed number of bits, usually four.
Benefits of BCD include:
Straightforward to convert between BCD and denary (base-10).
Less complex to encode and decode for programmers.
Easier for digital equipment to use BCD to display information.
Can represent monetary values exactly.
Applications of BCD:
Electronic displays
A: Profit is the reward earned by an entrepreneur for organizing and managing the
factors of production. Economists have given various theories to explain the origin and
nature of profit. Each theory highlights a di erent aspect of entrepreneurship. The six
major theories of profit are explained below:
1. Rent Theory of Profit – F.A. Walker
This theory compares profit to rent.
Just like landowners get rent for using more fertile land, entrepreneurs get profit
due to their superior ability.
Quasi Rent
1. Introduced by dr marshaal
2.refers to the additional income earned by factors other than land
3.whose supply is fixed in the short period
4. term quasi rent will be used in the present volume as income derived from machines and other appliances of production Mande by man
5. quasi rent is not related to any particular factor of production whatever revenue firm earns in the short run over and above it’s variable cost is called quasi rent

Criticism of the Theory:
1. Unrealistic
SECTION 6.1 - Data, Information, and Business Intelligence
Four Primary Traits of Data Value:
Accuracy – Correct and reliable.
Completeness – No missing values.
Consistency – Same data, same format across systems.
Timeliness – Up-to-date and available when needed.
Types of Data:
Transactional Data: Supports daily tasks (e.g., sales receipts).
Analytical Data: Supports managerial decisions (e.g., trends).
