Microcontroller Addressing Modes and Assembly Programming Concepts
1. Define Addressing Mode
Addressing Mode Definition
An addressing mode is the method a microcontroller uses to specify the location of the data (operand) required by an instruction. It determines how and from where the CPU fetches data—whether from a register, a memory address, an immediate constant, or through pointer-based access.
Why Different Addressing Modes Are Used
Different addressing modes are provided to achieve:
Programming Flexibility
Allows data to be accessed in multiple ways—direct,
Operating System Fundamentals: Structure, Processes, and File Systems
W1.1 Operating Systems Fundamentals
W1.1.1 OS Introduction
W1.1.2 Types of Operating Systems
Examples of Operating Systems include: Android, Linux, FreeBSD, MacOS, MS-DOS, Windows, uCOS, VxWorks. These systems are suited to small, medium, or large systems, exhibiting different characteristics regarding:
- Responsiveness
- Efficiency
- Flexibility
- Security
- Reliability
W1.1.2 Different Kinds of OS
Operating systems are categorized based on their usage:
- Single-user systems: Execute one program at a time for one user.
Regression, Regularization and Time Series Concepts for ML
1. Univariate linear regression assumptions
- Linearity: The relationship between X and Y is linear.
- Independence: The residuals (errors) are independent of each other.
- Homoscedasticity: The variance of residuals is constant across all levels of X.
- Normality of errors: The residuals follow a normal distribution.
These assumptions are important because they ensure the reliability and accuracy of the linear regression model. If the relationship between X and Y is not truly linear, the model won’t capture

Bell’s Palsy Etiology
Idiopathic; commonly associated with HSV-1, VZV. Autoimmune inflammation or ischemia is suspected. Sporadic outbreaks are reported.
Clinical Features

- Rapid onset facial weakness within 48 hours.
- Loss of forehead wrinkling and eye closure.
- Impaired taste (anterior 2/3 of the tongue).
- Hyperacusis (stapedius paralysis).

Design Thinking: Human-Centered Innovation Strategies
What is Design Thinking?
Design Thinking is a human-centered innovation methodology used to solve complex problems through a creative, structured, and iterative process. It combines empathy, creativity, and rational thinking to develop solutions that are desirable for users, economically viable, and technologically feasible. Its importance lies in placing people at the center of innovation, rather than starting from technology or business constraints. In real innovation contexts, this approach helps

Volume and Surface Resistivity Testing
- Volume Resistivity: Measures the electrical resistance through the bulk of the material. It is the ratio of the potential gradient to the current density. It indicates how well a plastic insulates against leakage through its body.
- Surface Resistivity: Measures the resistance to leakage current along the surface of the insulating material. It is important for applications where surface contamination or moisture might create a conductive path.
- Testing: Usually performed
Sale of Goods Act 1930 — Price, Title, Transfer & Remedies
Here are the key concepts of Price, Conditions and Warranties, Transfer of Ownership, and Performance under the Sale of Goods Act, 1930.
Price (Sections 2(10), 9, 10)
The price is the monetary consideration for a contract of sale of goods. It is an essential element, since a transfer of goods for anything other than money is treated as barter, not a sale under the Act.
Ascertainment of Price (Section 9)
The price in a contract of sale may be fixed in any of the following ways:
| Mode of Fixing Price | Description |
|---|---|
| Fixed |
