Data Transmission and Networking
What is a packet?
A packet is a small unit of data sent across a network. Large files are divided into packets so they can be transmitted more efficiently.
What is a header?
A header is part of a packet. It contains the destination address and sequencing information so the packet reaches the correct device.
What is a payload?
A payload is the part of a packet that contains the actual data being sent.
What is a trailer?
A trailer is the last part of a packet. It contains

Digital Image Forensics
Raw Image File: An unprocessed image format from high-end cameras. It is proprietary and preserves the most complete sensor data. Demosaicing is the process of converting raw sensor data into a standard, viewable image format.
Metadata and File Structure:
- EXIF Data: Stores metadata like camera make, model, and serial number.
- File Header: The beginning portion of a file containing hexadecimal values (e.g., JPEG is FFD8).
- Bitmap Files: Store graphic information as a grid of individual
Financial Management Formulas and Ratio Analysis
Cost-Volume-Profit (CVP) Analysis
- Contribution Margin (CM) per Unit = Selling Price − Variable Cost per Unit
- CM Ratio = (Selling Price − Variable Cost) ÷ Selling Price × 100
- Break-Even Units (BEU) = Fixed Expenses ÷ CM per Unit
- Break-Even Sales (BES) = Fixed Expenses ÷ CM Ratio
- Additional Units (AU) = Target Profit ÷ CM per Unit
- Total Units (TU) = BEU + AU
- Total Sales = TU × Selling Price
- Margin of Safety = Actual Sales − BES
Net Present Value (NPV) Analysis
- NPV = Σ (Cn × PV Factor) − Initial
Combustion Stages and Working of SI and CI Engines
Stages of Combustion in SI and CI Engines
The P-θ Diagram plots pressure versus crank angle (θ) around Top Dead Center (TDC), illustrating the distinct stages of combustion for both engine types.
Combustion Stages in SI Engines
The Spark Ignition (SI) engine combustion process consists of three main stages:
- Ignition Lag (A-B): Also called ignition delay, this is the time between the spark occurring (A) and the start of flame propagation (B). No visible pressure rise occurs during this phase. It depends
Statistical Hypothesis Testing and Interpretation
Statistical Test Selection Matrix
- T-Test (1-Sample Mean): Testing a single group’s average (μ) against a single historical benchmark value.
- 1-Prop Z-Test (1-Sample Proportion): Testing a single group’s percentage or proportion (p) against a benchmark value.
- 2-Prop Z-Test (2 Independent Proportions): Comparing percentages or categorical success rates between two completely separate groups.
- 2-Sample T-Test (2 Independent Means): Comparing the average scores or numerical measurements between two separate
Pharmacology of Anti-Infective and Immunomodulatory Agents
1. Malaria: Life Cycle and Anti-Malarial Pharmacology
Life Cycle of the Malarial Parasite (Plasmodium)
- Infection: Female Anopheles mosquito injects sporozoites into the host during a blood meal.
- Liver Stage (Exo-erythrocytic): Sporozoites travel to the liver, invading hepatocytes to mature and multiply into merozoites. In P. vivax and P. ovale, some remain dormant as hypnozoites.
- Blood Stage (Erythrocytic): Merozoites are released into the bloodstream, invading erythrocytes (RBCs). They feed on hemoglobin,
