CUDA Programming and Distributed Systems Fundamentals
CUDA and GPU Architecture
- Core Intuition: Data parallelism (same operations on many independent data points).
- GPU vs. CPU Cores: GPU cores are weaker individually but significantly more numerous (10,000+ in modern data centers).
- CPU Strengths: Sequential, branchy, and latency-bound workloads.
- CPU Silicon Investment: Branch predictors, caches, and deep pipelines.
- Latency Hiding: GPUs use thread oversubscription (warp switching).
- SIMT (Single Instruction, Multiple Threads): Allows per-thread program counters.

Diffusion and Osmosis: Principles of Passive Transport
Understanding Diffusion
Diffusion is the net movement of particles from an area of high concentration to an area of low concentration.
Key Characteristics of Diffusion
- It happens in liquids and gases.
- Particles move randomly all the time.
- It is a passive process.
- It does not need energy from the cell.
Diffusion in Biological Cells
Cell membranes are partially permeable. This means:
- Small molecules can pass.
- Large molecules cannot pass easily.
Diffusion happens across the membrane when there is a concentration

Dependent variable: Solubility of salt. - What is the dependent variable in throwing a stone with a stretched rubber band?
Answer: Distance travelled by the stone. - Write the fundamental units included in the unit of force.
Answer: Kilogram (kg), metre (m), and second (s). - Write a difference between fundamental unit and derived unit.
Answer: Fundamental units are independent, whereas derived units are formed from fundamental units. - Define controlled
The Economics of Higher Education: Costs and Benefits
1. Opportunity Cost of Higher Education
Opportunity cost is the value of the next best alternative forgone when making a choice. For students choosing higher education, this primarily means giving up the opportunity to enter full-time employment after completing A Levels. By attending university, students sacrifice several years of potential earnings while also paying tuition fees.
Extract 1 states that tuition fees could rise from £3,290 to a maximum of £9,000 per year. Although many students take

Realism in International Relations
Realism is based on three basic ideas shared by all its versions:
- Statism: States are the main players in world politics, not companies or individuals.
- Survival: Every state’s number one priority, always, is to survive.
- Self-help: There is no world police, so every state can only count on itself to stay safe.
Realists also maintain a pessimistic view of human nature, inspired by thinkers such as Thucydides, Machiavelli, and Hobbes.
Classical Realism argues that the problem

Limit Test for Sulphate
The Limit Test for Sulphate is used to detect and control the amount of Sulphate Impurity present in pharmaceutical substances. It is based on the formation of Barium Sulphate, which produces Turbidity/Opalescence. The turbidity of the Test Solution is compared with that of the Standard Solution.
Principle
Sulphate Ions react with Barium Chloride to form Barium Sulphate, a white insoluble precipitate.
Reaction: SO₄²⁻ + BaCl₂ → BaSO₄ ↓ + 2Cl⁻
The Turbidity produced
