Core–Periphery Model
-Core: Wealthy, developed regions; advanced technology, strong infrastructure, high incomes. Example: New York City
-Semi-Periphery: Moderately developed; growing industry and economy. Examples: Brazil, Mexico
-Periphery: Less developed; limited industry and infrastructure. Examples: Ethiopia, Haiti
-Core dominates economy; semi-periphery develops; periphery depends on others.
Urban Growth Vocabulary
-Exurb: Residential area beyond suburbs; people commute long distances. Example:
Population = entire group being studied
Sample = subset of the population
Example
Population: all university students
Sample: 200 students surveyed
Parameter vs Statistic
Parameter → numerical value describing population
Statistic → numerical value from sample
Examples
p = true population proportion
p̂ (p-hat) = sample proportion
Sample proportion formula
p̂ = x / n
where
x = number of successes
n = sample size
Example

22❓ Q1. Explain evolution of the web from Web 1.0 2 Web 4.0.
🔹 Introduction: The World Wide Web hs evolved significantly since its creation. Initially, the web was used only 4 sharing basic information, but over time it hs become a powerful platform 4 communication, business, collaboration, & intelligent services. The development of web technologies is commonly divided into 4 stages: Web 1.0, Web 2.0, Web 3.0, & Web 4.0. Each stage improvements in technology, interactivity, user participation,
Core system problems persist: Variability, congestion, coordination, flow.
Production system layouts: Layouts depend on volume, variety, and material flow. And determine how work flows through the system between work centers.
Product line Layout:(flow lines)FAST, PREDICTABLE, INFLEXIBLE. Resources arranged in processing order, follows single fixed path, designed for mass production. e.g. automotive assembly & consumer electrics. Pros: large outputs, efficiency. CONS: long switchovers/
