UNIT 1: Understanding Web Paradigms and Evolution

Paradigms in Web Development

Paradigm: A set of habits, customs, and beliefs that shape our understanding of the world. Paradigms provide models, representations, and interpretations that guide scientific communities in problem-solving and solution identification. Science progresses through and is influenced by evolving paradigms.

Understanding Wireless Application Protocol (WAP)

What is WAP?

Wireless Application Protocol (WAP) is a technical standard for accessing information over a mobile wireless network. It enables mobile devices, like early cell phones, to display internet content efficiently.

How WAP Works

WAP operates through a three-tier model:

  1. Client: The mobile device running a WAP browser.
  2. Gateway: Translates WAP requests into standard web requests and vice versa.
  3. Origin Server: The web server hosting the content.

Week 1, Session 1: Embedded Systems

What is an Embedded System?

  • Purpose-built system/application serving a specific purpose/application
  • Minimizes cost/size/energy consumption
  • Resource-constrained

Microcontroller Unit (MCU)

  • Single Chip
  • Processor + Memory + I/O
  • Application Specific
  • Low power consumption

e.g., digital thermometer, washing machine

Microprocessor Unit (MPU)

  • General purpose
  • Requires external components
  • High computational power
  • Versatile but power-consuming

e.g., laptops, servers, high-end drives

MCU vs

Levels of Inheritance

3-Level Hierarchy

Java supports multi-level inheritance, where a class inherits from another class that inherits from a base class. For example:

class Animal {  void eat() {         System.out.println("Eating...");     }} class Dog extends Animal { void bark() {         System.out.println("Barking...");     }}  class Labrador extends Dog { void color() {         System.out.println("Labrador is golden in color.");     }} public class Main {     public static

1 – Logical vs. Physical Address Space and Memory Allocation

Logical Address

A logical address, or virtual address, is generated by the CPU during program execution. It’s a reference point within the program’s address space and doesn’t correspond to a physical memory location.

Physical Address

A physical address specifies the actual location of data in memory. The Memory Management Unit (MMU) translates logical addresses to physical addresses before accessing data.

Drawbacks of Contiguous Memory Allocation

  • External
