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/

4. W tekście Hanny Gadomskiej uważność oznacza świadome skupienie się na chwili obecnej i przeżywanie tego, co dzieje się tu i teraz. Dzięki temu człowiek może odczuwać wolniejsze tempo upływu czasu. Natomiast
--------------- LECTURE 4: ------------------ INSPECTION: Experts evaluate interface without involving users. Goal: Identify usability problems early in design. Advantages: Cheap, fast, early design feedback. Disadvantages: Depends on expert judgment, may miss real user issues. ----------- TYPES OF INSPECTION METHODS: 1.) Heuristic Evaluation, 2.) Cognitive Walkthrough, 3.) Pluralistic Walkthrough, 4.) Guidelines Review, 5.) Consistency Inspection. ----------- HEURISTIC EVALUATION: Developed
...f) Define (i) Diffusion current (ii) Drift current & (iii) Barrier potential in a pn junction.
Ans:
1. Diffusion Current: Due to the concentration gradient,
majority carriers move across the junction (holes from p-side to n-side and electrons from n-side to p-side). This motion constitutes the diffusion current.
2. Drift Current: The electric field in the depletion region
causes minority carriers to move across the junction (holes from n-side to p-side and electrons from p-side to n-side). This
Rigid tubing → stationary, straight runs
Flexible hose → movement / vibration
Examples: fuel, oil, hydraulic, oxygen, instrument lines.
Tubing vs Hose
Tubing → OD measurement
Hose → ID measurement
Size units → 1/16 inch
Examples:
#6 = 6/16 = 3/8"
#8 = 8/16 = 1/2"
Aluminum
low/medium pressure
~1000–1500 psi
Steel (CRES)
high pressure
3000+ psi
Titanium
stronger
lighter
❌ Never used in oxygen systems
→ oxygen reaction / combustion risk
Interaction Design (IxD): Designing interactive products to support the way people communicate and interact in their everyday and working lives. Winograd → “Designing spaces for human communication and interaction. Thackara → Focuses on the why and how of daily interactions. Saffer → “Art of facilitating interactions between humans through products and services.” Key idea: It’s about creating good user experiences, not just working systems. -------- Goal of interaction design: Reduce...
