⭐ UNIT – 3 (Easy Notes + PDF References) Wireless LAN • MAC Problems • Hidden/Exposed Terminal • Near/Far • Infrastructure vs Ad-hoc • IEEE 802.11 • Mobile IP • Ad-hoc Routing

  ⭐ UNIT – 3 (Easy Notes + PDF References) Wireless LAN • MAC Problems • Hidden/Exposed Terminal • Near/Far • Infrastructure vs Ad-hoc • IEEE 802.11 • Mobile IP • Ad-hoc Routing I have rewritten everything in easy school-level English so you can understand quickly. 🔵 1. What is WLAN? (Wireless LAN) (Page 1 U-3 Wireless & mobile computing ) WLAN = Wireless Local Area Network. It allows devices to connect without cables using radio, infrared, or microwave signals. Why WLAN? ✔ No wires needed ✔ Quick installation ✔ Can attach to existing wired network ✔ Useful in disasters or old buildings where wiring is impossible 🔵 2. Design Goals of WLAN (Page 2–3 – Table shown in PDF U-3 Wireless & mobile computing ) ✔ Simple to use Users should easily connect. ✔ Low power use Mobile devices need long battery life. ✔ No license needed Using license-free bands reduces cost. ✔ Handle interference There is a lot of radio noise; WLAN must work even in interference. ...

UNIT–5 (Simplified & Easy Notes) Software Architecture Documentation

  UNIT–5 (Simplified & Easy Notes) Software Architecture Documentation ✅ What is Software Architecture Documentation? It explains how the software system is structured . Helps developers understand system components , modules , and design , without reading code. Works as a communication tool between architect, developer & stakeholder. ⭐ Goals of Documentation (Very Important) Knowledge Sharing Helps new developers understand the system quickly. Communication Architects share design ideas with developers. Analysis & Review Used to check if architecture meets requirements. ⭐ Two Ways to Create Architecture 1. Top-Down Approach Start from big design → break into smaller parts. Used when system requirements are clear. 2. Bottom-Up Approach Start from small components → combine to form system. Used when building systems step-by-step. ⭐ Principles of Sound Documentation (Super Important – Exam Repeated) Princ...

 Here's a breakdown of the Software Engineering Institute's (SEI) Capability Maturity Model Integration (CMMI) framework elements, particularly relevant to the Unified Process (UP) and other structured methodologies: Framework Elements: Life Cycle Phases: Inception: Focuses on establishing the project's vision, scope, business case, and feasibility. Elaboration: Defines the architecture, refines requirements, and plans the remaining project. Mitigates high-risk elements. Construction: Iteratively develops and integrates the bulk of the software, building working versions. Transition: Deploys the software to the user community and ensures operational readiness. (Note: Your request mentioned "training phase" which often aligns with Transition activities.) Artifacts of the Process: The Artifact Sets (Categories): Management Artifacts: Pertain to project planning, tracking, and control (e.g., business case, project plan, risk list). Engineering Artifacts...
