Life skills are the basic abilities we need to handle daily challenges and live a healthy, balanced life. They help us think clearly, manage our feelings, make good decisions, solve problems, and build good relationships with others. The World Health Organization (WHO) highlights 10 important life skills: 1.) Thinking skills: decision-making, problem-solving, creative thinking, critical thinking 2.) Social skills: communication, empathy, interpersonal skills 3.) Emotional skills: self-awareness, coping with emotions, coping with stress Life skills are the tools that make us stronger, wiser, and calmer in real life — at home, in school, at work, and in the community :) Life Skills for Everyday Success ~xRay Pixy https://youtu.be/AMsUfKRl4kw Video Chapters: Life Skills 00:00 Introduction 01:07 Life Skills 09:42 Real Life Challenge 13:44 Task For You #LifeSkills #SuccessTools #StressFreeLiving #algorithm #optimization #research #happylearning #algorithms #meta #optimizationtechniques #swa...

Software Engineering

 Software Engineering 

Software Engineering: Software Engineering (S.E.) is a profession dedicated to the designs, implementation, and modification of software. Applications of Software Engineering are: 
  1. Re-engineering of software
  2. Software Testing
  3. Software Maintainance 
  4. Software Analysis
  5. Software Design
  6. Software Implementation
The objective of software engineering is to produce good quality software, on time and within budget. To obtain this objective it is very important to focus on Software Quality and Software Development Process.
Software Characteristics are: 
  1. Reusability of the components.
  2. Softwares are not manufactured as hardware. 
  3. In the Software development process, there is no wear-out phase.
  4. Software is fixable.
Software Life Cycle Models: Software life cycle means the time period when a software product is conceived and when the software product is no longer available for use. The software Life cycle includes different phases:
  1. Requirement Phase
  2. Design Phase
  3. Implementation Phase
  4. Testing Phase
  5. Installation Phase
  6. Operation and Maintenance Phase
  7. Retirement Phase 
Software Requirement - > Software Design - > Software Implementation - > Software Testing - > Software Installation - > Software Maintenance - > Software Retirement. 

Software life cycle models in software engineering are often known as Software Development Life cycle (S.D.L.C). Different software life cycle models are:
  1. The Waterfall Model
  2. Increment Process Models
  3. Evolutionary Process Model
  4. Prototyping Model
  5. Spiral Model
  6. COCOMO Model - Constructive Cost Estimation Model
COCOMO Model: COCOMO (Constructive Cost Estimation Model) is a heuristic estimation technique proposed by Boehm. According to Bohem, there are 3 categories for software development based on development complexity: 
  1. Organic - Application. 
  2. Semidetached - Utility.
  3. Embedded - System Programs.
Software cost estimation should be done through 3 stages: Basic COCOMO, Intermediate COCOMO, and Complete COCOMO. COCOMO models are useful for project Time and Cost estimation.
