Distributed System
SAD is a process for analyzing an organization's needs and designing new information systems to meet them.
Simple Definition:
A Distributed System is like a team of computers (or devices) working together over a network to achieve a common goal, but they look and feel like a single system to the user.
In Short:
A Distributed System is like a team of workers in different rooms of a building — each doing a part of the job, but to the customer, it feels like one smooth service.
Human-Friendly Explanation:
Imagine you order food from a food delivery app (like Zomato or Swiggy):
- One server shows the menu
- Another server checks your location
- Another one processes payment
- Another one manages delivery
All these parts work together, but they are running on different computers in different places. Still, to you, it feels like one single app — that’s a distributed system
