Q1. ? is a Conceptual Model/Domain Model? Explain d step-by-step process 2 build it with a complete example frm POS system.
Answer:
Conceptual/Domain Model:
A Conceptual Model is a visual represent8on of d real-world problem domain showing d key concepts (classes), their attributes, & rel8onships without considering system implement8on.
Steps 2 build:
1. Identify Nouns & Verbs frm Requirements: Extract potential classes & oper8ons.
Example: POS system: Cus2mer, Sale, Product, Payment....
# what is code migration? explain the migration model
Code migration in distributed systems refers to the transfer of executable code from one machine (or process) to another to be executed remotely. It allows a system to move computations closer to the data or resources, improving performance, flexibility, and resource utilization. There are two main types of code migration:
1. Strong Migration: Moves the entire process, including code, data, and execution state, so execution can resume at the
Wastewater Tank → Pump → Photocatalytic Reactor (Coated Glass Plate with TiO₂ & Fe₂O₃ under Sunlight) → Purified Water Tank → Storage/Reuse
Correct Flow Sequence
Waste Water Tank
Contains contaminated water.
Pump
Pumps wastewater to the reactor.
Immobilized Photocatalytic Reactor
Glass plate coated with TiO₂ + Fe₂O₃.
Exposed to sunlight for photocatalytic degradation.
Purified Water Tank
Treated water is collected here.
Optional Second Tank / Recirculation Line
If treatment is incomplete,

#Characteristics of Distributed System (In Short)
1.Resource Sharing – Sharing of hardware, software, and data among multiple users.
2. Openness – Uses standard protocols and interfaces for interoperability.
3.Transparency – Hides the complexity of distribution from users (location, access, failure, etc.).
4.Scalability – Can expand in size and users without affecting performance.
5.Concurrency – Multiple users/processes can work at the same time.
6.Fault Tolerance – Continues working
Cross-Flow Microfiltration and Dead-End Microfiltration
Microfiltration is a membrane separation process used to remove suspended particles, bacteria, and other impurities from liquids using a membrane with very small pores (generally 0.1–10 µm). Two common modes of microfiltration are cross-flow microfiltration and dead-end microfiltration.
1. Cross-Flow Microfiltration
Cross-flow microfiltration is a membrane filtration process in which the feed solution flows parallel (tangential) to the membrane
