CETPA INFOTECH PVT LTD is one of the IT education and training service provider brands of India that is preferably working in 3 most important domains. It includes IT Training services, software and embedded product development and consulting services.

1. EMBEDDED SYSTEM
An embedded system consists of hardware and software. When
chips are built into systems and software is loaded on that for a
particular functionality, it becomes an embedded system.
Embedded systems are the micro-processor/micro-controller
based computing/control systems which are designed to
perform a specific or a set of tasks.

2. Microprocessor Based System
General purpose systems Embedded systems
• General purpose systems i.e. • Designed to perform a
a single system can perform specific task. i.e. a limited
variety of operations. operations.
• System designer decides the • Features of the system are
features and their strength. constrained.
•Bulky and costly. • Comparatively optimized.
e.g. Personal computers, e.g. Calculators, Robots,
Laptops etc. Automation control etc.
