Hi, guys, today I am going to give the basic introduction on IOT(Internet of things). IOT(Internet of things) is nothing but it is connected things or connected device. In IOT(Internet of things) environment objects, device,  people, buildings, plant all are embedded with a sensor, software, electronics and internet all are exchange the data between them compute them self without the human to human or human to computer interaction. The internet of things allows the objects  to be sensed and controlled by remotely across networked environment creating opportunities for direct integration between the physical world and computer-based systems, and resulting in improved monitor control efficiency accuracy economic and management benefit. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.In future iot device are basic need for people .for example your phone, smart watch, smart band, smart tags etc now days IOT are used in smart city ,smart home(home aut

Answer: Definition means where a variable or function is defined in reality and actual memory is allocated for variable or function. Declaration means just giving a reference of a variable and function. 3.What is interrupt?  Answer:  Interrupts (also known as traps or exceptions in some processors) are a technique of diverting the processor from the execution of the current program so that it may deal with some event that has occurred. Such an event may be an error from a peripheral, or simply that an I/O device has finished the last task it was given and is now ready for another. An interrupt is generated in your computer every time you type a key or move the mous

Answer: As systems got more complex the link between cause and symptom became less obvious. This meant that electronic systems had to have some level of self diagnosis and to communicate to the outside world. Initially many systems used their own protocols which meant that garages had to have a large number of tools – even to diagnose a single vehicle. 22.What is meant by verification and validation?? Answer: Verification and Validation (V&V) is the process of checking that a software system meets specifications and that it fulfills its intended purpose. It is normally part of the software testing process of a project. According to the Capability Maturity Model (CMMI-

Automotive Interview Questions and CAN interview questions and important C programming interview Questions are asked in Automotive interviews.This are the very important questions for automotive interviews.  1. What is CAN ?  Answer: 1. CAN is a multi-master broadcast serial bus standard for connecting electronic control unit (ECU).  2. Controller–area network (CAN or CAN-bus) is a vehicle bus standard designed to allow micro controllers a devices to communicate with each other within a vehicle without a host computer. 3. CAN is a message-based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment.  4. The Controller Area Network (CAN) bus is a serial asynchronous bus used in instrumentation applications for industries such as automobiles. 2. CAN frame works? Answer: CAN Frame SOF – 1 Dominant Arbitration Field – 11 bit Identifier, 1 bit RTR (or) 11 bit, 1SRR, 1IDE
