ISR stands for Interrupt Service Routine. It is a function that is executed in response to an interrupt signal.

• ISR is a type of callback function that is used in embedded systems.

• It is used to handle hardware interrupts, such as button presses or sensor readings.

• ISR is executed asynchronously and takes priority over other tasks.

• It is important to keep ISR functions short and efficient to prevent delays in other system operations.

• Examples of ISR include handling interrupts fro...read more

Stateflow is a graphical tool used for modeling and simulating decision logic in complex systems.

• Stateflow is a part of MATLAB/Simulink software

• It allows for modeling of finite state machines and flow charts

• Stateflow can be used for designing control logic in automotive systems, aerospace, and industrial automation

• It provides a visual representation of system behavior and logic transitions

C programming is a powerful and efficient programming language used for system programming, embedded systems, and more.

• C programming is a procedural language with a rich set of built-in functions.

• It allows for low-level memory manipulation and direct access to hardware.

• C is widely used for developing operating systems, compilers, and other system software.

• Example: Writing a program to calculate the factorial of a number in C.

Primary key is a unique identifier for each record in a database table.

• Primary key ensures each record in a table is unique

• It can be a single column or a combination of columns

• Primary key values cannot be NULL

• Example: 'ID' column in a 'Users' table

Foreign key is a field in a database table that links to a primary key in another table.

• Foreign key ensures referential integrity between related tables

• It helps maintain relationships between tables

• Foreign key constraints can be used to enforce data integrity

A unique key is a field or combination of fields in a database table that uniquely identifies each record in the table.

• A unique key ensures that no two records in a table have the same values for the specified key fields.

• It can be a single field or a combination of multiple fields.

• Unique keys are used to enforce data integrity and prevent duplicate records.

• Examples: Primary key, Unique constraint
