Embedded C is a programming language used for developing software for embedded systems.

• It is a subset of the C programming language

• It is used for programming microcontrollers, sensors, and other embedded systems

• It has limited resources and memory, so code optimization is crucial

• It includes basic data types like int, char, and float, as well as enums and structs

• Examples of embedded systems include automotive systems, medical devices, and consumer electronics

Errors are mistakes in a program that prevent it from running correctly.

• Syntax errors: occur when code is not written correctly (e.g. missing semicolon)

• Logic errors: occur when code does not produce the expected output (e.g. incorrect formula)

• Runtime errors: occur during program execution (e.g. division by zero)

Exception handling in Java is a mechanism to handle runtime errors and prevent program crashes.

• Exceptions are objects that are thrown at runtime when an abnormal condition occurs.

• Try block is used to enclose the code that might throw an exception.

• Catch block is used to handle the exception that is thrown in the try block.

• Finally block is used to execute code regardless of whether an exception is thrown or not.

• Example: try { // code that might throw exception } catch (Exceptio...read more

Web applications are software programs that run on web servers and are accessed through web browsers.

• Web applications are accessed through a web browser

• They run on web servers

• They can be accessed from any device with an internet connection

• Examples include online banking systems, social media platforms, and e-commerce websites

Yes, CTC is acceptable for me.

• Yes, CTC is acceptable for me as long as it is within the range I am looking for.

• I am open to discussing the CTC offered and negotiating if needed.

• I value the overall compensation package, including benefits, in addition to the CTC.

• I have researched the market rates for similar positions to ensure the CTC is competitive.

Conditional loops in Java are used to execute a block of code repeatedly based on a condition.

• Use 'if' statement to execute a block of code only if a specified condition is true.

• Use 'while' loop to execute a block of code as long as a specified condition is true.

• Use 'for' loop to execute a block of code a specified number of times.

There are different types of memory, such as RAM, ROM, and cache memory.

• RAM (Random Access Memory) is volatile memory that stores data temporarily while the computer is on.

• ROM (Read-Only Memory) is non-volatile memory that stores firmware and cannot be easily modified.

• Cache memory is a small, high-speed memory that stores frequently accessed data for faster retrieval.
