RTE calls are generated to communicate between software components. Different types of calls are generated for each interface.

• RTE calls are generated to exchange data and trigger actions between software components.

• The type of call generated for each interface depends on the communication protocol used.

• For example, in a RESTful API interface, HTTP requests like GET, POST, PUT, and DELETE are generated.

• In a messaging interface, calls like publish, subscribe, and request-respon...read more

Static analysis is a process of analyzing code without executing it. Different layers in development require different types of testing.

• Static analysis involves analyzing code without executing it

• Different layers in development require different types of testing

• For the presentation layer, testing can include checking for UI/UX issues, accessibility, and responsiveness

• For the business logic layer, testing can include checking for logical errors, data validation, and security v...read more

Type mismatch error occurs when incorrect data type is used in a program.

• Type mismatch error can occur when trying to assign a string to an integer variable.

• It can also happen when performing operations on incompatible data types, such as adding a string to a number.

• Type mismatch errors are common in programming languages like Java, C++, and Python.

Linux booting process involves several stages including BIOS, bootloader, kernel initialization, and user space initialization.

• The process starts with the BIOS (Basic Input/Output System) which initializes hardware components.

• The bootloader (GRUB or LILO) is then loaded which loads the kernel into memory.

• The kernel initializes drivers, mounts the root file system, and starts the init process.

• The init process then starts user space processes and services.

• The boot process can b...read more

CAN communication is not encrypted by default.

• CAN communication is not encrypted by default

• Encryption can be implemented on top of CAN communication for added security

• Examples of encrypted communication protocols include CAN FD with Secure Onboard Communication (SOC)

Time quanta refers to the smallest unit of time that a computer's operating system can allocate to a process.

• It is also known as a time slice or a quantum.

• It is used in multitasking operating systems to allocate CPU time to different processes.

• The length of a time quanta can vary depending on the operating system and its settings.

• If a process does not complete its task within its allocated time quanta, it is preempted and moved to the back of the queue.

• Examples of operating s...read more

DF memory stands for Delayed Feedback Memory.

• DF memory is a type of memory system used in digital signal processing.

• It is characterized by the presence of a feedback loop that introduces a delay in the memory access.

• DF memory is commonly used in applications such as echo cancellation and adaptive filters.

• It allows for the storage and retrieval of past data samples to perform calculations and adjustments.

• An example of DF memory is a tapped delay line, where the output of the m...read more
