Difference Between USART and UART
In this post, we will understand the difference between USART and UART modes −USART (Universal Synchronous/Asynchronous Receiver/Transmitter)The half-duplex mode is used.The speed of USART is more in comparison to UART.It uses data signals as well as clock to work.The data is transmitted in the format of blocks.It can work similar to UART.It is more complex in comparison to UART.The receiver doesn’t require to know the baud-pace of the transmitter.This is because it gets information by the master and the clock signal.The data is transmitted at a definite (specific) rate.UART (Universal Asynchronous Receiver/Transmitter)It uses full-duplex mode.Its speed is less in comparison ...

In this post, we will understand the difference between internal and external fragmentation −Internal FragmentationThe difference between the memory allocated and the space required is known as internal fragmentation.In this fragmentation, fixed-sized memory blocks are used to process data.This process occurs when a method or process is larger than the required memory.The method used in internal fragmentation is ‘best-fit’ block.It occurs when the memory is divided into fixed sized partitions.External FragmentationThe unused spaces that is formed between fragments of non-contiguous memory, which are too small to help with a new process, is known as external fragmentation.It uses variable-sized memory blocks ...
Read MoreDifference Between Linker and Loader
In this post, we will understand the difference between a linker and a loader −LinkerThe main function of the linker is to generate executable files.The linker takes the input as the object code which would be generated by a compiler/assembler.The process of linking can be understood as a method to combine different snippets of code in order to obtain executable code.There are two types of linkers available: Linkage Editor and Dynamic Linker.Linker also helps combine all the object modules.Linker is responsible to arrange the objects in the program’s address space.LoaderThe main function of a loader is to load executable files ...
