Operating systems were first developed in the late 1950s to manage tape storage. The present-day popular OS Windows first came to existence in 1985 when a GUI was created and paired with MS-DOS. An Operating System acts as a communication bridge (interface) between the user and computer hardware. The purpose of an operating system is to provide a… Read More »
Prerequisite – C language C Preprocessor is not a part of the compiler, but is a separate step in the compilation process. Preprocessors are programs that process our source code before compilation. C Preprocessor is just a text substitution tool that instructs compiler to do required pre-processing before actual compilation. All preprocessor commands begin with a hash symbol… Read More »
Operating System (OS) is an interface between a computer user and computer hardware, which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers. Types of Operating Systems : Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400,… Read More »
