 Introduction Of "C"- "C" is a simple structure , procedure oriented programming language and used to implement application programming as well as system programming. Note - There is no full form of "C" , it is implemented after language "B" that's why it is called "C".   WHY C? "C" is simple , small and fast. why not C++ , C# or Java , because "C" is the basis of all language. Unix , Linux , windows are written in "C". Embedded and mobail devices use "C". Gaming framework are written in c eg-directx. "C" offers better interaction with hardware. "C" is important to build programming skills. "C" covers basic feature of all programming language. "C" is a parent language for many others language like java , python , oracle etc. Now a days "C" also included in school and core branches in Engg. History Of "C"/"C++" In 1996 martin...

Basic Introduction Of Programming Language: Definition Of Computer : -Computer Is an electronic device,which takes input user, process them and generate output accordingly requirements. Difference Between Computer And Calculator; -using calculator we can perform only arithmetic operation and using computer we can perform arithmetic operation as well as logical operations. Logical Operations Like: (20>10) T/F O.S :-(Operating System)      OS is a system software.it is a interface between user and computer hardware and computer HW does every work using OS, first of all OS perform booting process(means check all connected H/W)and provide one interface (Eg.Dos Prompt/Desktop).OS Opeartes Application SW(word,excel,IE,Windows Media Player)Software System Software : Which is used to operate any hardware(system) Application Software ;Which is developed as per customer requirement. EX: Banking S/W, Gaming , IRCTC S/W , Mobile App Etc. FUNCTION OF OS Process Management Memory M...
