About Operating Systems

✴ An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command line or a graphical user interface (GUI).✴ ► This App has been prepared for the computer science graduates to help them understand the basic to advanced concepts related to Operating System.✦ 【Topics Covered in this App are Listed Below】 ⇢ Operating System - Overview ⇢ Types of Operating System ⇢ Services ⇢ Properties ⇢ Processes ⇢ Process Scheduling ⇢ Operating System Scheduling algorithms ⇢ Multi-Threading ⇢ Memory Management ⇢ Virtual Memory ⇢ I/O Hardware ⇢ I/O Softwares ⇢ File System ⇢ Security ⇢ Linux
