Each operating system usually consists of several features, among them memory, processor, device and file management but there are also networking features, security and I/O functions to be considered. Due to the similar nature of computer hardware then many operating systems will require most, if not all of those functions. However, from a technical perspective if we examine the interaction between the core computer hardware and the system applications then it is possible to narrow down those functions that can be deemed essential.
The core of the operating system, usually known as the kernel, provides the most basic level of control over the hardware. We can assume that the hardware would consist at the very least of a CPU, Memory and various Devices and the kernel would be responsible for managing each of these as required by any user interaction or application request.
