What is the difference between a kernel and an operating system?
Operating SystemAn operating system (OS) is a collection of software that manages computer hardware resources and acts as an interface between user and hardware of the computer.

The OS is a crucial component of the system software in a computer system.KernelKernel is the core part of operating system and responsible for all major activities of this operating system. Kernel consists of various modules and it interacts directly with the low level hardware. It also provides the required abstraction to hide low level hardware details to system or application programs. An operating system is ...
Read MoreWindows Anonymous Pipe
Windows anonymous pipes are actually Ordinary pipes, and they behave similarly to their UNIX counterparts: they are unidirectional and employ parent-child relationships between the communicating processes. In addition, reading and writing to the pipe can be accomplished with the ordinary ReadFile() and WriteFile() functions. The Windows API use CreatePipe() function for creating pipes, which is passed four parameters. The parameters provide separate handles forreading andwriting to the pipeAn instance of the STARTUPINFO structure, used to specify that the child process is to inherit the handles of the pipe.the size (in Bytes) of the pipe may be specified.Windows requires the programmer ...

Change in one layer specification does not affect the rest of the layers. Each of ...
Read MoreStorage Device Hierarchy
Computer storage has components that store computer data. The different storage types in the storage hierarchy are as follows: Primary Storage This is also known as the main memory and is the memory directly accessible by the CPU. All the instructions are executed in the main memory by CPU and the data required by these instructions is also stored in main memory. Main memory primarily consists of the RAM which is volatile in nature. It is also quite small compared to secondary memory and expensive as well. Secondary Storage Secondary or external storage is not directly accessible by the ...
Read MoreWhat is the difference between time.clock() and time.time()?

For Windows, the epoch is January 1, 1601.time.time() is used for benchmarking on Windows. time.time() behaves the same on both UNIX and Windows but time.clock() has different meanings.On UNIX, time.clock returns the current processor time expressed in seconds, i.e., the CPU time it takes to execute the current thread so far. While on Windows, it returns the wall-clock time expressed in seconds elapsed since the first call to this function, based on the Win32 function ...
