An example block diagram, showing the Microsoft Windows 2000 operating system architecture. A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1]
A process control block (PCB), also sometimes called a process descriptor, is a data structure used by a computer operating system to store all the information about a process. When a process is created (initialized or installed), the operating system creates a corresponding process control block, which specifies and tracks the process state (i ...

Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]
Most file systems use directories to convert file names to file numbers. To find the block number, the operating system uses an index (often implemented as a tree). [105] Separately, there is a free space map to track free blocks, commonly implemented as a bitmap. [105]
The Windows NT operating system family's architecture consists of two layers (user mode and kernel mode), with many different modules within both of these layers.. The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.
They became a necessity in complex systems design to "understand thoroughly from exterior design the operation of the present system and the relationship of each of the parts to the whole." [3] Many specific types of functional block diagrams have emerged. For example, the functional flow block diagram is a combination of the functional block ...
Additional diagram of macOS architecture (2017 update) The architecture of macOS describes the layers of the operating system that is the culmination of Apple Inc.'s decade-long research and development process to replace the classic Mac OS.
