Embedded system. An embedded system is a specialized computer system —a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. [1][2] It is embedded as part of a complete device often including electrical or electronic hardware ...
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally ...
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other ...
Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [ 1 ][ 2 ]
Computer science is the study of computation, information, and automation. [1][2][3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software). [4][5][6] Algorithms and data structures are central to ...

Desktop computer. A desktop computer system. It has a monitor, keyboard, mouse, speakers, and a computer tower. The computer tower contains the motherboard and processor. A computer lab with desktop PCs with flat-panel monitors. A desktop computer (often abbreviated desktop[1]) is a personal computer designed for regular use at a stationary ...
The kernel is a computer program at the core of a computer 's operating system and generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [ 1 ] It is the portion of the operating system code that is always resident in memory [ 2 ] and ...
