What are the subsystems of a computer?

A computer can be divided into three broad categories or subsystem: the central processing unit (CPU), the main memory and the input/output subsystem.

How do you identify a subsystem?

A subsystem is a system that is an element of another system. It is “smaller” than the containing system, in that it provides only some of the functions that the larger system provides. It is wholly contained by the larger system; no subsystem can cross the boundary of its containing system.

What are the subsystems of an operating system?

Subsystems are a part of larger systems such as operating systems; multiple subsystems can be loaded in the operating system. It bridges the gap between the users and the computer hardware. Various types of OS include Microsoft Windows, Linux, UNIX, Symbian, Android and Apple Mac OS among others.

What is a subsystem in technology?

Definition(s): A major subdivision or component of an information system consisting of information, information technology, and personnel that performs one or more specific functions.

What is memory subsystem?

The memory subsystem is made up of hardware and software components. It is in main memory that programs and the data they use are stored while the programs are executing. Data are also stored on slower peripheral devices such as disks and magnetic tape; programs are stored here as well when they are not executing.

What is the function of the ALU subsystem in a computer?

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs.

Is software a subsystem?

A subsystem usually refers to hardware, but it may be used to describe software. However, “module,” “subroutine” and “component” are more typically used to describe parts of software.

What are subsystems in engineering?

[′səb‚sis·təm] (engineering) A major part of a system which itself has the characteristics of a system, usually consisting of several components.

What is subsystem and types of subsystem in Windows?

According to MSDN documentation: Environment subsystems are Windows NT processes that emulate different operating system environments. The Windows NT executive provides generic services that all environment subsystems can call to perform basic operating system functions.

What is the function of the memory subsystem in a computer?

All memory subsystem components are for automatically retrieving operands from and storing results in their associated memory modules. All memory subsystem components have an output data connection and an input data connection.

What does subsystem mean in computer?

A unit or device that is part of a larger system. For example, a disk subsystem is a part of a computer system. A bus is a part of the computer. A subsystem usually refers to hardware, but it may be used to describe software. However, “module,” “subroutine” and “component” are more typically used to describe parts of software.

What is a subsystem in a mainframe?

In general, for mainframes as with other platforms, a subsystem is hardware or software that is fairly independent of the controlling system but performs functions under the direction of the controlling system. For example, the I/O subsystem in a mainframe will handle input and output operations between the CPU and the peripheral devices.

What is the difference between a bus and a subsystem?

A bus is a part of the computer. A subsystem usually refers to hardware, but it may be used to describe software. However, “module,” “subroutine” and “component” are more typically used to describe parts of software.

What are the components of a computer system?

These systems include the hardware (computers, devices, etc.) and the software (operating system, word processors, web browser, etc.), as well as the human or mechanical owner of the system.
