A computer system consists of hardware components that have been carefully chosen so that they work well together and software components or programs that run in the computer. The main software component is itself an operating system (OS) that manages and provides services to other programs that can be run in the computer.
A computer is a programmable device for processing, storing, and displaying information. Learn more in this article about modern digital electronic computers and their design, constituent parts, and applications as well as about the history of computing.
Guess what? The size of the computer system has reduced drastically, but it is more powerful and functional than the big machines of previous generations. This article discusses the components of a computer system and how its parts work together to ensure we keep breaking limits in this digital age. Let’s get started. What is a Computer System?
Computer systems come in a wide array of types of computers, each designed to serve specific needs and applications. They vary in size, power, complexity, and cost, depending on their intended use.
A typical digital computer system has four basic functional elements: (1) input-output equipment, (2) main memory, (3) control unit, and (4) arithmetic-logic unit. Any of a number of devices is used to enter data and program instructions into a computer and to gain access to the results of the processing operation.
How come they are so phenomenally useful? And how exactly do they work? Let's take a closer look!

Examples of Computer Architecture. What Is Computer Architecture? Computer architecture refers to the end-to-end structure of a computer system that determines how its components interact with each other in helping to execute the machine’s purpose (i.e., processing data), often avoiding any reference to the actual technical implementation.
Computer system - A combination of hardware and software that can be programmed to perform a variety of tasks. Hardware - The physical parts of a computer system.
Every computer system, for example, requires an operating system. The term “computer system” is often used interchangeably with the term “computer,” but they do not actually mean the same thing. A computer system can be as simple as a single device, or it can be an entire network of devices working together.
A computer system is a basic, complete and functional hardware and software setup with everything needed to implement computing performance. That’s the basic working definition of the computer system as we know it, but it has gone through a lot of formal changes over the past few decades.
