Evolution of computer systems. Computers are programmable electronic devices that can process data. To comprehend what a computer system is, it's important to analyze the history and evolution of computer system development over the years. Early models. The history of computer systems goes way back to Charles Babbage's differential machines.
The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster.
Computer Systems: Early Models To look at the history of a computing system, you have to go all the way back to Charles Babbage’s differential machine. This computer, (which never actually got fully built), predated and prefigured the mainframes and large-scale computers of the early 20th century the Von Neumann machine and its ilk, as ...
The system software is also designed and developed by the computer manufacturer to communicate with specific hardware components connected to the computer system. For example when we connect a new device to the system , we need to first install the device driver to operate the device such as camera , printer , scanner and other such devices .
The most common type of computer system is the desktop computer, which is a personal computer that sits on a desk or table and can be used by one person at a time.
