What is considered a peripheral on a computer system?

A peripheral on a computer system refers specifically to hardware devices that are not part of the core computer architecture but are essential for input, output, or storage purposes. Examples of peripherals include keyboards, mice, printers, scanners, and external storage devices. These components interact with the central processing unit (CPU) and often enhance the functionality of a computer, allowing users to perform additional tasks.

While software applications, operating systems, and network connections play critical roles in the overall functioning of a computer system, they do not fall under the category of peripherals. Software applications are programs that run on the operating system and perform specific tasks. The operating system itself is also crucial, as it manages hardware and software resources. Network connections facilitate communication and data transfer between devices, but they are not physical components that can be categorized as peripherals. Thus, the identification of peripherals as hardware devices accurately captures their role in computer systems.
