All of them would be classified under "hardware" although the other devices connected to the computer would be classified in the subcategory "peripherals".
Output devices (monitors, printers, speakers, etc.) are classed as hardware, which makes them physical components.
Ryan Wallas' Hardware
The physical aspects of a computer, often referred to as hardware, include components such as the central processing unit (CPU), memory (RAM), storage devices (HDD or SSD), motherboard, power supply unit, and peripheral devices like monitors, keyboards, and mice. These components work together to enable the computer to process data, run applications, and communicate with other devices. Additionally, the physical casing or chassis houses and protects these components while providing ports and connections for peripherals. Overall, the physical aspects are essential for the computer's functionality and performance.
Input devices are considered hardware components because they consist of physical components that facilitate the interaction between users and a computer system. They convert user actions, such as typing or clicking, into data that the computer can process. Examples include keyboards, mice, and scanners, all of which are tangible devices that require physical connections or wireless communication with the computer. As essential parts of a computer system, they enable the input of information necessary for software applications to function.
A network card, or network adapter as it is sometimes called, allows a computer to connect to a network of other computers. These devices will usually have both a physical layer and a data link layer. Ethernet devices will most often have an 8P8C socket where the network cable can be connected.

Upgrades infer that you upgrade the physical components of the computer,rather than any of the data inside it's storage devices.
"Computer equipment" is/are those physical devices/components that go into making a computer or peripherals that may be attached to a computer to make a "computer system" fit for purpose. The "computer equipment" would not normally include the software but a "computer system" would.
Click on 'Start' - Control Panel - Devices and Printers. That will show you all the devices connected to your computer.
Physical topology refers to the physical layout of devices and cables in a network. It defines how devices are connected to each other and how data flows between them. Common physical topologies include bus, star, ring, mesh, and hybrid.
The mouse,keyboard,scanner,stylus,fingerprint scanner etc with your computer is and input devices. All the devices which provide information to your computer or thing that they are connected to are the input devices.
The five components of a computer:input devices, output devices,system unit,storage devices,and communications devices.
