I think that today's computers really have more than six components, although I guess this depends upon whether you are - in taxonomical language - a lumper or a splitter. For a start, I would not ignore the various data buses which create the connectivity between processor(s) and the memory chips, RAID arrays of SCISI/SATA drives, and lots of USB plugin sockets. Also, you will not get very far on your PC without an assortment of I/O devices to manage your mouse and keyboard and either a plugin or on-M/B graphics generator so you can see what you are doing (on the monitor or TV, depending), not to mention today's invaluable ethernet device so you can LAN and WAN and route away to your heart's content. Finally, do not forget the multi-voltage DC power supply, without which none of the aboce will even warm up let alone "glow" for you. I agree that simple is nice, and classification is always a boon to clearer understanding, but I don't think that your six components quite cover the ground, so to speak. Others may disagree, as is the way of the world!
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
The five components of a computer:input devices, output devices,system unit,storage devices,and communications devices.
system unit
The operating system (OS) manages hardware components, including the CPU, memory, storage, and peripheral devices. It acts as an intermediary between users and the hardware, facilitating resource allocation, process management, and device communication. By efficiently coordinating these components, the OS ensures smooth operation and optimal performance of the computer system.
The computer storage industry manufactures tape, magnetic, and optical storage and retrieval devices for computer systems.
The main circuit board in a computer is called the motherboard. It serves as the central hub that connects all components, including the CPU, memory, storage, and peripheral devices. The motherboard also provides the necessary circuitry for communication between these components, enabling the computer to function as a cohesive unit.

Computer storage devices are hardware components that store and retrieve data in a computer system. They function by saving data in a way that can be accessed quickly and efficiently by the computer's processor. This allows users to store files, programs, and other information for later use. Common types of storage devices include hard drives, solid-state drives, and USB flash drives.
A motherboard is the main circuit board in a computer that connects and allows communication between various components, including the CPU, RAM, storage devices, and peripheral devices. It houses the chipset, which manages data flow between these components, and provides slots and connectors for expansion cards and other hardware. Essentially, the motherboard serves as the backbone of a computer system, facilitating its overall operation and functionality.
Storage devices are the core function and fundamentals of computers. The purpose of the storage device is to store information. If storage devices are removed from the computer, storing the information retrievals wouldn't be possible.
Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. (Source: wikipedia)
