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 computer storage industry manufactures tape, magnetic, and optical storage and retrieval devices for computer systems.
NAICS 334112 applies to Computer Storage Device Manufacturing.
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)
Yes, any computer will need a number of basic components to function, and a number of peripheral devices. Its basic components are a motherboard, processor and memory. A computer will also need a monitor, harddrive and keyboard to function properly. Peripheral devices for input include a keyboard, mouse, webcam, scanner or drawing pad. Output devices include a monitor or printer.
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.
A computer is made up of many components (parts). There are five main types of components: (1) microprocessors, (2) memory chips, (3) input devices, (4) storage devices, and (5) output devices. The microprocessor, also known as the central processing unit (CPU), does the actual computing. Memory chips hold data and processing instructions for use by the microprocessor. The computer receives data through input devices, such as a keyboard. Storage devices, which include disks and tapes, hold data and instructions for transfer to memory. Output devices, such as a television-like monitor, show results of the computer work. A computer is made up of many components (parts).
