A disassembly and assembly system unit refers to the process of taking apart and putting together the components of a computer system, such as the CPU (Central Processing Unit), motherboard, RAM (Random Access Memory), storage drives, power supply, and other peripherals. This process is often carried out for maintenance, repairs, upgrades, or customization of the computer hardware.

Disassembly involves carefully removing each component from the system, usually following specific instructions or guidelines provided by the manufacturer or knowledgeable sources. This may include unplugging cables, removing screws, and handling components with care to avoid damage.

Assembly, on the other hand, is the reverse process where the components are put back together to form a functional computer system. This typically involves reconnecting cables, securing screws, and ensuring that all components are properly seated and connected.

Performing disassembly and assembly of a computer system requires some technical knowledge and skill, as well as proper tools and precautions to avoid damaging the hardware. It's often done by experienced technicians or enthusiasts who are familiar with the intricacies of computer hardware.
