Disassemble a computer
Everyone has a computer, a smartphone or maybe a connected TV. All these objects were created on the same model, the same architecture. Without looking for the moment to enter the details of the functioning of a computer, this video proposes to disassemble one to show the different elements, real organs of a computer …
Video textual transcription
- Motherboard: a printed circuit board which gathers a set of ports making it possible to connect the various elements of the computer (processor, memory cards, graphics card, hard disks and other peripherals) and to ensure their connection through printed circuits of which the behavior is controlled by the BIOS, program contained in the read-only memory (ROM) and launched at startup to detect and configure all the connected elements.
- Processor: (or CPU, for Central Processing Unit) electronic computing device, responsible for executing the various instructions of a program. In doing so digital data is processed, manipulated and exchanged with the other components of the computer (random access memory (RAM), hard drives, other peripherals) via the motherboard. When the processor is built on a single integrated circuit, it is called a microprocessor.
- RAM: (Random Access Memory) is a printed circuit on a card that stores data and instructions used in a computer program. Unlike read-only memory (ROM), the contents of the RAM can be modified and thus provides a dynamic storage space for the processor.
- Peripheral: an electronic device connected to a computer, more precisely on one of the ports of the motherboard.
- Port: socket for connecting a device to a computer. The ports are placed on the motherboard that connects to other devices and the processor.
