What are the accessories for computers?

The circled part, on the left is PCI, which is a bus standard interface that connects the computer motherboard and external devices, mainly reserved for some advanced devices, which is called forward compatibility in computer hardware design, for example, many motherboards integrate graphics cards, but also support the installation of one or more independent graphics cards, and the independent graphics cards are inserted in these slots; The circled one on the right with a golden heat sink is the North Bridge. The black chip without a heatsink under the PCI interface should be the South Bridge.

The first floor is perfect, but there are some mistakes that need to be corrected.

1. The brown single slot is the AGP slot, which is used to insert the old graphics card of the previous years, and the white three-strip is the PCI slot, which is used to plug in the sound card, cat, and other expansion devices.

3. The one with the golden heat sink is the Northbridge chip, which is responsible for the information exchange of CPU memory and graphics card.

4. **The upper left corner of the green quad is the South Bridge chip, which is responsible for various expansion slots and interfaces.

According to your **, from left to right, they are AGP, PCI, and North Bridge.

AGP: You can insert an external network card, sound card, detection card, etc.

PCI: You can insert a graphics card.

Northbridge: A bridge between CPU and memory information exchange.

The south bridge is underneath the AGP, the green one on one side and the black one in the middle!

If you want to know the detailed role, you can go down and introduce it in more detail.

It's AMD's CPU, you're drawing 1 PCI network card, 2 for the sound card, 3 for the discrete graphics card, 3 North Bridge, which is used to process high-speed signals, and the identification is complete.

If you insist on understanding it this way, the graphics card, I would like to compare it to the limbs, because the brain calculates whether the things can appear quickly need the limbs to embody, and the motherboard is the body. The brain and limbs need to be placed on a sound body.

It's an old computer, right? It should be the old p4. The places where you frame are: PCI, AGP, Northbridge.

DIY A computer needs to buy accessories such as CPU, motherboard, memory, hard disk, power supply, heat sink, graphics card, chassis, fan, heat sink silicone, if there is no monitor and other peripherals, you also need to buy.
