Hello everyone, next we will learn the structure of the mainboard

2

00:00:04,800 --> 00:00:11,066

Before learning the architecture of the mainboard, we first need to understand the concept of

3

00:00:11,700 --> 00:00:16,000

The bus is the communication bridge between the various modules of the computer

4

00:00:16,800 --> 00:00:23,900

Without the bus, information cannot be transmitted between modules, and they cannot work normally.

5

00:00:25,000 --> 00:00:29,166

Common buses in computers are shown in the table below

6

00:00:29,500 --> 00:00:30,800

DMI bus

7

00:00:31,166 --> 00:00:36,100

The DMI bus is the bus connecting the CPU and the bridge in Intel

8

00:00:36,766 --> 00:00:38,066

LPC bus

9

00:00:38,200 --> 00:00:42,933

The LPC bus is a bus used to connect EC or IO

10

00:00:43,566 --> 00:00:50,366

One end of the LPC bus is connected to EC or IO, and the other end is connected to CPU or bridge

11

00:00:51,533 --> 00:00:56,666

The PCIE bus is used to connect some expanded high-speed devices on the computer,

12

00:00:56,900 --> 00:01:00,100

such as graphics cards, network cards, etc.

13

00:01:00,800 --> 00:01:02,800

Sound card bus

14

00:01:03,133 --> 00:01:07,666

The sound card bus is the bus used to connect the sound card

15

00:01:08,600 --> 00:01:12,966

The SPI bus is the bus used to connect the BIOS chip

16

00:01:13,366 --> 00:01:18,466

Of course, it is sometimes connected to other devices, such as TPM chips

17

00:01:19,300 --> 00:01:21,400

DP bus, EDP bus

18

00:01:21,766 --> 00:01:25,333

The DP bus is the bus used to connect the DP interface

19

00:01:25,766 --> 00:01:32,400

The EDP bus is a bus that uses more built-in display interfaces in notebooks.

20

00:01:32,933 --> 00:01:37,800

Both DP and EDP are used to transmit display signals

21

00:01:38,800 --> 00:01:40,400

SM bus and I2C bus

22

00:01:40,833 --> 00:01:44,600

They are system management bus

23

00:01:45,400 --> 00:01:46,466

SATA bus

24

00:01:46,800 --> 00:01:51,933

SATA bus is used to connect SATA hard disk or optical drive

25

00:01:52,666 --> 00:01:59,333

There are many buses not listed here, such as USB bus, PS2 bus, etc.

26

00:01:59,866 --> 00:02:05,066

We don't need to memorize these buses, but the notes must be done well

27

00:02:05,400 --> 00:02:09,566

Because if you remember now, it will be more difficult to remember

28

00:02:10,133 --> 00:02:13,800

And these buses will be used frequently in the future

29

00:02:14,066 --> 00:02:17,566

After using it a lot, I will naturally remember it
