Let's start with the important ones,
First, the north and south Bridges, these two chips mainly control the coordination between the various hardware work and input and output, without them all the rest of the chips can not work.
And then there's the cpu, which is plugged into the board. The core of the computer, the processing speed of the computer depends on him, he is fast, the computer is fast.
Then is the graphics card (some do not have, with several chips, including the graphics card chip, video memory chip), the computer's image processing speed, in other words, to play games on him, mainly responsible for image processing and output.
Memory, inserted in the computer board, is responsible for the transmission between the CPU and the hard disk, the CPU can not directly read the hard disk data, you need to put the hard disk data into the memory, you can read. The memory is large, you can run more programs at the same time, of course, but also subject to CPU constraints.
And then there's the sound card, which is a tiny chip that processes sound output.
Network card, integrated, the role of basic needless to say, all know.
This is the main chip.
