Description

Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device having a frame.

The server is the core computer that serves each computer in the network system. It can provide the functions of the disk and printing services required by the network users, and also allows each client to share resources in the network environment with each other. The basic structure of the server is roughly the same as that of a general personal computer. It consists of a central processing unit (CPU), a memory, and an input/output (I/O) device, and is connected by a bus. It is connected internally, connected to the central processing unit and memory through the north bridge chip, and connected to the input/output device through the south bridge chip. The server has undergone three evolutions in terms of chassis architecture: from early tower chassis to rack servers that emphasize centralized performance to high-density computing.
