"Soft test" computer hardware

experience the advantages of drawing web, computer Hardware This part of the knowledge of three pages (soft book). But a lot of content. For those who develop software, it is also very necessary to understand the hardware.

Summary by drawing. Computer hardware is composed of three parts CPU, memory, input and output. The refinement is as seen: The CPU can be decomposed into an arithmetic device. Controller and so on, there is a connection between the two. storage, memory, input and output is an indispensable device.

Take a look at the overall map. You can see a lot of connections (see the big picture).

The relationship between the controller, the operator, and the register group in the CPU, the Register group is divided into dedicated (fixed) and universal (can be artificially defined for its use). Registers in both the operator and controller are private registers. Exception: The cumulative register in an operator is generic .

The map helps us to connect the points of knowledge, and when we want to use them we can string together the knowledge points, but the details of the books are repeated.

The exam does not yield more than scores, but also the learning process of learning methods and absorbed knowledge.
