Compute units commonly used on computers

Capacity units

Speed Unit

　　The unit used in this network is Mbps is Mbits per second, that is, how much Mbit per second.

PC Architecture and Interface devices

　　The most important thing on the motherboard is the chipset! And the chipset is usually divided into two bridges to control the communication of the components, respectively:

(1) North Bridge: Responsible for the link faster CPU, memory and graphics and other components;

(2) South Bridge: Responsible for the connection speed of the peripheral interface, including hard disk, USB, network card and so on.

Cpu

　　At the top of the central part, that's the CPU socket. The CPU is responsible for a large number of operations, so the CPU is usually a component with quite high calorific value. So if you've ever opened a motherboard, you should see that the CPU usually installs a fan to actively dissipate it.

Due to the x86 architecture of the CPU in the Intel Pentium Series (1993) after the non-uniform foot design, in order to be different kinds of CPU specification level, so there are i386,i586,i686 and other nouns appear. Basically, the CPU of the Intel Pentium MMX and AMD K6 years is called the i586 level, and the 32-bit CPUs after the Intel Celeron and AMD Athlon (K7) years are called i686 levels. The current 64-bit CPU is collectively referred to as the x86_64 level.

Memory

　RAM, ROM

Graphics

　　The memory capacity of the graphics card will affect the final screen resolution and color depth.

Hard disk

　　The hard drive is divided into 3.5-inch and 2.5-inch sizes based on desktop and notebook computers.

In the case of the hard disk is actually a lot of circular disk, mechanical arm, head and spindle motor composed of the entire interior as shown:
