1:CUP in each component equivalent to the human head is responsible for computing data and controlling other components

2: The memory is in each component where data is temporarily stored when data is lost when the computer shuts down or restarts but it is computationally fast because the CUP calls its data first. ( his capacity and processing speed directly determine how fast the computer transmits data )

3: The hard drive is the place where data is permanently stored in the computer. such as: Movies / documents / pictures and other information places / work on the computer,CPU, There is a large amount of data exchange between input and memory, so the access speed and capacity of the memory are also one of the main factors that affect the speed of the computer ( in Server optimization scenarios, the performance of a hard disk is an important factor in determining the performance of the site.the hard drive is also divided into: mechanical hdd SATA,SAS SSD ssd<-- electronic hard drive. In the hard disk are all static files.

4: In the operation and maintenance of the main focus on the server to focus on the above three

5: There is a part of the server is more important is the power of the general server with dual power supply with two pieces of power (cluster can not use dual power supply)

6: The BIOS chip is responsible for the individual parts self-test / set / Save all normal after the motherboard power is switched on to start the operating system

7: Program belongs to code file, static, data placed on disk (static)

8: The process is a running program, the process is running the system to put the program in memory execution. (dynamic) will be released after reboot
