9.1.1 시스템 설정의 의미

시스템이 처음 작동할 때, 어떤 형태로 시작하고, 특정 내용을 어떤 모양으로 표시하고, 여러 가지 기능 중에서 어떤 기능을 사용할 수 있도록 하고, 시작과 동시에 어떤 작업을 시작할 것인지 등 시스템의 여러 가지 작동 방식에 대해서 운영자가 사전에 정할 수 있다. 이렇게 시스템이 처음 시작할 때 해당 시스템의 여러 가지 항목에 대해서 정의하는 것을 시스템 설정이라고 한다.

This section describes the configuration of the network related environment:

■ Setting hostname

Hostname is the name given to the computer itself, which is the name that other computers will use to refer to the current computer when communicating with other computers on the network. The Raspberry Pi system is named “raspberrypi” by default at the time it is installed. If you want to change it, you can specify it as a different name when you set the booting item.

Raspberry Pi_Eng_09.7.1 Setting Overclock

Posted on July 25, 2017 by weomega

9.7 Setting Performance Items

Here you can set the environment for items that affect system performance:

■ Setting overclock

Overclock means to increase the processing speed of the CPU by increasing the clock speed of the CPU while leaving the CPU unchanged when fast CPU processing is required for special purpose. Increasing the CPU clock speed will increase the CPU processing speed, but it can overload the CPU, causing a lot of heat in the CPU, which can damage the stability of the CPU and shorten the lifetime of the CPU. Thus, limited use is recommended.
