LO1    1.  Identifying Computer Hardware Components

        1.1. Introduction to computer hardware components

make the PC work. The most important part of the PC is the box that usually sits on top of your desk—the one that all the other parts connect to called the system unit. All of the processing and storage takes place in the system unit. All of the other parts of the PC—the printer, the keyboard, the monitor—connect to the system unit and are known A typical PC is more than one device, and you need all the parts (or at least most) to collectively as peripherals

LO2: Establish location for Hardware peripheral

       2.1  Determine suitable Environment:

       Environmental conditions

    Just like the environmental conditions affect us as humans, computer equipment can also be affected. In order install and maintain equipment to gain the maximum useful life, the environmental conditions need to be considered — factors such as temperature extremes, humidity, dust, electromagnetic interference (EMI), and so on.
