HP stands for High Point. HVAC, Building, and Structural. 3. These are the three main divisions of an HP office building. The company that makes the majority of your PC components knows a thing or two about heating, cooling, and ventilation, so it's no surprise they also offer up office furniture that integrates well with these systems. Your HP includes multiple microprocessors that control different functions of the computer, including where it gets its power from and how it controls lights, fans, and air flow within the case. Each component has its own processor and storage space, which are integrated into one system by the motherboard. It's important to understand that while each part of the HP may have its own controller, the final decision on what actions will be taken by each unit is made by the central processing unit (CPU). The CPU is the brain of the HP. It receives instructions from the keyboard and display and uses them to process data and tell the other parts of the computer what to do. The other major component responsible for communication between the various parts of the HP is called a bus. Buses are simply groups of wires that connect one component to another and allow them to communicate with each other.
