Previously we discussed the types of heat sinks, fans, and liquid cooling that are used to lower component and system temperatures. Now we will look at keeping your system cool through even the most difficult of tasks.
Power protection
Video - 00:09:00
Electrical power from our grid is imperfect. Sometimes it provides too little or too much power. We use tools such as surge suppressors and uninterruptible power supplies to protect our PCs.
Form factors
Video - 00:06:00
Motherboards, power supplies, and cases are surprisingly interchangeable due to industry standards called form factors. Techs should know common form factors and the benefits and challenges of each.
What is BIOS?
Video - 00:06:00
Basic Input/Output Services (BIOS) is code (firmware) built into every motherboard to give the CPU basic communication with the hardware attached to the motherboard. BIOS is a critical part of the PC and a good tech needs to understand its function.
RAM technology
Video - 00:10:00
Dynamic random access memory (DRAM) comes in a number of versions defined by the doubling of commands they process per clock cycle. It’s important for techs to recognize these technologies and the speed rating systems used.
What is a CPU?
Video - 00:15:00
