BIOS initializes hardware at startup and allows access to CMOS settings. CMOS stores settings like time, date, and boot order and is powered by a battery. The POST tests hardware at startup and may display error codes for failed components. BIOS can be upgraded via flashing and CMOS restored via jumper to factory defaults.

Computer fans are cooling systems that help remove heat from computer components and keep them within safe temperature limits. Fans are located on the CPU and graphics cards to cool the processors directly, and case fans draw cooler outside air into the case and circulate it to dissipate heat from all interior components. Issues like loud fan noise can occur when components overheat, and adding additional case fans can help remove excess heat and reduce fan speeds.
Technical drawing is used to convert ideas and designs into physical forms by using detailed graphics. It has been used since the 18th century and is now often done using computer-aided design software. Technical drawings are made using tools like drafting tables, rulers, compasses, and specialized pencils and pens. They serve various purposes like construction, cutaway views, exploded views, and patents. Technical drawing methods include sketching, manual drafting using instruments, and computer-aided design. Key applications are architecture, engineering, and manufacturing.
