An easy trick to remember this is that the name Molex (five letters) is longer than the name Berg (four letters). Newer power supplies provide special 15-pin power connectors for SATA drives. You can power SATA HDDs with either, but not both. NOTE: If a computer cannot remember its time and date, replace the BIOS battery. Use a multimeter to test the DC output. Set the multimeter to read volts DC (20V DC on older, non-auto-ranging multimeters). Put the common lead on the black ground wire or directly on the chassis (metal frame).
Almost all parallel ports are 32 31 Days Before Your CompTIA A+ Exams bidirectional, although some early ones were not. Printer cords have a Centronics port on the printer side. It is a trapezoid shape, but it is rather large and has wire “ears” that fold into place securing it into the printer. The mini-Centronics connection is about the same shape and size as a parallel port side, but it has blades like a SATA header. Parallel ports transmit multiple bits at a time, usually 4 or 8. Because some data transmissions are in serial format and some in parallel, Universal Asynchronous Receiver/Transmitter (UART) processing uses buffers to switch between the two.
Heat, size, and weight are always limiting factors. It is critical to keep the vents unblocked and lint free. Some laptops use a heat pipe that directs heat away from the CPU toward fans. Without the fan, the air will flow only by convection, which the cases are not designed for. Look at the spinning fan and make sure it is pushing air through the heat sink and that the power-supply fan is blowing air out of the case. Make sure the vents from the heat pipe are unblocked. Also make sure cables are not resting alongside the blades, because if they are they will make a whining or lawnmower noise.
