In the DOS memory model, the HIGH Memory Area (HMA). is the _____ memory.
In DOS memory management, the high memory area (HMA) is the RAM area consisting of the first 65520 bytes above the one megabyte in an IBM AT or compatible computer. The high memory area is highlighted.

See lessIf the voltage on pin 1 of the power supply is not in the range of _____ volts, the PC will not boot.
All PC power supplies provide at least +5VDC, +12VDC, and -12VDC. Some power supplies also provide +3.3VDC, -5VDC, and/or 5VSB. Another important aspect of voltage—one that varies greatly between power supplies—is regulation , which specifies how tightly voltages are controlled.

See lessWhat are the most likely conditions for ESD?
An ESD event may occur when the object comes into contact with a conductive path. For example, charged regions on the surfaces of styrofoam cups or bags can induce potential on nearby ESD sensitive components via electrostatic induction and an ESD event may occur if the component is touched with a mRead more

See lessWhat voltage does a 586 system use?
The 586-Engine can be powered with a single regulated 5V with the on-board 3.3V and 2.5V regulators. It also can be powered by external regulated 5V, 3.3V, and 2.5V.

See lessWhat configuration should a Volt-Ohm meter he set to when testing a fuse?
Set your ohmmeter to the lowest scale on the resistance setting. Usually, it will have Ω (Greek letter omega) for resistance. When testing a fuse, touch the end of each ohmmeter cable to the opposite ends of the fuse. A reading between 0 and 2 indicates continuity—the circuit is good/complete.

See lessOn a dot-matrix printer, regular lube maintenance should be followed, but this component should never be lubed:
For the dot matrix printer you need to clean the internal parts of this unit and you must put a lubricant on the moving parts of this machine, normally on the shaft where the print-head assembly is attached. Adjust the print-head spacing. Check the tension on the print-head-positioning belt.
