Which is faster Hi Speed USB or SuperSpeed USB?
Which is faster, a Hi-Speed USB port or a SuperSpeed USB port? SuperSpeed USB is faster than Hi-Speed USB. What type of output does an S/PDIF port provide? Connect to external home theater audio system that provides the best signal quality and digital audio output.
What is a dual-voltage selector switch?
The dual-voltage selector switch is used to convert the input house voltage to an appropriate voltage so that the components inside the computer can use this voltage and operate. This switch converts the input voltage to 115 V in the United States or to 220 V in other countries.
What is the best way to determine if a cable inside a computer is a data and instruction cable or a power cable blank 1 Fill in the blank read surrounding text?
The best way to determine if a cable inside a computer is a data and instruction cable or a power cable is by its location in the computer because data and instruction cable are attached to the motherboard and power supply has its own separate cable for power .
What is the function of 115 230 switch?
This switch is used to set the input voltage to the power supply to either 110v/115v or 220v/230v.
Is my voltage 115 or 230?
In the United States, Alternating Current (AC Power) is provided in the 120V range. So if you are in the USA, you would use the 115V switch position. Europe and other countries use the 230V range so if you took your computer to one of those location you would have to switch to the 230V setting.
What are the three main components of a computer’s hardware?
Computer Hardware – CPU, RAM, and persistent storage Now let’s talk about the three major parts that make up a computer — CPU, RAM, and Persistent Storage. These three are found in all computers: laptops, smartphones, and tablets.
What is the definition of a surge protector?
This is absolutely a helpful device. What is a Surge Protector? The surge protector definition is an electrical device that protects the computer system as well as various electronic devices from sudden voltages within electrical power otherwise transient voltage that supply from the power supply.
How do you test a surge supressor circuit?
Here’s a story: Back when I was doing power supplies one product needed a qualification test to see if it would safely isolate itself from the AC line for a fault. Isolation was achieved by using a huge (size of a frozen orange juice can) SCR to short the input and literally fuse the input wiring.
How is Isolation achieved in a surge supressor?
Isolation was achieved by using a huge (size of a frozen orange juice can) SCR to short the input and literally fuse the input wiring. Hey, the method was in the unit design spec for this military supply.
What happens if you undersize a surge supressor?
Undersize a protector to fail on a surge that is not typically destructive. The surge can damage a protector but not any appliances. Then naive consumers (who also do not read manufacturer spec numbers) will recommend that protector. That light only reports when the protector was grossly undersized.
