A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter (VOM), as the unit is equipped with voltmeter, ammeter, and ohmmeter functionality.

What two devices in a computer should be considered black boxes and should never be opened?
What two devices in a computer should be considered “black boxes”, and should never be opened, due to risks involving charged capacitors? a. power supply and monitor 27.
Which device connect to the motherboard through a connector cable?
Typical systems have at least two such cables: a 34-wire ribbon cable connecting the floppy disk drive to the FDD controller interface on the motherboard, and an IDE cable connecting the hard drive and CD- or DVD-ROM drive to the primary IDE interface connector on the motherboard.
Which unit of electricity measures is used to measure the power consumption of a device?
Electricity consumption is measured in kilowatt-hour (kWh). A single kWh is defined as the energy consumed by an electrical device of power 1000 W...
What unit is used to measure the frequency of memory FSB and the processor?
(b) Hz is the answer.
What two components are considered black boxes?
In a way, a black box divides the world into two parts: the inside (implementation) and the outside.
What is the most common pointing device on laptops?
While the most common pointing device by far is the mouse, many more devices have been developed. However, the term mouse is commonly used as a metaphor for devices that move the cursor.
What configuration can you find for PCIe slots?
What configuration can you find for PCIe slots? PCIe card slots are commonly configured as x1, x2, x8, and x16 representing the number of lanes used for input/output. Some slots may be configured to run differently.
What is the main function of the motherboard?
The motherboard serves as a single platform to connect all of the parts of a computer together. It connects the CPU, memory, hard drives, optical drives, video card, sound card, and other ports and expansion cards directly or via cables.
What are motherboard connectors?
ATX Power Connector: This is the second of two power connections. This is the main power connection for the motherboard, and comes from the Power Supply. 10. IDE connectors or PATA connectors : IDE full form is Integrated Device Electronics.
How is electricity consumption measured?
The primary way electricity consumption is measured is with the unit “watt-hour”. ... A kilowatt-hour is 1000 watt-hours, which means using a 4000 watt air-conditioner for one hour will consume 4 kWh of electricity.
How do you measure how much electricity an appliance uses?
The wattage of most appliances is usually stamped on the bottom or back of the appliance, or on its nameplate. The wattage listed is the maximum power drawn by the appliance. Many appliances have a range of settings, so the actual amount of power an appliance may consume depends on the setting being used.
How do electric companies measure energy consumption?
Electrical Usage Is Measured in Kilowatt Hours
A watt is the product of the voltage and amperage (or current) in an electrical circuit: 1 volt x 1 amp = 1 watt. ... Your electric meter records electricity usage in kilowatt-hours. In simple terms, 1 kilowatt hour = 1,000 watt-hours.
What can DIMM use to hold data?
DIMM is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard. The DIMM stores each data bit in a separate memory cell. DIMMs use a 64-bit data path, since processors used in personal computers have a 64-bit data width.
What type of bus does PCI use?
Whereas PCI uses a 32-bit or 64-bit parallel bus, PCI Express uses a serial bus, which is faster than a parallel bus because it transmits data in packets similar to how an Ethernet network, USB, and FireWire transmit data.
