A keyboard, video, mouse KVM switch is a hardware device that can be used to control more than one computer using a single keyboard, monitor, and mouse. KVM switches provide cost-efficient access to multiple servers using a single keyboard, monitor, and mouse.

A thin client device is typically a type of low-end computer that does not perform any processing or data storage locally. A thin client relies on a network connection to access any resources required to perform computing tasks and operate software. A RAID controller controls the expansion of internal and external drives as well as providing fault tolerance for storage devices.

A capture card imports video information into a computer and records it to the storage device. SD storage cards are a form of removable storage used widely in portable devices.

The resistance of a circuit to the flow of current is measured in ohms O. Amps A measure the amount of electrons moving through the circuit. Watts W measure the work required to move electrons through the circuit. Volts V measure the work required to move a charge from one location to another. When the CPU is being replaced or upgraded, the correct voltage must be matched. Headphones, monitors, printers, speakers,scanners, fax machines, and projectors are all considered output devices.

Fingerprint scanners, keyboards, and mice are all considered input devices. Memory is the temporary storage area of data that is accessed by the CPU. L1 cache is internal cache and is integrated into the CPU. When building a computer, select a power supply with sufficient wattage to power all the components. Each component inside the computer uses a certain amount of power. Obtain the wattage information for the components from the manufacturer documentation. When deciding on a power supply, make sure to choose a power supply that has more than enough power for the current components.

The shape of the computer case is usually determined by the motherboard, power supply, and other internal components. Hey there Geeks! Hope you all are well.
