IT Essentials Chapter 1 Quiz Answers Online

The chipset on a motherboard consists of integrated circuits that control how system hardware interacts with the CPU and motherboard. It also provides the capability and features needed, such as the maximum memory supported on the motherboard, multiple USB ports, eSATA connections, surround sound, and video.

Faster RAM will help the processor to keep all of the data in sync because the data that it needs to calculate can be retrieved when it is needed. The more RAM that the computer has, the less often the computer needs to read from slower storage such as hard drives or SSDs.

Memory is the temporary storage area of data that is accessed by the CPU. The fastest memory is known as static RAM (SRAM). Because SRAM is so fast, it is typically used as L1 cache. L1 cache is internal cache and is integrated into the CPU.

When the CPU is being replaced or upgraded, the correct voltage must be matched. The CPU voltage can be set in the BIOS or UEFI software.

Buffered memory has additional circuitry to manage the large amounts of RAM needed by server applications.

Headphones, monitors, printers, speakers,scanners, fax machines, and projectors are all considered output devices. Fingerprint scanners, keyboards, and mice are all considered input devices.

The form factor pertains to the shape of the mother board and case. Additionally the case must accommodate the shape of the power supply.

A USB to Ethernet adapter would be required to allow connectivity to a LAN in this scenario.

Overclocking is a technique that is used to make a processor work at a faster speed than its original specification. Overclocking is not a reliable way to improve computer performance and can result in damage to the CPU.

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.

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.

Do not open a power supply. Electronic capacitors located inside a power supply can hold a charge for extended periods of time, even after the main power has been disconnected.

A RAID controller controls the expansion of internal and external drives as well as providing fault tolerance for storage devices. The I/O card allows additional I/O ports to be added to a computer. 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.

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.

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.
