Choose two. Which two form factors are commonly used to build a new computer? What are the two connector types for the a interface? IRQ Which three system resources are commonly used for communication between the CPU or memory and other components in the computer?
Which technology would be best to use for drive redundancy and data protection? A technician receives a complaint of poor image quality after the user changes the native resolution. While investigating the complaint, the technician discovers there is a mismatch between native mode and the native resolution of the peripheral. Which item is configured incorrectly? Refer to the exhibit. Based on the advertisement that is shown , what is the native resolution of this computer system?
Which memory module has a front side bus speed of MHz? 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. The form factor pertains to the shape of the mother board and case. Additionally the case must accommodate the shape of the power supply.
Buffered memory has additional circuitry to manage the large amounts of RAM needed by server applications. 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.
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. 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. 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. IT Essentials v7.
