The device manager is a system tool that displays all the devices that are configured on a computer. It provides a comprehensive list of hardware devices such as printers, monitors, keyboards, and network adapters. The device manager allows users to view and manage device properties, update drivers, enable or disable devices, and troubleshoot any issues related to hardware devices. It is an essential tool for system administrators and advanced users to ensure proper functioning and maintenance of the computer's hardware components.

A fan is used to draw heat away from the CPU. Fans are commonly used in computer systems to cool down the CPU and prevent it from overheating. They work by circulating air around the CPU, dissipating the heat generated by its operation. The movement of the fan blades creates airflow, which helps to remove the hot air and bring in cooler air, thus maintaining a safe operating temperature for the CPU.

Class B fire extinguishers are designed to handle flammable liquid fires such as gasoline and kerosene. These types of fires involve combustible liquids that can easily spread and ignite. Class B extinguishers are effective in extinguishing these fires by smothering the flames and cutting off the oxygen supply. They are typically filled with a foam or dry chemical agent that can quickly suppress the fire. Therefore, it is appropriate to use Class B fire extinguishers for gasoline and kerosene fires.

Isopropyl alcohol is the correct solution to clean the contacts on a network adapter. Isopropyl alcohol is commonly used as a cleaning agent for electronic components because it evaporates quickly, leaves no residue, and is safe to use on sensitive electronics. It effectively removes dirt, dust, and oils from the contacts without causing any damage. Mild detergent, slightly abrasive cleanser, and glass cleaner may be too harsh or leave residue on the contacts, which could interfere with the proper functioning of the network adapter.

A SIMM (single inline memory module) is a small circuit board that holds several memory chips. SIMM is the correct answer as it is the acronym for single inline memory module, which accurately describes the function and form of the circuit board. The other options provided are variations of the same term, with different capitalization and hyphenation, but they all refer to the same concept of a small circuit board holding memory chips.

A yellow exclamation point in the device manager typically indicates that there is a problem with a specific device connected to the computer. This could be due to a variety of reasons such as outdated drivers, hardware conflicts, or malfunctioning hardware. The device manager is a tool in the computer's operating system that allows users to view and manage the hardware devices connected to their computer. When a yellow exclamation point appears next to a device in the device manager, it serves as a visual indicator that there is an issue with that particular device.

The default subnet mask for a Class A network is 255.0.0.0. In a Class A network, the first octet is used to identify the network, while the remaining three octets are used to identify the hosts. The subnet mask 255.0.0.0 indicates that the first octet is used for the network, allowing for a large number of hosts to be connected to the network.

The ATX power connector is used to connect the power supply to the motherboard. It is a standard power connector that provides power to the various components on the motherboard, such as the CPU, memory, and expansion slots. The ATX power connector is designed to be easy to connect and disconnect, making it convenient for users to upgrade or replace components in their computer.

The drum scanner is known for its high costs but is capable of producing top-quality images. Its high cost is mainly due to its advanced technology and capabilities, such as high resolution and color accuracy. Drum scanners use a cylindrical drum to scan the image, which allows for precise and consistent scanning, resulting in top-quality images. This type of scanner is often used in professional settings where image quality is of utmost importance, such as in graphic design, printing, and fine art reproduction.

The new client-server network configuration allows for central control of data resources and access, ensuring that all data is stored and managed in a centralized location. This improves efficiency and streamlines the management of data within the network. Additionally, the new configuration provides increased security in the event of hardware failures, as data is stored on dedicated servers rather than individual computers. This reduces the risk of data loss and ensures that data can be easily recovered in case of hardware failures.

A PATA (IDE) cable typically has 40 connectors. These connectors are used to connect the cable to various devices such as hard drives and optical drives. The cable has 40 pins, with each pin corresponding to a specific function or signal. The number of connectors is important as it determines the number of devices that can be connected to the cable simultaneously.
