The first ATX power supplies and motherboards used a single power connector called the P1 connector that had 20 pins.

The Ohm is a unit of measurement used to quantify the resistance that a material or device offers to the flow of electric current. It represents the opposition encountered by the electrical current as it passes through a conductor. The higher the value in Ohms, the greater the resistance to the flow of electricity.

A capacitor is an electronic device that can store and release electrical energy. It is designed to hold an electrical charge for a period of time and can help to regulate and stabilize the flow of electricity in a circuit. Capacitors are commonly used in electronic devices to filter out noise, improve power factor, and store energy for later use.

Memory in the processor package, but not on the processor die, is referred to as Level 2 cache. This type of cache is located outside of the processor chip, usually on the same circuit board as the processor. It is used to store frequently accessed data and instructions, providing faster access compared to main memory. Level 2 cache acts as a buffer between the processor and main memory, helping to reduce the time it takes for the processor to retrieve data, thereby improving overall system performance.

Excessive heat can indeed damage the CPU and the motherboard. CPUs and motherboards are sensitive electronic components that generate heat during operation. If the heat is not properly dissipated, it can lead to overheating, which can cause permanent damage to the CPU and the motherboard. This can result in system instability, reduced performance, and in some cases, complete failure of the components. Therefore, it is important to ensure proper cooling and ventilation to prevent excessive heat buildup and protect the longevity and functionality of the CPU and motherboard.

The statement is true because as new technologies are developed and integrated into motherboards, they often require more power to function properly. This is because new technologies such as faster processors, more memory, and advanced graphics cards require more electrical power to operate efficiently. Therefore, the electrical requirements for motherboards do change over time to meet the demands of these new technologies.

Motherboards that support PCI Express and have the 24-pin P1 connector are sometimes called Enhanced ATX boards because the term "Enhanced ATX" refers to an extended version of the ATX motherboard form factor. These motherboards are designed to accommodate the higher bandwidth and power requirements of PCI Express technology, which allows for faster data transfer between components. The inclusion of the 24-pin P1 connector ensures proper power delivery to the motherboard and its components. Therefore, the term "Enhanced ATX" accurately describes these specific motherboards.

The question is asking for a term that represents the work or energy required to produce one watt of power in one second. The correct answer, "volt," is a unit of measurement in the International System of Units (SI) that represents the electrical potential difference or electromotive force. In the context of the question, it can be understood that one volt is the amount of energy required to produce one watt of power in one second.

The statement suggests that if you suspect a faulty power supply, the easiest solution is to replace it. This implies that replacing the power supply is a simple and effective way to fix any potential issues with it. Therefore, the correct answer is true.

When shopping for a motherboard for a gaming system, it is important to consider various factors such as form factor, processor sockets, chipsets, buses, number of bus slots, and other connectors, slots, and ports. These factors determine the compatibility and performance of the motherboard with the gaming system. Therefore, the statement "True" indicates that paying attention to these factors is indeed necessary when shopping for a gaming motherboard.

When removing the motherboard, it is common to find a main power line and possibly an auxiliary power line connecting the power supply to the motherboard. These power lines are essential for providing electricity to the motherboard and its components, ensuring that the computer functions properly. Therefore, the statement that there is a main power line and possibly an auxiliary power line from the power supply to the motherboard is true.

The memory on the processor die that is referred to as "Level 1" cache is the correct answer. This type of cache is the closest and fastest memory to the processor, providing quick access to frequently used data and instructions. It is typically small in size and is designed to minimize the time it takes for the processor to fetch data from main memory, improving overall system performance.

PCIe, which stands for Peripheral Component Interconnect Express, is not backward compatible. Backward compatibility refers to the ability of a newer version of a technology to work with older versions. In the case of PCIe, newer versions are not compatible with older versions. This means that if a device or component is designed for a specific version of PCIe, it may not work or may have limited functionality if connected to a different version of PCIe. Therefore, the correct answer is False.

MicroATX does not increase the total cost of a system by increasing the number of expansion slots on the motherboard. In fact, MicroATX is a smaller form factor motherboard that typically has fewer expansion slots compared to standard ATX motherboards. This smaller size often results in cost savings as it requires less materials and components. Therefore, the statement is false.

Most SIMMs (Single Inline Memory Modules) are designed to be inserted into their slots at an angle. This allows for easier installation and ensures a secure connection between the module and the slot. By sliding the module in at an angle, it aligns with the slot's pins and then can be pressed down to secure it in place. This angled insertion method is commonly used for SIMMs and helps to prevent any damage to the module or the slot during installation.

The kernel is the core of the operating system that is responsible for controlling security, managing the file system, providing a platform for applications to run on, and moderating the hardware. It is the central component that manages the system's resources and ensures that different software programs and hardware devices can communicate with each other effectively. The kernel plays a crucial role in maintaining the stability and security of the operating system.

The statement is false because power supplies and monitors do not contain enough power to give a strong shock even when they are plugged in. The voltage levels in these devices are low and designed to be safe for users. However, it is still important to exercise caution and follow proper safety measures when handling electrical equipment.

DRAM stands for Dynamic Random Access Memory. It is a type of computer memory that holds its data as long as the RAM has power. Unlike other types of memory such as ROM, which retains data even when power is removed, DRAM requires a constant power supply to maintain the stored data. This makes DRAM volatile memory, meaning that its contents are lost when the power is turned off. Other options like SO-DIMM, MicroDIMM, and SDRAM are form factors or different types of memory modules, but they do not specifically refer to the characteristic of holding data only as long as power is supplied.
