Computer Hardware (Master) Quiz

RAM stands for Random Access Memory, which is a type of computer memory that allows data to be accessed in any random order, rather than in a sequential manner. It is a volatile memory, meaning that its contents are lost when the power is turned off. RAM is used by the computer to temporarily store data that is actively being used by the CPU, such as program instructions and data. It provides fast and temporary storage for data that can be quickly accessed by the CPU, improving the overall performance of the computer.

The motherboard is a crucial component of a computer that connects and allows communication between all the other hardware components. It contains numerous tiny electrical paths, called traces, which form a complex network to facilitate the flow of data and power between the CPU, RAM, storage devices, graphics card, and other peripherals. These electrical paths ensure that all the components work together seamlessly, making the statement "The motherboard uses tiny electrical paths to connect each component of the computer together" true.

The statement is true because in a computer's control unit, each time it fetches and decodes data, it is referred to as an instruction cycle. This cycle involves retrieving the next instruction from memory, decoding it to understand what operation needs to be performed, and then executing that operation. This process is repeated for each instruction in a program, allowing the computer to carry out the desired tasks.

Expansion slot openings are indeed located on the back of the computer. These openings are designed to allow users to add additional hardware components to their computer, such as graphics cards, sound cards, or network cards. By placing the expansion slots on the back, it makes it easier for users to access and install these components without having to open up the entire computer case.

Motherboards with integrated audio have built-in sound capabilities, eliminating the need for a separate sound card. This means that users can directly connect speakers or headphones to the motherboard's audio ports and enjoy sound without the need for additional hardware. Integrated audio has become a standard feature in modern motherboards, offering convenience and cost savings for users who do not require high-end audio capabilities. Therefore, the statement "Motherboards with integrated audio, (or sound), do not need a sound card" is true.

The power supply is responsible for providing power to various components in a computer system. In this case, it supplies power to the drives, certain expansion cards, and the motherboard. The motherboard is a crucial component that connects all the other hardware components together, allowing them to communicate and function properly. Therefore, it is essential for the power supply to supply power to the motherboard in order for the entire system to work correctly.

Most motherboards have two IDE connectors. These connectors are used to connect IDE devices such as hard drives and optical drives to the motherboard. Having two connectors allows for the connection of multiple IDE devices simultaneously, providing the user with more storage and expansion options.

The AGP expansion slot connects AGP video cards to the motherboard. The motherboard is the main circuit board of a computer system and serves as a platform for connecting various components, including the CPU, GPU, and other peripherals. The AGP slot specifically allows for high-speed communication between the video card and the motherboard, enabling the video card to process and render graphics efficiently.

False. DIMM stands for Dual In-Line Memory Module, which means that there are multiple memory chips on both sides of the module. Each memory chip has its own set of contact points, and these contact points are not connected together between the two sides of the DIMM. Therefore, the statement is incorrect.

The BIOS (Basic Input/Output System) is a firmware that is responsible for initializing and configuring the computer's hardware components during the boot process. It performs a series of tests and checks to ensure that all hardware devices are functioning properly. Additionally, the BIOS provides the necessary instructions for the operating system to load and start. Therefore, the correct answer is "Set up the computer's hardware."
