Test On Expansion Bus

Explanation
The MCA (Micro Channel Architecture) supports 8-bit, 16-bit, and 32-bit systems. This means that the MCA can be used with computers that have different data bus sizes, allowing for compatibility and flexibility. The MCA is not limited to any specific data bus size, making it suitable for a wide range of applications. Therefore, the correct answer is 8 bit, 16 bit, and 32 bit.

Explanation
The correct answer is 40 MHz. The 486DX4 Vesa processor worked at a clock speed of 40 MHz.

Explanation
Multiple white slots available at any PCB are PCI. PCI stands for Peripheral Component Interconnect, which is a type of expansion slot that allows for the connection of various devices to the motherboard. These slots are commonly found on desktop computers and are used for adding expansion cards such as graphics cards, network cards, and sound cards. The other options listed (ISA, EISA, AGP) are also types of expansion slots, but they are not commonly used in modern computers.

Explanation
The AGP 8X runs at a clock speed of 533 MHz. AGP (Accelerated Graphics Port) is a type of expansion slot used for connecting graphics cards to a computer's motherboard. The 8X refers to the data transfer rate, which is eight times faster than the original AGP specification. The clock speed of 533 MHz means that data can be transferred at a rate of 533 million cycles per second, providing faster and smoother graphics performance.

Explanation
AGP (Accelerated Graphics Port) is the correct answer because it is a dedicated slot on the motherboard that has its own Math Co-Processor. The Math Co-Processor, also known as the Floating Point Unit (FPU), is responsible for performing complex mathematical calculations and is particularly important for tasks such as 3D graphics rendering. AGP was specifically designed to provide high-speed communication between the graphics card and the computer's CPU, allowing for improved graphics performance. The other options, PCI, PCIE, and PCIX, do not have their own Math Co-Processor and are not specifically designed for graphics processing.

Explanation
The Mini-DIN 6 connector has 6 pins.

Explanation
The PS2 port consumes 5 volts of power.

Explanation
The Line-Out port of a sound port is typically colored green. This port is used to connect external speakers or headphones to the computer or audio device. The green color coding helps users easily identify the Line-Out port among other ports on the device.

Explanation
USB (Universal Serial Bus) is the correct answer because it is a widely used interface that can support up to 127 devices simultaneously. USB allows for easy plug-and-play connectivity and is commonly used for connecting peripherals such as keyboards, mice, printers, and external storage devices to computers. The other options, IEEE 1394 a and IEEE 1394 b (also known as FireWire), are capable of supporting multiple devices but have a lower maximum limit compared to USB. LPT (Parallel port) is an older interface primarily used for connecting printers and has a much lower device limit compared to USB.

Explanation
IEEE 1394, also known as FireWire, is a high-speed serial bus interface commonly used for connecting devices such as computers, cameras, and external hard drives. The maximum number of devices that can be connected to an IEEE 1394 bus is 63. This limitation is due to the addressing scheme used by the bus, which allows for a maximum of 63 unique device addresses. Therefore, the correct answer is 63 Devices.

Explanation
The red strap in the IDE data bus must be in front of P1 because P1 represents the primary IDE channel. The red strap is used to indicate the location of pin 1, which is the first pin in the IDE connector. Placing the red strap in front of P1 ensures that the IDE device connected to the primary IDE channel is properly aligned and connected.

Explanation
When purchasing a new mouse, Mr. Shyam Lal needs to consider the connector type. This is important because the connector type determines how the mouse will connect to his computer or device. There are different connector types available such as USB, Bluetooth, or wireless. Mr. Lal needs to choose a mouse with a connector type that is compatible with his computer or device to ensure proper functionality.

Explanation
The DVI-D supports only digital signals. Unlike DVI-A, which supports only analog signals, DVI-D is designed specifically for digital video transmission. It does not support analog signals or any other form of data transmission. Therefore, the correct answer is "Only Digital."

Explanation
USB 1.0 supports a data transfer rate of 12 MBPS. This means that it can transfer data at a maximum speed of 12 megabits per second.

Explanation
The PS2 port is the correct answer because it not only provides a signal but also supplies power. The PS2 port is commonly used for connecting keyboards and mice to a computer, and it is designed to provide both data communication and power to the connected devices. This allows the devices to function without requiring additional power sources.

Explanation
USB 2.0 supports a data transfer rate of 480 MBPS. This means that it can transfer data at a speed of 480 megabits per second. USB 2.0 is an older version of the Universal Serial Bus (USB) standard and is capable of faster data transfer compared to its predecessor, USB 1.1. The higher data transfer rate of USB 2.0 allows for quicker and more efficient transfer of files and data between devices.

Explanation
The PS2 port has 6 pins.

Explanation
The BUS Mastering technology was supported by VESA.
