Test On Expansion Slot And Ports

Explanation
The MCA (Micro Channel Architecture) supports multiple bit sizes, including 8-bit, 16-bit, and 32-bit. This means that devices or components designed to work with MCA can be implemented using any of these bit sizes. However, the given question does not mention whether 64-bit is supported or not, so we cannot include it as an option.

Explanation
The clock speed of VESA in a 486 DX2 machine was 40 MHz. The VESA (Video Electronics Standards Association) was a local bus standard used in computers during the 1980s and 1990s. The 486 DX2 was a popular processor in that era, and it operated at a clock speed of 40 MHz. This clock speed determined the speed at which the processor could execute instructions and perform calculations.

Explanation
The correct answer is 9 Pin, M. This indicates that the COM port has 9 pins and it is a male connector.

Explanation
USB 1.0 supports a data transfer rate of 12 MBPS (megabits per second). USB 1.0 was the first version of the Universal Serial Bus standard, introduced in 1996. It provided a significant improvement over previous connection options, such as serial and parallel ports. With a transfer rate of 12 MBPS, USB 1.0 allowed for faster and more efficient data transfer between devices, making it suitable for a wide range of applications. However, it has been surpassed by newer USB versions, such as USB 2.0 and USB 3.0, which offer even faster transfer speeds.

Explanation
The USB supports a maximum of 127 devices in a chain. This is because USB uses a 7-bit addressing scheme, allowing for a total of 127 unique addresses. Each device connected to the USB chain requires a unique address, and the USB controller reserves one address for itself. Therefore, the maximum number of devices that can be connected in a USB chain is 127.

Explanation
USB 2.0 supports a data transfer rate of 480 Mbps. This means that it is capable of transferring data at a speed of 480 megabits per second. This high speed allows for fast and efficient transfer of files and data between devices.

Explanation
The DIN-6 has 6 pins and is a female connector.

Explanation
The DIn-6 consumes 5 V to work.

Explanation
The PS-2 Mouse port is typically colored green. This color coding convention helps users easily identify and connect the PS-2 mouse to the correct port on their computer.

Explanation
When purchasing a new mouse, one important thing to consider is the mouse attachment. The attachment refers to the way the mouse connects to the computer, whether it is wired or wireless. This is crucial because it determines the convenience and flexibility of using the mouse. A wired mouse ensures a stable connection but may limit mobility, while a wireless mouse allows for freedom of movement but requires batteries or charging. Therefore, considering the mouse attachment is essential in choosing a mouse that suits the user's preferences and needs.

Explanation
The Line-Out port of a Sound Port is typically colored green. This color coding helps users easily identify and connect the correct audio devices to the appropriate ports on their computer or audio system. The Line-Out port is used to connect speakers or headphones to the sound port, allowing audio output from the device to be heard.

Explanation
IEEE1394a, also known as FireWire, is a high-speed serial bus standard that supports data transfer rates of up to 400 Mbps. It can support a maximum of 63 devices in a daisy-chain configuration. Therefore, the correct answer is "400 MBPS with 63 Device in a chain."

Explanation
COM 1 and COM 2 are both examples of serial ports. Serial ports are used to connect devices, such as printers or modems, to a computer. COM 1 and COM 2 are commonly used designations for serial ports in Windows operating systems. LPT 1 and LPT 2, on the other hand, are examples of parallel ports, which are used for connecting devices that require high-speed data transfer, such as printers.

Explanation
The EISA (Extended Industry Standard Architecture) was released in the year 1984.

Explanation
The user can use the COM1 attachment with a new keyboard. The PS-2 port is not functioning properly, so the user needs an alternative connection method. COM1 is a serial port that can be used to connect peripherals such as keyboards.

Explanation
The PS-2 and USB ports are able to provide power. PS-2 ports are commonly used for connecting keyboards and mice, and they can provide power to these devices. USB ports, on the other hand, are versatile ports that can be used for various devices such as keyboards, mice, printers, and external hard drives. USB ports are designed to provide power to these devices, making them convenient for charging or powering devices.

Explanation
The MCA (Micro Channel Architecture) supports a data bus speed that ranges from 10 - 12 MHz. This means that the MCA system can transfer data at a rate of 10 to 12 million cycles per second. This range of bus speed allows for faster data transfer and improved performance compared to lower speed ranges.
