Three BUS Architecture
In a three BUS architecture, there are multiple buses that connect different components of a computer system. Each bus is responsible for transferring data between specific sets of components. In this architecture, there are two types of buses: input bus and output bus.
Input and Output Ports
- Input ports: These ports are used to receive data from external devices or other components of the computer system. They allow the computer to accept input from sources such as keyboards, mice, and other devices. The data received through the input ports is then processed by the computer.
- Output ports: These ports are used to send data from the computer system to external devices or other components. They allow the computer to provide output to devices such as monitors, printers, and speakers. The data sent through the output ports is displayed or used by the connected devices.
Understanding the Options
a) 2 output and 2 input: This option implies that there are two output ports and two input ports. However, in a three BUS architecture, there are typically more than two ports of each type to accommodate the connection of multiple devices.
b) 1 output and 2 input: This option implies that there is one output port and two input ports. Again, this contradicts the typical configuration of a three BUS architecture, where there are more than one output and input ports.
c) 2 output and 1 input: This option correctly states that there are two output ports and one input port. In a three BUS architecture, this configuration allows for multiple devices to receive data from the computer system while only one device can send data to the computer.
d) 1 output and 1 input: This option implies that there is only one output port and one input port. However, in a three BUS architecture, multiple devices need to be connected to both the input and output buses to facilitate communication.
Conclusion
In a three BUS architecture, the correct configuration for input and output ports is option 'C': 2 output and 1 input. This configuration allows for multiple devices to receive data from the computer system while only one device can send data to the computer.
