tri state devices carry either 0 or 1 which represents the current state o the data bus. If the tri-state device stores 1, then the data bus carries information.If the tri-state device carries 0,then the data bus is empty.
the device is responsible of transfering the data from peripherial devices to its local buffer storage
The read and write control lines running through the data buses have control signals. The microprocessor can read data from memory or write data to the memory so the data buses are bidirectional. One direction is needed to write the data while another direction is required for the read command to fetch the data.
A remote control is used to control an electronic device form a distance without wires. It uses infrared or radio frequencies to transmit the data to the device.
flow control
tri state means three states of operation. usually it is used on data buss whereby data is transferred to peripheral devices called I/O the transfer is 0 or 1 on a try state device if not zero or one the buss goes to open state which makes a tri state device.
Flow Control
The ICH
A router or a Layer-3 switch can connect 2 or more LANs together and control data flow between them.
A serial port is neither strictly an input device nor an output device; rather, it is a communication interface that can handle both input and output data. It allows for the transmission of data between a computer and peripheral devices, such as modems or printers. Depending on the direction of data flow, a serial port can function as an input, output, or both simultaneously.
output
The network topology that sends data in one direction only is called a "ring topology." In a ring topology, each device is connected to two other devices, forming a circular data path. Data travels around the ring in a single direction, passing through each device until it reaches its destination. This setup can simplify the transmission process but may lead to issues if one connection fails, as it can disrupt the entire network.
