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
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.
The ICH
A router or a Layer-3 switch can connect 2 or more LANs together and control data flow between them.

Ethernet.
The direct memory access or DMA mode of data transfer is the fastest amongst all the modes of data transfer.In this mode ,the device may transfer data directly to/from memory without any interference from the CPU.The device requests the CPU through a DMA controller to hold its data,address and control bus so that the device may transfer data directly to/from memory.
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
