Asynchronous Data Transfer
Asynchronous Data Transfer Overview Asynchronous data transfer is communication between two digital components (or systems) that does not rely on a common clock . Transfer is coordinated using control signals (handshakes), so sender and receiver agree when data is valid and when it has been accepted. Use of asynchronous When the send…

I/O INTERFACE (Input/Output Interface)
I/O INTERFACE (Input/Output Interface) I/O Interface acts as an intermediate hardware unit between the CPU and peripheral devices to ensure smooth data transfer by matching speed, data format, and control signals. Need for I/O Interface Speed mismatch – Data format mismatch – Control and timing mismatch – Device selection and …
