SONET
A character-oriented synchronous protocol
HTML is synchronous because the base protocol, HTTP (Hypertext Transfer Protocol) does not maintain a connection with the server. This was because, at the time, no one could imagine wanting a protocol that kept state. Give that the protocol doesn't track the user, there'd be no way for HTML to by asynchronous.
CAN protocol is synchronous, as it relies on a fixed timing mechanism for communication between nodes. This timing mechanism establishes when messages can be transmitted and ensures they arrive at the intended recipient without delays.
A USART protocol is computer hardware/software that converts parallel data signals to serial data signals. USART is an abbreviation for Universal Synchronous/Asynchronous Receiver/Transmitter.

Synchronous buses use a clock signal to synchronize data transfers between components, ensuring that data is transferred at a predictable rate. Non-synchronous buses transfer data without a clock signal and rely on other mechanisms to coordinate data transmission. Synchronous buses are generally faster and more efficient but can be more complex to design and implement compared to non-synchronous buses.
1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
A USART protocol is computer hardware/software that converts parallel data signals to serial data signals. USART is an abbreviation for Universal Synchronous/Asynchronous Receiver/Transmitter.
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
An example would be HTTP
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
