Can you formulate what a synchronous serial interface is?

Question

Computer networks

Accessible language. All that is googled: heavy schemes and a bunch of terms.

Answer 1

Briefly and clearly.

Answer 2

Not all things can be described in accessible language. To do this, you just need to read a few articles for 15 minutes, and then everything will be clear.
Try to explain in an accessible language what a green light is for a blind person? You will have to delve into the impenetrable jungle of terminology and descriptions of basic things. So here - if you do not understand the meaning of the name itself (that is, you do not understand what the words synchronism, sequence, interface mean), then simple, understandable words will not work.
Well, let's put it this way.
There are several devices, they are connected by wires. The signal to all devices goes simultaneously (synchronously). But the devices are connected via a bus, not a star, that is, in series.

Answer 3

Serial - means each bit of information is transmitted in its own time interval, sequentially, in turn, most often - along one signal line. An additional clock line may be present.
Asynchronous - a character on the line can occur at any time, and special actions are needed to recognize its beginning and end. As a rule, these are additional bits of information - a start bit and one or two stop bits. A byte (8 bits) is transmitted in 10 or 11 cycles, which reduces the speed.
But with synchronous transmission, a byte is transmitted in 8 bits, and a simple counter is used to divide the bit stream into bytes, in the case of a byte - up to 8. It also starts its work when it receives the corresponding signal - clock, special. symbol or otherwise. In this case, there is no additional information inside the data stream, and there is no decrease in speed.
The transmitted word may not correspond to a byte, it may have a different number of bits. Byte is just an example.
