Serial transmission is a method of data communication where data is sent one bit at a time over a single channel. It involves encoding the data into binary form and transmitting it sequentially with start and stop bits framing each data byte. Serial transmission is widely used in applications like computer peripherals, networking devices, and industrial automation. It offers simplicity, cost-effectiveness, and longer transmission distances but has lower data transfer rates compared to parallel transmission. Common examples of serial transmission interfaces include RS-232, RS-485, USB, and SPI.

7. It can occur at
regular intervals.
Isochronous
Types
It can occur at any
time.
Asynchronous
It can occur
continuously.
Synchronous

8. Asynchronous
 Data is transferred at
predetermined intervals based
on a predefined clocking signal.
 The data blocks are separated
and clustered at regular
intervals, with synchronous
characters preceding them
Synchronous
 A start bit precedes each
character, and one or more
stop bits follow it.
 Spaces frequently separate
characters.

9. Limitation of Serial Transmission
• It uses less number of lines for transmission
between devices.
• It occupies overhead of about 20% other than
useful information.
