Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Type of computer data transmission in which start/stop transmission bits are not required is termed as
A
synchronous
B
pulse
C
asynchronous
D
intermittent
Explanation: 

Detailed explanation-1: -The Synchronous transmission mode is a mode of communication in which the bits are sent one after another without any start/stop bits or gaps between them. Actually, both the sender and receiver are paced by the same system clock.

Detailed explanation-2: -Edit online. The term asynchronous is used to describe the process where transmitted data is encoded with start and stop bits, specifying the beginning and end of each character. An example of asynchronous transmission is shown in the following figure.

Detailed explanation-3: -Edit online. The term synchronous is used to describe a continuous and consistent timed transfer of data blocks. These types of connections are used when large amounts of data must be transferred very quickly from one location to the other.

Detailed explanation-4: -What Does Asynchronous Transmission Mean? Asynchronous transmission is the transmission of data in which each character is a self-contained unit with its own start and stop bits and an uneven interval between them. Asynchronous transmission is also referred to as start/stop transmission.
