Assume that the ratio of speeds of a sender and a receiver is 2. Also assume that the handshaking bits sent in asynchronous mode of communication have the rate of 1 bit per information bit. Then, which mode of communication will be the fastest?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	Serial synchronous
B	Serial asynchronous
C	Parallel synchronous
D	Parallel asynchronous
E	none

Explanation:

Detailed explanation-1: -Synchronous communication 100, 000/1, 000 = 100 frames. Overhead in bits; 100 x 48 = 4, 800 bits.

Detailed explanation-2: -A USART (universal synchronous/asynchronous receiver/transmitter) is hardware that enables a device to communicate using serial protocols.

Detailed explanation-3: -Asynchronous transmission is used for sending a small amount of data while the synchronous transmission is used for sending bulk amounts of data. Thus, we can say that both synchronous and asynchronous transmission are essential for the overall process of data transmission.

Detailed explanation-4: -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. In this way, synchronization is achieved.
