MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Asynchronous serial communication is a communication interface in which the signals used are not synchronized to each other using a common clock signal. Instead, start and stop bits are used to indicate the beginning and end of a data message.

Detailed explanation-2: -The key difference between synchronous and asynchronous communication is synchronous communications are scheduled, real-time interactions by phone, video, or in-person. Asynchronous communication happens on your own time and doesn’t need scheduling.

Detailed explanation-3: -Asynchronous transmission is a type of data transmission which works on start and stop bits. In Asynchronous transmission, each character contains its start and stop bit and irregular interval of time between them.

Detailed explanation-4: -In source synchronous synchronization a common clock synchronizes communication. The transmitting device sends the clock signal to the receiving device. Devices with onboard (internal) clocks divide down the onboard clock to get the desired frequency. This, however, gives a course resolution.
