MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.

Detailed explanation-2: -Synchronous vs asynchronous communication. Synchronous communication takes place in real-time between two or more people. All parties are online at the same time. When a message or request is sent, there’s an immediate response.

Detailed explanation-3: -In modern computer networks, time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events happen. Time also provides the only frame of reference between all devices on the network.

Detailed explanation-4: -Disadvantages of asynchronous communication: Because the interaction isn’t in real-time, actions can’t be made immediately and require some time. Asynchronous communication can’t be an actual conversation because there’s quite a delay or lag between when the message is sent and when it is processed by the recipient.
