1.	Which method requires external authority and is inflexible?(a) Open loop method(b) Closed loop method(c) Open & Closed loop method(d) None of the mentionedThis question was addressed to me in an online interview.My doubt is from Synchronization and Network Synchronization topic in section Synchronization of Digital Communications
Answer» CORRECT answer is (a) Open loop method Explanation: Open loop method is inflexible, does not adjust quickly to UNPLANNED changes and NEEDS EXTERNAL authority that provides prior knowledge, where as closed loop method does not need all these.
