1.	What is the speed of the 8250 UART?(a) 4800bits/sec(b) 1200bits/sec(c) 12000bit/sec(d) 9600bits/secThe question was posed to me in an interview for job.This intriguing question originated from UART Protocol topic in chapter Internet Principles of IOT
Answer» Right CHOICE is (d) 9600bits/sec To explain: The 8250 UART has ONE character BUFFER for the receiver and the transmitter each, which meant that communications software performed poorly at speed above 9600bits/sec, ESPECIALLY it operating under a multitasking system or if handling interrupts from disk controllers.
