To load a byte of data parallelly into a shift register with a synchronous load, there must be _____.
- A.
one clock pulse
- B.
one clock pulse for each 1 in the data
- C.
eight clock pulses
- D.
ne clock pulse for each 0 in the data

Show answer & explanation
Correct answer: A
Key idea: For a synchronous load, all bits of the data are captured simultaneously on a single clock edge. This means a whole byte can be loaded in one clock pulse when using synchronous parallel load.
By contrast, serial loading shifts bits in one at a time and would require eight clock pulses to load a byte.
Therefore, to load a byte of data in parallel into a shift register using a synchronous load, only one clock pulse is required. मुख्य बिंदु: सिंक्रोनस लोड में डेटा के सभी बिट्स एक ही क्लॉक एज पर एक साथ कैप्चर होते हैं। अतः शिफ्ट रजिस्टर में समानांतर रूप से एक बाइट डेटा लोड करने के लिए केवल एक क्लॉक पल्स की आवश्यकता होती है। Therefore the correct answer is: one clock pulse
