They are typically implemented using flip-flops, which can hold a single binary bit (0 or 1). A combination of flip-flops creates a multi-bit register to represent the time. A clock circuit generates pulses at regular intervals (e.g., every second) to update the register values, keeping track of time.</p></li><li data-sourcepos="7:1-8:0"><p data-sourcepos="7:3-7:360" style="margin-right: 0px; margin-left: 0px; white-space-collapse: preserve; word-break: break-word;"><span style="font-weight: 700;">Computers:</span> Registers play a crucial role in the central processing unit (CPU) as temporary storage elements. They hold data (numbers, instructions) being processed by the arithmetic logic unit (ALU) and operands (values) involved in calculations. Registers also store intermediate results, addresses, and control signals essential for computer operation.</p></li></ul><p data-sourcepos="9:1-9:158" style="margin-top: 1rem; margin-right: 0px; margin-left: 0px; white-space-collapse: preserve; word-break: break-word; color: rgb(31, 31, 31); font-family: &quot;Google Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;"><span style="font-weight: 700;">In conclusion, the correct answer is (a) digital clocks.</span> Both digital clocks and computers heavily rely on register circuits for their core functionality.</p><p data-sourcepos="11:1-11:128" style="margin-top: 1rem; margin-right: 0px; margin-left: 0px; white-space-collapse: preserve; word-break: break-word; color: rgb(31, 31, 31); font-family: &quot;Google Sans&quot;, &quot;Helvetica Neue&quot;, sans-serif; font-size: 16px;">If you'd like to delve deeper into the specific types of registers and their applications in digital circuits, feel free to ask!</p>
