Q. Advantage of digital technology?

The primary advantage of digital technology is the low cost, simplicity, and versatility of the digital building blocks. Because digital signals have a finite number of discrete amplitudes at any given time, distinctive digital building blocks are developed to process them. Digital systems are built by repeating a very few simple blocks. The approach becomes very powerful because the blocks (mass-produced in enormous numbers) are inexpensive in IC form and can be repeated thousands of times.

The two-state nature of digital technology makes the binary number system its natural tool. In a binary system there are only two digits, namely, 0 and 1. The vast majority of present digital computers use the binary system,which has two binary digits (bits), 0 and 1. Internal representation of information in a digital computer is in groups of bits. Besides the binary system (base 2), in the digital world, the most commonly used number systems are octal (base 8) and hexadecimal (base 16).
