COMPUTER FUNDAMENTALS

Detailed explanation-1: -Explanation: Computers, information appliances, digital cameras, digital televisions, flash memory, key USB memory, mobile phones, hard discs, and computer memory devices are examples of digital electronics. After analog signals have been transformed to digital form, digital signal processing is applied to them.

Detailed explanation-2: -There are two types of Digital Circuits: Combinational Digital circuits and Sequential Digital Circuits. Combinational Digital Circuits are the type of digital circuits in which output depends upon inputs at that present time.

Detailed explanation-3: -A Digital computer can be considered as a digital system that performs various computational tasks. The first electronic digital computer was developed in the late 1940s and was used primarily for numerical computations. By convention, the digital computers use the binary number system, which has two digits: 0 and 1.

Detailed explanation-4: -Computers are digital machines because at their most basic level they can distinguish between just two values, 0 and 1, or off and on. There is no simple way to represent all the values in between, such as 0.25. All data that a computer processes must be encoded digitally, as a series of zeroes and ones.
