|
Detailed explanation-1: -Computer is capable of processing digital as well as analog signals.
Detailed explanation-2: -3) Hybrid Computer It accepts analogue signals and convert them into digital form before processing. So, it is widely used in specialized applications where both analogue and digital data is processed.
Detailed explanation-3: -Computers are digital in nature. Computers process, store, and communicate information in binary form, i.e. in the combination of 1s and 0s which has specific meaning in computer language.
Detailed explanation-4: -A digital computer processes information using binary digits (bits) representing either a 0 or a 1. These bits are processed by digital circuits and devices such as transistors and logic gates. Analog computers use analog circuits and devices such as amplifiers, resistors, and capacitors to perform calculations.
Detailed explanation-5: -Digital signals are used in communication mainly because of negligible impact on quality due to noise. Digital signals also become weaker as they traverse and can be amplified using digital regenerators. The regenerated digital waves can be of better quality, with no noise interference.
