Different types of computers based on operations |
| Answer» Computers are classified in to three types based on their principles of operation. These\xa0three types of computers areAnalog computersDigital computersHybrid computersAnalog computersAnalog computer is a computer that performs operations using continuously varying signals such as voltage, current and frequency. In analog computers numbers are represented by continuously varying quantities such as voltage, current and frequency.\xa0Analog computers are mainly used for scientific and engineering purposes.\xa0These computers do not give completely accurate results. The accuracy of analog computers is less. Analog computers do not require memory for performing operations.Antikythera mechanism is the first known analog computer that is designed to predict astronomical positions and eclipses. This instrument was designed and constructed by Greek scientists between 150 and 100BC.Digital computersDigital computer is a computer that performs calculations and logical operations using electrical signal such as voltage that is represented in two digits 0 and 1.\xa0Where 0 and 1 represents two different voltages or states, 0 represents 0V or OFF state and 1 represents 5V or ON state. 0 or 1 is called bit.Most of the computers available today are the digital computers. The computers that we use at home or offices are digital computers.Hybrid computersHybrid computer is a computer that has features of both analog and digital computers. These computers use analog part for performing the mathematical calculations such as differential equations and digital part for performing the logical operations and for storing result. Hybrid computers have the speed of analog computer and accuracy of digital computer. | |

define artificial intelligence. What are its use.write with proper example |
| Answer» Artificial Intelligence is the branch of computer science dealing with the reproduction or mimicking of human-level intelligence, self awareness, knowledge, conscience, thought in computer programs.Applications of\xa0Artificial Intelligence:Optical character recognitionHandwriting\xa0recognitionFace\xa0recognitionSpeech recognitionComputer vision, virtual reality, image proceesing.For example: If you want to train a computer to recognize a pen from a pencil. Pens and pencils come in a variety of sizes, shapes, colors etc. Previously, you would have hard-coded the computer to test for every single one of those combinations before reaching a decision. With Machine Learning, you can just train it on 50 pens and pencils and it’ll infer, on its own, which attributes differentiate them from each other, for example, a lack of lead tip. This saves engineers hours and hours of coding and reduces the cost of development. | |
