Ans. Difference between a digital and hybrid computer:

Digital Computers:

These are general purpose computers. They accept data in the form of discrete digits (0 and 1). They have large storage capacity. They come in many sizes and shapes. They are generally used in every field of life. They are slow but accurate as compared to analog computers.

Hybrid Computers:

Hybrid computers combine best features of analog and digital computers i.e. speed, accuracy reliability etc. They are special purpose computers, which are fast and accurate. Hybrid computers help the user to handle both analog and digital type of data.

Difference between analog and hybrid computer?

analog computers,continuous quantities are used. computation are carried out physical quantities such as voltage,length,current,temperature etc. the devices that measure such quantities are analog devices example voltmeter,ammeter.hybrid computer the best qualities of both the digital and analog computer. hybrid computers are best used in hospital. hybrid computers are also used in wheather forecasting.


What short notes on Hybrid computer?

Hybrid computers are the computers that have the features of both digital and analog computers.The idea behind this hybrid computers is to create a working unit that offers the best of both types of computer.it uses analog components for computational purposes and digital components for processing and storage of results.E.g; hybrid computers are used at the space launch system when sending astronauts in the space for scientific research and exploration.This computer measures the temperature,wind,speed,the humidity of the space and then translated these quantities into digital form for analysis and processing.


Is a Radar a hybrid computer?

Usually no. "Digital radars" convert the analog signal to digital, and use a digital computer to process it to understand what's happening out there. That's a hybrid system but not a hybrid computer. Some radars in the 1970s did part of the computing by analog methods. That was a hybrid computer.


What is the purposes of hybrid computer?

A hybrid computer is a type of computer that is no longer made. It contains two interconnected computers: a digital computer and an analog computer. In most hybrid computers, part of the analog computer's program is entered manually by plugwires on plugboards and part by the digital computer switching relays and setting digitally controlled pots. The digital computer program was entered from tape or disk.Most of them were custom built systems generally used for control system simulation modeling. The analog computer was programmed to model an open loop real world system and the digital computer was programmed to control it and thereby close the loop. Some systems tested this way were:Nuclear Reactor control systemsAircraft flight control systemsChemical reaction control systemsIndustrial process control systemsetc.Another use of hybrid computers was high speed drawing of "stroke graphics" (dots, vectors, arcs) on random deflection high brightness CRT displays (another long gone technology).The last hybrid computers I saw operating were in about 1986. Haven't heard of any made since then.


What are the ten differences between analog and digital computer?

The difference between an analog and digitialcomputer is the type of data they process. Analog computers process measured data. A speedometer in your car is a common type of analog device. A digital computer processed descrete data (digits). In this case 0 and 1. Digital computers are most common. PC's, MAC's are digital computers. A big difference is an analog computer's output can vary even if the input is identical. A digital computer can be very precise. For instance, a gas pump might tell you that you pumped in 5 gallons of gas but you could have gotten 4.99 gallons or 5.01 gallons. If you asked a digital computer to add 5 and 6 together, you will always get 11. By the way. A gas pump is actually a hybrid computer. Although it processes measured data, that is how much fluid has passed through the gas hose, the data displayed to you, the amount of gas and how much you owe is in a digital format.
