STRENTGHS & WEAKNESSES OF A COMPUTER
SPEED: Computers are much faster as compared to human beings.
HIGH STORAGE CAPACITY: Computers can store a large amount of information in very small space.
ACCURACY: Computers can perform all the calculation & comparisons accurately provided the hardware does not malfunction.
VERSATILITY: Computers can perform repetitive jobs efficiently.
TYPES OF COMPUTER
The computers have been classified into three categories.
Digital Computers -
The digital computer work upon discontinuous data. They convert the data into digits & all operations are carried out on these digits at extremely fast rates. Digital Computers are much faster than analog computers. Computers used for business & scientific applications are digital computers.
In analog computers continuous quantities are used. The main advantage of analog computer is that all calculations take place in parallel & hence these are faster. Analog computers are mostly used in engineering & scientific applications.
In these computers some calculations take place in analog manner & rest of them take place in digital manner. Hybrid computers are used in hospitals where analog part is responsible for measurement of heart beat. They are also used in weather forecasting.
