Computer Types

Question What are the three main categories for classifying computers? tap to flip ↻ Answer By **type**, by **size**, and by **purpose**. Question What are the three types of computers under 'By type'? tap to flip ↻ Answer **Analog**, **Digital**, and **Hybrid** computers. Question What are the three size-based classifications of computers? tap to flip ↻ Answer **Super**, **Mainframe**, and **Mini/Micro** computers. Question What are the two purpose-based classifications of computers? tap to flip ↻ Answer **General Purpose** and **Special Purpose** computers. Question What kind of data does an analog computer process? tap to flip ↻ Answer **Analog data** in the form of physical phenomena such as electrical, hydraulic (water flow), or mechanical processes. Question How do analog computers operate? tap to flip ↻ Answer They operate by **measuring** rather than by **counting**. Question What is the nature of input and output in an analog computer? tap to flip ↻ Answer It accepts input that **varies continuously** and gives output that performs a desired operation. Question Where are analog computers commonly used? tap to flip ↻ Answer In **process control plants**. Question What is a digital computer? tap to flip ↻ Answer A computer that performs **calculation and logical operations with digits**. Question What number system do digital computers use? tap to flip ↻ Answer **Binary code** — using only **0** and **1**. Question What happens to data in a digital computer before operations are performed? tap to flip ↻ Answer Data is **converted into digits** and then all operations are done in binary code. Question What are the primary uses of digital computers? tap to flip ↻ Answer **Business** and **scientific** uses. Question What is a hybrid computer? tap to flip ↻ Answer A computer that utilizes the **best qualities of both analog and digital** computers. Question When is a hybrid computer best used? tap to flip ↻ Answer In situations where the **display is required in analog format** and the **data collected is in analog format**. Question Give two examples of hybrid computers. tap to flip ↻ Answer **ICU machines** and **traffic signal design** systems. Question Which type of computer measures rather than counts? tap to flip ↻ Answer **Analog** computers. Question Which type of computer is described as the best and fastest way for calculations? tap to flip ↻ Answer **Digital** computers. Question Which computer type combines analog and digital capabilities? tap to flip ↻ Answer **Hybrid** computers. Question What is the key difference between analog and digital computers in terms of data handling? tap to flip ↻ Answer **Analog** computers process **continuous** physical phenomena by measuring; **digital** computers convert data into **discrete binary digits** (0 and 1) and count/calculate. Question A computer used in a process control plant that accepts continuously varying input is most likely which type? tap to flip ↻ Answer An **analog** computer. Question A computer used for business and scientific calculations using binary code is which type? tap to flip ↻ Answer A **digital** computer.
