Classification of Computing Devices
Computer Studies · 50 practice questions
Classification by generation (first to current, with year of development, basic components/technology, speed and storage capacity); by size (micro, mini, mainframe, super); by purpose (general purpose, special purpose); by type (digital, analog, hybrid) - personal computers, desktops, laptops, tablets, hand-held devices, servers, workstations, mainframes, wearables and supercomputers.
- Relate each generation to its characteristic features.
- Differentiate the classification of computing systems by size.
- Differentiate among the various types of modern computer systems in respect of size, basic components, data and usage.
- State the importance and use of these computing systems.
Try a few questions
- Practice question 1
Classification by type distinguishes computers based on how they process data:
- A.micro, mini, or mainframe
- B.general-purpose or special-purpose only
- C.digital, analog, or hybrid
- D.laptop, desktop, or tablet only
Show the answer
C. digital, analog, or hybrid
This classification specifically groups computers by their underlying method of processing data.
- Practice question 2
An analog computer processes data represented as continuously varying physical quantities, such as
- A.text characters exclusively, rather than continuous values
- B.binary digits exclusively, rather than continuous values
- C.voltage or pressure, rather than discrete digital values
- D.punched card patterns exclusively
Show the answer
C. voltage or pressure, rather than discrete digital values
Analog computers work directly with continuously variable physical quantities, such as voltage, rather than discrete binary data.
- Practice question 3
A hybrid computer combines the features of both digital and analog computers, processing
- A.neither continuous nor discrete data
- B.only discrete data, like a purely digital computer
- C.only continuous data, like a purely analog computer
- D.both continuous and discrete data
Show the answer
D. both continuous and discrete data
Hybrid computers are designed to handle both the continuous data typical of analog systems and the discrete data typical of digital systems.
