Classification of Computers.


i. Classification of Computers by Size


a) Micro-Computers


• Micro –Computers are the Smallest class of Computers
• Micro- Computers have one micro-processor in its Central Processing Unit
• Micro-Processor refers to Central Data Processing Unit of a Micro-Computers
• Micro- Computers can serve one user at ago.
• Micro- Computers are commonly used in modern Offices.


b) Mini- Computers

• Mini- Computers are Medium-Sized Computers
• Mini- Computers can serve Two or more users at ago
• Mini- Computers have Two Micro-Processors in its Central Processing Unit
• Mini- Computers can support Telecommunication hence facilitate Sharing of Information
through computers which are Networked together.
• Mini- Computers are commonly in Banks and Super- Markets.


c) Main-frame Computers


• Main-frame Computers used in Large organization
• Main-frame Computers can serve several users at ago
• Main-frame Computers Several Micro-Processors in its Central Processing Unit
• Mainframe Computers can support Telecommunication hence facilitate Sharing of
Information through computers which are Networked together.
• Mainframe Computers are commonly used in Large Organizations such as International
Monetary Fund and World Bank, Insurance Companies, etc.


d) Super-Computers

• Super-Computers Computers used in Large organization
• Super-Computers can serve several users at ago
• Super-Computers Uncountable Micro-Processors in its Central Processing Unit

a) Specific Purpose Computers.


Specific Purpose Computers is a Computer Classification that performs a Specific Task at
ago or Time for example Computers designed to calculate wages and Salaries, Control
Stocks of goods etc


b) General Purpose Computers


General Purpose Computers is a Computer Classification that performs a General task at
ago or at a time example Computer that can perform arithmetic and Logical Operations at
At the same time.


iii. Classification of Computers By Technology


a) Analog Computers.


Analog computers use continuous data. The common available Analog Computers are:Car Speedometer – Measures Speed of the Approaching Bodies e.g. Cars

Hygrometer – Measures Humidity

Wind Anemometer – Measures Speed of the Wind.

Thermometer – Measures the Temperatures of a place.

Barometer – Measures Atmospheric pressure of a place

Voltmeter – Measures Voltage of the Electronic device.

Online Furniture System


b) Digital Computers.


Digital Computers a Computer Classification works on discrete/non-continuous data. The
Digital Computers have the capability of adding, subtracting, multiplying, dividing and
rearranges the data in predefined order they are commonly applied in Scientific and
Engineering World.


c) Hybrid Computer.


A hybrid Computer is a Computer Classification by type that performs Arithmetic and
Logical operations and at the same time measures data in the waveform.
Activity
In your surroundings, identify the types of computers in use. Are they mainframe
computers, minicomputers, workstations, or personal computers?

  • WHY WE LIVE.
    Let me at this point pose a question to you that maybe and most likely, have never thought about. As you go about your day with its many tasks, cares, and worries I think it is very fundamental to ask yourself, “What am I doing, and why am I doing it?” I’ve heard it being said that some of us are so busy making a living that we forget to live.
  • WHEN I AM GONE
    Today I am not where I was yesterday and obviously I won’t be here tomorrow. If I picture taking a journey from one point to another say from home to the work place and I walk daily for a month, you would agree with me that today it’s unlikely I will step exactly where I stepped yesterday.
  • What is the true meaning behind Christmas?
    Christmas is celebrated to remember the birth of Jesus Christ, who Christians believe is the Son of God. The name ‘Christmas’ comes from the Mass of Christ (or Jesus). A Mass service (which is sometimes called Communion or Eucharist) is where Christians remember that Jesus died for us and then came back to life.
  • WHAT IS INTROVERSION AS A PERSONALITY?
    An introvert is a person with qualities of a personality type known as introversion, which means that they feel more comfortable focusing on their inner thoughts and ideas, rather than what’s happening externally. … When you hear the word introvert, you might think of someone who’s shy or quiet and prefers to be alone.
  • What do dreams mean when you dream?
    I have often heard that there is a major connection between dreams and the spirit world. It is true that behind every dream that you experience, there is a cause or a factor. This means that perhaps you should take dreams seriously because they always carry messages that concern us and how we live
