Classification of computers Classification of computers Presentation Transcript

  • Classification of computers There are basically three main ways to classify computers. These are: By Type By Purpose By Size/ Capacity Dominic Boye Jnr.
  • By Type There are three main types of computers under this class. They include: Digital computers Analogue computers Hybrid computers bitsgh@gmail.com
  • Digital computers These are computers that represent data /information in a binary form. That is they represent signals in just two states. 0s and 1s are used during data communication. bitsgh@gmail.com
  • bitsgh@gmail.com
  • Examples of digital computers o Desktop computers o Laptop computers o Mobile phones o iPads o iPhones o Scientific calculators bitsgh@gmail.com
  • Analogue computers These computers represent data/information in a continuous form. That is there are no breaks during signal transmission. They represent information by processing measurable physical quantities. bitsgh@gmail.com
  • bitsgh@gmail.com
  • Examples of analogue computers o Speedometer o Thermometer o Conventional watch bitsgh@gmail.com
  • Hybrid computers These computers exhibit features of analogue computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analogue component normally serves as a solver of different equations. bitsgh@gmail.com
  • Examples of hybrid computers o Automated teller machine (ATM) bitsgh@gmail.com
  • Examples of hybrid computers o Electrocardiogram bitsgh@gmail.com
  • By Purpose Computers can also be classified according to the purpose or application to which it is put. There are two(2) main groups under this category, these are: o Special purpose o General purpose bitsgh@gmail.com
  • Special Purpose Computers A computer is said to be special purpose if it is designed to solve a specific class of problem for which it was made. bitsgh@gmail.com
  • Examples of special purpose computers Computers for chemical processes. Computers in digital watches. bitsgh@gmail.com
  • General Purpose Computers A general purpose computer is not limited to the number of applications it can be used for. bitsgh@gmail.com
  • By Size/Capacity The capacity of a computer refers to the volume of data or information it can process or store and the speed at which it works. The three main computers under this group are: Macro Computers Mini Computers Micro Computers bitsgh@gmail.com
  • Macro Computers They are the largest of all the computers in terms of price, memory size, power and speed of processor. Characteristics:  Very expensive  Generate a lot of heat  Large memory size  Wider variety of peripheral support.  Supports multiple users bitsgh@gmail.com
  • Examples of Macro Computers Mainframe bitsgh@gmail.com
  • supercomputer bitsgh@gmail.com
  • Micro computers They are the smallest of all the computers. They are also called Personal Computers because they are used by one person at a time. Characteristics:  Small in size  Used by one person  Generate less heat  Not expensive bitsgh@gmail.com
  • Examples of Micro Computers Desktop computers Laptops Workstations IPads Mobile phones bitsgh@gmail.com
  • Mini Computers A mini computer is one whose size, speed and capacity lies between those of macro computers and micro computers bitsgh@gmail.com
