DESCRIBE THE FOLLOWING TYPES OF COMPUTERS: DIGITAL,DEDICATED, MAINFRAME COMPUTERS
Mathsisfun.com describes discrete data as a type of data that can only take certain values such as the number of students in a class can only be represented as a whole number (this data can either be 40 or maybe 60 but it can never be 60.5 (this is continuous data)); continuous data is represented with values which can be rational such as the height of a person, weight or mass of a body or time in a race.
In addition Numerical Data can be Discrete or Continuous: Discrete data is counted while Continuous data is measured
When computers are classified according to their physical size, the word mainframe is always mentioned. This is a type of computer which is the second largest of all computers, only second after super computers but bigger than mini and micro computers. They are relatively more powerful in processing with large capacity in memory and storage but inferior to super computers if measured in capabilities.
