DESCRIBE THE FOLLOWING TYPES OF COMPUTERS: DIGITAL,DEDICATED, MAINFRAME COMPUTERS

2. DIGITAL COMPUTERS

This is a digital computer; computers that process data which is discontinuous (discrete) in nature. Yourdictionary.com further adds that, these are computers that process data which is inform of digits called binary digits represented by 0s and 1s

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

2. DEDICATED COMPUTERS

Dedicated computers are general purpose computers however these computers are devoted to carry out one task only. For instance, a general purpose computer can be devoted for accounting in a bank or office, as a teaching aid in a school or for graphic editing in a studio or engineering firm.

3. MAINFRAME COMPUTERS

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.
