Kinds of Computers

Mainly there are four kinds of computers. They are:


  1. Personal Computers: Personal Computers are also called Home Computers. Some people call them Microcomputers. Personal Computers are the simplest computers. They are not costly also.


Microcomputers or Personal Computers are all-rounders. They are used by professionals, record keepers, teachers, and students. Personal Computers are easily personalized to suit personal requirements. These Computers are constant companions of those who are on a mission.


  1. Minicomputers: Minicomputers are bigger and costlier than Personal Computers. They are faster and their capacity to store information is more as compared to Personal Computers. 


Minicomputers are less powerful than Mainframes. They are smaller and less costly as compared to Mainframes. 


Minicomputers are used for medium size demand. They are on duty when the problem is neither too big nor too difficult.


  1. Mainframes: Mainframes are big computers. Very powerful and very strong. They can solve big and difficult problems. 


Mainframes are used by big organisations. Critical operations of service-oriented organisations are performed by mainframes.


Such   computers are also needed when there are a number of users. These Computers perform with great accuracy in research works and are also used for military purposes.


  1. Supercomputers: Supercomputers are super. They work very fast. They are used for very difficult and very large problems. Super-duper performance is the hallmark of Supercomputers. One has to work with them exercising caution.

Supercomputers are costly. Their presence is associated with financial status. In size they can be compared to Mainframes.


Mankind is blessed to have Supercomputers. These computers have saved lives and given relief to many.

Local-Area Networks

Local-Area Networks ( LANs ) are restricted to a small area. Such Networks may be established within a building. Computers that are part of Local-Area Networks are Personal Computers ( PCs ) or microcomputers. These Computers are connected to each other. Simple communication lines connect these Pers Networks bring people together. When people join  hands teamwork becomes possible. The structural composition of LANs simplifies teamwork. In other words, LAN hardware supports teams having similar processing requirements. LAN Computers readily support personalization of tasks allocated to professionals.  Office staff can work together and share information. This improves the efficiency of the entire workforce. It has been noted that here all the Networked Computers are Personal Computers. They are of equal capacity. Mostly LAN users have similar tasks. If situations allow, a user is independent to access any Computer to serve his purpose. LAN users can exercise the option of secu...

Computers - An Introduction

Computers are man made machines. They are made to work very fast. Working fast they can solve  big and small problems.  Modern science has given us these computers. They are very popular. Computers affect and change lives. They keep us happy.The happiness grows. Computers are quick and smart. Great problem solvers and simplifiers are our computers. They can do our work without stopping. Focus is on doing only what is needed. Not needed, not done.  Computers are  life-less servants. They cannot think or make decisions on their own. They are empowered to work. They are given each and every thing so that they carry out our orders. Orders are respected by computers. The manner in which computers work is wholly dependent on man.  The quality of service provided by computers is remarkable. They are loved by human beings. Computers are known for smart and quick service. Computers do not give wrong results. Correct answers are always given. Questions which are difficult...

Euclid's Algorithm

The Greatest Common Divisor ( GCD ) of  two numbers is a number. The number ( GCD ) causes division of the two numbers. This number ( GCD ) is the greatest number that is possible. This divisor partially forms the two numbers. Adding  the divisor successively may result in formation of the two numbers. One can note that when the divisor is the greatest, the division of the dividend is the sharpest. The division operation is very effective. When the Greatest Common Divisor of two numbers is considered, we think of a number that can cause division of both the numbers. Here the two numbers are unequal. The Greatest Common Divisor causes divisions of the two numbers differently. This is clear from the two different quotient values.  The GCD value is very interesting to note. It relates very well with the two numbers. The GCD of two even numbers is also an even number. The GCD of two odd numbers is an odd number. So, we can say that GCD is an abstraction of the two numbers in ...
