Data Type

Grouping of data on the basis of behaviour of data is called forming a Data Type. Data Type is formed when we attempt to group data items. 

Certain Data items are closely related. These Data items are manipulated by performing same operations. We study the operations. We take a look at the Data set on which the studied operations have been performed. 

Thus formation of a Data Type isvmarked by twin activities:

1 ) Clear  identification of Data items

2 ) Study of operations that manipulate     the Data items 

Performance of operations on Data gives results. Actually operators are there to perform operations. Operators act on Data.

Students of Mathematics have observed the behaviour of Integers. We know that we can perform arithmetic operations on Integers. To perform arithmetic operations we have arithmetic operators. Examples of arithmetic operators are: '+', '-', '×', and '÷'. 

We can take any two Integers and see that arithmetic operators can be easily applied. So, we see that Integers are participants in a arithmetic operation. They play a role in the formation of result. Thus behavior of Integers affects the result that is obtained. 

This similarity of behaviour of any two integers  compared with  two other  different integers has helped the formation of Data Type - 'Integer'. Behaviour of integers is observed by the application of arithmetic operators.

The concept of Data Type serves to organize the data items. Organized data items are of great importance. Such efforts to organize has helped the Computing Community to devise novel methods for data usage. 

Providing a  long list of  data items can be time consuming and difficult. We can specify Data Type instead of opting for something that's difficult and time consuming.

Data Processing is no longer performed manually. Now Computers are Data Processors. Data Type concept  is of great help. 

We can take some samples of data items. Processing of these data items helps to understand the nature of data items. Data Type availability aids our efforts to specify a sample of data items.

Specification of data items using a Data Type is shown below:

______________________________________

Integer x, y;

x = 4;

y = 5;

______________________________________


Here 'x' and 'y' are declared to be of type Integer. According to the 'Integer' Data Type 'x' and 'y' are assigned integer values. 'x' is assigned '4'. 'y' is assigned '5'. 'x' and 'y' are actually identifiers. These identifiers are related to Data Type 'Integer'. Here identifiers that identify integers are assigned Integer values. This works.

Data Type theory is used to facilitate Computing devices to perform Data Processing.

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 ...
