Information Technology

Processing and distribution of data through computers,telecommunications and digital electronics is called information technology.This is an age of information technology.The world has changed into a global village.Easy access to all kinds of data across the world is the fruit of information technology.This is the most leading technology of the present age.The following are the means that are used in information technology.

Computer is the most important equipment used in it.A computer is a collection of simple machines whose activities are coordinated by a central control unit.These machines can read information and store this information for later use.Mother board,processor,ram,monitor,key board,mouse,CD ROM, and floppy derives are the main components of a computer.

As life become speedy and quick,the importance of computer has increased.It is being used in every field of life.In industry,it keeps a record of goods,cost and output.It provides a great deal of help in engineering.It designs buildings of all kinds.It gives information about the best material to be used.In medicine,it assists to perform various tests,diagnoses diseases and prescribes medicine.In space,sea and earth explorations,it has performed wonders.It collects information of various heavenly bodies,their properties, and atmospheric conditions.It tells us about the treasures hidden deep within the earth's crust and in the depth of seas.In the field of education it has performed wonders.It collects information for us from the most remote parts of the world.

Data processing is the analysis of data by using one or more computer programs.It is widely used in business,engineering,science and many other fields.Data processing is of two kinds I.E. Database processing and transaction processing.A database is a collection of common records stored in a computer.It can be searched,accessed and modified.Bank account records are the examples of such a data.Transaction processing refers to the sharing of data between computers.In this process one computer can access the data stored in other computers.

Health and Wealth

"Health is wealth" is a well known proverb often quoted by our parents and teachers. When people meet,they usually ask one another"how are you?""how are you getting on?".

There is nothing in our life that is more valuable than good health. Without health there is no happiness,no peace and no success. A person with bad health cannot enjoy the pleasure of being wealthy.

Health is more valuable than money. Money cannot buy health and happiness. But a healthy person remains in a state of bliss and happiness.

A healthy person is completely free from any illness or injury. A person with sound health also enjoys a stable health also includes a healthy mental condition. Our health depends upon several factors,such as food,pollution,sleeping habits,mental condition,air,water and sunlight. Morning walks and physical exercises are very helpful for the fitness of our mind and body. We should take proper care of our health so that we can enjoy our life completely.

On the other hand,one with good health enjoys his life. When he works or plays he is never tired. A healthy person enjoys good food and sound sleep. For him the world is beautiful and life is all joy.

A healthy person sings the glory of life and works hard to realize his dreams. He never complains. He is always happy and cheerful. He may be poor,he may have to work very hard to earn his living,but even the richest man would envy him for his good health. Health is precious and certainly a great blessing of Allah almighty. Hygienic environment,personal cleanliness,wholesome food and a regular way of life are conductive to health. Early to bed and early to rise,meals at regular times,recreation and rest are sure to make a man healthy,wealthy and wise. Young people,who have plenty of energy,need to take vigorous athletic exercises in the fresh open air. In case we are run down,overworked,or dreadfully sick we consult a good doctor. He gives us a tonic,or prescribes a special diet. "you are working too hard",he may say,"that's what the trouble is. You cannot go on burning the candle at both ends."

When we are all ill or we do not want to play or work, our bad health robs us of sound sleep and appetite. Life becomes a burden for one, who is constantly ailing. Life has little charm for him. He feels tired of life, always complaining about one thing or the other.

On the other hand. one with good health enjoys his life. When he works or plays he is never tired. A healthy person enjoys good food and sound sleep. For him the world is beautiful and life is all joy.

In the life human being health occupies an important place. Preservation of health should be the primary duty of mankind. Health is man's normal condition,his birth right. There is no yardsticks for measuring health. Health is often taken for granted and its value is not properly realized until it is lost. However,during the past few decades,there has been a reawakening that health is not merely a precious possession,but also a 'resource'. So it is desirable to maintain and promote health.

Sometime staying at one place,year in and year out,tends to make us weary and stale. It is a signal that what we need is a complete change in our environment. If we go to some other place at the hills or in the countryside,it does us to a world of good. Change and fresh air are better than all the tonics in the world. Eating out is generally avoided by health-conscious men and women. Home-made cookies are the safest and the best in the world.
