So much we have advanced that now every information is just a click away and is in your hands 24/7. All this advancement was possible only with the introduction of a small device called the “Computer”.

Basically, computer is a device that accepts the message by the imputer and processes this message and stores the information at the storage devices and later gives an output of the message through the output devices.

A simple explanation of the computer. Normally, a computer consists of a processing unit called the Central Processing Unit or the CPU and a form of memory. In the years between 1940 and 1945 were the first electronic digital computers developed. The initial sizes were as big as a room and consumed power as much as today’s personal computers.

Initially, computer was related to a person who carries out calculations or computations and as such the word computer was evolved in 1613 and continued till the end of 19th century. Later it as re-described as a machine that carries computations.

The early computers were limited in their functions. It was the fusion of automatic calculation and programmability that produced the first computers that were recognized in 1837. Charles Babbage in 1837 was the first to introduce and design a fully programmed mechanical computer, his analytical engine. Due to limited finances and inability of resisting tinkering with the design, he could not complete his work and it was later completed by his son Henry Babbage who made it into a simplified version of the analytical engine’s computing unit.

The original objective of inventing a computer was to create a fast calculating machine. During the World War II, it became very essential to understand and locate the direction and speed of the enemy weapons. Calculations had to be done accurately and mathematically and without an advanced machine it would not be possible. To defend the enemy , the front line soldiers required firing tables and only a computer could produce such firing tables with speed and accuracy at that time.

To produce the technology then, high sums of money and brain power was required. The first computer was produced by the Moore School of Engineering called the ENIAC, on behalf of the US Army which was in 1946. The ENIAC was able to produce the firing tables, by carrying out large number of calculations accurately.

Over a period of time computers have evolved and toady with the Artificial Intelligence technology, we use the most advanced kind of computers that have helped man in every sectors of life. At every generations of the computers or in fact during the evolution, each time computers are being launched that are lighter, smaller, speedier and more powerful. The computers have been a dominating factor since the 1970`s and today it has conquered almost all walks of life.

Apart from these in the medical sector, it provides a great helping hand in storing information that could be referred later, in space technology, automation in banks, ticket booking through the net, traffic control, and even games could be played in computers on and many more. All these are possible only because of the characteristics that a computer posses like speedy, accuracy, reliability and integrity. It could executive over a billion instructions per second without committing any mistakes is completely reliable. The memory of the computer is so vast that it could hold in a large amount of data.

To run a computer, it is the programming that decides and it should be run in a computer. Programming is defined as a set of instructions allotted to the computer that accepts it in order to solve a problem. There are many different languages that are being used to program a computer. Some of the languages are BASIC, COBOL, C, C++, JAVA are a few to name.

With the introduction of computers, attaining information has become a lot more easier. Computers have become the backbone of Information Technology and a major application in this sector is the Internet. With the Internet, nothing is impossible today.

The Recess Period in School (3 Essays)

By: Faizan Ali

Essay No.1 (584 Words)

Of course, recess time is the most enjoyable time in school after learning hard from the first period. There are two recess time in my school. These two recess time are essential for us to unwind and to fill up growling stomach.As soon as the school bell rings for recess, all students perk up. School work burden is forgotten, at least for a while. All the sorrows of being scolded and getting bad marks are forgotten. There will be a stampede towards the canteen. The junior students particularly are chattering in a jovial mood. However, there will be some students going for meetings, going to the library and the washrooms to refresh themselves. Only a minority stays in class.

The benches in the canteen at recess time are never unoccupied. Some of them even have to put their things on the tables in the canteen to ensure a seat. An advantage in size could certainly be a great help here. Every stall is always crowded with students. Some of the hawkers are not able to serve the customers at once. It is also hard to walk through the rowdy crowd in the canteen. Believe me, you will experience being pushed from one side to another.

Some hearty laugh and chat are always heard. Though recess time may seem short, it is the time for students to share endless gossip with their peers. Very often you will hear the hawkers screaming at the top of their voices to control the students from pushing and shoving. Some prefects are on duty to control these "uncivilized people". Unfortunately, it makes not much difference. And of course, some impatient students will scream out: "Quick, Auntie, quick, the bell for going back to class will ring soon."

Meantime in the library, several students are busy searching and skimming the books for extra reading and setting information for their assignments. Several students can be seen engrossed in the daily news with their best friends. The scene in the library during recess time is quiet and full of discipline although some quiet chat can be heard.

Some hard-working student or I should say bookworm will stay in their own class to finish their homework or revise. While some students are seen carrying out their cleanliness duty. You may see of a couple of girls diligently mopping the windows, sweeping the floor and cleaning the blackboard. It is certainly pleasant to study in a spick and span class room.

Some of the students will also enjoy walking around the passageways in front of the classrooms or in the park chatting with their peers. Some younger students who have not 'tasted' school work pressure play hide and seek with their friends. While the older ones are deep in thought in some corners. A few are seen trying to solve additional Maths or Physics problems. Certainly, one will also see some pupils running here and there along the passageway while the others just loiter around.

In the wash rooms, you may find some students washing their faces to refresh themselves after studying hard since morning. Some even have to stand in a queue for a while to use the toilets. The toilets are never unoccupied. Each class has is specified for its own toilet.

All in all, I can say that the scene in my school during recess time is one of noise and many students. Students enjoy their own activities during this time. I, myself, enjoy every moment of recess time very much.

Recess means a period of relaxation. It comes after four periods continuous study. So everybody likes it after hard work. The recess period comes usually in the middle of the school hours. Its object is to allow some time to the teachers and the taught to refresh themselves mentally and physically.

Sometimes, before the recess period, the students feel bored. They become inattentive to the lessons. They no longer follow the teachers. They grow tired of their lessons. They look forward to the recess period. Some of the naughty boys approach the school peon and ask him to ring the bell. All this shows that change is badly needed.

As soon as the recess bell goes, all the boys shut their books and put them in their bags. They go out. This action of the boys sometimes makes the teacher angry. But they cannot help it. They want to be free for some time. They wish to remain away from the dull atmosphere of the class.

When the students come out of their classrooms, they relax them- selves in different ways. The boys of rich families enjoy nice things- sweets, fruit or milk which their parents send for them. The boys belonging to middle class families eat some cheap things, which they buy from the hawkers, who reach school by the time of recess period. The poor boys generally bring food and eat it in the classrooms. Some schools have canteens. No hawker is allowed in the campus. We get tea, fruits, and other things in canteen. Rates are fixed. Seats are neat and clean.

Having satisfied their hunger for recreation boys sit in groups and talk about many things. Sometimes subject of their talk is some teacher whom they hate. At other times, it is some unpopular boy. At times, however, they talk of politics. The students of lower classes play with balls in the playground. Very often they use their time in laughing and merry making. Some weak or absent students complete their home work.

As soon as the recess period is over, the happy mood of the students goes away. They become serious again. They run to their class rooms, lest they should be late, because they have their second attendance. Recess period has become a regular feature in everyday life. These days there is an interval of half an hour in almost all offices. Nearly all the shops in the towns also enjoy lunch time.

During winter, the lawns are full to their capacity. In summers, there is a great rush at the water-taps and the water-coolers.

I finish my refreshment and then rush to the reading- room. The students read newspapers and magazines. If I am late then it is difficult to get a seat.
