Essay on Computer – For Students (Essay 7 – 750 Words)

Computers have been around in various forms for the past two centuries. Over that relatively short period of time this machine, or tool, has transformed mankind equally as much as fire or the wheel.

People have made many different tools all through history that they used to help them calculate and keep track of their resources. The idea has been around for a couple of thousand years but the technology was not advanced enough for us to make anything that resembles our modern computers till the 20th century.

The first computers were analog devices that were used for solving different problems, that is they could perform an operation based on a predetermined mechanism that was usually based on a mathematical equation. That type of computer did not have enough flexibility to be used for many tasks and it could not be reprogramed. The first digital computer was called Z3 and it was developed in 1941 after successive models were upgraded.

The age that saw the birth of the computer also saw many changes in technology and manufacturing that made computer parts available for mass use. Those developments led to the invention of personal computers that were much cheaper and easier to use and once the public got hold of them a revolution in their usage was sparked.

The Present:

The present is all about computers and almost every home in the world has a computer, or that’s what we believe. The estimate from 2015 states that over 2 billion computers are in use today. The number suggests that there are a lot of devices all over the world being used every single moment. You are probably reading this from a computer and if not, you are reading it from a device that owes its existence to the computer and electronics revolution mentioned in the segment above.

Some people have suggested that computers are having a bad influence on people because they are making us distant from each other and because people tend to spend most of their day sitting in front of the computer looking like they are doing nothing. The fact is this is not something the computer does but rather the people who use them. Like with most other things in life that give us enjoyment we sometimes tend to misuse them and cause harm to ourselves.

The fact is that the present looks like it does because of the time and resources computers have saved us and this is an undisputed fact. Without this technology, we couldn’t manage half the production process running today not to mention our daily tasks that have in some circumstances become completely dependent on this device.

The Future:

Computers are becoming more complex and at the same time simpler to use making them widely distributed with a tendency to take over the world. There are many plans for the future of computers and as time goes by, they are capable of finding solutions to complex and unimagined problems. They are used in almost all the industries from mining to hospitality management and everywhere they find a unique task, or several, that they can perform.

They have become so indispensable to our lives that some people are actually considering making them a part of their body and integrating the computer operations with the organism. This can sound a bit bizarre but people are actually making advancements in this field and cyborg devices are being implemented to help people with disabilities more often as time passes.

The potential the computer has to help us is immense and the limit is only our imagination and the resources we have at our disposal. This tool can be thought to perform endless tasks even the experts get surprised sometimes. The future looks like its full of stars but we have to keep in mind that through their use we speed up all our processes altering our existence in a sense we have to keep both eyes open for signs of potentially dangerous outcomes of some of the technological advancements we use.

Essay on Computer – History, Parts and Advantages (Essay 8 – 1000 Words)

In the wake of chipping away at his progressive distinction motor, intended to help in navigational figuring, in 1833 he understood that a considerably more broad structure, an Analytical Engine, was conceivable.

The contribution of projects and information was to be given to the machine by means of punched cards, a strategy being utilized as an opportunity to coordinate mechanical weavers as the Jacquard linger. For yield, the machine would have a printer, a bend plotter and a ringer. The machine would similarly be able to punch numbers onto cards to be examined in later. The Engine consolidated a number juggling rationale unit, control stream as contingent stretching and circles, and incorporated memory, making it the primary plan for a broadly useful computer that could be portrayed in present-day terms as Turing-finish.

Parts of a Computer:

The essential parts of a computer are the computer case, monitor, keyboard, mouse, and power cord. Each part assumes an important role in the functioning of a computer.

Computers – A Boon or a Curse?

There is no doubt that our lives have been made much easier with the introduction of computers. How easy it uses an ATM machine to withdraw money. In fact, online examinations which have removed the bias the students had to go through at the hands of teachers have been possible only with the use of computers. There are so many benefits of computers that is simply not possible to term them as a curse to our society.

However, everything must be sued judiciously, or else it does not take time for a boon to end up being a curse. For instance, we must make our kids understand the ill effects of using computers and cell phones for hours and encourage them to better reading and playing habits for them to go through their development process properly. Similarly, we must be aware of the cybercrimes one is prone to and follow the advice of the government from time to time in order to keep ourselves safe and secure from the ill effects of computers.
