There are many paths to certification and the first step is to do some research. Spend some time defining your current skills, deciding where you want to take your career, and then look at the certifications that are applicable to your goals.
Primarily the one given a certification benefits more. Being certified means one can properly function on a certain job. This means, companies will easily hire a person with certification especially when certifications come from a reliable learning institution. In some ways, the company to which a certified person intends to apply for work will also benefit since the performance of the applying employee is being supported with a certification.. If you are an expert, a certification is proof. If you are not yet an expert, the path you must take to become certified will provide you with the tools to become one. Hence certification is what you need to prove your worth. You may be real good, but how will the world know that? What is the guarantee, proof or degree? Hence the need for certifications!
There is no universally accepted way to prepare for a job as an Information Technology (IT) Professional than through Microsoft Certifications. Although a bachelor’s degree is often required and relevant work experience is very important, many people develop their computer skills while working in other fields. The continual study of new technologies is necessary to keep computer skills current.

What does free online information technology computer certification training offer that would be beneficial for the student who plans on passing there IT certification exam on the first attempt? Free computer certification training can only take you so far. You will learn the basics but you will not know enough to pass a certification exam. Many Websites will give you free training in order to draw you in, so you will purchase some training material (study guides, online tutoring and practice exam questions).
Many computer institutes have been offering different kinds of online computer training programs to their students. These are specially designed, keeping the industry needs and requirements in mind. As more and more companies require high level and trained IT staff for their companies, it has forced many employees to take up such computer training programs that can improve their career growth in different areas. There are very few resources available online or classroom in which you will be able to find the appropriate certification exam training. Knowing how to take a test and apply the learning that you have acquired is an art that can be learned also. Information technology computer certification exam taking requires skills that you can easily pick-up by using the right exam training material.
Computer training courses can also be useful to those who have a keen interest in this area and wish to take it up as their profession. There are many programs that are offered for students who wish to specialize in different areas giving them good flexibility of learning at their own pace.
A certification may help your career. Nowadays, competition in the jobs is getting tougher. For one to stay in his or her job or to be promoted to a higher position, one factor to consider is his or her educational achievements. That is one reason why mastering your field of work by means of studying and training can be a great boost for your career. That is where a certification program can make or break your career advancement.

CS610 (S) : FOUNDATION COURSE IN ENGLISH FOR COMPUTING
Time: 2 hours
Maximum Marks: 50
Note : Attempt all the questions.
1. Read the passage and answer the questions that follow :
As human civillzations have changed from agrarian to industrial economies, they have become increasingly dependent on fossil fuels (petroleum, coal and natural gas) and derived forms of energy (heat and electricity). Early agricultural societies depended entirely on the energy of sunlight to grow food, and the energy of physicai labour for its cultivation and harvest. Domestic animals, introduced later, converted food energy into fats, fibres and proteins and provided greater physical strength to draw ploughs, pull carts and turn waterwheels. These early societies obviously did not require electricity or combustion engines to drive machines.
The invention of the electric motor and the internal combustion engine in the nineteenth century changed this orientation completely. Firstly, these machines were a startling boost to productivity. They enabled man to do far more work and to cultivate and harvest greater acreage. Secondly, machines replaced draft animals, with the result that modern agricultural operations became dependent on petroleum and electricity. An absence of either one would be disastrous to present food production throughout much of the world.
Essentially the same transition has occurred in energy requirements for industrial, transportation and domestic needs. One hundred years ago, electricity was a novelty, automobiles were a freakish invention and the diesel truck was unknown. Since then, all three have become essential. A modern city cannot exist without electricity and petroleum. Within another hundred years we will have to find alternatives for the latter, since the world’s reserves will not last that long, but our need for electrical energy will continue to rise.

5. Read the passage and summarize it to one-third of its length. (10)
The newspaper has always taken upon itself the role of mentor to its subscribers, but whereas the journal of the last generation took pride in its independence, and the editorial chair was regarded as a pulpit from which serious views were uttered with a full sense of responsibility, the newspaper of today is a huge financial undertaking with the same outlook as any other limited company. The editorial staff have to run me concern so as to produce dividends for the shareholders; in other words, they have to make circulation, and if they do not they will soon be supplanted by those who can. Their independence therefore suffers a very grave limitation. It is further curtailed by the fact that a newspaper is as much an advertising medium as a vehicie for news. It is said that the price which the public pays for its newspapers covers no more than a third of the cost of production; the other two-thirds is accounted for by advertlsement revenue. The need for rnaintaining the value of its advertising space in competition with its rivals makes it all the more important for a paper to raise its circulation to the utmost. Thus, as a matter of editorial policy, it becomes much less necessary to instruct readers of the latest move of the Government than to persuade them of the advantages they will secure if they become registered, insured subscribers and are forlumate enough to lose a relative in a railway accident.
After two generations of compulsory schooling, which has at least taught everyone to read, the business of forcing circulations up above the million mark has not been difficult once the method was discovered. The last Lord Northcliffe showed the way with the Daily Mail in the nineties. He saw that there was a vast body of people who were not attracted by the newspaper that catered for the professional man and the club member, but who would be eager to buy a Journal that would deal in an interesting and arresting fashion with the things that were reah a part of their lines. He realized that unparalleled success awaited the newspaper that would reduce politics to a minimum, provide chatty articles on sport, hobbies, and everyday interests, substitute literary and theatrical gossip for serious criticism of books and the stage, and, above all, appeal to the special interests ol women. Once this new policy had been put into practice, its commercial value was obvious enough. The other papers were bound to follow the lead of the Daily Mail sooner or later. The process was hastened by the influence of American journalistic methods. Since the War the transformation of penny journals has proceeded with sudden acceleration. ln reaching out to an ever-wider public belonging to the lower cultural levels, mosi of them have rapid9 dropped in intellectual and literary quality until now they scarcely pretend to appeal to people of intelllgence. They provide news and views, not for their own sake, but as a means of purveing a daily dose of entertainment that will save readers the trouble of turning to books.
6. Write a composition in about 300 words on any one of the following topics : (10)
(i) The negative impact of technology
