     For many businessmen online education has been a dream. Now it has come true. The investment (投资) in

higher education, whether financial or in terms of time, has long been impossible for many of them. But

well-known educational institutions have chosen to deliver an internet-based program, and these barriers have

been lifted.

     That is good news for people eager to improve themselves and is more attractive to employers. It is also a

benefit to industry with better qualified candidates applying for jobs at every level.

     Having the benefits of a higher qualification without going to the university campus is attractive to many

students. Campus study means greater cost, while online programs are flexible and save time, whether at home

or at work. Students can achieve their degrees without causing too much disruption to their career or home life.

     In addition to affordable, flexible classes and greater convenience, students also have access to the online

learning resources of many of the world's top educational institutions. They can also communicate with their

tutors no matter what time it is or whether either party is away for any reason.

     This has opened up the possibility of getting a qualification from a university or college that many students

could only have dreamed of in the past. It also allows specialists to get the precise qualifications and focus on

their studies. As well as seeing the increase of applicants from lower-incomes and housewives, studying online

in the US is even becoming popular with younger people of college age.

     Employers have become increasingly welcome and positive to online qualifications as more candidates earn

them, especially if they're properly approved by the US Department of Education.

     US institutions have led the way in online education provision. Many top US colleges and universities offer

a range of online programs that are highly respected and in every way perfectly fit for adults who need to

combine their studies with a working life.
