please suggest me which course is the best for me to learn computer

my friend you can get the jobby doing any aspect of computers if you're good at it. I always think that it is the interest which drives a person ahead. In the first thing which is the best part which interests you and then only you can decide on what to do. In today's world there is a big competition in every field and so if you're not a very good one and that then you are not ahead of the competition and so it is very difficult for you to get a job in a reputed company. so I think it is better that you first decide which will be strongest part. Networking is one area where you can do wonders but for that you need innovation. You had to come up with new ideas what a lot of things. Administration of systems has a very important role to play in the company's, if you can you can become a good database manager database analysis person and many more so it is you who have to think what interests you and which is the thing which you can do very well and then you should decide upon which was issued to a better job.

Take an IT course where you will learn programming, networks, and topics related to computers. If you want to deepen you knowledge then take CCNA which you will learn advanced topic about networking. I'm an IT Grad and it offers me benefits like finding a job would be an advantage.

There are many course about computer, such as system administrator,software,hardware,program maker,networking and so on.In my opinion, there is no one who can master all of them. It was suggested to choose one as your main couse .

I see that your interest is Networking and administration. I would suggest that you do either MCSE or CCNA both are more or less about networking. If you get certified then you will get a chance to work in some of the best companies as network engineer and yes the pay will also be very handsome. But make sure that you work very hard coz both the course are very hard to pass.
