Help me to know about the education system in Norway

Hi there,
Actually I don't know very much about the education system in Norway, I've searched for many articles but haven't found any situations like me yet. Plz give me helpful advices.
I got married 1 year ago and am applying visa for immigration in Norway. My husband is living in Oslo.
In my country, I graduated from high school but did not go to the university, I just learnt and got a higher diploma in computer science in 2 years. I'm going to Norway next year, I guess so, but how can I continue to study higher. I wish I can get a chance to go to university but how can I do it?
By the way, I got IELTS 6.0. I know that I have to study Norsk language and pass the exams ( I forgot the names)  before studying higher.
I don't know the way to study university in the circumstance like me. Please help me with some helpful advices.
Thank you very much
Tusen takk.

Once you've got your residency permit ("oppholdstillatelse"/"opphaldsløyve") and your language qualifications ("Bergenstesten"), then you can apply to any university through "Samordna opptak".  Their website (http://www.samordnaopptak.no/info/) gives information about what qualifications you need for the different courses.

The deadline for next year is over (1st of March for applicants with foreign education), but
Samordnaopptak.no and studyinnorway.no will give you all the information you need.

Depending where you got your diplomas, you may be granted admission with a high school diploma or some prior college education.

Thank You so much for providing me with some useful information, tiaccisaw and sctld.
