Computer Wiz

[PhelonOne87]

I really like computers and i would like to know anywhere online where i can learn from home step by step things for having a career in Computer technology im in 12th Garde graduating in 2006 from high school and want to go to college for computer career can anyone recommend anything?

Nothing will teach you more then reading and trying it out. Pick things you want to learn about and either buy books related to the matter or search online. There's LOADS of information online for everything.

i heard u need to know math if you want to get a career in computers would you happend to know if thats true?

Sure, there's lots of calculations involved in computers. Especially if you do programming or networking.

Networking involves a LOT of math when you do subnetting and programming, sometimes physics comes in useful as well.

[PhelonOne87]

CAn you give me an example of programming?

This is a distance calculation between two points on the earth using longitude and lattitude data:

pretty complicated do you have msn messenger or aim so we can talk better I Mean if your comfortable with it

It depends what you want to do? Do you want to be a programmer. Or do you want to Maintain and Repair computers. Now if you want to repair and maintain computer i recommend getting Certified with A+. Most companies wont take you unless you have a Certification in computer. Which doesnt matter because its the experience, but it helps.

[jcarle]

Certification is definately the way. Look, I know computer like the back of my hand, I've been working with them since I was a little kid. But I have no official certification, so I have a hard time getting computer related work. Most managers in companies that look for computer staff have little to no computer knowledge and have nothing but certifications to rely on when choosing their staff.

Microsoft Certifications are invaluable. MCSE, A+ and Cisco certification are all top of the line certifications.

[PhelonOne87]

If i wanted to repair and maintain computers can you give me what programs you recommend or documents I can read to start getting to know all about them or just the exact titles of things and I'll get them myself.

[matrix0978]

What i would do, is build your own PC. That will help with Repair and building. Now for maintaince, the best thing to do is learn about different programs and whats updated. Like how to repair and computer from a trojan. Or how to BIO Flash and computer, as well as reformatting. And definitly learn about the registry. Mostly learn EVERYTHING there is about a computer.

There are alot of books out there. And i highly recommend getting any computer book by The Microsoft Team.

[jcarle]

Books by Wrox for programming are my bibles (a lot of people's bibles actually...).

[ripken204]

have u taken any classes in school yet involving computers? my school has a crap load of computer classes-java,flash,html,photoshop,c++,inDesign-and they even have kinda like jobs that u can take like managing the school website, network assistant

if ur school has any classes like those then u should take some this coming year

for math like said before, programming is ALL math so if u suck at math then programming is not the way to go, ive never rly done much networking so i wouldnt know, for repair/maitenence, building a computer is a vry good way and we can help to build one if u wanted to

[Lost Soul]

all ill i add to this thread is the more complicated programming skills that you want will acquire some of the most difficult math

but yes id say get a good foundation meaning associated degree then a+ and beyond
