Network admins don't program. At most, you'll need some scripting languages and experience.
Taking apart PCs in your spare time is not something that you put on a professional resume. If you have space for that kind of 'experience' on your resume, you're not qualified for this job.
Nogiri .. please, do not offer advice in this arena. You're not qualified. I mean that as politely and sincerely as possible.
HeadSetJones: that program is a decent start. It will teach you the basics. Supplement that education with experience in the field .. as a co-op, intern, or anything that you can find .. and expect to work your way up. Even work on a help desk or as an IT tech will be helpful.
I've been staring at a screen trying to find out the best way to do this. Mom, who has researched this extensively, was speaking through my account. She does have the qualifications. I do not dispute that the person normally using the "Noghiri_X" handle is not qualified.
Ok, fair enough ... please do ask your mom to use her own account when she wants to post.
However, the person who responded in this thread, regardless of their qualifications, posted what I believe was incorrect information and bad advice.
I've worked in this field for over a decade, have hired people in this field and for positions such as this, and am quite certain that no one will ever hire a Network Admin who has 'I've built my own PC' on their resume. It is the equivalent of saying "I change my own oil" when applying to a position as a mechanic.
Network Admins do not program, by and large. If a particular position does require programming, it will mention it in the ad. Someone who aspires to be a Network Admin should not worry about learning to program ... it just isn't part of that trade. Python and perl are very useful languages, to be sure, and a Sys Admin would want perl and shell scripting as part of their tool kit .. but a network admin generally isn't asked to produce code.
Network certs are a good idea, though the base education should be taken care of first. Most importantly, finding relevant work experience will help the OP get hired.
