just a little question ...?

right now i'm learning a+ certification and i wanna get a strong fundamentals in this filed
actually helpdesk is not my goal ,my really objective is information security but as i read ,it'snecessary for anyone who want
to enter in IT field to start with a+ , because that it's strange thing when you're a programmmer or developer even an ethical hacker but you don't know how computer works and how to repaire it when some problems occur ,so firstly you've to learn a+ cetification .
but when i started i found out that a+ is not enough to develope your self for example:
- when i learned about Ram and its types especially about dynamic ram ,they said in the book (dynamic refer to how bits are stored in a capacitor),in fact this is not enough to understand how bits really are stored ,and so that i search for what's a capacitor and how it works,
and definitely i found myself in other field that is electronics.
so what are your tips about this? i continue a+ then learn some electronics basics ,or cuz my passion is not about reapairing PCs just i complate a+, i move to another cert...?!

When they say learn how it works, they mean the hardware components of a computer and not how those components work in general for other things. You don't need to know how a capasitor or a transistor or a diode works to learn how to troubleshoot a bad hard drive or a bad video card or bad memory etc etc.

as i learned there is Advanced Computer Maintenance for example when a power supply doesn't work ,a+ technician will change it cuz power supply is considered replaceable unit but a professional technician is who can repair power supply and to do that ,you have to know how capacitors work and transistors.

Have you attended school majoring in the IT or Computer Science field?

I know degrees relating to computers or IT will touch upon circuits and registers. In my case I had a few classes dedicated just for circuits and logic gates, then had a class for solving registers and cpu scheduling, direct-mapping, assembly code, etc. Very hard classes as they went in depth.

Point is, I don't feel like I needed to learn any of that. Will it help me some day? I don't know yet. I guess it's nice to know how a CPU scheduler sends instructions to an array of RAM but when a user calls me saying they can't connect to the network or exchange is not working.....I don't think I can apply any of that. I think you should be fine skipping over that stuff, unless you wanted to be a Computer Engineer.

no just i teach myself(Self-education).

As a computer techician I don't think you will ever need to get inside the PSU to replace parts. Same applies to a motherboard, if capasitors in a motherboard blow up, no one will ask you to solder in new capasitors. Instead the motherboard will be replaced all together.
