Re: electronics hardware
yep.
Basic Electronics: that is the basic electronics principles(Voltage, current, Resistance etc)
Transistors,Amplifiers,Operational Amplifiers (I think googling "Basic Electronics" will give you more details)
Digital Electronics: At present the electronics is becoming faster and faster with the help of microcontrollers, microprocessors,DSP,FPGA etc.
A digital knowledge has now become a pre-requiste for a Hardware Engineer.
So you need to know the basics of Logic gates etc. (Again googling should help you better)
Once you get a lil idea about how things work, start analysing small hobby projects which are avalaible in the net or a electronics magazines(EFY/Elektor etc).
In the mean time look for the job.
All the Best!!
