title: What is a toolchain and a cross compiler?
body: <p>I have had confusion over this terminology for a long time. I have tried to google this question and have been getting some contradictory answers.</p>
  
  <p>One site says cross compiler is the same as a tool chain, some sites say cross compiler is a part of a toolchain. I have clearly not found this useful.</p>
  
  <p>To be specific, I have used PowerPCeabi cross-compiler and Atmel AVR toolchain. Are these both toolchains and/or cross-compilers or are they different?</p>
  
  <p>I guess, my very specific question would be, if I had to put this in my resume, will it be right in saying <code>Experienced in powerpceabi and AVR toolchains</code> ? </p>
  
  <p>Edit: For the people who marked this question as <code>unclear what you're asking</code>, how much more clear should I have to make this ? </p>
  
  <p>Modified question: Can I mention <code>powerpceabi</code> and <code>AVR</code> together as <code>toolchains</code> ?</p>
