What does the term 'register allocation' refer to in code generation?

Step 1: Understand that a CPU has a limited number of registers, which are small storage locations for quick data access.
Step 2: Recognize that variables in a program need to be stored somewhere for the CPU to use them.
Step 3: Learn that 'register allocation' is the process of deciding which variables should be stored in these fast registers.
Step 4: Realize that the goal of register allocation is to make the program run faster by minimizing the time it takes to access variables.
Step 5: Know that good register allocation can lead to better performance of the program.
