: This unit provides an overview of the "IPO" (Input-Process-Output) cycle. It details hardware components like the CPU (ALU, Control Unit, and Registers), types of memory such as RAM (volatile) and ROM (non-volatile), and the role of the system bus. It details hardware components like the CPU (ALU,

Operations like slicing, concatenation, and essential methods like append() , pop() , and split() .

Based on Sumita Arora’s detailed chapter breakdowns, focus on these critical areas:
