Final answer:
The CPU and main memory are housed in integrated circuit chips on the motherboard within the computer, forming the core components that execute instructions and store data for processing tasks.
Step-by-step explanation:
The CPU (Central Processing Unit) and main memory are crucial components in a computer system, and they are typically housed in integrated circuit chips on the motherboard and other circuit boards inside the computer. The CPU, often known as the microprocessor, is an integrated circuit chip that implements the computer processor's functions, including executing instructions and managing data flows within the computer. The main memory, also known as RAM (Random Access Memory), is where the computer temporarily stores data that the CPU is actively using. Both the CPU and main memory are built into the computer's motherboard using integrated circuit technology, providing fast and direct access for processing tasks.
