The document discusses the central processing unit (CPU) of a computer. It defines the CPU as the component that processes instructions and performs calculations. The CPU has two main components: the control unit, which controls the operations of the CPU, and the arithmetic logic unit, which performs arithmetic and logic operations. The CPU interacts with other main components of a computer like memory and input/output devices through a system bus. A program is a sequence of steps where each step involves an arithmetic or logical operation controlled by a different set of signals from the control unit.

5. Program Concept
Hardwired systems are inflexible
General purpose hardware can do different tasks,
given correct control signals
Instead of re-wiring, supply a new set of control
signals

6. What is a program?
A sequence of steps
For each step, an arithmetic or logical operation is
done
For each operation, a different set of control signals
is needed
