Grade 7, ICT, Central Processing Unit, Worksheet

The Central Processing Unit (CPU) is the brain of a computer. It processes data and performs tasks based on the instructions it receives from programs. The CPU is made up of key components such as the Arithmetic and Logical Unit (ALU), Control Unit (CU), and Memory Registers. The ALU handles mathematical and logical operations, while the CU manages data flow and communication between hardware. The CPU has evolved through four generations, starting with vacuum tubes in the first generation and microprocessors in the fourth. Modern CPUs execute millions of instructions per second, making them essential for the fast and efficient functioning of computers. Learning about the CPU helps students understand how computers work and the role of each component. This lesson introduces the concept of the CPU and its importance in the world of technology.
