The main components of a Raspberry Pi are:

1. CPU (Central Processing Unit): This is the brain of the Raspberry Pi and is responsible for executing instructions and carrying out calculations. For example, the Raspberry Pi 3 Model B+ has a 1.4GHz 64-bit quad-core ARM Cortex-A53 processor.

2. GPU (Graphics Processing Unit): This is responsible for processing graphics and video. For example, the Raspberry Pi 4 Model B has a VideoCore VI GPU.

3. RAM (Random Access Memory): This is where the processor stores data that is currently being used. For example, the Raspberry Pi 4 Model B has 4GB of RAM.

4. USB Ports: These are used to connect external devices to the Raspberry Pi, such as keyboards, mice, and storage devices. For example, the Raspberry Pi 4 Model B has two USB 3.0 ports and two USB 2.0 ports.

5. HDMI Port: This is used to connect the Raspberry Pi to a monitor or television. For example, the Raspberry Pi 4 Model B has an HDMI 2.0 port.

6. Ethernet Port: This is used to connect the Raspberry Pi to a network. For example, the Raspberry Pi 4 Model B has a Gigabit Ethernet port.

7. GPIO (General Purpose Input/Output) Pins: These are used to connect the Raspberry Pi to other hardware, such as sensors and motors. For example, the Raspberry Pi 4 Model B has 40 GPIO pins.
