3. INTRODUCTION :
Raspberry Pi is a single board computer in the size of credit card.
By connecting peripherals like Keyboard, mouse, display to the
Raspberry Pi, it will act as a mini personal computer.
Raspberry Pi is slower than laptop or desktop but is still a
computer which can provide all the expected features or abilities,
at a low power consumption.

4. Raspberry Pi is popularly used for real time Image/Video Processing, IoT based
applications and Robotics applications.
It measures approximately 9cm * 5.5cm .

6. 1. Central Processing Unit (CPU)
It is the computer’s brain and carries out instructions using logical and mathematical
operations. Raspberry Pi makes use of the ARM11 series processor on its boards.
2. HDMI port
Raspberry Pi board has an HDMI or High Definition Multimedia Interface port that
allows the device to have video options of the output from the computer displayed.
An HDMI cable connects the Raspberry Pi to an HDTV.

7. 3. Graphic Processing Unit (GPU)
Its primary purpose is to fasten the speed of image calculations.
4. Memory (RAM)
It is where the real-time information is stored for easy access. The initial Raspberry
Pi had 256 MB RAM. The model with the maximum capacity presently is the
Raspberry Pi 4 with 8GB RAM space.
5. Ethernet Port
The Ethernet port enables wired internet access to the minicomputer

8. 6. SD card slot
The Raspberry Pi board has a Secure Digital card or SD card slot where users must
insert SD cards for the computer to function. The SD card functions like a hard drive
as it contains the operating system necessary for turning the system on. It also serves
to store data.

9. VERSIONS OF RASPBERRY PI :
 Raspberry Pi 1 Model A
 Raspberry Pi 1 Model A+
 Raspberry Pi 1 Model B
 Raspberry Pi 1 Model B+
 Raspberry Pi 2 Model B
 Raspberry Pi 3 Model B
 Raspberry Pi Zero

10. OPERATING SYSTEM
Raspbian.
Fedora.
Debian.
ArchLinux ARM.

11. HARDWARE
10/100 Base T Ethernet socket.
HDMI socket.
USB 2.0 socket.

Header footprint for camera conection.

14. APPLICATIONS :
Used in Media streamer.
 Arcade machine .
Tablet computer , Cosmic Computer.
 Home automation.
Controlling robots .
Voice activated Coffee machine

15. ADVANTAGES:
Low power
Low cost.
Huge processing power in a compact board
Many interfaces (HDMI, multiple USB, Ethernet, onboard Wi-Fi and Bluetooth, many
GPIOs, USB powered, etc.)
Supports Linux, Python (making it easy to build applications)
Complete easy to program computer

16. DISADVANTAGES :
It is slower in terms of CPU processing speed.
It does not have hard disk,so no permanent storage of files.
Complexity in multi-tasking.
RAM is not removable or swappable.
Not compatible with other OS.
